Danger of burns

Headlamp glass

Only change bulbs when they are cool;

otherwise, there is the danger of getting

burned.◀

Condensation can form on the inside of the ex‐

ternal lamps in cool or humid weather. When

driving with the light switched on, the conden‐

sation evaporates after a short time. The head‐

lamp glasses do not need to be changed.

Working on the lighting system

When working on the lighting system,

you should always switch off the lights af‐

fected to prevent short circuits.

If the headlamps do not dim despite driving

with the light switched on, increasing humidity

forms, e. g. water droplets in the light, have the

service center check this.

To avoid possible injury or equipment damage

when replacing bulbs, observe any instructions

provided by the bulb manufacturer.◀

Headlamp setting

The headlamp adjustments can be affected by

changing lamps and bulbs. Therefore after a

change, have the headlamp setting checked

and corrected by Service.

Do not perform work/bulb replacement

on xenon headlamps

Have any work on the xenon lighting system,

including bulb replacement, performed only by

a service center. Due to the high voltage

present in the system, there is the danger of

fatal injuries if work is carried out improperly.◀

Front lamps, bulb replacement

Halogen headlamps

Do not touch the bulbs

Do not touch the glass of new bulbs with

your bare hands, as even minute amounts of

contamination will burn into the bulb's surface

and reduce its service life.

Use a clean tissue, cloth or something similar,

or hold the bulb by its base.◀
