There are slight differences which can be distinguished by the gauge configurations. The E63/E64 instrument cluster uses a speedometer which has a slightly finer scale and there is an oil temperature gauge located below the tachometer. The E60 and future E61 uses the more familiarfuel consumption indicator in the tachometer area. Both clusters use the new annular indicators. Forthe first time, this type of gauge display is used by BMW forthe two main instruments .This represents an innovation in display technology. This system has enabled the displays forthe cruise control system set speed and the variable engine speed warning zone to be visually illustrated. The indicator lamp forthe fuel reserve has been replaced by a Check Control message in text and graphics. Likewise, the Check Control texts are no longer displayed in the instru¬ ment cluster but in the status bar of the Central Information Display (CID). Two large instrument dials show vehicle speed and engine speed. The scales on the instrument cluster are specific to each country, vehicle and engine. Most of the indicator lamps are located in the center at the top between the two large instrument dials. Also in the center between the two large instrument dials are the two LC Displays. 4 E6x Driver Information Systems Instrument Cluster System Overview (IPO) 02266,02 5 E6x Driver Information Systems Legend for System Overview Index Explanation Index Explanation i—l Ambient temperature sensor 11 M-ASK orCCC 2 Coolant level switch 12 Central Information Display (CD) 3 Fuel level sensor, left 13 D IS plus/GT-1 4 Parking brake warning switch 14 Safety and Gateway Module (SGM) 5 Fuel level sensor, right 15 Brake pad wear sensors 6 Windshield washerfluid level sensor 16 Electronic Transmission Control Module (EGS) 7 Front power distribution box 17 Dynamic Stability Control M odule (DSC) 8 Instrument cluster (kombi) 18 Active Cruise Control (ACC) 9 Car Access System (CAS) 19 Digital Motor Electronics (DM E or ECM) 10 IHKA 20 Active Front Steering Module (AFS) Cluster Inputs and Interfaces The instrument cluster receives input signals from the following components: AmbientTemperature Sensor The ambient temperature sensorsupplies the value forthe temperature outside the vehicle to the instrument cluster. The ambient temperature is shown on the LCD display. Instrument resolution is 0.5°C (1°F). The value for ambient temperature is also made available to other control units via the K-C AN. Note: Ifthe ambient temperature sensor circuit fails, the display will show +50 degrees Celsius ifthe circuit is shorted and -50 degrees Celsius ifthe circuit is open. Fuel Level Sensors, Leftand Right The fuel tank contains two fuel-level sensors. Each fuel-level sensor sends a signal indi¬ cating the amount of fuel in the tank. A value is obtained by adding the two signals. Coolant Level Switch The coolant-level switch sends a signal ifthe coolant level is too low (Reed contact). The information is output on the LCD display in the form of a Check-Control message. Windshield WasherFluid Level Switch The Windshield washerfluid level switch sends a signal ifthe fluid level is too low. The information is output on the LCD display in the form of a Check-Control message. Parking Brake Warning Switch The parking brake warning switch indicates that the handbrake is applied. The general brake warning lamp lights up red when the handbrake is applied. 6 E6x Driver Information Systems Reset Button The reset button is used forthe following functions: • Reset trip meter • Call up Condition Based Service (CBS) • Call upTestfunctions (only for service staff) Axial buttons in turn-signal/main-beam switch The axial buttons (Check-Control button at top, on-board computer button at bottom) are forthe following functions: • Menu of the Check-Control system in the LCD display and clock/date selection • Menu of the on-board computer in the LCD display The signal generated when one of the axial buttons is pressed is transmitted through the bus system. Bus Interfaces The following control units communicate via the PT-CAN orthe K-CAN with the control unit of the instrument cluster: Dynamic Stability Control An active regulation sequence ora fault in the DSC will be indicated by the correspond¬ ing indicator and warning light (ABS, DSC orDTC). The brake pad wear sensors are also connected to the DSC control unit. The general brake warning light is actuated if the brake pads wearto the permissible limit. Front and rear brake pad wear is a CBS service operation (sensor-based). Active C ruise C ontrol There are now a permanent indicator and warning lights in the instrument clusterfor Active Cruise Control (ACC). They indicate: Object detected or driver override, distance levels 1 to 4. Active Front Steering A fault in the active front steering system is indicated by the corresponding indicator and warning light being actuated. Digital Motor Electronics The appropriate indicator and warning light is activated to indicate a fault in the DM E. Engine oil is a CBS service operation (sensor-based). 