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 your autho-
rized Mercedes-Benz Center for headlamp
adjustment.
iIf the headlamps or front fog lamps are
fogged up on the inside as a result of
high humidity, driving the vehicle a dis-
tance with the lights on should clear up
the fogging.
iSubstitute bulbs will be brought into
use when lamps malfunction. Observe
the messages in the multifunction dis-
play (
page 392).

Notes on bulb replacement

Use only 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 following
lamps replaced by an authorized
Mercedes-Benz Center:


Additional turn signals in the exterior
rear view mirrors

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.
