Wheels and tires
230 with correspondingly trained personnel. If this
work is not carried out properly, there is a dan-
ger of subsequent damage and related safety
hazards. Make sure that the new wheels are bal-
anced.<
Retreaded tires
BMW does not recommend that you use
retreaded tires, as driving safety may be
impaired. The causes for this include the possi-
bly different tire casing structures and the often
wide variations in their age, which can result in a
limited service life.<
The right wheels and tires
BMW recommends that you use only
wheel and tire combinations that BMW
has tested and approved for your particular
vehicle. Variations in factors such as manufac-
turing tolerances mean that even wheels and
tires with identical official size ratings could
actually have different dimensions than the
approved units – these differences could lead to
body contact, and with it the risk of severe acci-
dents. If non-approved wheels and tires are
used, BMW cannot evaluate their suitability,
and therefore cannot be held liable for driving
safety.<
You can inquire about the right wheel/tire com-
bination at your BMW center.
The correct wheel/tire combination also affects
various systems whose function would other-
wise be impaired, e.g. ABS, DSC or xDrive.
To maintain good handling and vehicle
response, use only tires of a single tread config-
uration from a single manufacturer. Following
tire damage, have the original wheel and tire
combination remounted on the vehicle as soon
as possible.
Wheels with electronics for
TPM Tire Pressure Monitor
When mounting new tires or converting from
summer to winter tires or vice versa, only use
wheels with TPM electronics, otherwise the
Tire Pressure Monitor cannot detect a flat tire, refer to page97. Your BMW center will be
happy to advise you on this subject.
Recommended tire brands
Certain tire makes are recommended by BMW
depending on the tire size. You can recognize
these from the clearly visible BMW marking on
the tire sidewall.
When used properly, these tires comply with
the most demanding standards for safety and
vehicle response.
Run-flat tires
When mounting new tires, or changing from
s u m m e r t o w i n t e r t i r e s o r v i c e v e r s a , u s e r u n - f l a t
tires for your own safety. In addition, no spare
tire is available in case of a flat tire. Your BMW
center will be glad to advise you.
Special characteristics of winter tires
BMW recommends winter tires for use in cold
winter driving conditions. Although all-season
M+S tires provide better winter traction than
summer tires, they generally fail to provide the
same levels of cold-weather performance as
winter tires.
Paying attention to speed
Always observe the maximum permissi-
ble speed for the winter tires, otherwise
tire damage may occur, which can result in acci-
dents.<
Storage
Store wheels and tires in a cool, dry place with
as little exposure to light as possible. Always
protect tires against all contact with oil, grease

Care
Car-care products
Regular cleaning and care make a significant
contribution to retaining your BMW's value.
For the cleaning and care of your vehicle, BMW
recommends using only products that BMW
has approved for this purpose.
Your BMW center will be glad to advise you
about products and services for the cleaning
and care of your BMW.
Genuine BMW Care Products are materi-
als tested, laboratory tested, and tested in
actual use. They offer optimum care and pro-
tection for your vehicle.<
Do not use cleaners that contain alcohol
or solvents; they can damage your vehi-
cle.<
Cleaning agents can contain substances
that are dangerous or pose health risks.
You should therefore heed the warnings and
hazard indications on the packaging. Open the
doors or windows on your vehicle whenever
cleaning the interior. Make sure there is suffi-
cient ventilation in enclosed spaces. Use only
products that are formulated for vehicle clean-
ing.<
Exterior care
Washing your vehicle
In the winter months, it is especially
important to ensure that the vehicle is
washed on a regular basis. Otherwise, signifi-
cant soiling and road salt can cause damage to
the vehicle.<
After washing the vehicle, apply the
brakes briefly to dry them. Failure to do so
may lead to a reduction in braking efficiency and
also to corrosion of the brake rotors.<
Car washes
Give preference to cloth car washes.Before driving into the car wash, make sure that
it is suitable for your BMW. Pay attention to the
following points:
>Dimensions of your vehicle, refer to
page261.
>If necessary, fold in the outside rearview
mirrors, refer to page55.
>Maximum permissible tire width.
Preparations for driving into the car wash:
>Deactivate rain sensor to prevent unwanted
wiper activation.
>Deactivate rear window wiper
* and protect
it from damage. Take appropriate protec-
tive measures; inquiring with the car wash
operator as needed.
>Remove additional add-on parts, e.g. spoil-
ers or phone antennas, if they could be
damaged.
Automatic transmission
Before driving into the car wash, make sure the
vehicle is able to roll by making sure to:
1.Insert the remote control into the ignition
lock, even with comfort access.
2.Shift into transmission position N.
3.Release the parking brake.
4.Switch off the engine.
5.Leave the remote control in the ignition lock
so that the vehicle can roll.
Steam cleaners/high-pressure
cleaning jets
When using steam jets or high-pressure
washers, ensure that you maintain suffi-
cient clearance to the vehicle and do not exceed
a temperature of 1407/606.
Insufficient distance or excessive pressure or
temperature can damage parts of the vehicle or
can result in water penetration. Follow the oper-
ating instructions for the high-pressure clean-
ing jets.<

