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.
