32 System functions Using a jack (service mode) There is no automatic recognition. Adaptive air suspension must be deactivated if a jack is to be used. This is done by actuating the MMI control knob in the CAR -> SETUP menu. This mode is deactivated either by resetting in MMI or by driving at a speed of >9 mph (15 km/h). Trailer mode Address book Manual adaptive air suspension Trailer mode Jacking mode Address book Manual Setup Car TP TMC Intercom adaptive air suspension Trailer mode TP TMC Intercom off off Settings Tone 292_036 Trailer mode is recognised automatically when the trailer is electrically connected to the towing vehicle. The system status (trailer mode on or off) can be requested by means of the SETUP button and activated if necessary using the MMI control knob. In the standard running gear, "dynamic" mode cannot be selected in trailer mode. Jacking mode Setup Car off off Settings Tone 292_035
Extreme low level Extreme low level (65 mm or more below normal level) is shown by the low level indicator lamp and the warning lamp flashing. Extreme low level can occur after the vehicle has been at a standstill for a very long period. Extreme high level Extreme high level (50 mm or more above normal level) is shown by the warning lamp flashing. Extreme high level may occur briefly when heavy objects are unloaded. Emergency running function If a failure of system components or signals is detected, the full functional reliability of the system is generally no longer guaranteed. Therefore, depending on the severity of the fault, an emergency running program is started. Faults are stored in the fault memory. The warning lamp in the dash panel insert comes on. 292_045 292_046 The premise for emergency running mode is the maintenance of driving stability. Excessively soft suspension is prevented. In the event of complete failure of the system control, the damper actuation is de-energized and the system is set to hard suspension.
