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.<

Caring for your carExterior finishTo 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 treatment
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), phys-
ical 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 car 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 car unless adequate pro-
tection is provided.In coastal regions, high levels of
atmospheric salt and humidity promote
corrosion.
In tropical zones, temperatures of over
1057 (406) in the shade prevail, in
addition to heavy ultraviolet radiation
and high humidity. Under those circum-
stances, light exterior finishes reach
temperatures of up to 1757 (806)
and dark finishes up to 2507 (1206).

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.<

Caring for your carLeather careThe 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.
Use cleaning and car-care
products that you can obtain
at your BMW center.<
Cleaning agents can contain sub-
stances that are dangerous or
pose health risks. Therefore, always
comply with the warnings and danger
notices on the package.
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 car. For this purpose, the
center requires the Vehicle Identifica-
tion 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 offi-
cially 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.<
