Winter tires Snow chains
*
Choosing the right tire BMW recommends special winter tires
(M+S radial tires) for driving in adverse
winter road conditions. While the All-
Season tires with M+S designation that
are mounted as standard equipment
provide better winter traction than sum-
mer tires, they generally do not achieve
the performance of winter tires.
For safe tracking and steering re-
sponse, install winter tires made by the
same manufacturer having the same
tread configuration on all four wheels.
Mount only winter tires approved by
BMW. Any BMW center will be glad to
provide you with information for select-
ing the best winter tires for your partic-
ular driving conditions.
Do not exceed specified
maximum speeds
Never exceed the maximum
speed for which winter 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 pressure Once winter tires wear to a tread depth
below 0.16 in (4 mm), their performance
under winter driving conditions deterio-
rates noticeably. Worn tires should
therefore be replaced for safety consid-
erations.
Comply with the specified tire inflation
pressures Ñ and be sure to have the
wheel and tire assemblies balanced
every time you change the tires. Storage Store tires in a cool, dry place, away
from light whenever possible. Protect
the tires against contact with oil, grease
and fuel.
The use of narrow-link BMW snow
chains is approved only in pairs on the
rear wheels and only with tire size
235/65 R 17. Comply with all manufac-
turer's safety precautions when mount-
ing the chains.

Approved wheel and tire specifications Observe the specifications for tires and
wheels in the vehicle's manuals. If sizes
not approved by the manufacturer are
mounted, an entry in the vehicle's doc-
uments may be necessary. Snow chains

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 ve-
hicle 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 con-
trol.<

Caring for your vehicle Washing 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 mir-
rors 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.
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 vehicle that are inaccessi-
ble to the automatic washer Ñ such as
door sills, door and hood edges, etc. Ñ
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 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. 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 also be corroded.<

Caring for your vehicle Exterior 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 vehi-
cle finishes have led paint and vehicle
manufacturers to initiate ongoing pro-
grams 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 fre-
quency 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, start-
ing at the point of impact.
Road dirt, tar spots, dead insects, ani-
mal 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 cor-
rosion.
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).
146n
Caring for your vehicle Window 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 wa-
ter. The wiper blades should be re-
placed 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 materials Light-alloy wheels should be treated
with alloy wheel cleaner, especially dur-
ing 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 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 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 pre-
vent the inertia reel mechanism from re-
tracting 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 vehicle Leather care The leather upholstery
* used by BMW
is a natural product of the highest qual-
ity, processed using state-of-the-art
methods to ensure that it will maintain
its high quality for years to come, pro-
vided 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 sur-
face of the leather. We therefore sug-
gest that you clean the leather with a
vacuum cleaner or dust cloth at fre-
quent 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 ex-
posed 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 in-
tense sunlight or if the vehicle is to be
stored for an extended period, cover all
leather surfaces (or, better yet, the win-
dows) to prevent fading.
A full range of car-care products is
available from your BMW center.<
Cleaning agents can contain sub-
stances that are dangerous or
pose health risks. For this reason, al-
ways read and comply with the warn-
ings and danger notices on the pack-
age.
Open the doors or windows on your ve-
hicle before cleaning the interior. Never
clean your vehicle with cleaning agents
(or solvents) not specifically intended
for this purpose.<

Any authorized BMW center will be glad
to inform you of the advisability, legal
requirements and factory recommenda-
tions with regard to technical modifica-
tions 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 dis-
plays in your vehicle. The concept be-
hind their operation is related to that
employed for lasers, and they are for-
mally designated as Class 1 light-emit-
ting 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.<

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.
Warning lamp, Service Engine
Soon for Canadian models.
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.<
