Problem Possible cause Suggested solution
- The yellow ABS malfunction indi-
cator lamp comes on while driv-
ing.
You engaged the differential locks. The ABS,
ESP, BAS, EBB and 4-ETS are switched off.
̈ The driving systems will switch on
again after the differential locks have
been disengaged.
The ABS has detected a malfunction and has
switched off. The ESP, BAS, EBB and 4-ETS
are also switched off (see messages in dis-
play).
If the ABS control unit is malfunctioning, oth-
er systems such as the navigation system or
Rear Park Assist* may also malfunction.
The brake system is still functioning normally
but without the ABS available.
̈ Continue driving with added caution.
Wheels will 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 ABS has switched off because charging
voltage has fallen below 10 volts. The battery
may not be charged.
̈ Turn off unnecessary electric con-
sumers.
When the battery voltage is above this
value again, the ABS is operational
again.

tion display (
