Hints

Do not fold down the wipers without

wiper blades

Lights and bulbs

Lights and bulbs make an essential contribu‐

tion to vehicle safety.

Replacing components

Headlight glass

Mobility

You can obtain a selection of replacement

bulbs at the service center.

Condensation can form on the inside of the ex‐

ternal lights in cool or humid weather. When

driving with the light switched on, the conden‐

sation evaporates after a short time. The head‐

light glass does not need to be changed.

Danger of burns

Only change bulbs when they are cool;

otherwise, there is a danger of getting

burned.◀

If the headlights 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.

Working on the lighting system

When working on the lighting system,

you should always reel off the lights affected to

prevent short circuits.

Headlight setting

To avoid possible injury or equipment damage

when replacing bulbs, observe any instructions

provided by the bulb manufacturer.◀

The headlight adjustments can be affected by

changing lights and bulbs. Have the head‐

lights' settings checked and corrected by serv‐

ice after a replacement.

Do not perform work/bulb replacement

on xenon headlights

Front lights, bulb replacement

Xenon headlights

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 a danger of fatal

injuries if work is carried out improperly.◀

Xenon headlights

Because of the long life of these bulbs, the

likelihood of failure is very low. Switching the

lights on and off frequently shortens their life.

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.

Do not perform work/bulb replacement

on xenon headlights

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 a danger of fatal

injuries if work is carried out improperly.◀

Use a clean tissue, cloth or something similar,

or hold the bulb by its base.◀

Light-emitting diodes (LEDs)

Some items of equipment use light-emitting

diodes installed behind a cover as a light

source.

For checking and adjusting headlamp aim,

please contact your BMW center.

These light-emitting diodes, which are related

to conventional lasers, are officially designated

as Class 1 light-emitting diodes.

Do not remove the covers

Do not remove the covers, and never

stare into the unfiltered light for several hours;

otherwise, irritation of the retina could result.◀
