Problem
Possible cause/consequence
Suggested solution
-
The yellow ABS indicator lamp 
comes on while the engine is 
running.
ABS has detected a malfunction and has 
switched off. The BAS, ESP
®
, EBP, and 4-ETS 
are also switched off (see messages in multi-
function 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.
Continue driving with added caution. 
Wheels may lock during hard braking, 
reducing steering capability.
Read and observe messages in the 
multifunction display (
Have the system checked at an 
authorized Mercedes-Benz Light 
Truck Center as soon as possible.
Failure to follow these instructions 
increases the risk of an accident.
The charging voltage has fallen below 
10 volts. The ABS has switched off.
The battery might not be charged sufficiently.
When the voltage is above this value 
again, the ABS is operational again and 
the ABS indicator lamp should go out.
If the ABS indicator lamp does not go out:
Have the generator (alternator) and 
the battery checked.
