Notes on bulb replacement
Warning!
Keep bulbs out of reach of children.
Bulbs and bulb sockets can be very hot. Al-
low 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
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.
Use only 12-volt bulbs of the same type
and with the specified watt rating.
G
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
Light Truck Center.
Have the LEDs and bulbs for the follow-
ing lamps replaced by an authorized
Mercedes-Benz Light Truck Center:
Additional turn signals in the exteri-
or rear view mirrors

package)*
