Practical hints
Replacing bulbs
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.
i If the headlamps or front fog lamps are
fogged up on the inside as a result of high humid-
ity, driving the vehicle a distance with the lights
on should clear up the fogging.
i Auxiliary bulbs will be brought into use when
lamps malfunction. Read and observe the mes-
sages in the multifunction display (
୴ page 382).
