OBD interface socket The 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 vehicle's
lifetime. The system monitors emission-
related components and systems for
deterioration and malfunction.530us105
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 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.<

The operating life of these lamp units is
extremely long and the likelihood of
failure very low, provided that they are
not switched on and off a very great
number of times. If one of these bulbs
should nevertheless fail, it is possible to
continue driving with great caution
using the fog lamps, provided traffic
laws in your area do not prohibit this.
Because of the extremely high
voltages involved, any work on the
xenon lighting system should be carried
out by technically-qualified personnel
only. Failure to comply with this creates
a risk of fatal injury.< Turn signal indicators/Side lamps

Changing a wheel5 Position the jack at the jacking point
closest to the flat tire so that the
jack base is vertically below the
jacking point and the entire surface
of the head of the jack will move
into the square recess of the jacking
point (refer to the illustration detail)
when the jack is cranked.
6 Jack the vehicle up until the wheel
you are changing is raised from the
ground.
7 Unscrew the lug bolts and remove
the wheel.
8 Remove accumulations of mud or
dirt from the mounting surfaces of
the wheel and hub. Clean the lug
bolts.
9 Position the spare wheel. Secure
the wheel by turning at least two lug
bolts into opposite bolt holes.530us203
10 Screw in the remaining lug bolts.
Tighten all the bolts securely.
11 Lower the jack and remove it from
beneath the vehicle.
12 Tighten the lug bolts in a diagonal
pattern.
13 Check and correct the tire inflation
pressure at the earliest opportunity.
The vehicle jack is designed for
changing wheels only. Do not
attempt to raise another vehicle model
with it or to raise any load of any kind.
To do so could cause accidents and
personal injury.
To ensure continued safety, have the
tightness of the lug bolts checked with
a calibrated lug wrench [torque specifi-
cation: 101 ft-lb (140 Nm)] at the
earliest opportunity.<
Store the wheel and the tools in the
order opposite that for removal.
Before removing the support rod,
be sure that the tailgate is held
down firmly. If you fail to do so, it could
retract sharply upward and cause
personal injury and vehicle damage.
After you remove the rod, close the tail-
gate carefully. Continue to hold it firmly
until it is completely closed.<
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.
The spare wheel has a size
235/65 R 17 tire. If you have
mounted tires on your vehicle with a
different size, have wheels and tires of
the same size and specification rein-
stalled as soon as possible.
When the spare wheel is mounted, the
maximum speed rating is 130 mph
(210 km/h).<

Battery
Battery posts, terminals and
related accessories contain lead
and lead compounds. Wash hands after
handling.
Battery location The battery is located in the floor of the
vehicle below the spare wheel. 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. Since the battery is mainte-
nance-free, the following is for your
information only.<
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.
Before handling the battery,
please read the following infor-
mation.
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.
Do not allow children to have
access to batteries and battery
acid.
Never allow sparks or open
flame near the battery. Do not
smoke in the vicinity of the
battery. Avoid sparks from electrical
cables or electrical equipment. Turn the
key to position 0 in the steering lock
when you are disconnecting or
connecting the battery. Never short-
circuit the battery terminals. This
creates a risk of injury from high-energy
sparks.
A highly-explosive gas is
generated when the battery is
charged.
If you happen to get acid in your
eyes, rinse thoroughly for
15 minutes with clear water.
Following that, consult a physician
immediately. If you get acid spray on
your skin or clothing, rinse with plenty
of water. If electrolyte is accidentally
swallowed, consult a physician immedi-
ately.
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.

