Be careful when replacing high voltage xenon headlight bulbs! Just in case, turn off the headlight and disconnect the battery. After replacement, briefly turn the headlight on and off to remove residual voltage. For safety reasons, wear shoes with rubber soles.
Incandescent lamps and lamp holders can become very hot. Therefore, before replacing incandescent lamps, wait until the lighting fixture has cooled down.
Keep lamps out of the reach of children.
Do not use lamps that have been dropped or scratched as they may burst.
Note. The glass bulb of the incandescent lamp should not be taken by hand. To do this, it is best to use napkins or cotton gloves. Fingerprints evaporate and deposit on the reflector, clouding it. Accidental stains on the flask should be removed with a clean, lint-free towel soaked in alcohol.
Incandescent lamps must only be replaced with lamps of the same design.

If after replacement the incandescent lamp does not light, switch the lighting off and on again. If the replaced incandescent lamp does not light after that, contact a service station «Mercedes-Benz».
Attention! The plastic headlight lenses have a protective coating. In no case should they be cleaned and even more so rubbed with a dry cloth. It is also impossible to use any cleaners or solvents for this purpose. Such diffusers should be cleaned with a clean, soft towel.
Before replacing a lamp, make sure that the corresponding switch is turned off.
