OBD interface socketThe interface socket for onboard diag-
nostics is located on the left-hand side
of the driver's side, behind a specially
marked cover located beneath the
instrument panel. The cover has the
letters OBD on it.
This interface makes it possible to
access data on emissions-related
components using special equipment.
An illuminated indicator informs
you of the need for service, not
that you need to stop the
vehicle. However, the systems should
be checked by your BMW center at the
earliest possible opportunity.
If the indicator blinks or flashes, this
indicates a high level of engine misfire.
Reduce speed and contact the nearest
BMW center immediately. Severe
engine misfiring over even a short
period of time can seriously damage
emission control system components,
especially the catalytic converter.
SERVICE ENGINE SOON
warning lamp for Canadian
models.
If the fuel filler cap is not on tight
enough, the OBD system can
detect leaking vapor and the indicator
will light up. If the fuel filler cap is then
tightened, the indicator will usually go
out after a short period of time.<

The 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.<

Xenon lamps

The service life of these bulbs is very
long and the probability of a failure is
very low, provided that they are not
switched on and off an unusual number
of times. If one of these bulbs should
nevertheless fail, it is possible to
continue driving with great caution
using the fog lamps, provided local
traffic laws do not prohibit this.
Because of the extremely high
voltages involved, any work on the
lighting system should be carried out by
technically-qualified personnel only.
Otherwise, there is a risk of fatal
injury.<
