When using a steam cleaner or power
washer, aim nozzle only briefly from a min-
imum distance of 12 in (30 cm) at
sensors1.
Do not apply strong pressure to the sensor
cover, applying strong pressure may dam-
age the sensor cover.To prevent scratches, never apply strong

340 Practical hintsWhat to do if …?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 theignition, have the respective bulb checked
and replaced if necessary.Problem
Possible cause
Suggested solution
-
The yellow Antilock Brake
System (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 multi-
function 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*, 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 353).
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 charging voltage has fallen below
10 volts and the ABS has switched off.
The battery may not be charged sufficiently.
Switch off electrical consumers that are
currently not needed, e.g. seat heat-
ing*.
If necessary, have the generator
(alternator) and battery checked.
When the voltage is above this value again,
the ABS is operational again.
