WARNING
Too 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 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.
Headlight setting
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.