7 E6x Driver Information Systems Electronic Transmission Control The EGS control unit supplies the signal forthe gear engaged to the instrument cluster. The selected gear is shown in the selector-lever and shift indicator in the LCD display. Safety and Gateway Module The appropriate indicator and warning light is activated to indicate a fault in the passive safety system (airbag). The SGM is the gateway between the byteflight, PT-CAN and K-CAN data buses. The diagnosis lead is also connected at the SGM. Light Module A fault in the lighting system is indicated by the light module (LM) actuating the corre¬ sponding indicator and warning light. Integrated automatic heating and air-conditioning system The IHKA calculates the condition of the microfilter. The condition of the microfilter is CBS service operation. Car Access System The CAS control unit serves for redundant data storage. The following are stored in the CAS control unit (redundantly to the instrument cluster): • Vehicle identification number • Odometer reading • CBS data M-ASK/CCC andCID Forthe instrument cluster, the M-ASK and CCC serve as an interface to the Central Information Display (CID).The CID displays detailed texts concerning Check-Control messages and information about CBS and other on-board computerfunctions.The CID also enables the driverto change the units of measurement (e.g. Celsius to Fahrenheit, and vice versa) forthe instrument cluster. Moreover, the M-ASK and CCC establish a telephone connection when a CBS serve operation is due (=TeleService).This is achieved by sending a message to the telephone control unit via the M OST. Other control units communicate via the bus to send messages (Check-Control mes¬ sages) to the instrument cluster. The instrument cluster emits these Check-Control mes¬ sages via symbols in the LCD display. 8 E6x Driver Information Systems Components The instrument cluster comprises the following components: • Instrument dials • Indicator and warning lamps • LC display • Program and geardisplays forautomatic gearbox and SMG Sequential Manual Gearbox • Setting button for resetting the trip meter and operating the Condition Based Service,CBS menu • Connected components which serve to activate the displays in the instrument cluster Display Areas The instrument cluster is divided into the following display areas: • Instrument dials (Analog Instruments) • Indicator and warning lamps • LC display • Program and geardisplays forautomatic gearbox and SMG Sequential Manual Gearbox Index Explanation Index Explanation 1 Set speed for cruise control 4 Tachometer warning zone 2 Speedometer 5 Fuel gauge 3 Tachometer 6 Fuel consumption indicator 9 E6x Driver Information Systems Analog instruments and moving-disc indicators The instrument cluster has a total of 6 stepper motors forthe various instruments. Forthe first time, moving-disc instruments are used in the instrument cluster. 0 n the left, the set speed for cruise control is displayed on a moving-disc instrument. On the right, a moving-disc instrument shows the engine-revolutions advance-warning field. The engine-revolutions advance-warning field is subdivided into: • Fixed engine-revolutions advance-warning field • Variable engine-revolutions advance-warning field The maximum engine speed warning display is indicated by the tachometer as a function of engine temperature. 1.

The annular indicator is moved by means of the ring gear, connected to the indicator, the pinion and the stepper motor which is attached to the rear of the light duct. U.S. vehicles will have speedometers with 0-160 M PH and 0-7000 RPM displays. 11 E6x Driver Information Systems Indicators and Warning Lamps The indicator and warning lamps are activated by the processor in the instrument cluster. The main indicator and warning lamps are activated in the Pre-drive Check when terminal 15 is switched on. The indicator lamps and warning symbols are lit by soldered-in LEDs (replacement of LEDs not possible). 1. Left turn signal indicator 2. Indicator lamp area 3. Rightturn signal indicator LC Display The LC display is located between the speedometer and the rev counter. The LC display is divided into two areas. The time and outside temperature are displayed in the upper window, along with the set speed forthe ACC, check control messages and CBS dis¬ plays. The on-board computerfunctions, trip distance counter and CBS messages are output to the lower window. A manipulation dot indicates if there are different vehicle identifica¬ tion numbers in the light module and in the instrument cluster. i) 1. Upper LCD display area 2. Lower LCD display area 3. Trip counter reset button 12 E6x Driver Information Systems Program and Gear Display On vehicles with automatic transmission orsequential manual transmission (SM G), the program and gear selected are shown in the center ofthe lower window ofthe LC display. The program and gear display is activated when terminal 15 is on. At terminal 15 off, run-on operation ofthe display is possible provided the SM G is still transmitting CAN messages. The information between the control units forthe automatic gearbox or SMG and the instrument cluster are exchanged via the K-CAN. The program and gear display shows letters and numbers. The program mode is displayed all the time and is not overwritten by other information. 