Bulbs
Safe vehicle operation depends on proper
exterior lighting and signaling. It is there-
fore essential that all bulbs and lamp as-
semblies are in good working order at all
times.
Correct headlamp adjustment is extremely
important. Have headlamps checked and
readjusted at regular intervals and when a
bulb has been replaced. See an authorized
Mercedes-Benz Center for headlamp ad-
justment.
iIf the headlamps are fogged up on the
inside as a result of high humidity, driv-
ing the vehicle a distance should clear
up the fogging.
iBackup bulbs will be brought into use
when the following lamps malfunction:

Turn signal lamps

Notes on bulb replacement

Only use 12 volt bulbs of the same type
and with the specified watt rating.


Switch lights off before changing a bulb
to prevent short circuits.


Always use a clean lint-free cloth when
handling bulbs.


Your hands should be dry and free of oil
and grease.


If the newly installed bulb does not
come on, visit an authorized
Mercedes-Benz Center.Have the LEDs and bulbs for the following
lamps replaced by an authorized
Mercedes-Benz Center:


the additional turn signals in the exteri-
or rear view mirrors


the high mounted brake lamp


the brake lamps


the parking lamps and the side marker
lamps in the tail lamp assemblies


the rear fog lamps


the low beam (Xenon or Bi-Xenon*)
lamps


the front fog lamps
Warning!
G
Bulbs and bulb sockets can be very hot. Al-
low the lamp to cool down before changing
a bulb.
Keep bulbs out of reach of children.
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.
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.
