The following goals were taken into account during development: • The instrument cluster is an integral part of the iDrive/Driving Area. • All of the necessary information for driving the vehicle must be on display in the direct field of vision of the driver in a simple and easily understandable form. • Display technology with outstanding ergonomics due to graphic displays. • New type of Check Control system with clear, understandable texts and graphic symbols. With these goals realized, the instrument cluster has become a multifunctional display unit that links the benefits of various display technologies into a single unit. kt-8856 3 E65 Instrument Cluster Hardware The instrument cluster is designed as a complete integrated component and secured to the dashboard with three screws. It is connected to the vehicle communication system via the data buses: K-CAN System and MOST. The display of road speed and engine speed is by means of pointer instruments. The point¬ ers are moved by stepper motors. The pointers move over an LC display. kt-8761 The fuel and temperature gauges have been deleted from the instrument cluster and are now an On-Board Computer and Check Control display respectively. The scale and labeling of the tachometer and speedometer are printed on a frame and placed over the LC display. The legally required displays are in the form of fixed-position, standardized indicator and warning lights. The indicator and warning lights are arranged between and next to the pointer instruments. The indicator and warning lights as well as the back light of the LC display use single color and multi-color LEDs. The light emitting diodes are designed to last the service life of the vehicle and cannot be replaced. All other displays and messages (e.g. those of the on-board computer) are represented on the LC display, which is visually divided into six display fields by the frames of the pointer instruments. The control unit is integrated in the instrument cluster. The control unit consists of a high- performance 32-bit computer for the display and lighting as well as the BC and CC func¬ tions. Another 8-bit computer is responsible for activation of the pointer instruments and the fixed-position indicator and warning lights. 4 E65 Instrument Cluster A memory of 4MB for the U.S. instrument clusters is used to store the language and units variants. Language and units can be changed using the Control Display. The following languages and units are stored in the language memory (4 MB) of the instrument cluster: Languages • German • English (UK) • English (US) • French • Italian • Spanish Units • Temperature in °C, °F • Consumption in mpg US, mpg UK, km/I, 1/100 km • Date / time format for US/ECE • Distance in km, miles Depending on the country code stored in the Car Access System (CAS), a language pack¬ age consisting of three of the languages listed above is programmed in the CD. A language can be selected from these three languages in the CD. For U.S. versions the selectable languages are English (U.S.), French and Spanish. The setting of units and languages can be saved as a key memory function. This means that the units and languages are displayed automatically depending on the key used (user). Integrated Functions of the Instrument Cluster • Pointer instruments for road speed and RPM. • Indicator and warning lamps. • On-board computer (BC). • Check Control CC. • Test functions. • Time signal source (time master). • Dim signal source (dimmer master). • Outside temperature signal source (outside temperature master). • Turn signal indicator acoustic output. • Codable memory for languages and units. • Fault code memory. 5 E65 Instrument Cluster Components Display Areas of the Instrument Cluster The instrument cluster uses three main display devices: • LC display • Pointer instruments • Warning indicator lamps (LEDs) LC Display 3 5 6 4 kt-8989 The LCD unit is the digital display area. A frame placed over the LCD unit visually sepa¬ rates it into six display areas for the indicator and warning lamps. A special feature here is that holes had to be drilled through the LC display for the connection of each pointer instru¬ ment (speedometer and tachometer). In order to ensure that the LC display can also be read easily at low temperatures, the dis¬ play is heated. The heating consists of heating wires on a sheet behind the display. When the driver's door is opened, the switch-on signal is sent by the CAS via the K-CAN System bus to the instrument cluster. The display heating is activated at temperatures below 10°C (50°F). 6 E65 Instrument Cluster Display Area 1, Inside the Speedometer In this display area, the following content can be displayed in the form of text and graphics: • Speed limit warning field • Cruise control • Test functions • Condition Based Service (CBS) reset Speed Limit Warning Field In order to prevent the speed limit from being exceeded, the driver can use the On-Board Computer to set a desired speed limit. When the speed limit is set, an illuminated bar segment beginning at the set limit appears in this display area. The circle segment starts at the desired limit and extends to the scale limit. If the set limit is exceeded, an acoustic signal sounds. Cruise Control The cruise control offers the possibility to save speed points which can be activated when required. This enables easy selection of speeds that are frequently required, for example 55, 65, 70 mph at the push of a button without having to go to precisely to that speed and then set it. Up to 6 speed points (dots) are possible. When the cruise control is active, a bright arrow marks the speed currently set for control. If the cruise control has been deactivated (e.g. after braking), the speed points to which the control was last set (while driving) is marked by a dim arrow. 