1] 2 02521_02 Note: With SMG, the selector-lever position "N" flashes afterthe engine is turned off. This indication serves as a visual reminder that the car could still roll away. 13 E6x Driver Information Systems Principle of Operation The control unit of the instrument cluster incorporates certain functions over and above the display and indication functions, namely: • Lighting of the instrument cluster • Dimming of the instrument cluster • High and low-voltage detection forthe instrument cluster • Heating and contrast for the LCD display • On-board computerfunctions • Check-Control messages • Pre-drive check • Condition Based Service (CBS) • Vehicle identification check Lighting of the Instrument Cluster The instrument cluster has an integral power supply unit. The power supply is connected to terminal 30. The power supply provides the supply voltage forthe instrument cluster. This arrangement means that the lighting of the instrument cluster is independent of the on-board power supply. If the on-board power supply is disrupted (voltage dips), the brightness cannot fluctuate. LEDs in BMW orange provide backlighting forthe LCD display, the pointers of the analog instruments and the scale rings. The pointers and the scale rings are illuminated when the lights are switched ON (=function display). The display itself is not back-lit unless it contains a reading. Acoustic Generator Acoustic warnings are issued in support of the Check-Control messages. The instrument cluster controls these warnings by means ofthe K-CAN.The M-ASK and CCC emit acoustic warnings through the loudspeakers. An additional loudspeaker in the instrument cluster issues the following acoustic warnings: • Flash • Hazard warning lights 14 E6x Driver Information Systems Dimming of the instrument cluster The brightness of the LCD display and all indicator and warning lights is adapted to suit ambient lighting conditions. This function is implemented by a phototransistor in the instrument cluster. The brightness signal is calculated in the instrument cluster on the basis of the following values: • Signal from the phototransistor (ambient luminosity) • Dimmer signal (on the control panel forthe lights) The brightness signal calculated in this way is made available to the other control units via the K-CAN. High and low-voltage detection forthe instrument cluster If the on-board voltage drops below approximately 7.5 volts, no further read or write accesses to the data memory are permitted. The instrument cluster initiates data backup in advance of a pending reset triggered by undervoltage. Overvoltage in the on-board power supply is also detected. If the on-board voltage is greater than 16 volts: • Certain inputs and outputs are disabled in orderto protect the hardware. • Indicator and warning lights are dimmed forthe duration of the overvoltage or are deactivated in orderto prevent overload. Heating and contrast forthe LC D display A heater built into the display ensures good legibility even at low ambient temperatures. The heater is switched on if the temperature of the LCD display is below 10 °Celsius. The switch-on signal is transmitted (by the CAS control unit to the instrument cluster via the K-CAN) when the driver's door is opened. The contrast of the LCD display is automatically set as a function of the temperature of the LCD display and the operating time. A counter registers the standby times and oper¬ ating times logged by the instrument cluster, so that due allowance can be made for age¬ ing. Contrast voltage is automatically adjusted depending on increasing time in operation (ageing). 15 E6x Driver Information Systems On-board Computer Functions There are two ways in which on-board computerfunctions can be displayed: • in the instrument cluster • in the Central Information Display (extended on-board computerfunctions) The on-board computerfunctions forthe instrument cluster are as follows: • Ambient temperature • Time • Date • Average consumption (resettable) • Range • Average speed (resettable) The on-board computerfunction required can be displayed: When terminal R is ON by pressing the on-board computer button on the turn-signal/main-beam switch in a specific sequence. The last line is followed by an empty line, before the first line reappears on the screen (rolling list). When terminal R switches ON, the on-board computerfunction most recently selected by means of the on-board computer button reappears. If the on-board computer button is pressed and held down for longerthan 2 seconds, the values of the resettable on-board computerfunctions are recalculated. Check-Control Messages The Check-Contra I system informs the driver if important functions, information or warn¬ ings are no longer available. Check-Control messages are displayed in the form of a sym¬ bol on the LCD display (red, yellow, orange). The instrument cluster