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.

WARNING

Bulbs can get hot during operation. Con‐

tact with the bulbs can cause burns. There is a

risk of injury. Only change bulbs after they

have cooled off.◀

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.

WARNING

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

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.