7 E65 Instrument Cluster Test Functions The trip distance reset button can be used to select a total of 21 test functions in display area 1. The content of the test function appears in display area 2. The test functions are described in detail in Workshop Hints. 1 2 kt-8987 CBS Reset The trip distance reset button can be used to select the CBS reset functions in display area 1. The content of the functions appears in display area 2. The CBS reset functions are described in detail in Workshop Hints. 1 2 8 E65 Instrument Cluster Display Area 2, Inside the Tachometer In this display area, the following content can be displayed in the form of text and graphics: • Variable engine speed advance warning field • Navigation display • Diagnosis test functions Variable Engine Speed Advance Warning Field The scale of the tachometer contains a fixed (painted) engine speed advance warning field (dashed red) with subsequent engine speed warning field (continuous red). In addition, similar to the M5, the display area contains a variable engine speed advance warn¬ ing field below the engine speed scale. Here, depending on the engine temperature, a maximum engine speed recommendation is displayed to the driver. When the engine is at operating temperature this display disappears. Navigation Display Guidance information (round arrow), the next junction and the distance to the next junction are displayed. Up to a point shortly before the turn-off, the distance to it is showed numer¬ ically. It is then displayed in a bar chart. The bar decreases in size continuously until the turn-off is reached. Whether the distance to the next turn-off is displayed numerically or as a bar chart is determined by the naviga¬ tion system. The data is transferred from the navigation system by MOST bus telegram to the instrument cluster. E65 Instrument Cluster Display Area 3, Below the Speedometer In this display area, the following content can be displayed in the form of text and graphics: • Service requirement display (SBA) • On-board computer (BC) (fuel gauge, range) If there are no messages from the SBA, the fuel gauge or (depending on setting) range is dis¬ played here. Pressing the BC key on the turn indicator switch toggles between the BC displays. kt-9334 Display Area 4, Below the Tachometer Both BC and CC text messages are shown in this display area. The BC text messages are overwritten by the CC text messages. Most CC text messages are supplemented by a symbol matching the message being displayed in the variable display and warning field (dis¬ play area 5). 10 E65 Instrument Cluster Display Area 5, Variable Display and Warning Field This area serves as a variable display and warning field. In this display area, the following content can be displayed in the form of text or graphics: • CC warning symbols • Outside temperature • Time kt-9226 CC Warning Symbols Each CC text message (in display area 4) is assigned a symbol that appears in the variable display and warning field. The warning symbols are displayed in red or yellow. If there are no CC messages, outside temperature and time are displayed here permanently. Outside Temperature If the temperature falls below +3 °C (37°F), a CC message with acoustic warning is issued. The outside temperature is calculated and displayed by the instrument cluster taking the factors of engine-coolant temperature and vehicle speed into account. Time There is an integrated quartz crystal clock in the instrument cluster. The time appears in display area 5 of the instrument cluster and can be set manually by the driver using the con¬ troller in the CD. The display of time and outside temperature takes place as of KL R ON. 11 E65 Instrument Cluster Display Area 6, Gear Display When using the “Low” mode, the gear engaged by the gearbox is displayed in this display area (LI to L6). Steptronic will be available in the U.S. later in production, with the intro¬ duction of the 745i sport and 760Li. In the Steptronic mode, the gear engaged by the gearbox is displayed in this display area (Ml to M6). In driving program position D and activated S program, an S is displayed here. 6 kt-9228 Pointer Instruments Speedometer The speedometer scale and the scale lettering are shown on the fixed-position dial. The pointer is moved by a stepper motor. The speed signal goes from the DSC control unit via the PT-CAN to the ZGM and from there via the K-CAN System to the instrument cluster. The signal from the left-hand rear wheel sensor, as processed by the DSC control unit, is used here. 12 E65 Instrument Cluster Tachometer The tachometer scale and the scale lettering are shown on the fixed-position dial. The dial of the tachometer contains a fixed engine speed advance warning field (dashed red) with subse¬ quent engine speed warning field (continuous red). The pointer is moved by a stepper motor. The engine speed signal goes from the DME (ECM) via the PT-CAN to the ZGM and from there via the K-CAN System to the instrument cluster. kt-8917 Indicator and Warning Lamps The indicator and warning lamp are arranged in fixed positions between and beside the pointer instruments in the instrument cluster. For activation, the symbols are given back¬ ground lighting (LEDs) in one or more colors. This enables display of symbols depending