400 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
assemblies 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 an
authorized Mercedes-Benz Center for
headlamp adjustment.
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.
iIf the headlamps are fogged up on the inside
as a result of high humidity, driving the vehicle a
short distance with the lights on should clear up
the fogging.
iBackup bulbs will be brought into use
when lamps malfunction. Read and observe
the messages in the multifunction
display (
page 381).
