Brakes:
Do not drive with your foot resting
on the brake pedal. Even light but
consistent pedal pressure can lead to
high temperatures, brake wear, and
possibly to brake failure.
Aquaplaning:
When driving on wet or slushy roads,
reduce vehicle speed. If you do not, a
wedge of water may form between the
tires and the road surface. This
phenomenon is referred to as aqua-
planing or hydroplaning. It is character-
ized by a partial or complete loss of
contact between the tires and the road
surface. The ultimate results are loss of
steering and braking control.
Driving through water:
Do not drive through water on the road
if it is deeper than 1 ft (30 cm), and then
only at walking speed. Otherwise, the
vehicle's engine, the electrical systems
and the transmission may be damaged.
Clothes hooks (for the hardtop):
When suspending clothing from the
hooks, be sure that they will not
obstruct the driver's vision. Do not hang
heavy objects on the hooks. If you do
so, they could cause personal injury
during braking or evasive maneuvers.<
The catalytic converter reduces harmful
exhaust emissions.
It is designed for use with unleaded fuel
only. Even minute quantities of lead
would be enough to permanently
damage both the catalytic converter
and the system oxygen sensor.
To ensure efficient, trouble-free engine
operation and to avoid potential
damage:
>Be sure to comply with the scheduled
maintenance requirements.
>Fill the fuel tank well before it is
empty.
>Tow-start only when the engine is
cold. If you attempt to tow-start with
a warm engine, unburned residual
fuel in the catalytic converter could
ignite and cause damage. It is better
to jump-start the vehicle with outside
assistance.
>Avoid other situations in which the
fuel is not burned, or burns incom-
pletely, such as engaging the starter
frequently or for extended periods, or
repeated start attempts in which the
engine does not start (stopping and
restarting an engine which is running
properly does not present a problem).
Never allow the engine to run with
any of the spark plug cables discon-
nected.Be sure to comply with the
preceding instructions to prevent
unburned fuel from reaching the cata-
lytic converter. If you do not, the cata-
lytic converter could respond by
overheating, leading to serious
damage.
Very high temperatures occur in any
vehicle equipped with a catalytic
converter. Heat shields are installed
adjacent to some sections of the
exhaust system. Never remove these
shields; do not apply undercoating to
their surfaces. When driving, standing
at idle, and parking the vehicle, take
extra care to avoid contact between the
exhaust system and flammable mate-
rials (grass, hay, leaves, etc.). Such
contact could lead to a fire, resulting in
serious personal injury and property
damage.<

Caring for your vehicleWindow 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.
Clean the wiper blades with soapy
water. The wiper blades should be
replaced twice a year Ð before and after
the winter months. This is especially
important for vehicles with a rain
sensor.
Use only wiper blades approved
by BMW.<
Caring for other vehicle
components and materials Light-alloy wheels should be treated
with alloy wheel cleaner, especially
during the winter months. However, do
not use aggressive products contain-
ing acids, strong alkalis or abrasive
cleaning agents, nor steam cleaners
operating at temperatures above
140 7 (+60 6) (follow the manufac-
turer's instructions).
If your vehicle has chrome parts
*, such
as the window frames and door handles,
clean these parts carefully with ample
clean water and a shampoo supplement
if desired, especially if they have an
accumulation of road salt. Use a chrome
polish for an additional treatment.
Plastic components, vinyl upholstery,
headliners (hardtop), lamp lenses, the
clear cover of the instrument panel and
components with a sprayed dull black
surface can be cleaned with water (add
plastic shampoo as required). Do not
allow moisture to soak through the
seats or headliner (hardtop). Never use
solvents such as lacquer thinner,
heavy-duty grease remover, fuels, or
similar substances. Rubber components should be cleaned
with water only; a rubber treatment or
silicone spray may also be applied.
Do not remove safety belts to clean
them. Clean them with mild soapy
water only. Do not use chemicals or dry
cleaners to clean safety belts, since this
could damage the belt fabric.
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.
Use only a damp cloth to clean trim
panels made of real wood
* and other
parts constructed of real wood
*. Follow
up by drying with a soft cloth.
Use the cleaning and car-care
products available at your BMW
center.<

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.
