Winter operation Power steering Level control system
*
Skid control Release the accelerator pedal and
depress the clutch pedal. Countersteer
carefully and attempt to regain control
of the vehicle.Parking Engage 1st or reverse gear. If your
vehicle is equipped with an automatic
transmission, place the selector lever in
"Park." On vehicles with manual trans-
mission, also apply the parking brake
when parking on inclined surfaces. In
order to prevent the parking brake pads
from locking due to frost or corrosion,
dry them by gently applying the parking
brake as the vehicle is coming to a
stop. Make sure that following traffic is
not endangered.
The brake lamps do not light up
when the parking brake is
applied.<
If there is a change in steering response
(difficult steering, for example) or, espe-
cially on vehicles with Servotronic
*, if
the steering "drifts" or "floats" at
increasing speeds:
Have your BMW center inspect this
system as soon as possible.
If the power steering fails,
increased effort will be required to
steer the vehicle.<
The warning lamp for the level
control system comes on, or the
message SELFLEVEL
SUSP.INACT appears in the Check
Control: There is a malfunction in the
level control system.
Stop and inspect the vehicle. If it is
riding significantly lower in the rear than
in the front, or if it is sitting at an incline
(left rear compared to right rear),
consult the nearest BMW center. Drive
with appropriate caution in the mean-
time, especially if you are driving under
poor road-surface conditions. The
vehicle has reduced ground clearance
or driving comfort is noticeably
reduced.
Even if the attitude of the vehicle is
normal, you should consult the nearest
BMW center if the warning lamp indi-
cates a system fault.

Wheel and tire combinationsThe right choice
Use only wheels and tires
approved by BMW for the corre-
sponding vehicle model, as otherwise
the tires may make contact with the
body as the result of tolerances despite
the same nominal size being used,
resulting in serious accidents. If non-
approved wheels and tires are used,
BMW cannot evaluate their suitability,
and therefore cannot be held liable for
driving safety.<
For wheel and tire specifications
approved by BMW, refer to page 150.
The correct wheel-tire combina-
tion affects different systems such
as ABS, ATC and 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 on the
vehicle and, for example, restore the
approved wheel-tire combination
following a flat tire as soon as
possible.<
Codes on the tires and wheels The code on tires has the following
meaning.
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 186 mph (300 km/h)
ZR= over 150 mph (240 km/h) Example:
Nominal width
in mm
Aspect ratio in X
Belt rating code for
radial tires
Rim diameter in inches
Load rating
(not on ZR tires)
Speed rating
(before R on ZR tires)
235/65 R 17 104 H
All-season, all-terrain and 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 on light-alloy wheels:
Protect valve stems and valves from dirt
using screw-on valve stem caps. Dirt in
the valves frequently leads to slow
leaks. Storage Store tires in a cool, dry place,
protecting them against light when-
ever possible. Protect the tires against
contact with oil, grease and fuel. Example:
Rim width
in inches
Code letter for
flange type
Symbol for full-drop
center rim
Rim diameter in inches

Approved wheel and tire specifications Observe the specifications for tires and
wheels in the vehicle's documents. If
sizes not approved by the manufacturer
are mounted, an entry in the vehicle's
documents may be necessary. Snow chains
*
It is only possible to mount snow
chains on the rear wheels with tire
size 235/65 R 17. BMW tests certain tire brands for each tire size, classifies them as road-safe and
approves them. Consult your BMW center for more information.
Observe any regulations applicable in the country of use, e.g. requiring entry in
the vehicle documents.

The use of rims and lug bolts that
do not meet the specifications of
the original factory-installed equipment
will affect the safe operation of your
vehicle and may cause an accident and
personal injury.
Never mix tires of different design, such
as steel-belted radials with radial bias
belted or bias-ply tires, etc. Mixing tire
types will adversely affect roadholding
and can lead to loss of vehicle
control.<

Caring for your vehicleWashing your vehicle You 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 vehicle.
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.
Before washing the vehicle in a
car wash, fold in the exterior
mirrors manually, otherwise they may
be damaged on account of the width of
the 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.
Deactivate the rain sensor in auto-
matic car washes. If you do not,
damage may occur if the wipers switch
on unintentionally.<
Parts of the vehicle that are inacces-
sible to the automatic car wash — such
as door sills, door and hood edges, etc.
— 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 cause damage to
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 wipe dry (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 – 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 also be corroded.<

