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. Contact your au-
thorized Mercedes-Benz Center for head-
lamp 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
Substitute bulbs will be brought into use
when lamps malfunction. Read and observe mes-
sages in the multifunction display (

Warning!

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 Bi-Xenon* lamps,
it is dangerous to replace the bulb or repair
the lamp and its components. We recom-
mend that you have such work done by a
qualified technician.
