Lights and bulbs
General information
Lights and bulbs make an essential contribution
to vehicle safety.
All headlights and lights are made using LED or
laser technology.
Some items of equipment use light-emitting di‐
odes installed behind a cover as a light source.
These light-emitting diodes are related to con‐
ventional lasers and are officially designated as
Class 1 light-emitting diodes.
The manufacturer of the vehicle recommends
that you let a dealer's service center or another
qualified service center or repair shop perform
the work in case of a malfunction.
Safety information

Focused laser light can irritate or permanently
damage the retina of the eye. There is a risk of
injury. The manufacturer of your vehicle recom‐
mends that the work on the lighting system in‐
cluding bulb replacement be performed by a
dealer’s service center or another qualified
service center or repair shop.
Warning
Intensive brightness can irritate or damage the
retina of the eye. There is a risk of injury. Do not
look directly into the headlights or other light
sources. Do not remove the LED covers.
Headlight glass
Condensation can form on the inside of the

driving with the lights switched on, the conden‐
sation evaporates after a short time. The head‐

droplets in the light, have the headlights
checked.
