316 Practical hintsReplacing bulbs
Replacing bulbsSafe 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 your autho-
rized Mercedes-Benz Center for headlamp
adjustment.
Bulbs
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


Brake lamps


Parking lamps


Tail lamps

318 Practical hintsReplacing bulbs

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 light
up, visit an authorized Mercedes-Benz
Center.


Have the LEDs and bulbs for the follow-
ing lamps replaced by an authorized
Mercedes-Benz Center.
