The yellow ABS malfunction in-
dicator 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 nor-
mally but without the ABS available.
If the ABS control unit is malfunctioning,
other systems such as Parktronic*, Distron-
ic*, and the automatic transmission may
also be malfunctioning.

Continue driving with added caution.
Wheels may lock during hard braking,
reducing steering capability.

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.
When the voltage is above this value again,
the ABS is operational again.
If necessary, have the generator and

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.

tion) mode.

Have the vehicle checked as soon as
possible by an authorized
Mercedes-Benz Center.
An on-board diagnostic connector is
used by the service station to link the

system malfunctions through the read-
out of diagnostic trouble codes. It is lo-
cated in the front left area of the
footwell next to the parking brake pedal.
The fuel cap is not closed tightly.

Check the fuel cap (

The yellow warning lamp for the
tire pressure monitor comes on.
The tire pressure monitor detects a loss of
pressure in at least one tire.

Bring the vehicle to a halt, avoiding
abrupt steering and braking maneuvers.
Observe the traffic situation around you.

Take note of the messages in the multi-
function display.
Warning!
G
When the tire pressure monitoring system
warning lamp is lit, one or more of your tires
is significantly under-inflated. You should
stop and check your tires as soon as possi-
ble, and inflate them to the proper pressure
as indicated on the vehicle’s tire information
placard.
Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
Each tire, including the spare, should be
checked monthly when cold and set to the
recommended inflation pressure as speci-
fied in the vehicle placard and owner’s
manual.
iThe recommended tire inflation pres-
sure for your vehicle can be found on
the inside of the fuel filler flap, not in
the owner’s manual.
