Wheel and tire combinations The right choice Use only tires approved by BMW.
Refer to the information beginning on
page 129.
Due to the high speeds this vehicle can
reach, the use of specific brands, spec-
ifications and sizes is mandatory.
Consult any BMW center for details.
Comply with local/national regulations.
The correct wheel-tire combina-
tion affects different systems such
as ABS, ATC and ASC+T/DSC. The
function of these systems is impaired if
improper 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, for example, remount
the approved wheel-tire combination as
soon as possible.<
Codes on tires and wheels The tire codes will aid you in selecting
the correct tire.
Codes on radial tires:
The speed rating indicates the approved
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 187 mph (300 km/h)
ZR = over 150 mph (240 km/h) For 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)
205/60 R 15 91 W
Winter 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 tire valves from dirt by using
screw-on valve stem caps. Dirt in the
valves frequently leads to slow leaks. For example:
Rim width
in inches
Code letter for
flange type
Symbol for full-drop
center rim
Rim diameter in inches
Hump on the 2 rim shoulders
7 x 15 H 2

Winter tiresChoosing the right tireBMW recommends winter tires (M+S
radial tires) for driving in adverse winter
road conditions. So-called all-season
tires with the M+S-identification mark
do indeed possess better winter trac-
tion than summer tires with the load
rating H, V, W, Y und ZR, but usually do
not achieve the same level of perfor-
mance as 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 on the best winter tires for
your particular driving conditions.
Do not exceed specified
maximum speeds
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 pressureOnce the tire wears to below 0.16 in
(4 mm), winter tires display a percep-
tible decrease in their ability to cope
with winter driving conditions, and
should be replaced in the interest of
safety.
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.
StorageAlways store tires in a cool, dry place.
Store them away from light whenever
possible. Protect the tires against
contact with oil, grease and fuel.Snow chains
*
The use of narrow-link BMW snow
chains on summer or winter tires is
approved only in pairs and only on the
rear wheels. Comply with all manufac-
turer's safety precautions when
mounting the chains.
BMW 325xi: in a worst-case scenario,
i.e. if your vehicle is stuck on one side
or you cannot access one tire, then only
one chain may be attached to a rear
wheel for a short period of time.
Comply with all manufacturer's safety
precautions when mounting the chains.

Coolant Brake fluidAdding coolant Wait until the engine cools before
removing the cap from the expansion
tank. The needle of the coolant gauge
in the instrument cluster must be
located in the blue zone. If it is not,
there is a danger of scalding.
1 Turn the cap slightly counterclock-
wise in order to allow accumulated
pressure to escape, then open.
2 If the coolant is low, slowly add
coolant until the correct level is
reached Ð do not overfill.
The coolant is a mixture of water and
extended-duty antifreeze with corrosion
inhibitor. Always maintain the
prescribed all-season 50:50 mixture
ratio for year-round protection against
internal corrosion. No other additives
are required.
Replace the coolant every four years.If the brake warning lamp comes on
and the parking brake has been
released:
Check the brake fluid level. Fill it to the
top mark ("MAX") if necessary.
For adding brake fluid or for deter-
mining and correcting the cause of
brake fluid loss, consult your BMW
center. Your BMW center is familiar
with the specifications for factory-
approved brake fluids (DOT 4).
Brake fluid loss can result in extended
pedal travel. Comply with the informa-
tion provided on page 120.
460de128
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the safety and reli-
ability of the brake system, have the
brake fluid changed every two years by
a BMW center. Refer also to the Service
and Warranty Information Booklet
(US models) or the Warranty and
Service Guide Booklet (Canadian
models).
Brake fluid is toxic and damages the
vehicle's paint. You should always store
it in its original container and in a loca-
tion inaccessible to children.
Do not spill the fluid and do not fill the
brake fluid reservoir beyond the "MAX"
mark. The brake fluid could ignite upon
contact with hot engine parts and cause
serious burns.<
Comply with the applicable envi-
ronmental laws regulating the
disposal of brake fluid.<

Washing your vehicle You can wash your BMW at an auto-
matic car wash, even when it is new.
Brushless systems are preferable.
Wipe away tough dirt and loosen and
remove dead insects before washing
the vehicle.
In order to avoid spots, do not wash
the vehicle when the hood is warm, or
during or immediately after 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 to vehicles
with attached body accessories (such
as spoilers or antennas). Consult the
car wash operator if necessary.
>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
can cause malfunctions in the function
of the rain sensor.Turn the rain sensor off (refer to
page 69) when passing through an
automatic car wash. Failure to do so
could result in damage caused by unin-
tended wiper activation.<
Parts of the vehicle 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
important to ensure that the vehicle is
washed on a regular basis. Large quan-
tities of dirt and road salt are difficult to
remove, and they also damage the
vehicle.
If spray wands or high-pressure
washers are used, be sure to
maintain an adequate distance between
the spray source and the vehicle's
surface. Inadequate distance and
excessive pressure can damage or
weaken the finish, making it more
susceptible to subsequent attack. In
addition, moisture could penetrate to
vehicle components, 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 abrasives 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 a scraper.<
After washing the vehicle, apply
the brakes briefly to dry them.
Braking efficiency might otherwise be
reduced by the moisture and the brake
rotors could be corrode.<
Caring for your vehicle

