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 (

Keep bulbs out of reach of children.
Bulbs and bulb sockets can be very hot.
Allow the lamp to cool down before
changing a bulb.
Halogen lamps contain pressurized gas.
A bulb can explode if you:

touch or move it when hot

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.