on the degree of importance in red, yellow, green or blue. The legally required and stan¬ dardized indicator and warning lights include: • Turn indicators • High beam headlight • Seatbelt warning • Airbag • General brake warning • Rear fog lights, fog lights • OBD II Check Engine (MIL) There are also indicator and warning lights for: • Dynamic Stability Control (DSC) • Program display of the automatic gearbox 13 E65 Instrument Cluster kt-8923 The arrows beside the program display indicate each of the possible directions of move¬ ment of the transmission selector lever. The program display remains illuminated for 10 seconds after the remote control has been removed (after-run function). When the engine has been switched off (KL15 OFF) and drive position N selected, the pro¬ gram display remains active for up to 30 minutes. This indicates to the driver possible incor¬ rect operation of the selector lever on parking the vehicle (position P not engaged). After 30 minutes have elapsed, the parking lock is activated automatically. The entire control of the program and gear display is handled by the EGS control unit. All other indicator and warning information is provided in a corresponding symbol display in the variable warning field. 14 E65 Instrument Cluster Illumination and Dimming The background light of the display areas and the lighting of pointers and dials is provided by orange LEDs. The light emitting diodes are designed to last the service life of the vehi¬ cle and cannot be replaced separately. The individual display areas are only illuminated when there is a message displayed in the relevant display area. However, for reasons of visual appearance, two adjacent display areas are always illuminated at the same time. The pointers and dials are only illuminated when the lights are switched on and they serve as a function indicator for "driving light ON". The brightness of the LCD display as well as all indicator and warning lamps is adapted to the lighting conditions in each case using a phototransistor. \ 1 kt-8862 The brightness signal is calculated in the instrument cluster from the values of the photo¬ transistor (1) and the dimmer wheel. This brightness signal is also made available via the K-CAN System to other control units in the vehicle. The instrument cluster is thus used as the "dimming master". The contrast setting of the LC display is automatic, depending on age and temperature. For the temperature compensation, an NTC resistor is fitted to the LC display. The contrast voltage is then determined according to the temperature by the electronics in the instru¬ ment cluster. In order to take account of ageing over time, a counter is installed in the instrument cluster to record the operation time by the hour. With increasing age of the LC display, the contrast voltage is adapted to maintain a consistent contrast. 15 E65 Instrument Cluster Turn Signal Acoustic Feedback The turn signal acoustic feedback is output through a loudspeaker integrated in the instru¬ ment cluster. All other acoustic signals are generated by the Audio System Controller ASK and output through the vehicle loudspeakers. Trip Odometer Reset Button The trip odometer reset button is located in the top left-hand corner of the instrument clus¬ ter; it takes on the following functions: • With the ignition switched off, brief pressing of the button displays the total mileage, the trip odometer, the time and outside temperature for 8 seconds. If the button is pressed once again within this time window, the trip odometer is reset. • Pressing the button for longer than 2 seconds displays the ABS symbol for 2 seconds in the variable warning field. • Activation of the test functions. • Resetting the service requirement display SBA 2 1 ■TAj * ' 1 ' | LU •1 . it . m . * VrC//-- * kt-8803 16 E65 Instrument Cluster Input and Output Signals The connection of the instrument cluster to the vehicle electrical system is by means of a 20-pin Elo connector.

CAN The communication with control units in the chassis, power train and body areas is via the K-CAN System. Via the K-CAN System, the following input and output signals are transferred in the form of telegrams: Speed This telegram is required for the display of the vehicle speed and the calculation of the dis¬ tance driven. The signal from the left-hand rear wheel sensor processed by the DSC con¬ trol unit is used. The speed telegram goes from the DSC control unit via the PT-CAN to the ZGM (Central Gateway Module) and from there via the K-CAN System to the instrument cluster. Gearbox Data Via this telegram, the instrument cluster receives the following gearbox data from the AGS control unit: • Gear position • Driving program • EGS error messages This data is used to display the gear position, the selected driving program and CC mes¬ sages. The gearbox data telegram goes from the AGS control unit via the PT-CAN to the ZGM (Central Gateway Module) and from there via the K-CAN System to the instrument cluster. 