tion indicator lamp comes
on while driving.
There is a malfunction in:
The fuel management system

The ignition system

The emission control system

Systems which affect emissions

emissions values and may switch the en-

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

It allows the accurate identification of
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.
Your fuel tank is empty.

After refuelling, start, turn off, and re-
start the engine three or four times in
succession.

The yellow warning lamp for the
tire inflation pressure monitor
comes on.
The tire inflation 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.

Read and observe messages in the mul-
tifunction display.
The warning lamp goes out once the tire in-
flation pressure monitor has been reactivat-
ed after the tire inflation pressures have
been corrected.
Warning!
G
When the tire inflation pressure monitoring
system warning light is lit, one or more of
your tires is significantly under-inflated. You
should stop and check your tires as soon as
possible, and inflate them to the proper
pressure as indicated on the vehicle’s tire in-
formation placard. Driving on a significantly
under-inflated tire causes the tire to over-
heat and can lead to tire failure.
Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the vehi-
cle’s handling and stopping ability. Each tire,
including the spare, should be checked
monthly when cold and set to the recom-
mended inflation pressure as specified in
the vehicle placard and owner’s manual.
iThe recommended tire inflation pres-
sures for your vehicle can be found on
the tire placard on the driver’s door
B-pillar or, if available, the inside of the
fuel filler flap, not in the owner’s
manual.
