ist workshop, if you are not familiar with it or it
is not described here.
A box containing spare bulbs is available from
a Service Partner or a qualified specialist work‐

WARNING
Lamps can become hot during operation.
Contact with the lamps can lead to burns. Dan‐
ger of injury. Only replace lamps in cooled-
down condition.◀
WARNING
Short circuits can occur when working on
switched on lighting systems. Danger of injury
or damage to property. Switch the respective
lights off when working on the lighting system.
Observe the possibly enclosed notes of the
lamp manufacturer.◀
DANGER
High voltages can be applied to the light‐
ing system. Danger of fatal injury. Have work
on the lighting system including replacing the
lamps performed by a Service Partner or a
qualified specialist workshop.◀
ATTENTION
Dirty lamps have a reduced lifetime. Dan‐
ger of damage to property. Do not touch the
glass of new lamps with your bare hands. Use
a clean tissue, cloth or similar, or hold the bulb
by its base.◀
Light-emitting diodes, LEDs
Some equipment versions have light-emitting
diodes behind a cover as a light source.
These resemble conventional lasers and are
classified by legislation as Class 1 light-emit‐
ting diodes.
WARNING
Excessively intense brightness can irri‐
tate or harm the retina of the eye. Danger of in‐
jury. Do not look directly at the headlights orother light sources for a sustained period. Do
not remove covers from LEDs.◀
Headlight glass
During cool or humid weather, the exterior
lights can mist over. When driving with the light
switched on, the condensation disappears af‐
ter a short time. There is no need to replace
the headlight glass.
If the headlights do not demist, even when
driving with the lights switched on and increas‐ ing moisture builds up, for example water
droplets in the lights, have these checked by a
Service Partner or a qualified specialist work‐
shop.
Headlight adjustment The adjustments of the headlight can be affec‐
ted by changing lights and bulbs. Have the
headlight adjustment checked and if necessary
corrected by a Service Partner or a qualified
specialist workshop after changing lights and
lamps.

Xenon headlight Notes DANGER
High voltages can be applied to the light‐
ing system. Danger of fatal injury. Have work
on the lighting system including replacing the
lamps performed by a Service Partner or a
qualified specialist workshop.◀
These bulbs have a very long service life and
are highly unlikely to fail. Frequent switching
on and off shortens the service life.Seite 194MobilityReplacing parts194

Cleaning agents can contain hazardous
substances or constitute a health risk. Danger
of injury. When cleaning the interior, open the
doors or windows. Use only products that are
intended for cleaning the vehicle's interior. Ob‐
serve the notes on the pack.◀
Vehicle paintwork Regular care promotes driving safety and pre‐
serves your vehicle's value. Environmental ef‐
fects in areas with higher air pollution or natu‐
ral contaminations, for example tree resin or
leaf dust, may have an effect on the vehicle
paintwork. Base the frequency and extent of
vehicle care on such factors.

fuel, oil, grease or bird droppings immediately
to avoid changes to the paint or discoloura‐
tions.

Leather care
Remove dust from the leather at regular inter‐
vals with a cloth or vacuum cleaner.
Dust and road dirt will otherwise become
worked into pores and folds, causing consider‐
able abrasion and causing the leather surface
to become prematurely brittle.
In order to protect against discolouration, for
example from clothing, clean the leather ap‐
proximately every two months.
Clean light-coloured leather more frequently
as it has the tendency to soil faster.
Use leather cleaner, otherwise dirt and grease
will attack the protective coating of the leather.
Suitable care products are available from a
Service Partner or a qualified specialist work‐
shop.
Care of upholstery fabrics
Clean regularly with a vacuum cleaner.
In the event of heavy soiling, for example stains
caused by drinks, use a soft sponge or a lint-
free microfibre cloth with suitable interior
cleaning agents.
Clean upholstery materials over a large area up
to the seams. Avoid strong rubbing.
ATTENTION
Open Velcro fasteners on articles of
clothing can damage the seat covers. Danger
of damage to property. Make sure that any Vel‐
cro fasteners on your clothing are closed.◀
Care of special parts
Light alloy wheels Only when cleaning on the vehicle use neutral
rim cleaner with a pH value of between 5 and 9.
Do not use any rough cleaner or steam cleaner
above 60 ℃/140 ℉. Observe the manufactur‐
er's information.Corrosive, acidic or alkaline cleaners may de‐
stroy the protective layer of neighbouring
parts, such as brake discs, for example.
Chrome surfaces Carefully clean parts such as the radiator grille
and door handles with plenty of water to which
a shampoo may be added, particularly if ex‐
posed to road salt.
Rubber parts
The surfaces of rubber parts can be contami‐
nated or loose their shine due to environmental
influences. Only use water and suitable care
products for cleaning. The manufacturer of
your vehicle recommends genuine BMW care
products.
Treat particularly stressed rubber parts at reg‐
ular intervals with rubber care products. Do not
use any silicone-based care products for treat‐
ing rubber seals, otherwise these could be
damaged and become a source of noise.
Fine wood parts Clean fine wood trims and fine wood parts with
a damp cloth only. Then dry them with a soft
cloth.
Plastic parts
These include:▷Imitation leather surfaces.▷Roof lining.▷Light covers.▷Glass cover of instrument cluster.▷Parts sprayed matt black.▷Painted parts in the interior.
Use a microfibre cloth to clean.
Slightly moisten the cloth with water.

Cleaning agents containing alcohol or
solvents, such as nitro thinners, cold cleans‐
ers, fuel or similar can damage plastic parts.
Danger of damage to property. Use a microfi‐
bre cloth to clean. Slightly moisten the cloth

strict the pedal travel, or block a pedal that has
been pressed. Danger of accidents. Stow
items in the vehicle so that they are secure and
cannot get into the driver's footwell. Only use
floor mats that have been categorised as ap‐
propriate for the vehicle and that can be fas‐
tened accordingly. Do not use any loose floor
mats, and do not place several floor mats on
top of one another. Make sure that there is suf‐
ficient space for the pedals. Ensure that the
floor mats are securely reattached after having
been removed, for example for cleaning.◀
Floor mats can be removed from the vehicle to
enable the interior to be cleaned more thor‐
oughly.
In the event of heavy soiling, clean floor car‐
pets using a microfibre cloth and water or tex‐tile cleaner. In doing so, rub back and forth in
the direction of travel, otherwise the carpet can
