If a bulb in the instrument cluster fails to
come on during the bulb self-check when
switching on ignition, have it checked and
replaced if necessary.
Problem Possible cause Suggested solution
- The yellow ABS malfunction
indicator lamp comes on while
driving.
The ABS has detected a malfunction and has
switched off. The BAS and the ESP are also
switched off (see messages in 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.
왘 Continue driving with added caution.
Wheels may lock during hard braking,
reducing steering capability.
왘 Read and observe messages in the
display (컄 page 309).
왘 Have the system checked at an autho-
rized Mercedes-Benz Center as soon
as possible.
Failure to follow these instructions
increases the risk of an accident.
The charging voltage has fallen below ten
volts. The ABS has switched off.
The battery might not be charged sufficiently.
왘 Switch off electrical consumers that
are currently not needed, e.g. seat
heating*.
왘 If necessary, have the generator
(alternator) and battery checked.
When the voltage is above this value
again, the ABS is operational again.

Warning! G
Driving with the brake warning lamp illumi-
nated can result in an accident. Have your
brake system checked immediately if the
brake warning lamp stays on. Don’t add
brake fluid before checking the brake
system. Overfilling the brake fluid reservoir
can result in spilling brake fluid on hot
engine parts and the brake fluid catching
fire. You can be seriously burned.
!
If you find that the brake fluid in the
brake fluid reservoir has fallen to the
minimum mark or below, have the
brake system checked for brake pad
thickness and leaks.

The yellow engine malfunction
indicator lamp comes on while
driving.
There is a malfunction in:
앫 The fuel management
system
앫 The ignition system
앫 The emission control
system
앫 Systems which affect
emissions
Such malfunctions may result

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
(
컄 page 130) 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 (
컄 page 117).
Other messages of high priority and
messages of less immediate priority can
be cleared from the multifunction display
using the reset button (
컄 page 117). They
are then stored in the vehicle status mes-
sage memory (컄 page 130). Remember
that clearing a message will only make the
message disappear. Clearing a message
will not correct the condition that caused
the message to appear.
On the pages that follow, you will find a
compilation of the most important warning
and malfunction messages that may
appear in the multifunction display. High
priority messages appear in red color.
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 Center.
Failure to repair condition noted may cause
damage not covered by the Mercedes-Benz
Limited Warranty, or result in property
damage or personal injury.
Warning! G
No messages will be displayed if either the
instrument cluster or the multifunction
display is inoperative.
Contact your nearest authorized
Mercedes-Benz Center.