19 E65 Instrument Cluster Engine Speed (RPM) The engine speed telegram goes from the DME(ECM) via the PT-CAN to the ZGM (Central Gateway Module) and from there via the K-CAN System to the instrument cluster. Outside Temperature The input value of the temperature sensor is computed in the instrument cluster against the current engine temperature and the vehicle speed. This ensures that the outside tempera¬ ture signal is not excessively influenced by the air flow or the engine heat. The instrument cluster makes this outside temperature value available to the other control units (e.g. CD, IHKA) as a telegram via the K-CAN System. CBS Messages These telegrams are sent by the following components - which monitor their own wear parts within the framework of Condition Based Service CBS - to the instrument cluster: • DME (ECM) • DSC • IHKA These signals contain the current degree of wear of each component and are used in the instrument cluster for calculation of the CBS displays and service dates. Bus Status The ZGM informs the instrument cluster about the status of the K-CAN System, (e.g. bus active, bus in idle state). Dimming This signal comes from the dimmer wheel and is sent by the light module LM via the K-CAN System as a telegram to the instrument cluster. Driver Display, speed range This telegram is routed from the DME (ECM) via the PT-CAN to the ZGM and from there via the K-CAN System to the instrument cluster. The signal is used to show the variable engine speed warning field in the display of the instrument cluster. Parking Brake (EMF) The telegram for the parking brake indicator lamp is routed from the EMF control unit via the PT-CAN to the ZGM and from there via the K-CAN System to the instrument cluster. 20 E65 Instrument Cluster Vehicle Identification Number This telegram is routed from the Car Access System (CAS) via the K-CAN System to the instrument cluster and it contains the last seven digits of the vehicle identification number. The vehicle identification number must be specified within the framework of the redundant data storage for the allocation of instrument cluster to vehicle. Vehicle Type This telegram is routed from the Car Access System CAS via the K-CAN System to the instrument cluster and it contains the following details of the vehicle type: • Model series • Body type • Gearbox • Engine type • Steering • Country-specific version This enables an allocation between the various vehicle versions and the instrument cluster. Mileage Reading/Range This telegram is made available by the instrument cluster via the K-CAN System to other control units. It contains the following details: • Total mileage • Tank level status, right, left, total, reserve • Calculated range These details are required for creation of fault code memory entries in other control units. Terminal Status This telegram is routed from the CAS via the K-CAN System to the instrument cluster and it contains details of each terminal status: • Status terminal R • Status terminal 15 • Status terminal 50 • Status key in ignition 21 E65 Instrument Cluster Lamp Status This telegram is routed from the LM via the K-CAN-System to the instrument cluster and it contains details of each lamp activation: • Status high beam/headlight flasher • Status parking light • Status fog lights • Status rear fog light LCD Brightness This telegram is calculated from the value of the phototransistor and the dimmer wheel. It is routed from the instrument cluster via the K-CAN System to the control units: CDC, SZL and LM, it is used by these control units as a dimming signal. Engine Data This telegram is routed from the DME (ECM) via the PT-CAN to the ZGM and from there via the K-CAN System to the instrument cluster; it contains the following details: • Engine temperature (coolant temperature) • Engine oil temperature • Engine oil pressure • Alive counter of the DME (function monitoring of DME) • Status engine running • Injection rate (total of supplied volume of fuel) Network Management K-CAN This telegram is transmitted and received by every control unit. For this purpose, each con¬ trol unit has a corresponding control unit address that it uses for transmission and by which it recognizes a network management message. RDA Request/Data Storage Via the K-CAN System, the instrument cluster requests the current data from the redundant data storage in the CAS. The same telegram is used to transfer the latest data of the instru¬ ment cluster to the CAS. Cruise Control This telegram is only sent by the DME when no ACC is installed; it contains the following information: • Current control speed • Status of the cruise control (off/activated) • Display of speed marks 22 E65 Instrument Cluster Power Management Battery Voltage This telegram is routed from the Power Module via the K-CAN-P via the K-CAN System to the instrument cluster and it contains the following details: • Battery voltage • Status battery main switch Relative Time This telegram is made available to other control units by the instrument cluster for time cal¬ culations. A timer counts the seconds synchronous to the system/vehicle clock. This sig¬ nal can be used to measure relative times. The clock cannot be used for this purpose, as it can be set by the customer. The counter runs following reset (e.g. disconnecting the battery) from 0 and counts in sec¬ ond increments from 0 to over 4 billion, which corresponds to approximately 140 years. The DME (ECM), for example, needs the relative time to determine the immobilization peri¬ od of the engine (engine OFF) and thus to improve the starting capability of the engine. The immobilization period is calculated by the DME (ECM) from the relative time of terminal R OFF to terminal R ON again. Status Damper Program This telegram is routed from the Electronic Damper Control-continuous (EDC-K) via the PT- CAN to the ZGM and from there via the K-CAN System to the instrument cluster. If the EDC-K fails, active output of error messages is no longer possible. Monitoring means the instrument cluster is able to detect failure of the EDC-K and to display a corresponding Check Control message. Status DSC This telegram is routed from the Dynamic Stability Control DSC control unit via the PT-CAN to the ZGM and from there via the K-CAN System to the instrument cluster, informing it of the status messages of the DSC program and error messages. Alive Counter EMF This telegram is routed from the electro-mechanical parking brake EMF control unit via the PT-CAN to the ZGM and from there via the K-CAN System. It serves as function monitor¬ ing of the EMF by the instrument cluster. If the parking brake control unit fails, active out¬ put of error messages is no longer possible. Monitoring means the instrument cluster is able to detect failure of the parking brake control unit and to display a corresponding Check Control message. 