prevent the formation of condensa-
tion
6. Increase the tire inflation pressure to
51 psi (350 kPa).Before parking the vehicle for
storage1. Dry the parking brake and footbrake
by brake applications to prevent the
brake rotors and drums from
corroding
2. Park the vehicle in a covered, dry,
and well-ventilated room. Place the
transmission in 1st gear or set the
selector lever to the "P" position.

Any BMW center will be happy to
advise you concerning the advisability,
legal implications and factory recom-
mendations for technical modifications
to the vehicle. For this purpose, the
BMW center will require the Vehicle
Identification Number. The engine
number is also required in some
instances.
Light-emitting diodes (LEDs)Light-emitting diodes installed behind
translucent lenses serve as the light
source for many of the controls and
displays in your vehicle. These LEDs
are similar to conventional laser tech-
nology.
Do not remove the protective lens
and avoid staring directly at the
unfiltered beam for extended periods
(several hours), since inflammation of
the iris could result.<
California laws require us to state the
following warning:
Engine exhaust, some of its
constituents, and certain vehicle
components contain or emit chemicals
known to the State of California to
cause cancer and birth defects or other
reproductive harm.<

OBD interface socketAccess to the interface socket for the
Onboard Diagnostic system (OBD):
Lift off the side cover in the center
console on the passenger's side
(arrow).
The purpose of the OBD system is to
ensure proper operation of the emis-
sion control system throughout the
vehicle's lifetime by monitoring emis-
sion-related components and systems
for deterioration and malfunction.367us235
An illuminated indicator informs
you of the need for service,
but 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.
"Service Engine Soon" warning
lamp 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.<

Lamps and bulbsThe lamps and bulbs make essential
contributions to the safety of your
vehicle. Therefore, comply fully with the
following instructions during bulb
replacement. If you are not familiar with
any of the procedures, consult your
BMW center.
Do not touch the glass portion of
a new bulb with your bare hands
since even small amounts of impurities
burn in to the surface and reduce the
service life of the bulb. Use a clean
cloth, paper napkin, or a similar mate-
rial, or hold the bulb by its metallic
base.<
A replacement bulb set is available from
your BMW center.
Before working on the electrical
system, switch off the electrical
accessory you are working on or
disconnect the cable from the negative
terminal of the battery. Failure to
observe this precaution could result in
short circuits.
To prevent injuries and damage,
comply with any instructions provided
by the bulb manufacturer.<
The illustration depicts the right side
of the engine compartment.1 High beams HB3 bulb, 65 watts2 Low beams HB4 bulb, 55 watts
