Wheels and tires
Mobility
Recommended tire brands
Certain makes of tire are recommended by
BMW for each tire size. They are marked with a
clearly visible BMW designation on the sidewall
of the tire.
When properly used, these tires meet the high-
est standards in terms of safety and handling
characteristics.
Special characteristics of winter tires
BMW recommends winter tires for driving on
winter roads or at temperatures below +45
7/
+7 6. Although all-season M+S tires provide
better winter traction th an summer tires, they
generally fail to provide the same levels of cold-
weather performance as winter tires.
Pay attention to speed
Always comply with the speed limit for the
winter tires mounted on your car; failure
to do so could result in tire damage and
accidents. <
If the car is capable of speeds higher than that
permitted for the winter ti res, a label stating the
maximum permitted speed for the mounted
tires must be displayed in your field of view.
Specialist tire dealers and your BMW center
can supply these labels.
Storage
Always store wheels and tires in a cool, dry
place with as little exposure to light as possible.
Always protect tires agains t all contact with oil,
grease and fuels. Do not exceed the maximum
tire inflation pressure indicated on the sidewall
of the tire.
Swapping wheels between axles
BMW advises against swapping wheels
between the front and rear axles, even if all tires
have the same size, as th is could impair driving
characteristics. If the tires are of mixed sizes,
swapping wheels between the axles is not
permissible.
Run-flat tires
The symbol identifying run- flat tires is a circle
with the letters RSC on the sidewall.
Run-flat tires comprise a conditionally self-
supporting tire and a special rim. The reinforce-
ment in the sidewalls en sures that the tire can
continue to be used su bject to certain restric-
tions, even if depressurized.
For information on continuing to drive with a flat
tire, refer to Indication of a flat tire, page 101.

Vehicle equipment
In this chapter, all pr oduction, country, and
optional equipment that is offered in the model
range is described. For this reason, descrip-
tions will be given of some equipment that may
not be available in a vehi cle, for example due to
the special options or national-market version
selected. This also app lies to safety related
functions and systems.
Washing the vehicle
Notes
When using steam cleaners or high-pres-
sure cleaning jets, ma ke sure to maintain
a sufficient distance and stay below a maximum
temperature of 140 °F/60 6.
Too close a distance, too high a pressure, or too
high a temperature may cause damage or pre-
liminary damage that can then lead to long-term
damage.
Follow the operating instructions for the steam
jet or high-pressure washer. <
When using high-pressure washers, do
not spray the sensors, e.g. of the Park
Distance Control, for an extended period and
maintain a distance of at least 1 ft/30 cm from
them. <
Regularly remove foreign objects, e.g. leaves, in
the vicinity of the windshield when the hood is
open.
Wash the vehicle more frequently, particularly
in winter.
Heavy soiling and road salt can lead to vehicle
damage.
Automatic car washes
Notes
In car washes with high pressures and
nozzle positions, wate r may drip into the
vehicle around the windows. <
Please note the following:
> Give preference to car washes that use
cloth or soft brushes in order to avoid paint
damage.
> Wheels and tires must not be damaged by
transport devices.
> Fold in exterior mirror, refer to page 55; oth-
erwise, they can be damaged due to the
width of the vehicle.
> Deactivate the rain sensor, refer to page 73,
to prevent undesired wiper operation.
> Remove additional add-on parts, e.g. spoil-
ers or phone antennas, if they could be
damaged.
> Unscrew the rod antenna.
> Leave the remote control in the ignition
lock.
Avoid car washes with guide rail heights
over 4 in/10 cm, otherwise there is
danger of damaging chassis parts. <
Convertible: retractable hardtop
Proceed as you would in a normal car wash.
When you open a wet hardtop, water
drops may run into the trunk. If necessary,
remove items from the trunk beforehand to
avoid water stains or soiling. <