23 E65 Instrument Cluster Time/Date This telegram is made available by the instrument cluster via the K-CAN System to other control units and it contains details of the date and time. The wiper module, for example, needs the information date/time to calculate the alternating rest position for the wiper sys¬ tem. Status Radio-Control Key This telegram is routed from the CAS control unit via the K-CAN System to the instrument cluster and it contains the following details: • Personalization number of the radio-control key • Status key battery Status Instrument Cluster This telegram is routed from the instrument cluster to the control units, DME, SIM and wiper module, it contains the following details: • Displayed vehicle speed • Unit of speed kmh/mph • Fill level, washer fluid • Status interface cruise control • Status airbag warning lamp • Relative time counter • Status seatbelt warning lamp • Status engine warning lamp • Status DSC indicator lamp • Status brake warning lamp • Status parking brake indicator lamp 24 E65 Instrument Cluster Central Locking System and Trunk lid Status This telegram is routed from the CAS control unit via the K-CAN System to the instrument cluster and it contains the following details: • Status central locking system • Control central locking system • Status door contacts and trunk lid These signals are required by the instrument cluster for the display of the CC message regarding the positions of doors, trunk lid and central locking system. MOST bus The data connection to the following control units in the communication area is via the MOST bus: • Navigation system • Audio System Controller (ASK) • Speech Processing System (SVS) • Control Display (CD) 25 E65 Instrument Cluster Check Control Until now, the Check Control has been a reporting system for vehicle faults. For the E65, the scope of functions has been extended considerably. It now also displays operating statuses and provides detailed instructions. This provides the driver with valuable assis¬ tance, enabling the appropriate reactions in the event of a system failure or fault, despite the increasing complexity of the vehicle electronics. In the E65, the number and information content of the messages have increased consider¬ ably in comparison to the E38: • Most CC messages contain a unique instruction, telling the driver what to do. • The message texts are more detailed (40 characters instead of 20 in the E38). • Parallel to the CC message, the On-Board data menu of the Control Display contains more detailed information (up to 170 characters!) regarding the current message. In the case of particularly important messages, this appears automatically. • The combination of text and graphic ensures faster assimilation of the information on the part of the driver. • The number of warning indicator lamps in the instrument cluster has been drastically reduced; many of them have been replaced by more informative CC messages with variable indicator lamps. Warning lamps are now only used where this is legally required. • The Check Control is easy to expand, as the evaluation of the message conditions for the individual functions and systems has been shifted to the relevant control unit in each case. • The coolant-temperature gauge in the E65 is no longer a separate instrument, but a function of the Check Control. It is only displayed when required. 26 E65 Instrument Cluster Display Locations The messages of the Check Control are displayed in three locations. Display Area 5 Display Area 4 • Graphic icons • Short text message ■s ro ft < % .T. •IV-r. llt.M 1 f.7.^ BlHHlW u. -Util nr..,|L TKI HI MAUK HotftmfcbtHi. ‘iiM'-f nuliit«:-ijnkilur-;| Wwlprlvihil l>i i Inqi. mftglKh. unKf*l“*nri \\ \ Control Display • Extended text messages kt-9376 The variable graphic icons are displayed in yellow or red in display area 5 below the gear display. Normally, the time and outside temperature are displayed in this area, these can be overwritten by the Check Control where required. The text messages of the Check Control appear in display area 4 below the tachometer. If data from the On-Board computer is displayed here while a message is being issued, it is overwritten by the Check Control. For most of the messages of the Check Control, there are also supplementary explanations and instructions. These can be opened on the Control Display via the On-Board Data menu. In the case of priority 1 messages, they appear automatically. Check Control messages are most times announced by a gong. Display Characteristics All messages of the Check Control are triggered by the control units responsible for the monitored function and transferred as data telegrams via the MOST bus or the K-CAN System to the instrument cluster. From there, they are distributed, depending on requirements to the individual output locations (within the instrument cluster or via MOST to the Control Display). 