Laws and regulations
California Proposition 65
warning
California laws require us to state the fol-
lowing warning:
Engine exhaust and a wide variety of
automobile components and parts,
including components found in the interior
furnishings in a vehicle, contain or emit
chemicals known to the State of California
to cause cancer and birth defects and
reproductive harm. In addition, certain flu-
ids contained in vehicles and certain prod-
ucts of component wear contain or emit
chemicals known to the State of CA to
cause cancer and birth defects or other
reproductive harm. Battery posts, terminals
and related accessories contain lead and
lead compounds. Wash your hands after
handling. Used engine oil contains chemi-
cals that have caused cancer in laboratory
animals. Always protect your skin by wash-
ing thoroughly with soap and water.<
OBD interface socket
The Onboard Diagnostic OBD interface
socket is located on the left of the driver's
side under the instrument 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 emission
control system for the vehicle's lifetime. The system monitors emission-related
components and system for deterioration
and malfunction.
If the Service Engine Soon indicator
lamp comes on either continuously
or intermittently, this indicates a
fault in the emissions-related electronic
systems. Although the vehicle remains
operational, you should have the systems
checked by your BMW center at the earli-
est possible opportunity.
The 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
next opportunity.
If the indicator blinks or flashes, this indi-
cates 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 compo-
nents, especially the catalytic converter.
Service Engine Soon warning lamp
for Canadian models.
If the gas cap is not on tight enough,
the OBD system can detect leaking
vapor and the indicator will light up. If the
gas cap is then tightened, the indicator will
usually go out after a short period of time.<

Replacement procedures
Onboard tool kit
The onboard tool kit is stored in a tool
pouch. It is located in the luggage compart-
ment beneath the floor panel.
Windshield wiper blades
1.Fold the wiper arm completely out from
the windshield
2.Position the wiper blade at an angle and
pull the release spring, see arrow
3.Fold the wiper blade down and unhook
it toward the windshield
4.Pull the wiper blade past the wiper arm
toward the top
5.Insert a new wiper blade and apply
pressure until you hear it engage.
Lamps and bulbs
The lamps and bulbs make essential contri-
butions to the safety of your vehicle. There-
fore, comply fully with the following instruc-
tions during bulb replacement. If you are
not familiar with the procedures, BMW rec-
ommends that you have your BMW center
carry out the work.
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 ser-
vice life of the bulb. Use a clean cloth,
paper napkin or a similar material, or hold
the bulb by its metallic base.<
A replacement bulb set is available from
your BMW center.
Before working on the electrical sys-
tem, switch off the electrical acces-
sory you are working on or disconnect the
cable from the negative terminal of the bat-
tery. Failure to observe this precaution
could result in short circuits.
To prevent injuries and damage, always
comply with any instructions provided by
the bulb manufacturer.<

2.Remove and replace the bulb
3.Install in the reverse order.
When cleaning the headlamps,
please observe the instructions in the

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 cau-
tion using the fog lamps, provided traffic
laws in your area do not prohibit this.
Because of the extremely high volt-
ages involved, any work on the xenon
lighting system, including bulb-changing,
should be carried out by technically quali-
fied personnel only. Otherwise, there is a
risk of fatal injury.<

Changing a wheel
Run Flat tires
Your BMW is equipped with Run Flat tires.
Therefore, the wheel no longer has to be
changed immediately in the event of a loss
in inflation pressure.
Run Flat tires are labeled on the sidewall
with a circular symbol containing the letters
RSC. Refer to page 80.
BMW recommends that you consult your
BMW center if you wish to replace the tires
of your BMW, or change from summer to
winter tires or vice versa.
Your BMW center knows how to work with
Run Flat tires and is equipped with the nec-
essary special tools.
When mounting or replacing summer
tires with winter tires, or vice versa,
use only Run Flat tires since no spare
wheel is available in the event of a flat.<
Jacking points
The jacking points are located at the posi-
tions indicated in the illustration.
Your BMW center can provide you
with a suitable jack.<
Battery
Maintenance
The battery is completely maintenance-
free. This means that the original electro-
lyte will normally last for the service life of
the battery under moderate climatic condi-
tions.
Please consult your BMW center
whenever you have any questions
concerning the battery.<
Indicator lamp
The indicator lamp for the battery
charge current lights up:
The battery is no longer being
charged. The alternator drive belt is defec-
tive or there is a malfunction in the charging
circuit of the alternator. Please contact the
nearest BMW center.
If the drive belt is defective, pull over
and switch off the engine immediately
to prevent overheating and serious engine
damage.
If the onboard supply voltage drops to a
very low level, increased steering effort
may also be necessary.<

Replacement procedures

Charging the battery
Charge the battery in the vehicle only when
the engine is not running. For information
on connections, refer to Jump-starting on
page 94.
Battery disposal
Return used batteries to a recycling
point or to your BMW center. Maintain
the battery in an upright position for trans-
port and storage. Secure the battery
against tilting when transporting.<

Do not attempt to repair a burned fuse
or replace it with a fuse having a dif-
ferent color or amperage rating. To do this
could cause a fire in the vehicle as a result
of circuit overload.<
