Lamps in instrument clusterGeneral information:
If any of the following lamps in the instru-
ment cluster fails to come on during thebulb self-check when switching on the
ignition, have the respective bulb checked
and replaced if necessary.
ProblemPossible cause/consequenceSuggested 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 (
page 413).
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.

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
(
page 162) 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 (
page 145) or
buttonj,k,ÿ, orè on the
multifunction steering wheel.
Other messages of high priority and mes-
sages of less immediate priority can be
cleared from the multifunction display
using the reset button (
page 145) or
buttonj,k,ÿ, orè on the
multifunction steering wheel. They are
then stored in the vehicle status message
memory (
page 162). Remember that
clearing a message will only make the mes-
sage disappear. Clearing a message will
not correct the condition that caused the
message to appear.
Warning!G
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 Light Truck
Center.

age or personal injury.
