Range, Function
The fuel tank contents and estimated range are displayed on a common mask in the multifunction display (A1p13).
Fuel tank contents, function
The fuel tank contents are displayed in liters (top figure), in US gallons (bottom figure) or in UK gallons ((FUEL TANK CONTENTS)) appears in the text displays (1) and ((RANGE)) in text displays (2).
NOTE: No special switchover between US/UK gallons is necessary. It takes place automatically via the national variant settings with the STAR diagnosis tool.
The trip computer of instrument cluster (A1) requires the following information to determine the fuel tank contents:
- Level of fuel in the tank: For this purpose, the fuel level sensor (B4) is read by the rear SAM control module (N10/8) and the corresponding message placed on the CAN interior.
- The instrument cluster (A1) receives this message, evaluates it and displays the corresponding value as the fuel tank contents.
NOTE: The fuel tank contents are displayed in steps of 1 liter or 0.2 gallons. Coding is not required for the type of fuel tank (standard tank or ski bag). This was made possible by designing the fuel tank sensor accordingly.
Range, function
The estimated range is displayed in kilometers (top figure) or miles (bottom figure).
The ratio of the fuel tank contents and average fuel consumption (((FROM STARTING))) is formed to calculate the range.
The following information is therefore required to calculate the range:
- current fuel tank contents (see above)
- average fuel consumption: The data from the short-distance memory is used (((FROM STARTING)))
NOTE: The range is displayed in steps of one kilometer or one mile. If the fuel tank level is in the reserve range, the range is updated more often. The reserve range used as a basis may differ slightly from the reserve range shown in the fuel level gauge (A1p2) of the instrument cluster (A1).

The following points are explained in this document:
- Operation of multifunction display
- Calling up the display of different systems
- Scrolling within a system
- Example: Displaying engine oil level
- Individual settings
- Changing the setting
- Example: °Changing over the temperature display from °Celsius to °Fahrenheit
- Reproducing the plant settings
- Calling up stored fault messages and warning messages
- Acknowledging fault messages and warning messages in the multifunction display (A1p13)
- Adjusting brightness of illumination
Operating the multifunction display (A1p13)
If the instrument cluster (A1) is activated, by opening the driver's door for example, the basic display of the basic system (trip odometer and total distance travelled) always appears in the multifunction display (A1p13)
Calling up the display of different systems
Functional prerequisite:
Circuit 15r: ON
The multifunction display (A1p13) is changed over to the basic display of the next system or to the ((Settings...)) function by pressing the system select pushbutton (S110s3) of the multifunction steering wheel. (The length of time the button is pressed does not matter).
Each time the button is pressed the display moves along one more system.
If all the systems have been run through, the basic display of the basic function is reached again and the sequence starts all over again.
The figure opposite shows the alternative/possible systems arranged in a circle. When the system select pushbutton (S110s3) is pressed the display moves along clockwise to the next system.
NOTE: Only systems and functions are displayed which the vehicle is equipped with. If a system is not fitted, it is ((skipped)) by pressing the system select pushbutton (S110s3).
Scrolling within a system
Functional prerequisites:
Circuit 15r: ON
Most systems have other display masks available in addition to the basic display.
The scroll forward/back pushbutton (S110s1) serves to scroll within a system.
The function of the scroll forward/back pushbutton (S110s1) is shown in the figure below using the basic system as an example. Each time the scroll forward or scroll back pushbutton (S110s1) is pressed, the display moves on.
The direction of scrolling depends on the button segment pressed (up arrow, down arrow).
NOTE: From any display mask it is possible to change over to another system by pressing the system select pushbutton (S110s3).
With the exception of the trip computer, the basic display of this system then appears.
If a change is made from the system before it to the trip computer system, the display mask last displayed for the trip computer system is always called up.
< f >Example: Engine oil level display (the ignition is switched on): < f >
- Press the system select pushbutton (S110s3) until the basic function (trip odometer, total distance travelled) is displayed
- either
- press scroll forward pushbutton (up arrow) twice or
- press scroll back pushbutton (down arrow) once
Individual settings
Functional prerequisites:
- Circuit 15r: ON
- Vehicle speed less than 5 km/h
The driver has the option of carrying out various presettings via the ((Settings...)) function.
The following settings can be performed relating to the instrument cluster (A1)
- Setting the time in hours (on vehicles without COMAND code 352 only)
- Setting the time in minutes (on vehicles without COMAND code 352 only)
- Temperature display:
The display of outside temperature can be changed over between °Celsius and °Fahrenheit. In addition the instrument cluster (A1) places a corresponding message for air conditioning on the CAN interior.
- Speedometer
It is possible to change over between miles and kilometer units. This changeover also affects the display of the trip computer integrated in the instrument cluster (A1).
In addition the instrument cluster (Al) places a corresponding message on the CAN engine compartment.
- Text/language
Here the language can be selected in which the texts are displayed in the instrument cluster (A1).
The instrument cluster (A1) also places a corresponding message on the CAN interior.
(The language setting on the COMAND system does not affect the language setting on the instrument cluster (A1)).
The following settings are also possible:
- Automatic door locking (On or Off)
- Speed limiting for winter tires (210 km/h or Off)
- Driving lights light circuit (manual, automatic, lights on permanently)
- Headlamp connection (time)
- Interior light shutoff delay (time)
- Station search (frequency/memory)
More detailed information on these settings can be found in the function descriptions for the relevant systems.
Changing the settings:
- Press system select pushbutton (S110s3) until the ((Settings...)) < f > function appears in the multifunction display (A1p13),
- Press the scroll forward pushbutton (up arrow) or scroll back pushbutton (down arrow) until the display of the setting to be changed appears in the multifunction display (A1p13).
- Press pushbutton + and -, setting of specific functions and volume control (S111s1) in the (+) or (-) direction until the arrow in the display is on the desired value.
- The setting is valid immediately.
NOTE: Settings can only be made at vehicle speeds below 5 km/h. If the speed increases to over 10 km/h during the setting the display returns to the ((Settings)) basic display. The display only switches back to the previous display mask once the speed drops below 5 km/h again.
Example:
Changing over the temperature display from °Celsius to °Fahrenheit
- Press system select pushbutton (S110s3) until the ((Settings...)) function appears in the multifunction display (A1p13).
- Press the scroll forward or scroll back push button until the ((TEMPERATURE DISPLAY)) readout appears in the multifunction display (A1p13).
