additive. For additional treatment, use a chrome
polish.
Light-alloy wheels
For technical reasons, dust is generated during
braking that is deposited on the light-alloy
wheels. Remove the dust regularly using acid-
free rim cleaner.
Do not use aggressive, acidic, strongly
alkaline and abrasive cleaning agents or
steam jets over 1407/606, otherwise dam-
age may occur.<
Outside sensors / cameras
Keep the sensors and cameras on the
outside of the vehicle, e.g. Park Distance
Control, clean and free of ice to ensure that they
remain fully functional.<
Interior care
Upholstery / cloth trim
Vacuum regularly with a vacuum cleaner to
remove superficial dirt.
To treat severe stains, e.g. from beverages, use
a soft sponge or lint-free microfiber cloth in
combination with suitable interior cleaners. Fol-
low the instructions on the packaging.
Clean the upholstery down to the seams
using a sweeping motion. Avoid strong
rubbing.<
Opened Velcro fasteners on pants or
other articles of clothing can damage the
seat covers. Ensure that Velcro fasteners are
closed.<
Leather / leather trim
The leather used by BMW is a high quality
natural product. Slight irregularities in the
leather are a typical characteristic of natural
leather.<
Dust and road grit in the pores and folds of the
leather have an abrasive effect, leading to
increased wear and causing the leather surface
to become brittle prematurely. Therefore, fre-quently clean the leather of dust using a cloth or
vacuum cleaner.
In particular, ensure that light-colored leather is
cleaned regularly as it has a tendency to soil
more easily.
Treat the leather twice a year using a leather
lotion as dirt and grease will gradually attack the
leather's protective layer.
Carpets / cargo bay
You can vacuum the carpets and floor mats or
clean them with interior cleaner if heavily soiled.
The floor mats can be removed for cleaning.
When replacing the mats, ensure that the seat
rails do not extend over the floor mats, as this
may damage the mats.
Lint on the floor mats occurs for technical rea-
sons and can be removed by vacuuming
repeatedly.
Interior plastic parts
>Imitation leather surfaces
>Lamp glasses
>Display pane of instrument cluster
>Matt parts
Clean with water and solvent-free plastic
cleaner if necessary.
Fine wood parts
Clean fine wood trim and fine wood parts with a
damp cloth. Wipe dry with a soft cloth.
Safety belts
Do not clean with cleaning agents as
these may destroy the fabric.<
Interior sensors / cameras
To clean interior sensors and cameras, use a
lint-free cloth moistened with glass cleaner.
Displays
To clean the displays, e.g. of the radio or instru-
ment cluster, use a display cleaning cloth or a
soft, non-abrasive, lint-free cloth.

Care
216 Avoid applying excessive pressure when
cleaning the displays, otherwise damage
may occur.<
Do not use chemical or abrasive house-
hold cleaning agents. Keep all types of
fluid away from the device. Otherwise, surfaces
or electrical components may be corroded or
damaged.<
CD/DVD drives
Do not use a cleaning CD, as it may dam-
age parts of the drive.<
Vehicle storage
If your vehicle is to be decommissioned for
longer than three months, your BMW center or
a workshop that operates according to BMW
specifications will be glad to advise you.

Lamps and bulbs
Lamps and bulbs make an essential contribu-
tion to vehicle safety. They should, therefore,
be handled carefully. BMW recommends hav-
ing your BMW center perform any work that you
do not feel competent to perform yourself or
that is not described here.
Never touch the glass of new bulbs with
your bare fingers, 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.<
You can obtain a selection of replacement bulbs
at your BMW center.
Only change bulbs while they are cool to
the touch, otherwise you could suffer
burns.<
When working on electrical systems,
always begin by switching off the con-
sumer in question, otherwise short-circuits
could result. To avoid possible injury or equip-
ment damage when replacing bulbs, observe
any instructions provided by the bulb manufac-
turer.<
For care of the headlamps, please follow the
instructions in the chapter entitled 'Care'.
If the routine for changing a particular
bulb is not described here, please contact
your BMW center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel.<
Light-emitting diodes LED
Light-emitting diodes installed behind translu-
cent lenses serve as the light source for many of
the controls and displays in your vehicle. These
light-emitting diodes, which operate using a
concept similar to that applied in conventional
lasers, are officially designated as Class 1 light-
emitting diodes.
Do not remove the covers or expose the
eyes directly to the unfiltered light source
for several hours, otherwise this could cause
irritation to the retina.<
Xenon lamps
These bulbs have a very long service life and are
highly unlikely to fail. If a xenon bulb fails never-
theless, switch on the fog lamps and continue
the journey with great care, provided that local
legislation does not prohibit this.
Have any work on the xenon lamp system,
including bulb replacements, performed
only by a BMW center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel. Otherwise, if
such work is carried out improperly, the high
voltage in the system presents the danger of
fatal injuries.<
Access to the bulbs
1.Switch off the lamps and take the remote
control out of the ignition lock.
2.Remove the upper cover from the head-
lamp. To do so, use a screwdriver to press
the catches towards the rear, see arrows,
and pull the cover forward and out.
Follow the same steps in reverse order to reat-
tach the cover.
Be careful when installing the cover, oth-
erwise leaks could occur and cause dam-
age to the headlamp system.<

Changing wheels
Your BMW is equipped with Run-Flat Tires as
standard. This removes the need to change a
wheel immediately in the event of a puncture.
For information on continuing to drive with a
damaged tire, refer to Indication of a flat tire on
page86.
The symbol identifying Run-Flat Tires is a circle
with the letters RSC on the sidewall, refer to
Run-Flat Tires, page204.
When mounting new tires or changing over
from summer to winter tires and vice versa,
mount Run-Flat Tires for your own safety. In the
event of a flat, no spare wheel is available. Your
BMW center will be glad to advise you. Refer
also to New wheels and tires, page204.
The tools for changing wheels are avail-
able as optional accessories from your
BMW center.<
Jack mounting points

Charging the battery
Only charge the battery in the vehicle via the
terminals in the engine compartment with the
engine off. Connections, refer to Jump starting

cling center. Maintain the battery in an upright
position for transport and storage. Always
secure the battery against tipping over during
transport.<
