checked and replaced if necessary.
ProblemPossible cause/consequenceSuggested solution
-The yellow ABS indicator lamp comes on
when the engine is running.The ABS has detected a malfunction
and has switched off. The BAS and
ESP
® are also switched off (see mes-
sages in the multifunction display).
The brake system is still functioning
normally but without the systems
specified above.
If the ABS control unit is malfunction-
ing, other systems such as the naviga-
tion system* or the automatic
transmission* may also be malfunc-
tioning.
Continue driving with added caution.
Wheels may lock during hard braking,
reducing steering capability.
Read and observe messages in the
multifunction display (
page 356).
Have the system checked at an
authorized Mercedes-Benz Center as
soon as possible.
Failure to follow these instructions in-
creases the risk of an accident.

10 volts. The ABS has switched off.
The battery might not be charged suf-
ficiently.When the voltage is above this value
again, the ABS is operational again an the
ABS indicator lamp should go out.
If the ABS indicator lamp does not go out:
Have the generator (alternator) and
battery checked.

starts to skid or that a wheel is
spinning.
The cruise control is deactivated
and cannot be switched on.
Switch the ESP® back on (page 89).

#The battery is no longer charging.
Possible causes:
Alternator malfunctioning
Broken poly-V-belt
Do not forget that the brake system
requires electrical energy and may
be operating with restricted capa-
bility. Considerably greater brake
pedal force is required and the stop-
ping distance is increased.
Stop the vehicle immediately in a safe loca-
tion and check the poly-V-belt.
If it is broken:
Do not continue to drive.
Otherwise, the engine will overheat due
to an inoperative water pump which may
result in damage to the engine. Contact
an authorized Mercedes-Benz Center.
If it is in order:
Contact an Mercedes-Benz Center
immediately. Adjust driving to be consis-
tent with reduced braking responsive-
ness.

Lift up trunk floor.Vehicle jack
Warning!G
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into both sides of the vehicle. To help
avoid personal injury, use the jack only to lift
the vehicle during a wheel change. Never
get beneath the vehicle while it is supported
by the jack. Keep hands and feet away from
the area under the lifted vehicle. Always
firmly set parking brake and block wheels
before raising vehicle with jack.
Do not disengage parking brake while the
vehicle is raised. Be certain that the jack is
always vertical (plumb line) when in use,
especially on hills. Always try to use the jack
on level surface. Make sure the jack arm is
fully seated in the jack take-up bracket. Al-
ways lower the vehicle onto sufficient
capacity jackstands before working under
the vehicle.