27 E65 Instrument Cluster Each individual CC message is assigned characteristics that control its display features. At this point a distinction is made between text messages (in addition to an indicator lamp, an accompanying text also appears in the Check Control and possibly also on the Control Display) and non-text notifications (a warning LED or graphic icon lamp lights up). All the message texts are stored together with the characteristics in a table in the instru¬ ment cluster. In the event that a number of messages are output at one time, the message with the highest priority is displayed first. The same applies when different non-text indica¬ tors want to light up the same warning lamp. In addition to the visual display, the Check Control also uses acoustic signals. A gong or double gong are generated by the Audio System Controller (ASK). The gongs have differ¬ ent tones depending on the importance of the associated message. The gong can be gen¬ erated every time the CC message is re-displayed or only once during the initial appear¬ ance of the message The acoustic signals are output, depending on the reason for the warning, via the front left- hand and/or right-hand vehicle loudspeakers. Operation The messages of the Check Control are automatically displayed in display area 4 and 5 of the instrument cluster. If these display areas already contain data at the time a fault occurs (e.g. from the On-Board Computer), this is overwritten by the Check Control. The CC button in the turn signal stalk can be used to browse through all the CC messages issued (press briefly), or to toggle between the On- Board Computer and Check Control in the display area below the tachometer. Eight seconds after the last touch to the button, the display switches back automatically to the initial state (dark¬ ened or On-Board Computer). Darkening is not possible when a message of priority 1 is displayed in the Check Control (e.g. engine overheating), or the fuel gauge is at reserve. 28 E65 Instrument Cluster Overview of CC Messages Responsible Control Unit Priority Graphic con Check Control Message Instruction in Control Display Gong ARS P2 m Dynamic Drive Inactive “Dynamic Drive inactive!” Vehicle detects increased Body roll in curves.

Gong Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes 42 E65 Instrument Cluster On-Board Computer (BC) The On-Board Computer in the E65 is not only a trip computing system; it also provides the driver with important vehicle information. New Features The fuel tank contents, current consumption, total mileage and trip odometer, which have until now been displayed in separate, fixed-position displays in the instrument cluster, are now integral parts of the On-Board Computer. They are scrolled through as items of information and only displayed when the driver active¬ ly requests them. Only the fuel gauge is automatically displayed as soon as the reserve level is reached. Most of the data for the On-Board Computer is transferred by control units in digital form via the K-CAN System to the instrument cluster, where it is processed and displayed in the instru¬ ment cluster itself or in the Control Display (transfer to that point by MOST telegram). Coolant level, wiper fluid levels and the outside temperature are signaled to the instrument cluster by hardwire. The tank level is reported in redundant form by two independent analog direct lines to the instrument cluster. In the case of average values, only dashes are displayed until the wheel speed signal arrives. The wheel speed signals are reported by the sensor of the left-hand rear wheel via the DSC control unit per K-CAN System to the instrument cluster. If this sensor is defec¬ tive, the right-hand rear wheel is used. All texts for the On-Board Computer are stored in the Control Display. The corresponding numerical values are provided by the instrument cluster via MOST. The information mem¬ ory for consumption and travel distances is also located in the instrument cluster. 43 E65 Instrument Cluster The On-Board Computer in the Control Display is operated by means of the Controller on the center armrest. It consists of the following sub-functions: • "Main" on-board computer, referred to simply as the On-Board Computer. Its information can be called up and scrolled as in previous models by pressing the turn signal switch and viewing the display in the instrument cluster. • Travel Computer. This computer is used to monitor one or more parts of a trip; its information can only be displayed in the Control Display. • Stopwatch and limit. These can also, like the travel computer can only be displayed in the Control Display, but they can be activated directly in the main menu "On-board computer". • Setting menu for independent ventilation, clock/date and memory signal are activated using the entry "Settings" in the main menu "On-board computer". The “units” selection for the entire scope of the on-board computer are also located here. Not all functions of the On-Board Computer that are displayed in the Control Display can also be displayed in the instrument cluster; only those of the "main" On-Board Computer can do this. However, the functions of the On-Board Computer that cannot be displayed in the Control Display can only be displayed in the instrument cluster (fuel gauge, total mileage, trip dis¬ tance). 