Caring for your vehicleExterior finish To provide effective corrosion protec-
tion, multilayer paintwork is applied at
the factory. Cataphoretic immersion
priming techniques are supplemented
with special body-cavity protectants,
by applying specially-developed and
extensively tested materials.
A layer of flexible PVC is first applied
to the undercarriage. Following this,
a comprehensive undercoating treat-
ment with a wax-based protectant is
applied. Regular maintenance makes
an important contribution to maintaining
the safety and value of your vehicle.
Increasing awareness of the effects of
harmful environmental factors on vehi-
cle finishes have led paint and vehicle
manufacturers to initiate programs
designed to further improve the durabil-
ity of their finishes. Despite this, envi-
ronmental factors that occur locally or
regionally can have negative effects on
the finish of your vehicle. Use the
factors to determine the frequency and
extent of your efforts to maintain the
vehicle finish.Depending upon material and type of
impact (perforation of paint layer),
physical stresses from sand, road salt,
gravel, etc., can cause corrosion to start
extending beneath the finish, starting at
the point of impact.
Road dirt, tar spots, dead insects,
animal droppings (strong alkali effect)
and tree excretions (resins and pollen)
all contain substances capable of
causing damage when allowed to
remain on the finish of your vehicle for
any extended period of time (spots,
etching, flaking, separation in the top
coat).
In industrial areas, flue dust deposits,
lime, oily soot, precipitation containing
sulfur-dioxide (acid rain) and other envi-
ronmental pollutants will damage the
vehicle's finish unless adequate care is
provided Ð even though this is generally
limited to the outside horizontal sur-
faces.In coastal regions, high levels of
atmospheric salt and humidity promote
corrosion.
In tropical zones, temperatures of over
+105 7 (+40 6) in the shade prevail,
in addition to heavy ultraviolet radiation
and high humidity. Under those condi-
tions, light paints can reach tempera-
tures up to +175 7 (+80 6) and dark
paints up to +250 7 (+120 6).

Caring for your vehicleCaring for the windowsYou 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.
Clean the wiper blades with soapy
water. The wiper blades should be
replaced twice a year Ð before and after
winter. This is especially important for
vehicles with a rain sensor.
Use only wiper blades approved
by BMW.<
Caring for other vehicle
components and materials Light-alloy wheels should be treated
with alloy wheel cleaner, especially
during the winter months. However, do
not use aggressive products contain-
ing acids, strong alkalis or abrasives.
Do not use steam cleaners operating at
temperatures above +140 7 (+60 6).
Follow the manufacturer's instructions.
If your vehicle has chrome parts
*, such
as the window frames and door
handles, be especially careful about
cleaning them with plenty of water and
possibly a shampoo supplement as well
after the roads have been salted.
Use a chrome polish for an additional
treatment.
Plastic components, vinyl upholstery,
headliners, lamp lenses, the clear cover
of the instrument cluster and compo-
nents with a sprayed dull black surface
can be cleaned with water and a
synthetic cleaner (if necessary). Do not
allow moisture to soak through the
seats or headliner. Never use solvents
such as lacquer thinner, heavy-duty
grease remover, fuels, or similar
substances. Rubber components should be cleaned
with water only; a rubber treatment or
silicone spray may also be applied.
Safety belts should be cleaned with a
mild soap and water solution without
being removed from the car. Never
attempt 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.
Use only a damp cloth to clean trim
panels made of real wood
* and other
parts constructed of real wood
*. Follow
up by drying with a soft cloth.
Use the cleaning and car-care
products available at your BMW
center.<

Caring for your vehicleCare of upholstery materials Depressions in the upholstery that
result from everyday use can be
brushed smooth by brushing against
the nap with a lightly dampened brush.
The tendency of the pile to lie in a
particular direction on velour upholstery
is not a quality defect, and, just as on
home textiles or clothing, cannot be
avoided.
Lint on upholstery materials, textile or
leather remnants that have been worn
into the upholstery may be removed
with a lint brush or a Velcro
â brush. A
cleaning glove is available for especially
"stubborn" lint. Stains and fairly large
areas of dirt should be cleaned off with-
out delay, using lukewarm water and an
interior cleaner, stain remover or appro-
priate cleaning fluid. Brush the fabric
afterwards to restore its appearance.
If the vehicle is to be stored for an ex-
tended period, or if it is exposed to in-
tense sunlight, cover all the seats or the
windows to prevent fading.
Use the cleaning and car-care
products available at your BMW
center.<
The buildup of an electrostatic charge
on the seat covers, particularly if
atmospheric humidity is low, can give
the occupants an unpleasant electric
shock if they touch metal body parts
after leaving the vehicle. Although this is
not dangerous in any way, it can be
avoided by touching a bare or polished
metal part of the vehicle while getting
out.
Leather care The leather
* upholstery used by BMW
is a natural product of the highest
quality, processed using state-of-the-
art methods to ensure that it will main-
tain its high quality for years to come,
provided that it is properly cared for.
Because this product is manufactured
using natural materials, you must make
allowance for its special characteristics
and for the peculiarities of its use
and care.
Regular periodic cleaning and care
are essential, as dust and road dirt act
as abrasives in the pores and creases
of the material. This leads to wear
spots and premature brittleness on
the surface of the leather. We there-
fore suggest that you clean the leather
with a vacuum cleaner or cloth at
frequent intervals.
For cleaning, use BMW leather
cleaning foam.
Since dirt and grease gradually attack
the protective layer of the leather, the
cleaned surfaces should be treated
with BMW leather care agent. This also
acts as an antistatic agent.
For protection against dampness
or moisture, treat the leather with an
impregnating agent made by BMW.
