OBD interface socketThe Onboard Diagnostic (OBD) inter-
face socket is located on the left of the
driver's side at the bottom of the instru-
ment panel and under a cover. The
cover has the letters "OBD" on it.
The purpose of the OBD (Onboard-
Diagnostics) system is to assure proper
emission-control system operation for
the vehicle's lifetime by monitoring
emissions-related components and
systems to detect deterioration and
malfunction.390us739
An illuminated indicator informs
you of the need for service, 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 the
speed and consult the nearest BMW
center as soon as possible. Severe
engine misfire over only a short period
of time can seriously damage emis-
sions-control components, especially
the catalytic converter.
Service Engine Soon warning
lamp for Canadian models.
When the fuel 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 subsequently tightened, the indi-
cator should go out within a few days.<

The lamps and bulbs are essential fac-
tors contributing 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.
Always switch off all electrical
accessories and systems before
working on them. As an alternative, you
can also disconnect the cable from the
battery's negative terminal. Failure to
observe this precaution can lead to
short circuits.
To prevent injuries and damage,
comply with any instructions provided
by the bulb manufacturer.<

Lamps and bulbs 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 con-
tinue driving with great caution using
the fog lamps, provided traffic laws in
your area do not prohibit this.
Never attempt to perform bulb
changes or any other service oper-
ations on the xenon lamps. Always have
them serviced by professional techni-
cians. The extremely high voltages at
which these lamps operate constitute a
potentially lethal safety hazard.<
When cleaning the headlamps,
please observe the following:
>Do not clean by wiping with a dry
cloth (this causes 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
ample water
>Always use a deicer spray to remove
accumulated ice and snow Ð never
use a scraper.<

Repairing a flat tire Battery
If the inflation pressure does not
hold, complete step 10 and then
repeat steps 7 through 10.
The use of the M Mobility system may
be ineffective if the damaged area in
the tire is larger than approx. 0.15 in
(4 mm). If it should prove impossible to
restore the tire to operational status
using the M Mobility system, please
contact the nearest BMW center or
BMW Roadside Assistance at
1-800-332-4269.<
10. Unscrew the hose from the valve
and stow the M Mobility system in
the luggage compartment. Screw
the cap back onto the valve stem.
When you start driving again, do not
exceed the permissible maximum
speed of 50 mph (80 km/h).
You will find corresponding instructions
for using the M Mobility system on the
device.
Replace the defective tire as soon as
possible and have the wheel and tire
balanced. Reactivate the Flat Tire Mon-
itor, for additional information refer to
page 82. Have the M Mobility system
recharged. Contact your BMW center
for this.
Protect valve stems and valves from dirt
using screw-on valve stem caps. Dirty
valve stems frequently lead to slow
pressure loss.Battery posts, terminals and
related accessories contain lead
and lead compounds. Wash hands after
handling.<
Battery careThe battery is completely maintenance-
free. That means that the original elec-
trolyte will normally last for the service
life of the battery under moderate cli-
matic conditions.
Please consult the staff at your
BMW center whenever you have
any questions concerning the battery.
The battery is completely maintenance-
free; the following section is provided
for your information only.<
Never disconnect the battery
when the engine is running; the
ensuing voltage surge would seriously
damage the vehicle's onboard elec-
tronic systems.<
