If the instrument cluster (A1) is activated, e.g. by opening the driver's door, the basic display of the basic function (trip and total mileage) always appears in the multifunction display (A1p13).
Calling up display of different Systems
Function prerequisites:
Terminal 15R: ON
By pressing one of the system select push-button (S110s3) on the multifunction steering wheel the multifunction display (A1p13) is switched to the basic display of the next or previous system.
The duration of actuation is of no importance. Pressing the upper button causes the display to change to the next system. Pressing the lower button causes the display to change to the previous system.
After running through all the systems, the display returns to the main screen of the basic function and then begins running through the systems again from the beginning.
The accompanying illustration shows the possible Systems arranged in a circle.
When the upper system select pushbutton (S110s3) is pressed, the display jumps clockwise (right arrow) to the next system. When the lower system select pushbutton (S110s3) is pressed, the display jumps counterclockwise (left arrow) to the previous system.
NOTE: Only systems and functions with which the vehicle is equipped are displayed If a system is not present, it will be skipped when the system select pushbutton (S110s3) is pressed.
Browsing within a system
Function prerequisites:
Terminal 15R: ON
In addition to the main screen, most Systems also feature other screens.
The scroll forward/back pushbutton (S110s1) is used for browsing within a system.
The function of the scroll forward/back pushbutton is shown in the illustration below taking the basic system as an example. On each press of the scroll forward/back pushbutton (S110s1), the display changes. The direction of browsing depends on which segment of the button (up arrow, down arrow) is pressed.
NOTE: The driver can jump to another system from any screen by pressing the system select pushbutton (S110s3).
Displaying remaining mileage or remaining time (with ignition on). Example:
- Press a segment of the system select pushbutton (S110s3) repeatedly until the basic function (trip and total mileage) is displayed
- Press the scroll forward up arrow or scroll back down arrow pushbutton repeatedly until the remaining time or remaining mileage appears in the multifunction display (A1p13).
Individual settings (second level)
Function prerequisites:
- Terminal 15R: ON
- Up to 31.05.01 vehicle speed less than 5 km/h
- As of 01.06.01 (except (GB)) also possible when driving
The driver can select the possible presets using the "Settings..." function. The following settings can be made on the instrument cluster (A1):
Set time (hours)
- Only on vehicles without COMMAND code 352
Set time (minutes)

Temperature indicator
- The outside temperature can be changed from °Celsius to °Fahrenheit and vice versa. The instrument cluster (A1) also sends a message for the air conditioning on the passenger compartment CAN.
Speedometer (can only be changed when stationary)
- This can be switched between miles and kilometers This changeover also affects the display of the trip computer integrated into the instrument cluster (A1). The instrument cluster (A1) also sends an appropriate message on the engine compartment CAN.
Text/language
- This selects the language for the text displayed in the instrument cluster (A1). The instrument cluster (A1) also sends an appropriate message on the passenger compartment CAN.
NOTE: As of 01.06.01 there are two English-language versions available (GB) and (USA). The language setting on the COMMAND system has no effect on the language setting in the instrument cluster (A1).

More information about these settings can be found in the function descriptions for the associated systems.
Changing the settings:
- Press the system select pushbutton (S110s3) repeatedly until the "Settings..." function appears in the multifunction display (A1p13)
- Press the scroll forward up arrow or scroll back pushbutton down arrow repeatedly until the display for the setting to be changed appears in the multifunction display (A1p13)
- Press the + and - button for 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 becomes effective immediately.
NOTE: Up to 31.05.01: Settings can only be made at speeds below 5 km/h. If the vehicle speed rises above 10 km/h while settings are being made, the display changes back to the screen. The display only switches back to the previous display screen when the speed falls below 5 km/h again.
NOTE: As of 01.06.01 (except (GB)): Settings can also be made at speeds above 5 km/h.
With the exception of:
- Driving lamps
Example:
Change temperature display from °Celsius to °Fahrenheit.
- Press the system select pushbutton (S110s3) repeatedly until the "Settings.." function appears in the multifunction display (A1p13)
- Press the scroll forward (up arrow) or scroll back (down arrow) pushbutton repeatedly until "TEMPERATURE DISPLAY" appears in the multifunction display (A1p13)
- Press the (-) button on the right-hand side of the steering wheel; the arrow in the display now points to °F
- The setting becomes effective immediately.
Recalling the factory settings
This procedure resets all the settings that can be made here to the factory settings:
- Press the system select pushbutton (S110s3) repeatedly until the "Settings..." function appears in the multifunction display (A1p13)
- Press the reset button (A1s3) for at least 3 seconds
- The multifunction display (A1p13) shows the message: "DO YOU WANT TO RESET TO THE FACTORY SETTINGS?"
- Press the reset button (A1s3) a second time within 5 seconds to reset all the settings to the default factory settings.
- If the reset button (A1s3) is not pressed within this 5 second period, the display switches back to the basic screen. The settings are not then reset.
NOTE: As of 01.06.01 (except (GB)) If the factory settings are restored while the vehicle is moving, the message "NOT FULLY RESET TO FACTORY SETTINGS WHILE DRIVING" appears for the subjects Station Wagon, Lights and Vehicle. When resetting from a configuration screen, the display switches back to the basic screen for the configuration.
Calling up stored fault and warning messages
When the instrument cluster (A1) is active, you can scroll through the stored messages.
- Press the "System select and voice control system" pushbutton (S111s3) repeatedly until "- FAULTS" appears in the multifunction display (A1p13).
- Scroll through the fault messages using the scroll forward/back button (S110s1). The messages are displayed in the order in which they were acknowledged.
Acknowledging fault and warning messages in the multifunction display (A1p13)
Most of the messages in the multifunction display (A1p13) can be acknowledged by pressing the trip odometer reset button (A1s3). Fault or warning lamps that light up in parallel cannot be acknowledged.
Modification as of 01.06.01
Warning messages in taxi vehicles (terminal 30) are displayed and can be acknowledged once per test cycle for 2 minutes.
Adjusting brightness of illumination
The brightness of illumination of the instrument cluster (A1) and the pushbutton unit and switch lighting can be adapted to individual requirements with the instrument illumination rheostat (A1r1):
- Clockwise rotation of the instrument illumination rheostat (A1r1) increases the brightness, counterclockwise rotation decreases the brightness.
Setting workshop level
- Terminal 15R: ON
- Select basic function
- Hold down reset button for approx. 20 seconds until the chime sounds
- Press tower system select pushbutton (S110s3)
- Hold down reset button for approx. 20 seconds until the chime sounds
- Press lower system select pushbutton (S110s3)
- The multifunction display shows, among other things, the engine type and the oil level.
To exit the workshop level, switch off terminal 15R.
Switching on ESP roller test
In the roller test, the rotational speeds of the driven axle are mirrored on the non-driven axle. To do this:
- Set workshop level (see above)
- Press scroll forward/back pushbutton (S110s1) once in the (up arrow) direction The roller test display appears
- Activate the roller test using the + and - button for setting specific functions and volume control (S111s1).
The roller test remains active, even if terminal 15R is switched off in the meantime, until it is deactivated using the + and - button for setting specific functions and volume control (S111s1).
