Operating the multifunction display (A1p13)
If the instrument cluster (A1) is activated, e.g. by opening the driver's door, the basic display of the basic function (trip distance/total distance) always appears in the multifunction display (A1p13).

Calling up display for various systems
Function condition.
Terminal 15r: ON

By pressing one of the system selection pushbuttons (S110s3) on the multifunction steering wheel, the multifunction display (A1p13) is changed over to the basic display for the next or previous system. (It makes no difference how long the button is pressed). When the inner button is pressed the display jumps to the next system and when the outer button is pressed the display jumps to the previous system in each case.
If all the systems have been run through, you will return to the basic display for the basic function and the sequence will start again.







The figure opposite shows the possible systems in a circle. When the inner system selection pushbutton (S110s3) is pressed the display jumps clockwise (arrow on right) to the next system.
When the outer system selection pushbutton (S110s3) is pressed the display jumps counterclockwise (arrow on left) to the previous system.

The basic function can also be called up from all systems by pressing the trip odometer reset button (A1s3) for 10 seconds. However, this is not possible from the setting menus.


NOTE: Only the systems and functions that the vehicle is equipped with are displayed. If a system is not fitted, it is "skipped" when one of the system selection pushbuttons (S110s3) is pressed.


Scrolling within a system
Function conditions;
Terminal 15r: ON

Apart from the basic display most systems make further display screens available.
The scroll forward/back pushbutton (S110s1) serves to scroll within a system.
The function of the scroll forward/back pushbutton is shown in the figure under the example of the basic system. The display moves on each time the scroll forward/back pushbutton (S110s1) is pressed.
The scrolling direction depends on the button sector pressed.

NOTE: It is possible to change over to another display screen from any display screen by pressing the system selection pushbutton (S110s3).







Example: Displaying remaining distance or remaining time (the ignition is switched on):
- Press a button sector for the system selection pushbutton (S110s3) until the basic function (trip distance/total distance) is displayed.
- Press the scroll forward or scroll back pushbutton until the remaining time or remaining distance appears in the multifunction display (A1p13).

Individual settings
Function conditions:
- Terminal 15r: ON
- Speed less than 5 km/h

The driver has the possibility of carrying out various pre-settings via the "Settings" function. The following settings can be carried out for the instrument cluster (A1):
- Time, setting the hours (on vehicles without COMMAND code 352 only)
- Time, setting the minutes (on vehicles without COMMAND code 352 only)
- Temperature display:
The outside temperature display can be changed over between °C and °F.
In addition the instrument cluster (A1) sends a corresponding message for the air conditioning to the CAN/interior.
- Speedometer
It is possible to change over between miles and kilometer units. This change over also acts on the trip computer display integrated in the instrument cluster (A1).
In addition the instrument cluster (A1) sends a corresponding message to the CAN engine compartment.
- Text/language
Here the language can be selected in which the texts in the instrument cluster are displayed. The instrument cluster (A1) also sends a corresponding message to the CAN (A1 - A40/3, A2).
(The language setting on the COMMAND system does not act on the language setting of the instrument cluster (A1).

In addition the following settings, are possible
- 12/24 HOUR (the time display can, be changed over from the 12 hour display to 24 hour display.)
- Speed limitation for winter tires (210 km/h, 190 km/h, 160 km/h (130 MPH, 110 MPH, 100 MPH) or Off)
- Station search (frequency/memory)

More detailed information on these settings can be found in the function descriptions for the relevant systems.







Changing the setting:
- Press the system selection pushbutton (S110s3) until the "Settings..." function appears in the multifunction display (A1p13)
- Press the scroll forward (uparrow) or back (downarrow) pushbutton until the display for the setting to be changed appears in the multifunction display (A1p13).
- Press the pushbutton + and -, setting of specific functions and volume control (S111s1) in the (+) or (-) direction until the arrow in the display is on the required value.
- The setting is valid immediately


NOTE: Settings may only be changed at speeds below 5 km/h. If speed increases to over 10 km/h during the settings, the display returns to the "Settings" basic display.


Only if speed drops to below 5 km/h again does the display switch back to the previous function.

Example:
Changing over temperature display from °C to °F
- Press the system selection pushbutton (S110s3) until the "Settings..." function appears in the multifunction display (A1p13)
- Press the scroll forward (uparrow) or back (downarrow) pushbutton until the "TEMPERATURE DISPLAY" display appears in the multifunction display (A1p13),
- Press the (-) button on the right side of the steering wheel side, the arrow in the display now points to F
- The setting is valid immediately

Reproducing plant settings
All the possible settings are erased here by a reset and the plant setting is reproduced.
Carry out reset:
- Press the system selection pushbutton (S110s3) until the "Settings..." function appears in the multifunction display (A1p13),
- Press the trip odometer reset button (A1s3) for at least 3 seconds,
- "DO YOU WANT TO RESET TO WORKSHOP SETTINGS?" appears in the multifunction display (A1p13)
- Press the reset button once more within 5 seconds, all the settings are now reset to the plant setting.
If the reset button is not pressed within 5 seconds, the display switches back to the basic display and the settings are not then reset.

Calling up stored fault and warning messages
When the instrument cluster (A1) is activated, the stored messages can be scrolled through:
- Press "Accept/terminate phone call push button" (S111s3) until the "FAULTS" display appears in the multifunction display (A1p13).
- Scroll through the fault messages with the "pushbutton and setting of specific functions and volume control" (S110s1). The messages are displayed in the sequence in which they were acknowledged.

Acknowledgement of fault and warning messages in the multifunction display (A1p13)
Most messages in the multifunction display (A1p13) can be acknowledged by pressing the trip odometer reset button (A1s3) or one of the steering wheel buttons. Indicator or warning lamps which come on in parallel cannot be acknowledged.

Setting brightness of the illumination
The brightness of the illumination of the instrument cluster (A1) and the search and switch illumination can be set to individual requirements using the instrument and search illumination pushbutton, bright (A1s4) and instrument and search illumination pushbutton, dark (A1s5):
- The instrument and search illumination can be set from minimum to maximum within 4 seconds by pressing the instrument and search illumination pushbutton, bright (A1s4) continuously.
