148nWinter 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 come on
when the parking brake is
applied. <
If there is a change in steering behavior,
for instance greater steering effort or if
steering becomes lighter as speed
increases in vehicles equipped with
Servotronic
*:
Contact your BMW center for an
inspection.
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 "LEVEL CONTROL
INACTIVE" 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 authorized BMW
center. Drive with appropriate caution
in the meantime. 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.

Adding coolant
Wait until the engine cools before
removing the cap from the expansion
tank. The needle of the coolant temper-
ature gauge in the instrument cluster
must be located in the blue zone; other-
wise, there is a danger of scalding.
1 Start by turning the cap counter-
clockwise. Pause to allow any
accumulated pressure to escape,
then open.
2 If the coolant is low, slowly add coolant until the correct level is
reached – do not overfill.
The coolant is a mixture of water and
extended-duty antifreeze with corrosion
inhibitor. Always maintain the pre-
scribed all-season 50:50 mixture ratio
for year-round protection against inter-
nal corrosion. No other additives are re-
quired.
Replace the coolant every four years.
If the indicator lamp for the
brake hydraulic system comes
on or if the "CHECK BRAKE
FLUID" warning appears in the
Check Control
*: the brake fluid
level is too low in the reservoir.
The brake fluid reservoir is located
under the microfilter housing on the
driver's side of the car. Should you de-
termine that the brake fluid is low, refer
the problem to your BMW center, who
can trace and rectify any sources of
leakage when refilling the reservoir.
Your BMW center is familiar with the
specifications for approved brake
fluids (DOT 4).
Brake fluid loss results in extended
pedal travel. For this situation, refer to
the notes on page 146.
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the safety and
reliability of the brake system, have
the brake fluid changed every two years
by an BMW center. Refer also to the
Service and Warranty Information
Booklet (US models) or to 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 which is out of reach of 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
environmental laws regulating the
disposal of brake fluid. <

171nCaring for your car
Washing your car
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.
> 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 which are inacces-
sible to the automatic washer – such as
door sills, door and hood edges, etc. –
should be cleaned by hand.
In the winter months, it is especially im-
portant 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 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 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. <

173nCaring for your car
Caring for the vehicle finish
Regular washing is a preventive mea-
sure against long-term effects from
substances that are harmful to the vehi-
cle's finish, especially if you drive your
vehicle in areas with high levels of air
pollution or aggressive natural sub-
stances (tree resins, pollen).
Nevertheless, you should immediately
remove especially aggressive sub-
stances. Failure to do so can lead to
changes in the paint's chemical struc-
ture or to discoloration. Gasoline spilled
during refueling, oil, grease and brake
fluid should always be cleaned away
immediately, as should bird droppings
(finish damage).
Any contamination remaining on the
surface of the vehicle will be especially
conspicuous after washing. Use clean-
ing fluid or alcohol with a clean cloth or
cotton pad to remove. Remove tar
spots with tar remover. After cleaning,
the affected areas should be waxed to
ensure continued protection.
Use cleaning and car-care
products that you can obtain
at your BMW center. <
Waxing your car
Protect the finish using carnauba or
synthetic-based waxes only.
The best way to determine when the
finish needs to be waxed is by noting
when water stops beading on the sur-
face.
You can use a glass cleaner to remove
any wax or silicone that may have been
left on the windows during waxing.
Use cleaning and car-care
products that you can obtain
at your BMW center. <
Paint damage
You can touch up small areas of dam-
age with BMW spray paint or a BMW
touch-up stick.
The paint color code for your vehicle is
provided on a sticker located on the
right hand side under the hood and on
the first page of your Service and War-
ranty Information Booklet.
Damage caused by flying stones,
scratches, etc., must be touched up
without delay to prevent rust from form-
ing.
If corrosion has started to form in an
area with paint damage, remove all rust
and clean the area. Then prime the area
with a BMW Primer Stick. Finally, apply
the finish coat. After a few days, polish
and protect the touched-in areas.
More extensive paint damage should
be repaired professionally in accor-
dance with the manufacturer's instruc-
tions. Your BMW center uses original
BMW finish materials in accordance
with approved repair procedures.
