ries or a risk of property damage. When work‐
ing on the lighting system, switch off the lamps
in question. If necessary, heed the bulb manu‐
facturer's instructions. ◀

There is a risk of property damage. Do not hold
new bulbs with your bare hands. Use a clean
cloth or something similar, or hold the bulb by
its base. ◀
Light-emitting diodes (LEDs) Some items of equipment use light-emitting di‐
odes installed behind a cover as a light source.These light-emitting diodes, which are related
to conventional lasers, are officially designated
as Class 1 light-emitting diodes.

damage the retina of the eye. There is a a risk
of injury. Do not look directly into the head‐
lights or other light sources. Do not remove the

ternal lights in cool or humid weather. When
driving with the lights switched on, the conden‐
sation evaporates after a short time. The head‐
light glass does not need to be changed.
If despite driving with the lights switched on,
increasing humidity forms, e. g. water droplets
in the lamp, the manufacturer of your vehicle
recommends having it checked by a dealer’s