discharges the func¬ tions of priority control forthe Check-Control messages.The readings fortime and date and ambient temperature are overwritten. If a Check-Control message is present but not displayed, this will be indicated by warning triangle in the LCD display. Supplementary notes and instructions are available for most Check-Control messages and are displayed in the Central Information Display (CID) (short form can be found in the status bar). In addition to the visual display, the Check-Control system also alerts the driver with acoustic signals. Depending on the importance of the associated message, a single or double gong with varying volume and tone will sound. Current Check-Control messages can be called up with the Check-Control button (press and hold for longerthan 2 seconds) on the turn-signal/main-beam switch.The Check- Control messages can then be viewed in sequence (press for less than 2 seconds). When the Check-Control button is pressed, this is registered via the K-CAN. If 8 seconds pass without a button being pressed, eitherthe time and ambient tempera¬ ture ora current Check-Control message with priority 1 will appear. 16 E6x Driver Information Systems Pre-drive Check The pre-drive check serves as: • A check of internal functions in the instrument cluster • Monitoring of the live signals from all control units that may emit Check-Control mes¬ sages During the pre-drive check, the most important indicator and warning lights are activated for 4 seconds when terminal 15 is switched ON. Exception: Indicator and warning lights for airbags actuated when terminal R is switched ON. The following indicator and warning lights are activated in the pre-drive check: • Seat-belt warning • Airbag (initially yellow, then red) • Anti-lock brake system (ABS) • General brake warning light (initially yellow, then red) • Emission warning lamp • Dynamic Stability Control (DSC) • Active Front Steering • ACC control by driver or object detected (initially yellow, then red) Once a pre-drive check completes successfully, all indicator and warning lights are switched off. If a fault occurs during the pre-drive check, the check is interrupted for the system in question. The indicator and warning lights forthis system remain on. The Check-Control system issues the appropriate message. 17 E6x Driver Information Systems Service Notes Redundant Data Storage If the instrument cluster is exchanged, the stored data (e.g. total distance reading) must be retained. This will make it possible to detect any evidence of manipulation. In orderto guard against manipulation, the following data are stored redundantly (second copy) in the CAS control unit: • Vehicle identification number • Total distance reading (kilometer reading) • Data related to the scopes ofthe Condition Based Service The data is verified each time terminal 15 is switched on. A manipulation dot is shown in the LCD display in the event of any discrepancy. The manipulation dot appears to the left ofthe trip distance recorder. The manipulation dot is displayed in the following cases: • The vehicle identification number stored in the instrument cluster is different to the one stored in the CAS control unit. • A vehicle identification number is not stored in one ofthe two control units (e.g. new component). • The module in the instrument clusterfor storing the total distance reading is faulty (the kilometer reading is shown as 999999). Installing a new CAS control unit • Orderthe new CAS control unitforthe specific vehicle in question, quoting key number, VIN, standard equipment. • Once the new CAS control unit has been encoded (DM E/DDE control unit and CAS control unit mutually identified and calibrated), the engine can be started. Important: Do not install a used CAS control unit. The engine cannot be started if the CAS control unit being fitted has already been used (different vehicle identification number). 18 E6x Driver Information Systems Installing a new instrument cluster • The manipulation dot is displayed when terminal 15 is activated because the instrument cluster has not yet been encoded with the vehicle identification number. • Encode the instrument cluster (input the vehicle identification number in the instrument cluster and assign it to the vehicle). • Switch terminal 15 off and on. Afterterminal 15 has been switched back on: The current kilometer reading and the CBS data are transmitted to the instrument cluster by the CAS control unit. The manipulation dot disappears. Test installation of a new instrument cluster The VINs in the instrument cluster and CAS control unit do not match orthe VIN has not yet been entered in the instrument cluster. A bidirectional communication between the instrument cluster and the CAS control unit takes place as follows: • The kilometer reading stored in the CAS control unit, for example, is transferred to the working memory of the total distance recorder in the instrument cluster and then displayed. During a test drive, the kilometers covered continue to be metered in the working memory of the total distance recorder and are