421000 44 E65 Instrument Cluster On-Board Computer 2,G 1/100 km Reset D2 frivut JJJ TMC ^ 20,0%: MAutO 192 km 10 r 0 1/100 km Auto£ 20,0% 10:55 V' in Arrival Speed Co/rsurtiptron 735 km 10:55 0 B7,6 Km/ 0 0,61/100 116.1 km/h Reset • Distance Entered manually using the controller and then computed (counted down) by the instrument cluster or transferred by the navigation system via MOST to the instrument cluster. In this case, the navigation system handles the calculation up to the position "0"; from then on (minus distance), the instrument cluster continues the count in both cases. • Range Calculated from the average fuel consumption figure and the tank contents. A calculation compensates for idle periods with the engine running or sudden changes in driving style. The average fuel consumption figure is a calculated result which, depending on the driving situation, revises the current fuel consumption over a given period. This ensures that the calculated results are plausible and that large jumps are avoided if vehicle handling changes suddenly. • Arrival time Calculated from distance, time and an average speed. Here, too, the calculation method ensures equalization of the average speed so that there are no larger jumps in time; the displayed value grows or shrinks minute by minute. The arrival time can only be calculated when the clock has been set and a distance entered. If no distance is entered manually, but is adopted from the navigation system, there is a permanent alignment with the route guidance on the basis of the roadmap data. The result is a significantly more precise prediction of the arrival time. 45 E65 Instrument Cluster • Average fuel consumption The calculation interval always begins with a manual reset; the display appears after arrival of the speed signal . The basis of the calculation is the data from the consumption and travel memory. • Average speed Here, too, each calculation interval begins with a manual reset; the display appears after arrival of the speed signal. The basis of the calculation is the data from the consumption and timer. The reset of average fuel consumption and speed is by means of the controller, directly in the menu of the on-board computer in the Control Display. When one of these displays is selected, a dialog window appears on the screen to enable a selective reset. Tap button 2 (BC) to scroll Tap button 1 (CC) to scroll 421003 46 E65 Instrument Cluster Individual items of information of the On-Board Computer can also be displayed in the instrument cluster: • Distance • Fuel gauge (tank contents can only be viewed in KOMBI) • Range -can be displayed in the display field below the speedometer, Arrival time Average fuel consumption Average speed Total mileage Distance to destination Current consumption Can only be viewed in the instrument cluster -can be displayed in the display field below the tachometer. The functions Stopwatch, Limit and Memo as well as the timer for independent ventilation are only provided in the Control Display. They cannot be displayed on the instrument clus¬ ter. When the vehicle is started, the information that was last selected will be displayed. If the display area below the tachometer contains a Check Control message, no function of the On-Board computer is displayed there. The displays of the On-Board Computer are scrolled and shown in the instrument cluster by means of buttons in the turn signal stalk. J a kt-9189 Pressing and holding the top (1) button toggles between Check Control and On-Board Computer in 12 the display area below the tachometer. Briefly tap¬ ping scrolls through its functions. Briefly tapping the lower button (2) scrolls all the dis¬ play options in the display area below the speedometer. Pressing and holding darkens both display areas. Darkening is not possible when a Check Control message is active or the fuel gauge is at reserve. A single display area cannot be dark¬ ened, the fields are always active or dark as a pair. 47 E65 Instrument Cluster Travel Computer The travel computer is used to monitor individual stages of a trip. It must be selected and activated separately in the On-Board Computer menu in the Control Display. The travel computer displays the starting time and date, driving time, distance travelled, average fuel consumption and average speed exclusively in the Control Display. The travel computer information cannot be displayed on the instrument cluster. The “START” button , selected using the controller activates the travel computer. If a trip is interrupted, the calculation of the average values is stopped as of terminal 15 Off (unless START or STOP are activated) and only continued when the trip is resumed. The “STOP” button freezes the displays. Selecting “START” again resets all the displays of the travel computer; a selective reset of an individual functions is not possible in the travel computer. 48 E65 Instrument Cluster Limit A speed limit can be entered in the On-Board Computer, and a warning is triggered when the limit is exceeded. The range above this speed is displayed with a bright bar segment within the speedome¬ ter dial in the LCD area of the speedometer. The limit can either be entered manually or the current driving speed can be adopted as the limit; both take place using the Controller and Control Display. The function is ready for operation and input as of terminal R On, but the limit warning can only be triggered during driving (terminal 15 On and incoming speed signal telegram). The instrument cluster saves the current speed limit and the corresponding activation state, even after terminal R Off. If the limit entered is exceeded, a gong sounds and a message appears in the Check Control. The information on the limit and activation state is reported by the Control Display to the instrument cluster per MOST telegram and stored in the instrument cluster. 49 E65 Instrument Cluster Stopwatch The stopwatch is ready for operation as of terminal R. 1*11 DIP) I>*r , 77.fr: 7 foec \EC [Limit 01 hlKm T.Ttf QQ.

