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.
Emission control
Certain systems of the engine serve to keep the toxic 
components of the exhaust gases within permissible 
limits required by law.
These systems, of course, will function properly only 
when maintained strictly according to factory 
specifications. Any adjustments on the engine should, 
therefore, be carried out only by authorized 
Mercedes-Benz Center qualified technicians. Engine 
adjustments should not be altered in any way. Moreover, 
the specified service jobs must be carried out regularly 
according to Mercedes-Benz servicing requirements. 
For details refer to the Service Booklet.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 
Wa r n i n g !
Inhalation of exhaust gas is hazardous to your 
health. All exhaust gas contains carbon monoxide, 
and inhaling it can cause unconsciousness and 
lead to death. Do not run the engine in confined areas (such as a 
garage) which are not properly ventilated. If you 
think that exhaust gas fumes are entering the 
vehicle while driving, have the cause determined 
and corrected immediately. If you must drive under 
these conditions, drive only with at least one 
window fully open.

Headlamp adjustment
Correct headlamp adjustment is extremely important. 
Check and readjust headlamps at regular intervals and 
when a bulb has been replaced.Replacing bulbs
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.
If the newly installed bulb does not light up, switch the 
lamp off and on again. If the bulb still does not light up, 
have the system checked at an authorized 
Mercedes-Benz Center.
Wa r n i n g !
Bulbs and bulb holders 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.