sent to the CAS control unit every 10 km. • If at least 24 hours have elapsed between terminal 15 being switched off and on, calibration will be repeatedly automatically regardless of the distance covered. • When the instrument cluster is removed following a test drive the working memory loses the kilometer reading stored. The instrument cluster is reset to the initial status. Important: An instrument cluster that has previously been used will not be reset. The vehicle identification number entered in a used instrument cluster can be overwritten until a distance of 254 km has been covered. It is then impossible to reset the perma¬ nently stored value. Simultaneous replacement of CAS control unit and instrument cluster Important: Do not replace the CAS control unit and the instrument cluster at the same time. Avoid simultaneous exchange of the CAS control unit and instrument cluster due to the risk of the current kilometer reading and all CBS data being irrevocably lost. 19 E6x Driver Information Systems Follow the steps below if it is necessary to replace both control units at the same time (e.g. neither respond to the BMW diagnosis system): • Replace the instrument cluster • Encode the VIN in the instrument cluster • Switch terminal 15 OFF,then ON.There may actually be a transfer of data between the CAS control unit and the instrument cluster. • Replace the CAS control unit • Encode the VIN in the CAS control unit • Switch terminal 15 off then on again. • The manipulation dot is cleared afterthe terminal 15 is switched back on. Communication between the instrument cluster and CAS control unit for redundant data storage is now ensured. Instrument C luster Test Functions The testfunctions are useful fortroubleshooting with the BMW diagnosis system. The test-function readings are displayed in the upper zone of the LCD display. The texts for the testfunctions are stored in the German-language version only. With terminal R ON orterminal 15 ON: Press the reset button in the instrument clusterfor 10 seconds to reset the testfunctions. The testfunctions can be scrolled through with the reset button in the instrument cluster. An alternative means of accessing the testfunctions is: hold down the reset button in the instrument cluster and simultaneously switch terminal RON. Note: Disabling and enabling the testfunctions Only the first two testfunctions are freely accessible. The testfunctions are disabled from No. 3 onward. They can be enabled only in test function No. 19. The testfunctions are enabled by: entering the sum obtained by adding togetherthe last five digits of the VIN. Note: For detailed list of Test Functions, access the latest SBT in WebTIS. 20 E6x Driver Information Systems Condition Based Service (CBS) With the series launch of the new 5 Series, BMW will also be offering service intervals that are geared towards the current condition of selected critical components - i.e. servic¬ ing that depends on the condition of components and maintenance requirements; this is known as Condition Based Service (CBS). CBS means thus: maintenance onlyforthe component which is worn. The system calculates when a service operation, e.g. an oil change or emissions inspec¬ tion, is due and informs the customer of this via the LC display in the instrument cluster. CBS sorts all the data according to date due and can determine when the vehicle should betaken into BMW Service. The instrument clustersends the sorted data to the Central Information Display (CID). There, the data can be selected for display in the Service menu. There are ten different types of service, with each of these types being assigned to a specific service group. The system involves the following components: • Instrument cluster • External units (DME, IHKA, DSC) • Car Access System (CAS) 2 • Central Information Display (CID) All information that the CBS system requires is sent on the K-CAN bus. The instrument cluster is a subscriber on the K-CAN and acts as the CBS master control unit. The CBS requests from all the control units are therefore sent via the K-CAN to the instrument cluster and to the Central Information Display. 21 E6x Driver Information Systems CBS Displays Displays in the Instrument Cluster The CBS display always comprises the following two separate displays: • A colored symbol in the upper display -Orange for normal -Yellow for service due -Red for service overdue • And information on remaining distance and/or due date in the lower display.

The CBS functions are stored in the "Settings" menu item which is used exclusively for individual user settings. Press the Controller, the "Settings" menu will appear. Turn the controller until "Service" is highlighted, then press to activate the CBS menu. The CBS menu window will appear; this is divided into the following control and display fields: • Status bar • First menu bar • Second menu bar • Display field for CBS symbol • Display field for service operation 1 )— V_y = < Service-Bedarf ► 2 )— ^ « Status ► A Bremsbelage vo. 3 )— v_y - (®) km -100 A § Fahrzeugprufung A § Abgasprufung — A Bremsbelage hi.