Enter the total sum of the last 5 digits of the vehicle identification number. The total is set by pressing the trip distance reset button and displayed in the field CODE: each press of the button increases the total number by one digit. If the trip distance reset button is pressed more than 45 times, the total input number jumps back to 00. The total cannot exceed 45. 3. The input is acknowledged by pressing the trip distance reset button for longer than 2 seconds. Now, all the test functions have been enabled and can be selected using the trip distance reset button in the left-hand display area within the speedometer. The test functions remain unlocked until they are locked again using test function 19. To lock the test functions: 1. Select test function 19. The following appears in display area 2 within the tachometer: LOCK: OFF 2. When the reset button is pressed, the following appears: LOCK: ON 3. The input is acknowledged by pressing the trip distance reset button for a longer period. Now all the test functions are locked again. 62 E65 Instrument Cluster Test Function 20: Correction Factor for Average Consumption This test function must be unlocked before starting (see test function 19). This function is for checking and entering a correction factor for the fuel consumption figures. When this test function is started, the correction factor for the average consumption appears in display area 2 within the tachometer. Entry of the correction factor is only possible within the range of 750 to 1250. At produc¬ tion, the factor 1000 is stored in the EEPROM. The correction factor is reduced by a numerical value of 1 with each brief touch of the reset button. Pressing the BC button on the turn signal stalk counts down in steps of ten to shorten the time required for the resetting procedure. If the minimum value of 750 is reached, the display jumps to the maximum value 1250 and the counting resumes backwards. The input is acknowledged by pressing the reset button on the instrument cluster. The correction factor CC is calculated from the actual quantity of fuel consumed “CON ACT”, and the displayed value “CON DIS”: CC= (CON ACT./CON DIS) X 1000 1/100 km 63 E65 Instrument Cluster Test Function 21: Software Reset/RAM Reload This test function must be unlocked before starting (see test function 19). This test function triggers a software reset and/or a RAM reload of the instrument cluster processor. During the software reset, all customer-relevant displayed values from the On- Board Computer, time, date and trip distance recorder are reset. In the case of a RAM reload, the RAM is re-initialized, with the exception of the date and time. When this test function is started, the following list appears in display area 2 within the tachometer: RAM reload ? SW RESET ? The RAM reload is started by pressing the reset button for > 2 seconds. A brief tap switches to the software reset, which is then triggered by another long press on the reset button. If the test function is to be closed without triggering a RESET, the remote control must be removed or one of the two buttons (BC/CC) must be pressed on turn signal stalk. Note: A software reset should be performed after replacement of a tank lever sensor or a temperature sensor, otherwise the dampening function in the software will only display the actual current value after a considerable delay. 64 E65 Instrument Cluster Resetting Condition Based Service (CBS) Display When one or more service items have been carried out, (e.g. front and rear brake linings have been changed), these services must be reset to their full service interval. This is accomplished using the Instrument cluster. In the future, it will be possible to do this with the Diagnostic tester. • To reset a service, press the reset button on the top left part of the instrument cluster for more than ten seconds in KLR or KL15. This brings you directly to Reset mode. • A menu appears in the speedometer. At the top is the “Back” function, then the first three service items. Service item menu Reset mode for each individual service item is entered by pressing item in menu for > 2 seconds. 421004 65 E65 Instrument Cluster The residual wear or the remaining time are specified (possibly with a minus sign). The "!" symbol means that you can reset this service operation (early production vehicles may show an “F”), while a "0" indicates it is not re-settable (the first 20% of the service inter¬ val is also protected against accidental reset). You can scroll through the service items by pressing the reset button or the lower button (CC button) on the turn signal switch. When you have selected a service item, press the reset button > 2 seconds to display a 2- line menu in the tachometer. The “Back” function is at the top, the re-settable service item is below it. Now select the service item with the reset button (or the CC button) and press and hold the reset button again. In a third menu line, further down, the system confirms thaf the reset volume was suc¬ cessful. The whole interval for the service operation is shown in the “Service Need Indicator “ using the Control Display. 66 E65 Instrument Cluster Review Questions 1.
