Malfunction and indicator lamps
in the instrument cluster
General information:
If a bulb in the instrument cluster fails to light up
during the bulb self-check when turning the electronic
key in steering lock to position 2, have it checked and
replaced if necessary.
On-board diagnostic system
Check engine malfunction indicator lamp
Engine malfunction indicator lamp. If the
“CHECK ENGINE” malfunction indicator
lamp comes on when the engine is running,
it indicates a malfunction of the fuel management
system, emission control system, systems which impact
emissions, or the fuel cap is not closed tight (check the
fuel cap). If the “CHECK ENGINE” lamp is illuminated
continuously and the vehicle is driving normally, you
may still drive the vehicle, however, in all cases, we
recommend that you have the system checked at your
authorized Mercedes-Benz Center as soon as possible. If the “CHECK ENGINE” lamp comes on continuously
and / or the vehicle is not driving normally, serious
damage can occur to the emission system. Please
contact your authorized Mercedes-Benz Center
immediately.
The Sequential Multiport Fuel Injection (SFI) control
module monitors emission control components that
either provide input signals to or receive output signals
from the control module. Malfunctions resulting from
interruptions or failure of any of these components are
indicated by the “CHECK ENGINE” malfunction
indicator lamp in the instrument cluster and are
simultaneously stored in the SFI control module.
If the “CHECK ENGINE” malfunction indicator lamp
comes on, have the system checked at your authorized
Mercedes-Benz Center as soon as possible.
With some exceptions, the control module switches off
the “CHECK ENGINE” malfunction indicator lamp if the
condition, causing the lamp to come on, no longer exists
during three consecutive cycles. See also page 246 for
fuel cap placement warning.

LIGHTING SYSTEMWhen the message appears after starting the engine, or
if it come on while driving, this indicates a failure in the
parking lamp, taillamp, stop lamp, or low beam
headlamp. See page 297 for instructions on replacing
bulbs.
If an exterior lamp fails, the message will appear only
when that lamp is switched on.
If a brake lamp fails, the message will appear when
applying the brake and stays on until the engine is
turned off.
Note:
If additional lighting is installed (e.g. auxiliary
headlamps etc.) be certain to connect into the fuse
before the failure indicator monitoring unit order to
avoid damaging the system.

Replacing bulbs
Correct headlamp adjustment is extremely important.
Have headlamps checked and readjusted at regular
intervals and when a bulb has been replaced. See your
authorized Mercedes-Benz Center for headlamp
adjustment. Notes:
To prevent a possible electrical short circuit, switch off
lamp prior to replacing a bulb.
When replacing bulbs, install only 12 volt bulbs with
the specified watt rating.
When replacing halogen bulbs do not touch glass
portion of bulb with bare hands. Use plain paper or a
clean cloth.
Wa r n i n g !
Bulbs and bulb holder can be very hot. Allow the
lamp to cool down before changing a bulb.
Halogen lamps contain pressurized gas. A bulb can
explode if you:
• touch or move it when hot,
•drop the bulb,
•scratch the bulb.Wear eye and hand protection.
Wa r n i n g !
Because of high voltage in Xenon lamps, it is
dangerous to replace the bulb or repair the lamp
and its components. We recommend that you have
such work done by a qualified technician.
