Technical modifications California Proposition 65 Warning Any BMW center will be glad to inform
you of the advisability, legal require-
ments and factory recommendations
regarding technical modifications on
your vehicle. For this purpose, the
BMW center will require the Vehicle
Identification Number and, in some
cases, also the engine number. 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. The concept
behind their operation is related to that
employed for lasers, and they are offi-
cially designated as Class 1 light-emit-
ting diodes.
Do not remove the protective lens
and avoid staring directly at the
unfiltered beam for extended periods
(several hours). To do so could result in
inflammation of the iris.<
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 socket The OBD interface socket for onboard
diagnostics is located on the driver's
side at the left-hand bottom of the
instrument panel and under a cover.
The cover has the letters "OBD" on it.
The purpose of the OBD system is to
assure proper emission control system
operation for the vehicle's lifetime by
monitoring emission-related compo-
nents and systems for deterioration and
malfunction.460us250
An illuminated indicator informs
you of the need for service, not
that you need to stop the
vehicle. Your system should be
checked, however, at the earliest
possible opportunity by your BMW
center.
If the indicator blinks or flashes, this
indicates a high level of engine misfire.
Reduce speed and contact your
nearest BMW center immediately.
Severe engine misfire over even a short
period of time can seriously damage
emission control components, espe-
cially 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 are essential
factors contributing to the safety of your
vehicle. For this reason, 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.<

The H7 bulb is pressurized. There-
fore, wear safety glasses and
protective gloves. Failure to comply
with this precaution could lead to injury
if the bulb is accidentally damaged
during replacement.<

turn left to release the bulb holder.
2 Remove and replace the bulb.460de130
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 contami-
nation (such as insects) by soaking with
BMW Car Shampoo and then rinsing
with plenty of water. Always use a
deicer spray to remove accumulated
ice and snow Ð never use a scraper.<
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 front fog lamps, provided
traffic laws in your area do not prohibit
this.
Because of the extremely high
voltages involved, any work on the
lighting system should be performed
only by technicians with the appropriate
qualifications. Failure to comply with
this creates a risk of fatal injury.<
