sive materials to these components or
cover or modify them in any way. Do

either of which could result in personal
injury.< If you intend to store the vehicle

Preparation for storageHave the following operations
performed by your BMW center:

tration and top up if necessary

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.<
