Notes on bulb replacement
Only use 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

Have the LEDs and bulbs for the follow-
ing lamps replaced by an authorized
Mercedes-Benz Center:

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

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-
