Tire rotation Wheel and tire combinationsShould you decide to rotate the tires, it
is essential to comply with the follow-
ing: Rotate tires on the same side only,
since braking characteristics and road
grip could otherwise be adversely
affected.
Following tire rotation, correct the tire
inflation pressure.
If different tire sizes are mounted
on the front and rear axles (refer to
page 140), the wheels may not be
rotated from one axle to the other.<
The right choiceUse only tires approved by BMW.
Refer to the information beginning on
page 140.
Because of the high speeds this vehicle
can reach, the use of specific tire
brands, specifications and dimensions
is mandatory. Consult any BMW center
for details.
Comply with national, state, or province
regulations.
The correct wheel-tire combina-
tion affects different systems such
as ABS, ATC, ASC+T/DSC. The func-
tion of these systems is impaired if im-
proper wheel-tire combinations are
used.
For this reason, use only tires of the
same brand and tread pattern. In the
event of a flat tire if you have mounted
winter tires, for example, remount the
approved wheel-tire combination as
soon as possible.<
Codes on tires and wheelsThe tire codes will aid you in selecting
the correct tire.
Codes on radial tires:
The speed rating indicates the ap-
proved maximum speed for the tire.
Summer tires:
S = up to 112 mph (180 km/h)
T = up to 118 mph (190 km/h)
H = up to 130 mph (210 km/h)
V = up to 150 mph (240 km/h)
W = up to 167 mph (270 km/h)
Y = up to 186 mph (300 km/h)
ZR= over 150 mph (240 km/h)Example:
Nominal width
in mm
Aspect ratio in %
Radial tire code
Rim diameter in inches
Load rating
(not on ZR tires)
Speed rating
(before R on ZR tires)

Wheel and tire combinations Winter tiresWinter tires:
Q M+S = up to 100 mph (160 km/h)
T M+S = up to 118 mph (190 km/h)
H M+S = up to 130 mph (210 km/h)
Codes stamped on light-alloy wheels:
Protect valve inserts against dirt using
screw-on valve stem caps. Dirt in the
valves frequently leads to slow leaks. Example:
Rim width

Code letter for
flange type
Symbol for full-drop

Choosing the right tireBMW recommends winter tires (M+S
radial tires) for driving in adverse winter
road conditions. While tires known as
all-season tires (M+S designation) pro-
vide better winter traction than summer
tires with load ratings H, V, W, Y and
ZR, they generally do not achieve the
performance of winter tires.
In the interests of safe tracking and
steering response, install radial tires
made by the same manufacturer and
with the same tread configuration on all
four wheels if you elect to mount winter
tires.
Mount only winter tires which have
been approved by BMW. Any BMW
center will be glad to provide you with
information for selecting the best winter
tires for your particular driving condi-
tions.

Never exceed the maximum
speed for which the tires are
rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by skilled
professionals only. Any BMW center
has the required technical knowledge
and the proper equipment and will be
happy to assist you.<
Tire condition, tire pressureWinter tires display a perceptible loss in
their ability to cope with winter driving
conditions once the tread wears to be-
low 0.16 inches (4 mm), and should
thus be replaced.
Comply with the specified tire inflation
pressures Ð and be sure to have the
wheel and tire assemblies balanced
every time you change the tires.
StorageStore tires in a cool, dry place, away
from light whenever possible. Protect
the tires against contact with oil, grease
and fuel.Use narrow-link BMW snow chains
on
summer or winter tires only in pairs and
only on the rear wheels. Comply with all
manufacturer's safety precautions when
mounting the chains.
It is not possible to mount snow
chains on tires with 17-inch
wheels.<

Caring for your carWashing your carYou can have your new BMW washed
in an automatic car wash. Car wash
systems that do not employ brushes are
preferable.
Wipe away tough dirt and loosen and
remove dead insects before washing
the car.
To prevent spots, avoid washing when
the hood is still warm, or immediately
after and during exposure to strong
sunlight.
When using an automatic car wash, be
sure that:
>The car wash system is suited for the
dimensions of your vehicle
>No damage will occur on vehicles
with attached body accessories (such
as spoilers or antennas). If you are
uncertain, consult the manager of the
car wash
>The wheels and tires of your vehicle
cannot be damaged by the convey-
ance devices of the car wash system
>The vehicle is cleaned with minimum
brush pressure, and that ample water
is available for washing and rinsing.Vehicles with rain sensor
*:
Clean the windshield regularly. Wax
from automatic car washes or insects,
for example, can cause malfunctions in
the function of the rain sensor.
Turn the rain sensor off in auto-
matic car washes. If you do not,
damage may occur if the wipers switch
on unintentionally.<
Parts of the car which are inaccessible
to the automatic washer Ð such as door
sills, door and hood edges, etc. Ð
should be cleaned by hand.
In the winter months, it is especially im-
portant to ensure that the car is washed
on a regular basis. Large quantities of
dirt and road salt are difficult to remove,
and they also cause damage to the ve-
hicle.
If spray wands or high-pressure
washers are used, be sure to
maintain an adequate distance between
the spray source and the vehicle's sur-
face. Inadequate distance and exces-
sive pressure can damage or weaken
the finish, making it more susceptible to
subsequent attack. In addition, mois-
ture could penetrate to vehicle compo-
nents, leading to long-term damage.<
When cleaning the headlamps,
please observe the following:
>Do not clean by wiping with a dry
cloth (scratches). Never use abra-
sives or strong solvents to clean the
covers
>Remove dirt and contamination
(such as insects) by soaking with
BMW Car Shampoo and then rinsing
with plenty of water
>Always use a deicer spray to remove
accumulated ice and snow Ð never
use an ice scraper.<
After washing the car, apply the
brakes briefly to dry them. Braking
efficiency might otherwise be reduced
by the moisture, and the brake rotors
could also be corroded.<