The displays are color-coded and some also have a symbol. The displays mean the fol¬ lowing: • Red - The service operation is overdue • Yellow - The service operation is due shortly • Green - No service operation required Any overdue service operations and symbols marked in red in the list are always at the top of the list of messages. You can scroll through the list of the service operations from top to bottom by turning the controller (left/right). To display the information concerning a specific service operation on the C ID, turn the controllerto select the required service operation and display the selection by pressing the controller. Note: All screen shots shown are derived from a simulation of a version with featuring a 6.5" medium-resolution color LC display and correspond to the status at the time of going to press. Further changes are possible to the contents and the layout. 24 E6x Driver Information Systems Resetting the Service Operations When one or more operations have been carried out, e.g. front pads have been changed, these operations must be reset to theirfull service interval. There are two options for resetting the service operations: • Legally required service operations - Legally required service operations such as the Statutory vehicle inspection (HU) and the Statutory exhaust test (AU), can only be reset in the "Service" menu. • M aintenance service operations - All service operations forthe purpose of mainte¬ nance are reset by means of the reset button of the trip distance counter in the instrument cluster. If the reset button is pressed for longerthan ten seconds, the reset mode opens automatically. "Reset?" is displayed in the lower display window. In the upper display window, the CBS symbol, e.g. for "engine oil service overdue" will be displayed. Press the reset button until the time/distance-dependent displays in the lower display window are replaced with dashes. Reset is no longer possible once more than 80 percent of the interval has expired. A reset lock will be shown in the display with "OK". 1. Reset Button for trip counter 2. Upper display window (CBS) 3. Lower window display Diagnostics There are three possible combinations for replacing the instrument clusters and Car Access System. • Instrument cluster faulty, Car Access System OK • Car Access System faulty, instrument cluster OK • Car Access System and instrument cluster must be replaced. Simultaneous replacement of the Car Access System and the instrument cluster must be avoided. The odometer reading will be lost as a result. In principle it is also possible to carry out a trial replacement of the instrument cluster/Car Access System. 25 E6x Driver Information Systems Central Information Display (C ID) The Central Information Display is an integrated display and operating panel forthe fol¬ lowing functions: • Audio systems such as radio, CD, MC • Computer, journey computer • Check Control messages • Navigation • Needs-based service (BOS) • Vehicle info • Brief info • Telephone and data services • CD-ROM orDVD • Personalized functions such as station selection • Heating and air conditioning system • Vehicle functions such as DSC, EDC, PDC, RDC • Service mode 26 E6x Driver Information Systems New Features The C ID of the E60 has new features or modified features: • M ain M enu reduced to four selections - Communication - Car Data (unless equipped with Navigation) - Entertainment -Climate Control • User settings available in an additional menu setting • Two variants of controller • New M enu button • Voice Input button on center console Bus Network The M-ASK generates the LVDS data (Low Voltage Differential Signaling)forthe graphic display in the Central Information Display. The central operating control forthe Central Information Display is the controller. The controller is connected to the CID via the center console control center (SZM) and the K- CAN system. The Safety and Gateway Module (SGM) provides the diagnostics interface forthe CID via the diagnostics bus. D-Bus 27 E6x Driver Information Systems Components The Central Information Display (CID) is comprised of the following components: • Casing with integral electronic module • LC display • Casing attachment (tube) with cover glass • Controller, a connected component which controls the displays in the CID. 1. Casing with electronics 2. LC Display 3. Casing with glass LC Display In orderto cope with the various equipment specifications, the following variants are used forthe E60: • CID with 6.5" medium-resolution color LCD (400 x240 pixels) • CID with 8.8" high-resolution color LCD (640 x240 pixels) The LCD also features a help window.The casing is designed to be able to accommo¬ date all screen variants offered. The entire Central Information Display assembly is fixed to the dashboard by two screws. 28 E6x Driver Information Systems Controller The controller is the central operating control for all comfort functions and selected options for some vehicle functions that are displayed on the Central Information Display. The controller is located in the center console immediately behind the gear selector lever, within reach of the user (driver and front passenger). Forthe firsttime, the controller will be available in the following two variants forthe E60: • Variant A - The base variant has a mechanical latch system with 24 latches perfull turn. • Variant B - On the high-end version, the tactile feedback forthe rotational movement of the controller is generated electrically. The tactile feedback forthe rest position, the main directions of movement and the depressed position is created by mechani¬ cal means. The operating principle of the controller is identical with that of the E65. The controller is slid from a rest position (center position) to which it always returns again when it is released. 29 E6x Driver Information Systems The main features of the operating principle are: • The center is the rest position (center position) • S lide to select the four main directions of movement • Turn to select the function • Press to select or confirm entry. There is also a panel of buttons immediately behind the controller. There are two variants, as follows: • Basic variant - This version comprises a menu button which is used to call up the main menu in the Central Information Display. • High-end variant - This version has two buttons. In addition to the menu button, there is a button for activating/deactivating the voice input system (SVS). The button signals are read into the controller and converted into K-CAN telegrams. The four menu items are displayed in a cross pattern on the Central Information Display corresponding to the four main directions in which the controller can be moved. In addition to these four main menu items, there is a fifth menu item used exclusively for individual user settings. The screen can also be switched on and off from this menu. 30 E6x Driver Information Systems Status Bar The status bar displays the main information on the various functions, such as the telephone signal strength orthe time; this information is permanently displayed after Ignition ON.
