Washing your vehicle You can have your BMW washed in
an automatic car wash, even when it
is new. Car wash systems that do not
employ brushes are preferable, refer to
page 157.
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 on 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.
Deactivate the rain sensor when
going through car washes (refer to
page 77) Ñ otherwise, the wipers could
be damaged if they inadvertently start
working.<
Parts of the vehicle that are inaccessi-
ble 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 be sure 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 sur-
face. Inadequate distance and exces-
sive 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 with a 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 also be corroded.<
Caring for your vehicle

176n
Changing a wheel Battery Driving with the space-saver
spare tireDrive cautiously and do not exceed a
speed of 50 mph (80 km/h).
Be aware that vehicle handling will be
altered. Slower brake response time,
longer braking distances and changed
steering characteristics may be
anticipated when approaching limit
conditions.
The changes in handling characteristics
will be even more pronounced in
conjunction with winter tires.
Only one space-saver spare tire
*
may be mounted at a time. Mount
a wheel and tire with the same size
and specifications as the others at the
earliest possible opportunity. Maintain
correct tire pressures. Refer to
page 28.<
LocationThe battery is located at the right-rear
of the luggage compartment. Remove
the luggage compartment floor panel
(refer to page 40), and give a screw-
driver or a coin a f-turn counter-clock-
wise to release and remove the two
fasteners, plus an additional fastener in
the top center side trim panel. In order
to remove the storage tray, slide the
side trim panel slightly upward.
Battery posts, terminals, and
related accessories contain lead
and lead compounds. Wash hands after
handling.<46cde045
Charge conditionYou can read the charge condition of
the battery with the "Magic Eye"
*
(a hydrometer):
>Green: adequate charge.
>Black: not adequately charged. The
battery must be recharged. Please
contact your BMW center for addi-
tional information.
>Yellow: replace the battery.
The service life specified for the
battery can be achieved only if it is
always kept adequately charged. If the
vehicle is primarily used for stop-and-
go traffic, be sure to check the charge
state more often.<

Tire Pressure Control* Self-diagnostics This system regularly checks tire pres-
sure and monitors all four tires even
while driving, so you do not have to.
Behind the valve stem in every wheel,
there is an extended-life electronic chip
that contains a pressure sensor, a
transmitter and a battery. The pressure
is measured in extremely short time
intervals and then transmitted by a
radio signal. If an irregularity is
detected, the transmission rate is
increased.
Located near each wheel and
embedded in the vehicle body is an
antenna that receives signals from the
wheel. A central electronics system
evaluates the quadruple signals and
forwards any changes.
The RDC provides an important contri-
bution to driving safety.46cde078
All
of the important electrical and elec-
tronic systems in the vehicle are tested
regularly and automatically Ð the driver
does not have to perform any extra
operations or adjustments.
The indicator lamps come on brießy
after the ignition has been turned on, for
example.
While you are driving, the functional
status of the actuator motors (for the
windshield wipers, power windows,
seats, etc.) is constantly being analyzed
by electrical measurements in the relays.
In the same manner, the electrical
resistance of the airbag ignition genera-
tors and all of the remaining airbag
components is measured at all times. Any
fault in this system would be detected
immediately by a current ßuctuation that 46cde052
would necessarily accompany it.
The fault
would be indicated immediately by the
airbag warning lamp.
Even after you shut off the engine, the
overall functional status of your vehicle is
monitored. For example, all of the ßaps of
the heating and ventilation system travel
to the nearest limit position. This action
ensures that the system will be able to
provide defrosting, regardless of other
circumstances, e. g. if a malfunction in the
air conditioner/automatic climate control
system
* should occur during the night
while the vehicle is parked.
A calibration cycle runs every tenth time
the engine is shut off. During this cycle,
the actuator motors of all the heating and
ventilation ßaps travel to their limit stops
in both directions. The limit positions and
the return travel paths are checked in this
manner in order to ensure that appro-
priate adjustments for the operating
elements can be made at any time.
You will hear the sounds of the air ßaps as
the air conditioner/automatic climate
control* carries out its self-diagnostic
functions after the ignition has been shut
off. All of the other self-diagnostics func-
tions operate silently in the background.
Any possible faults detected during these
self-diagnostics can be read out and
corrected by your BMW center
during the
next regularly scheduled maintenance.
