Lamps in instrument cluster
General information:
If a bulb in the instrument cluster fails to

Problem
Possible cause
Suggested solution
-
The yellow ABS malfunction 
indicator lamp comes on while 
driving.
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.
Continue driving with added caution. 
Wheels may lock during hard braking, 
reducing steering capability. 
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.
Read and observe messages in the 
display (
page 280).
The charging voltage has fallen below ten 
volts. The ABS has switched off.
When the voltage is above this value 
again, the ABS is operational again.
If necessary, have the generator 
(alternator) and battery checked.