Caring for your vehicleExterior finish To provide effective corrosion protec-
tion, multilayer paintwork is applied
at the factory. Cataphoretic immersion
priming techniques are supplemented
using special body-cavity protectants,
with the application of specially-devel-
oped 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 impor-
tant contribution to maintaining the
safety and value of your vehicle.
Increasing awareness of the effects of
harmful environmental factors on
vehicle finishes have led paint and
vehicle manufacturers to initiate
ongoing programs designed to further
improve the durability of their finishes.
Despite this, environmental factors that
occur locally or regionally can have
negative effects on the finish of your
vehicle. These should guide you in
determining 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 period of time (spots, etching,
flaking, separation in the top coat).
In industrial areas, deposits from fly
ash, lime, oil deposits, sulfur-dioxide in
precipitation (acid rain) and other envi-
ronmental pollutants will all damage the
surface of the vehicle unless adequate
protection is provided.In coastal regions, high levels of atmo-
spheric 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 vehicleWindow care You 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, before and after
the cold season.
Use only wiper blades that have
been approved by BMW.<
Caring for other vehicle
components and materialsLight-alloy wheels should be treated
with alloy wheel cleaner, especially
during the winter months. However, do
not use aggressive products containing
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 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 chrome polish as 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 (add plastic
cleaner as required). Do not allow mois-
ture to soak through the seats or head-
liner. Never use solvents such as
lacquer 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 vehicle. 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
prevent 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.

Caring for your vehicleLeather 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
as well as 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 therefore
suggest that you clean the leather with
a vacuum cleaner or dust cloth at
frequent intervals.
For cleaning use BMW leather cleaning
foam.
Since dirt and grease gradually affect
the protective surface layer of the
leather, the cleaned surfaces should be
treated with a BMW leather care agent.
This also acts as an antistatic agent. For protection against dampness or
moisture, treat the leather with a BMW
impregnating agent.
We recommend that you perform this
procedure twice a year on leather
exposed to normal use.
Spills should be wiped up immediately.
Remove grease and oil stains without
rubbing, but rather by dabbing with
spot remover.
If the upholstery is to be exposed to
intense sunlight or if the vehicle is to be
stored for an extended period, cover all
leather surfaces (or, better yet, the
windows) to prevent fading.
A full range of car-care products is
available from your BMW center.<
Cleaning agents can contain
substances that are dangerous or
pose health risks. For this reason,
always read and comply with the warn-
ings and danger notices on the
package.
Open the doors or windows on your
vehicle before cleaning the interior.
Never clean your vehicle with cleaning
agents (or solvents) not specifically
intended for this purpose.<

Any BMW center will be glad to inform
you of the advisability, legal require-
ments and factory recommendations
with regard to technical modifications
on the vehicle. For this purpose, the
BMW center will require the Vehicle
Identification Number and, in some
cases, also the engine number.
Light-Emitting Diodes (LEDs) Light-emitting diodes installed behind
translucent lenses serve as the light
source for many of the controls and
displays in your vehicle. The concept
behind their operation is related to that
employed for lasers, and they are
formally designated as Class 1 light-
emitting diodes.
Do not remove the protective lens
and avoid staring directly at the
unfiltered beam for extended periods
(several hours), as inflammation of the
iris could result.<
California laws require us to state the
following warning:
Engine exhaust, some of its
constituents, and certain vehicle
components contain or emit chemicals
known to the State of California to
cause cancer and birth defects or other
reproductive harm.<

OBD interface socket The Onboard Diagnostic (OBD) inter-
face socket is located on the left of the
driver's side at the bottom of the instru-
ment panel and under a cover.
The cover has the letters "OBD" on it.
The purpose of the OBD system is to
ensure proper operation of the emis-
sion control system for the vehicle's
lifetime. The system monitors emission-
related components and systems for
deterioration and malfunction.530us105
An illuminated lamp informs you
of the need for service, not of
the need to stop the vehicle.
However, the systems should be
checked by your BMW center at the
earliest possible opportunity.
Under certain conditions, the indicator
will blink or flash. This indicates a rather
severe level of engine misfire. When
this occurs, you should reduce speed
and consult the nearest BMW center as
soon as possible. Severe engine misfire
over only a short period of time can
seriously damage emission control
components, especially the catalytic
converter.
Service Engine Soon warning

When the filler cap is not properly
tightened, the OBD system can
detect the vapor leak and the indicator
will light up. If the filler cap is subse-
quently tightened, the indicator should
go out within a few days.<

Lamps and bulbsXenon lamps
*
The operating life of these lamp units is
extremely long and the likelihood of
failure very low, provided that they are
not switched on and off a very great
number of times. If one of these bulbs
should nevertheless fail, it is possible to
continue driving with great caution
using the fog lamps, provided traffic
laws in your area do not prohibit this.
Because of the extremely high
voltages involved, any work on the
xenon lighting system should be carried
out by technically-qualified personnel
only. Failure to comply with this creates
a risk of fatal injury.< Turn signal indicators/Side lamps
