Lamps in instrument cluster
General information:

light up during the bulb self-check when 
turning the key in steering lock to 
position 2, have it checked and replaced if 
necessary.
Problem
Possible cause
Suggested solution
-
The yellow ABS warning lamp 
comes on while driving.
ABS has detected a malfunction and has 
switched off. The BAS, ESP, 4-ETS and EBP 
are also switched off.
The brake system is still functioning normally 
but without 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 Light Truck Cen-
ter as soon as possible.
Failure to follow these instructions in-
creases the risk of an accident.
The charging voltage has fallen below 
10 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 the battery checked.