158n
Caring for your carWindow careYou can use window and glass cleaner
to clean inside window surfaces and
mirrors without smearing and streaking.
Never use polishing pastes or abrasive
(quartz) cleansers on mirror lenses.
When caring for break-resistant
security glass
*, observe the fol-
lowing instructions:
The inner surface of the side windows
is coated with a plastic film. For this
reason, do not affix any decals or adhe-
sive stickers on the inside of these win-
dows unless they are to be placed there
permanently.
Wash the glass with clean water. If nec-
essary, you may add a commercially-
available mild household cleaner. Do
not use abrasive cleaners.
If the windows are fogged or iced over,
treat them with an anti-misting cloth or
a deicer spray Ð do not use an ice
scraper.<
Clean the wiper blades with soapy wa-
ter. The wiper blades should be re-
placed twice a year, before and after
the cold season.
Use only wiper blades which have
been approved by BMW.<
Caring for other vehicle
components and materialsLight-alloy wheels should be treated
with alloy wheel cleaner, especially dur-
ing the winter months. However, do not
use aggressive products containing ac-
ids, strong alkalis or abrasives. Do not
use steam cleaners operating at tem-
peratures above 1407 (606). Follow
the manufacturer's instructions.
If your vehicle has chrome parts
* such
as window moldings, door handles or
other items, clean these parts carefully
with ample clean water, especially if
they have an accumulation of road salt.
Use a chrome polish for an additional
treatment.
Plastic components, vinyl upholstery,
headliners, lamp lenses, the clear cover
of the instrument panel and compo-
nents with a sprayed dull black surface
can be cleaned with water (add plastic
cleaner as required). Do not allow mois-
ture to soak through the seats or head-
liner. Never use solvents such as lac-
quer thinner, heavy-duty grease
remover, fuels, etc.Rubber components should be cleaned
with water only; a rubber treatment or
silicone spray may also be applied.
The safety belts should be cleaned with
a mild soap and water solution without
being removed from the car. Never at-
tempt chemical or dry cleaning, as
damage to the belt fabric could result.
After cleaning, never allow the inertia
reel to retract the belts until they are
completely dry. Dirty safety belts pre-
vent the inertia reel mechanism from
retracting the strap properly, and thus
constitute a safety hazard.
Heavily soiled floor carpets and mats
*
can be cleaned with an interior cleaner.
The floor mats can be removed from the
vehicle for cleaning.
Please use only a damp cloth to clean
wooden fascia panels and components.
Follow up by drying with a soft cloth.
Use cleaning and car-care
products that you can obtain
at your BMW center.<

Important safety notices
Do not attempt to remove the gas
generators of the airbag restraint
system from the vehicle. Have testing
and service procedures performed by
specially-qualified technicians only. In
the event of a malfunction, deactivation,
or triggered actuation (as a response to
an accident) of the airbag restraint sys-
tem, consult your authorized BMW cen-
ter for repairs or service operations.

Modifications may not be made on ei-
ther the wiring or the individual compo-
nents in the airbag system. These in-
clude the padded steering wheel hub,
the instrument panel, the side trim pan-
els of the front or rear doors and the
roof pillars or the sides of the headliner.
Never apply adhesive materials to these
components or cover or modify them in
any way. Do not attempt to remove or
dismantle the steering wheel.
To ensure compliance with official
safety regulations, entrust disposal of
airbag generators to an authorized
BMW center.
Unprofessional attempts to service the
system could lead to failure in an emer-
gency or undesired airbag activation,
either of which could result in personal
injury.< Consult your BMW center regarding the
required special procedures if you in-
tend to store the vehicle for longer than
three months.

Changing tires
Safety measures in the event of a
flat tire or wheel change:
Stop the vehicle as far as possible from
passing traffic. Park on a firm, flat,
surface. Switch on the hazard flashers.
Turn the steering wheel to the straight-
ahead position, remove the key and
engage the steering lock. Shift into 1st
or reverse (selector lever in Park with
automatic transmission) and engage the
parking brake. All passengers should
be outside the car and well away from
your immediate working area (behind a
guardrail, for instance).
If a warning triangle or portable hazard
warning lamp is available, set it up on
the roadside at an appropriate distance
from the rear of the vehicle. Comply
with all safety guidelines and regula-
tions.
Change the wheel only on a level, firm
surface which is not slippery. Avoid
jacking the car on a soft or slippery sup-
port surface (snow, ice, loose gravel,
etc.), since it could slide sideways.
Position the jack on a firm support
surface.
Do not place wooden blocks or similar
objects under the jack. If this is done,
the jack might not be able to reach its
full support capacity because of the
limited height.
Do not lie under the vehicle or start the
engine when the vehicle is supported
by the jack Ð risk of fatal injury.<
What you will needIn order to avoid rattling noises later,
note the position of the tools when you
remove them and return them to their
original position when you are through
using them.