Care
240 When using high-pressure cleaning jets,
do not remain in one place for a long time
and be sure to maintain a distance of at least
12 in/30 cm from sensors, e.g. Park Distance
Control sensors or radar sensors.<
Hand washing
When washing the vehicle by hand, use plenty
of water and car washing shampoo. Clean the
vehicle with gentle pressure using a sponge or a
washing brush.
Before cleaning the windshield, deacti-
vate the rain sensor or switch off the igni-
tion to prevent unwanted wiper operation.<
Follow local guidelines for washing vehi-
cles by hand.<
Headlamps
Do not rub dry and never use abrasives or
strong solvents to clean the covers.
Loosen dirt, e.g. insects, with shampoo or
insect remover and wash away with plenty of
water.
Use a window de-icer to remove accumulated
ice and snow, not a scraper.
Windows
Use a glass cleaner to clean the inside and out-
side surfaces of the windows and the glass sur-
faces of the mirrors.
Do not use quartz-containing cleansers
to clean glass surfaces of the mirrors.<
Wiper blades
Clean with soapy water and replace regularly to
prevent streaking.
The presence of wax and sealant residues
and dirt on the windows leads to streaking
during wiper operation and results in premature
wear on wiper blades as well as interference
with the rain sensor.<
Caring for the vehicle finish
Regular care helps your vehicle retain its value
and protects the paint from the long-term
effects of aggressive substances.Regionally occurring environmental factors can
affect and damage vehicle finish. It is therefore
important to tailor the frequency and extent of
your car care accordingly.
Immediately remove particularly aggressive
substances such as spilled fuel, oil, grease,
brake fluid, tree resin, or bird droppings; other-
wise, they may damage your paint.
Repairing paint damage
Repair stone damage or scratches imme-
diately, depending on the severity of the
damage, to prevent the formation of rust.<
BMW recommends having paint damage pro-
fessionally repaired using Genuine BMW finish
materials in accordance with factory guidelines.
Waxing
Sealant is required when w a t e r n o l o ng e r b e a ds
on the clean surface of the paint. Use only prod-
ucts that contain carnauba wax or synthetic wax
to seal your finish.
Rubber gaskets
Treat only with water or a rubber care product.
To avoid noise or damage, do not use
products that contain silicone to care for
rubber gaskets.<
Chrome components
Particularly after exposure to road salt, thor-
oughly cleanse parts like the radiator grille, door
handles, or window frames with plenty of water
with shampoo added to it. For additional treat-
ment, use chrome polish.
Alloy wheels
Depending on your system, braking can gener-
ate dust, which settles on the light-alloy wheels.
Remove this dust regularly with acid-free wheel
cleaner.
Do not use aggressive, acid-containing,
strongly alkaline, or coarse cleansers and
do not use steam cleaners at temperatures
greater than 1407/606; otherwise you may
damage your vehicle.<

Outside sensors
Sensors on the outside of the vehicle, such as
Park Distance Control sensors or radar sensors,
should be kept clean and free of ice to retain
their full function.
Interior care
Upholstery materials/cloth-covered
paneling
Clean regularly with a vacuum cleaner in order
to remove surface dirt.
In the event of more serious soiling such as bev-
erage stains, use a soft sponge or a lint-free
microfiber cloth in combination with suitable
interior cleaners. Follow the instructions on the
packaging.
Clean upholstery material over a large
area extending out to the seams. Avoid
intense friction.<
Open Velcro fasteners on pants or other
items of clothing can cause damage to
the seat covering. Make sure that the Velcro
fasteners are closed.<
Leather/leather-covered paneling
The leather used by BMW is a high quality
natural product. Slight patterns in the
grain are part of the typical properties of a natu-
ral leather.
Dust and dirt from the road chafe in pores and
folds and result in considerable wear and cause
the leather surface to become prematurely brit-
tle. We therefore suggest that you clean the
leather with a dust cloth or vacuum cleaner at
regular intervals.<
Particularly with light-colored leather, make
sure to clean it regularly since it has a greater
tendency to become soiled.
Treat the leather twice a year with a leather
lotion since dirt and grease harm the protective
layer of the leather.
Carpets/luggage compartment
Carpeting, floor mats, and luggage compart-
ment rugs and paneling can be cleaned with a
vacuum or in the event of more serious soiling,
cleansed with an interior cleaner.
Floor mats and luggage compartment rugs can
be removed for cleaning. When inserting into
place, make sure that the seat rails do not pro-
trude over the floor mats; otherwise floor mats
can be damaged.
Fluff on new floor mats is a result of the produc-
tion process and can be removed by repeated
vacuuming.
Plastic components inside
Clean the glass cover of the instrument panel,
imitation leather surfaces, lamp lenses, and
matte components with water and, if necessary,
a solvent-free plastic cleaner.
Fine wooden components
Use a damp cloth to clean fine wooden trim
panels and components. Follow up by drying
with a soft cloth.
Safety belts
Do not use cleansers to clean the safety
belts since this can destroy the web-
bing.<
Inside sensors
Clean inside sensors such as those of the high-
beam assistant using a lint-free cloth moist-
ened with glass cleaner.
Displays
Clean displays like the radio or the Control Dis-
play using a display-cleaning cloth or a soft,
nonabrasive lint-free cloth.
Avoid using excessive pressure when
cleaning displays; otherwise, you could
damage them.<
Never use chemical-based cleansers or
household scouring products. Keep all
liquids away from the equipment. Otherwise
