Lamps in instrument cluster
General information:
If any of the following lamps in the instru-
ment cluster fails to come on during the
bulb self-check when switching on the igni-
tion, have the respective bulb checked and
replaced if necessary.
ProblemPossible cause/consequenceSuggested solution
-The yellow Antilock
Brake System (ABS)
indicator lamp comes on
while the engine is run-
ning.The ABS has detected a malfunction and
has switched off. The BAS, ESP®, EBP and
PRE-SAFE® are also switched off (see mes-
sages in multifunction display).
The brake system is still functioning nor-
mally but without the ABS available.
If the ABS control unit is malfunctioning,
other systems such as Parktronic*,
DISTRONIC Plus*, navigation system, Park
Assist* and 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 mul-
tifunction display (
page 612).
Have the system checked at an autho-
rized Mercedes-Benz Center as soon as
possible.
Failure to follow these instructions increas-
es the risk of an accident.

-The yellow Antilock
Brake System (ABS)
indicator lamp comes on
while the engine is run-
ning.The charging voltage has fallen below
10 volts. The ABS has switched off.
The battery may not be charged sufficiently.When the voltage is above this value again,
the ABS is operational again and the ABS in-
dicator lamp should go out.
If the ABS indicator lamp does not go out:
Have the generator (alternator) and the
battery checked.
When the voltage is above this value again,
the ABS is operational again.

Vehicle status messages in the multi-
function display
Warning and malfunction messages ap-
pear in the multifunction display located in
the instrument cluster.
Certain warning and malfunction messag-
es are accompanied by an audible signal.
High-priority messages are shown in red
on the multifunction display. Messages of
lower priority are also shown in yellow or
white.
Address these messages accordingly and
follow the additional instructions given in
this Operator’s Manual.Certain messages of high priority cannot
be cleared from the multifunction display
using# or L on the multifunction
steering wheel (
page 265).
Other messages of high priority and mes-
sages of less immediate priority can be
cleared from the multifunction display
using# or L. They are then stored
in the vehicle status message memory
(
page 280). Remember that clearing a
message will only make the message dis-
appear. Clearing a message will not cor-
rect the condition that caused the
message to appear.
Warning!G
No messages will be displayed if either the
instrument cluster or the multifunction dis-
play is inoperative.
As a result, you will not be able to see infor-
mation about your driving conditions, such
as speed or outside temperature, warn-
ing/indicator lamps, malfunction/warning
messages or the failure of any systems.
Driving characteristics may be impaired.
If you must continue to drive, please do so
with added caution. Contact an authorized
Mercedes-Benz Center as soon as possible.
