Any BMW center will be happy to
advise you concerning the advisability,
legal implications and factory recom-
mendations for technical modifications
to the vehicle. For this purpose, the
BMW center will require the Vehicle
Identification Number. The engine
number is also required in some
instances.
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. These LEDs
are similar to conventional laser tech-
nology.
Do not remove the protective lens
and avoid staring directly at the
unfiltered beam for extended periods
(several hours), since inflammation of
the iris could result.<
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 socketAccess to the interface socket for the
Onboard Diagnostic system (OBD):
Lift off the side cover in the center
console on the passenger's side
(arrow).
The purpose of the OBD system is to
ensure proper operation of the emis-
sion control system throughout the
vehicle's lifetime by monitoring emis-
sion-related components and systems
for deterioration and malfunction.367us235
An illuminated indicator informs
you of the need for service,
but 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 emission 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.<

Wheel changePull the lifting handle up until the spare
wheel tray is lifted slightly. At the same
time, compress the locking spring
(arrow). This releases the spare wheel
(weight: approx. 8.8 lbs/4 kg). The
spare wheel must then be held with the
lifting handle.
Using the lifting handle, lower the spare
wheel bracket with storage tray and
spare wheel and place it on the ground.
Do not put your feet beneath the
rear of the vehicle because the
spare wheel could fall as it is being
lowered.< 367de270
Pull the storage tray with the spare
wheel completely out of the spare
wheel bracket toward the rear.367de276
Lift the spare wheel at the front. Lay it
down toward the rear next to the
storage tray and with the valve facing
upward. Quickly unscrew the valve
extension from the valve of the spare
wheel. Unscrew the valve cap from the
storage tray and mount it on the spare
wheel.
When the valve extension is
screwed onto or off of the spare
wheel, you may hear a brief hissing as
air escapes.<
The procedure for removing the spare
wheel is also illustrated with picto-
graphs located on the floor mat of the
luggage compartment.367de277

Wheel change13. Wheels with full wheel covers:
Place the wheel cover with the
valve opening over the valve. Use
both hands to press the cover
securely onto the rim
14. Check and correct the inflation
pressure at the earliest opportunity.
Use only the full wheel cover
installed by the factory. Other
wheel covers may not fit securely. The
full wheel cover may not be installed on
the spare wheel because the cover
could be damaged.<
The jack is designed for changing
wheels only. Do not attempt to lift
a different vehicle model or any other
type of load with the jack. To do so
could lead to property damage or
personal injury.
To ensure continued safety, check the
tightness of the lug bolts at the earliest
opportunity (torque specification:
72 lbs ft [100 Nm]).<
If light-alloy wheels other than Original
BMW light-alloy wheels have been
mounted, it may be necessary to use
different lug bolts for those wheels.
Replace the defective tire as soon as
possible and have the new wheel/tire
balanced.
Driving with the spare wheelDrive cautiously and do not exceed a
speed of 50 mph (80 km/h).
Be aware that vehicle handling will be
altered. Slower brake response time,
longer braking distances and changed
steering characteristics may be antici-
pated when approaching limit condi-
tions.
Only one spare wheel may be
mounted at any time. Mount a
wheel and tire with the same size and
specifications as the others at the
earliest possible opportunity. Maintain
the specified tire inflation pressures,
refer to the table on page 27.<

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
climatic conditions.SymbolsYou will find the following symbols on
your vehicle battery. To avoid injury,
please comply with the corresponding
precautions whenever you work with or
near the battery.
Please read the following infor-
mation before working with the
battery.
Wear eye protection. Do not
allow particles containing
battery acid or lead to come into
contact with your eyes, your skin, or
your clothing.
Battery acid is extremely corro-
sive. Wear eye protection and
protective gloves. Do not tip the
battery. Battery acid can leak from the
ventilation openings.
Ensure that children keep well
away from batteries and battery
acid.
Do not allow sparks or open
flame near the battery. Do not
smoke near the battery. Avoid
sparks from electrical cables or elec-
trical equipment. Turn the key to
position 0 in the ignition lock when the
battery is disconnected or connected.
Do not short circuit the battery termi-
nals. This creates a risk of personal
injury from high-voltage sparks.
A highly-explosive gas is gener-
ated when the battery is charged.
If acid is accidentally splashed
into your eyes, rinse them thor-
oughly for 15 minutes with clear
water. Following that, consult a physi-
cian immediately. If acid splashes onto
your skin or clothing, rinse immediately
with ample clean water. If acid is acci-
dentally swallowed, consult a physi-
cian immediately.
In order to protect the battery
case from ultraviolet radiation,
do not place it in direct sunlight.
A discharged battery can freeze. Store
the battery in areas where temperature
remains above freezing.
