Lamps in instrument cluster

Problem - The yellow ABS malfunction

indicator lamp comes on while driving.

344

General information: If any of the following lamps in the instru- ment cluster fails to come on during the

bulb self-check when switching on the ignition, have the respective bulb checked and replaced if necessary.

Possible cause The ABS has detected a malfunction and has switched off. The BAS and the ESP are also switched off (see messages in display). The brake system is still functioning normally but without the ABS available. If the ABS control unit is malfunctioning, other systems such as the navigation system* or the automatic transmission* may also be malfunctioning.

The charging voltage has fallen below ten volts. The ABS has switched off. The battery might not be charged sufficiently.

Suggested solution 왘 Continue driving with added caution. Wheels may lock during hard braking, reducing steering capability.

왘 Read and observe messages in the

display (컄 page 352).

왘 Have the system checked at an autho- rized Mercedes-Benz Center as soon as possible.

Failure to follow these instructions increases the risk of an accident. 왘 Switch off electrical consumers that are currently not needed, e.g. seat heating*.

왘 If necessary, have the generator (alternator) and battery checked. When the voltage is above this value again, the ABS is operational again.

Vehicle status messages in the multifunction display

Warning and malfunction messages appear in the multifunction display located in the instrument cluster. Certain warning and malfunction messag- es are accompanied by an audible signal. Address these messages accordingly and follow the additional instructions given in this Operator’s Manual. Selecting the vehicle status message memory menu in the control system (컄 page 138) displays both cleared and uncleared messages. High-priority messages appear in the multifunction display in red color.

Certain messages of high priority cannot be cleared from the multifunction display using the reset button (컄 page 126) or button j, k, ÿ, or è on the steering wheel. Other messages of high priority and messages of less immediate priority can be cleared from the multifunction display using the reset button (컄 page 126) or button j, k, ÿ, or è on the steering wheel. They are then stored in the vehicle status message memory (컄 page 138). Remember that clearing a message will only make the message disappear. Clearing a message will not correct the condition that caused the message to appear.

Warning!

All categories of messages contain important information which should be taken note of and, where a malfunction is indicated, addressed as soon as possible at an authorized Mercedes-Benz Center.

Failure to repair condition noted may cause damage not covered by the Mercedes-Benz Limited Warranty, or result in property damage or personal injury.
