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 system is to
ensure proper operation of the emis-
sion control system for the vehicleÕs
lifetime. The system monitors emis-
sions-related components and systems
to detect deterioration and malfunction.390us739
An illuminated lamp 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 speed
and consult the nearest BMW center as
soon as possible. Severe engine misfire
over only a short period of time can
seriously damage emissions-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 are essential
factors contributing to the safety of your
vehicle. For this reason, you should
follow the instructions below carefully
when replacing a bulb. 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 into 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.
Whenever working on the elec-
trical system, switch off the elec-
trical accessory you are working on or
disconnect the cable from the negative
terminal of the battery. Failure to do this
could result in short circuits.
To prevent injuries and damage,
comply with any instructions provided
by the bulb manufacturer.<

can result in physical injury if the bulb

Battery Fuses
Battery posts, terminals and other
components contain lead and lead
compounds. Wash hands after
handling.<
Battery careThe battery is maintenance-free, that is,
the original electrolyte will normally last
for the service life of the battery under
moderate climatic conditions.
For all questions that regard the
battery, please consult your BMW
center. The battery is completely main-
tenance-free; the following section is
provided for your information only.<
Do not disconnect the battery
when the engine is running, as the
ensuing voltage surge would damage
the vehicle's onboard electronics.<
Charging the batteryWhen charging the battery in the
vehicle, leave the engine off at all times.
Connect the charge cables to the termi-
nals in the engine compartment (for
terminal locations, refer to "Jump-
starting" on page 162.

cling point or your BMW center.
Maintain the battery in an upright posi-
tion for transport and storage. Secure
the battery against tilting during trans-
port.<
