If any of the following bulbs in the instru-
ment cluster fails to come on during thebulb self-check when switching on the igni-
tion, have the respective bulb checked and
replaced if necessary.Problem
Possible cause/consequence
Suggested solution
-
The yellow ABS 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.
Continue driving with added caution.
Wheels will lock during hard braking,
reducing steering capability.
Read and observe messages in the
multifunction display (
page 383).
Have the system checked at an autho-
rized Mercedes-Benz Center as soon
as possible.
Failure to follow these instructions in-
creases the risk of an accident.
The charging voltage has fallen below
10 volts and the ABS has switched off.
The battery might not be charged sufficiently.
Switch off electrical consumers that
are currently not needed, e.g. seat
heating*.
If necessary, have the generator (al-
ternator) and battery checked.
When the voltage is above this value
again, the ABS is operational again.

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 146) 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 136) or
button k,j, è, orÿ on the
steering wheel.
Other messages of high priority and
messages of less immediate priority can
be cleared from the multifunction display
using the reset button (page 136) or
button k,j, è, orÿ on the
steering wheel. They are then stored in the
vehicle status message memory
(
page 146). Remember that clearing a
message will only make the message dis-
appear. 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 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.

The dimensions of the Minispare wheel are
different from those of the road wheels. As
a result, the vehicle handling characteristics
change when driving with a Minispare wheel
mounted. Adapt your driving style
accordingly.
The spare wheel is for temporary use only.
When driving with spare wheel mounted,
ensure proper tire inflation pressure and do
not exceed a vehicle speed of 50 mph
(80 km/h).
Drive to the nearest Mercedes-Benz Center
as soon as possible to have the spare wheel
replaced with a regular road wheel.
Never operate the vehicle with more than
one Minispare wheel mounted.
Do not switch off the ESP
® when a Minis-
pare wheel is mounted.
iOpen door only when conditions are
safe to do so.
