tact with the bulbs can cause burns. There is a
risk of injury. Only change bulbs after they
have cooled off.◀
Light-emitting diodes (LEDs)
WARNING
Some items of equipment use light-emitting
diodes 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.
Work on switched-on lighting systems
can cause short circuits. There is a risk of in‐
jury or risk of property damage. When working
on the lighting system, switch off the lamps in
question. If necessary, heed the bulb manufac‐
turer's instructions.◀
Observe the safety information, refer to
page 228.
NOTE
Headlight glass
Dirty bulbs have a reduced service life.
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.◀
Condensation can form on the inside of the ex‐
ternal lights in cool or humid weather. When
driving with the lights switched on, the con‐
densation evaporates after a short time. The
headlight 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
service center or another qualified service cen‐
ter or repair shop.

DANGER
There can be high voltage in the lighting
system. There is danger to life. The manufac‐
turer of your vehicle recommends that the
work on the lighting system including bulb re‐
placement be performed by a dealer’s service
center or another qualified service center or re‐
pair shop.◀

The headlight adjustments can be affected by
changing lights and bulbs. After the headlight
adjustment was changed, have it checked and,
if necessary, corrected by a dealer’s service
center or another qualified service center or re‐
pair shop.