Towing the vehicle
The towed vehicle should always
be the lighter of the two vehicles.
If this is not the case, it is no longer
possible to control vehicle response.<
Tow-starting It is not possible to start the engine of a
vehicle equipped with an automatic
transmission by towing or pushing.
For instructions on jump starting: refer
to page 190.
Never attempt to use your vehicle to
push another car. If you do so, damage
to the energy-absorbing bumpers could
result.
Towing a vehicle with automatic
transmission1 Place the selector lever in position N.
2 Towing speed:
Max. 45 mph (70 km/h).
3 Towing distance:
Max. 95 miles (150 km).
4 Leave the ignition key at position 1 to
ensure that the brake lamps, turn
signals, horn and windshield wipers
remain operative, and to prevent the
steering lock from engaging.
5 Switch on the hazard warning
flashers (comply with country-
specific regulations).
Find some means of identifying the
vehicle in tow, for instance, place a sign
or warning triangle in the rear window.
Make sure that the ignition key
remains in position 1 even when
the electrical system has failed. This will
prevent the steering lock from
engaging. The steering and brakes are
without power assist when the engine is
not running. This means that increased
effort is required for steering and
braking.<
Towing with a commercial tow
truck>Do not tow with sling-type equip-
ment.
>Use a wheel lift or flat bed carrier.
>Please comply with applicable towing
laws.
Never allow passengers to ride in
a towed vehicle for any reason.< 530us138

Overview
199nDSP sound system* Rearview mirrors with automatic dimmer*
The DSP Professional premium sound
system features a special amplifier
combined with Digital Sound
Processing (DSP) and integrated
speakers to surround you with crisp,
true-to-life sound reproduction. The
speaker system's subwoofers, woofers,
midrange speakers and tweeters
furnish you with an impressively full-
bodied listening experience. The indi-
vidual components are oriented so as
to produce the aural sensation that you
would experience facing the stage in a
concert hall. The system also automati-
cally adjusts the bass and treble
settings to compensate for changes in
volume and vehicle speed.
530us142
The interior and exterior rearview
mirrors with automatic dimming feature
reduce glare from following traffic by
adapting the intensity of the reflected
images to correspond to levels of light
registered by the unit's sensors. The
mirrors revert to their undimmed setting
as soon as the light source disappears.
A forward facing sensor is mounted on
the front of the interior mirror housing
and is designed to monitor light levels
in the area forward of the vehicle.
A second sensor is integrated within
the mirror's glass. The electronic
control system operates by comparing
the respective levels of luminous inten-
sity in front of and behind the vehicle.
390de113
The difference provides the basic
parameter used to modulate an elec-
trical current and induce chemical
changes in a semisolid layer incorpo-
rated in the lenses.
The semisolid reacts chemically to this
electrical current, thus providing
dimming of the mirrors through an infi-
nitely-variable range (electrochromic
technology).
As a result, it is no longer necessary to
dim the interior mirror manually, and the
driver can concentrate completely on
traffic conditions.

200nRain sensor* Front axle
The rain sensor controls windshield
wiper operation, depending on how wet
the windshield is.
Infrared light is carried along the
surface of the windshield in an optical
conductor in such a manner that it is
reflected completely when the wind-
shield is dry. The quantity of reflected
light is measured.
If the window is covered with beads of
water, the amount of light that is
reflected is decreased since the
infrared light at the surface of the wind-
shield can then escape. The quantity of
reflected light is thus a means of
gauging the degree of wetness on the
windshield.
390de133
When the system is set to the "Intermit-
tent" wiper speed, the wipers react
immediately — if water is splashed onto
the windshield by vehicles traveling
ahead of you, for example. As a result,
the rain sensor provides a contribution
to driving safety and comfort.
The double-jointed suspension strut
axle is based on the same concept as
the one in the 7 Series, but was totally
re-developed because of the require-
ments for all-wheel drive. Parts
subjected to particularly high stress
levels for guiding the wheels are
designed as steel-forged parts to meet
the demands made by rougher roads.
The load-bearing front axle has large-
volume, hydraulically cushioned rubber
bearings that allow the axle to absorb
the reactive forces from the engine and
the braking forces from the front
wheels. An integrated rigid plate over
the load-bearing front axle provides
superb support against the lateral
forces introduced by the control arm
(wishbone), and also serves as an
effective protective barrier for the oil
pan and steering.
