OBD Socket
The Onboard Diagnostics 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 sys-
tem for the vehicle's lifetime. The system mon-
itors emission-related components and sys-
tems for deterioration and malfunction.
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.
Display of the previously described
malfunction on Canadian models.
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 mis-
fire over only a short period of time can seri-
ously damage emissions control components,
especially the catalytic converter.
When the fuel 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 subsequently tightened, the
indicator should go out within a few days.<
Event Data Recorders
Your vehicle may be equipped with one or more
sensing and diagnostic modules or a recording
device capable of recording or transmitting cer-
tain vehicle data or information. In addition, if
you have a Subscription Service Agreement for
the BMW Assist system, certain vehicle infor-
mation may be transmitted or recorded in order
to provide such services.
Care
Important information on the care and mainte-
nance of your BMW is contained in the Caring
for your vehicle brochure.

Lamps and bulbs
Lamps and bulbs make an essential contribu-
tion to vehicle safety. You must be duly diligent
in replacing them. BMW recommends having
your BMW center perform any work that you do
not feel competent to perform yourself or that is
not described here.Never touch the glass of new bulbs with
your bare fingers, as even minute
amounts of contamination will burn into the
bulb's surface and reduce its service life. Use a
clean cloth, napkin, etc., or hold the bulb by its
metal socket.<
You can obtain a selection of replacement bulbs
at your BMW center.
Whenever you perform any work on the
lighting system, turn off the lights
involved so as to prevent short circuits from
occurring. To avoid possible injury or equip-
ment damage when replacing bulbs, observe
any instructions provided by the bulb manufac-
turer.<
For care and maintenance of the headlamps,
please follow the instructions in the separate
Caring for your vehicle brochure.

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. In the unlikely event that one
of these lamps should fail, you can respond by
switching on your fog lamps and proceeding
carefully in accordance with the reduced visibil-
ity, where allowed by law.
Have work on the Xenon lighting system
performed only by your BMW center or a
workshop that works according to BMW repair
procedures with correspondingly trained per-
sonnel. Due to the high voltage present in the
system, there is a danger of fatal injuries when
work is carried out improperly.<
Parking and roadside parking lamps

LEDs light-emitting diodes
Light-emitting diodes installed behind translu-
cent lenses serve as the light source for many of
the controls and displays in your vehicle. These
light-emitting diodes, which operate using a
concept similar to that applied in conventional
lasers, are officially designated as Class 1 light-
emitting diodes.
Do not remove the covers, and never
stare directly into the unfiltered light for
several hours, as this could result in irritation of
the retina.<
Changing wheels
Safety precautions in the event of a flat
tire or wheel change: Park the vehicle as
far as possible from passing traffic and on solid
ground. Switch on the hazard warning flashers.
Lock the steering wheel in straight-ahead set-
ting of the wheels. Apply the handbrake and
engage first gear, reverse gear or selector lever
position P.
Have all vehicle occupants get out of the vehicle
and ensure that they remain outside the imme-
diate area in a safe place, such as behind a guardrail.
If a warning triangle or portable hazard warning
lamp is required, set it up on the roadside at an
appropriate distance from the rear of the vehi-
cle. Comply with all safety guidelines and regu-
lations.
Change the wheel only on a level, firm surface
which is not slippery. The vehicle or the jack
could slip to the side if you attempt to raise the
vehicle on a soft or slippery surface such as
snow, ice, tiles, etc.
Position the jack on a firm support surface.
Do not use a wooden block or similar object as a
support base for the jack, as this would prevent
it from extending to its full support height and
reduce its load-carrying capacity.
To avoid serious or fatal injury: never lie under
the vehicle, and never start the engine while it is
supported by the jack.<
What you will need
To avoid rattling noises later on, note the posi-
tions of the tools before removing them, then
return them to their initial positions after com-
pleting work.

the other side of the vehicle, or on inclines,
in front of this wheel. On a steep grade, take
other steps to prevent the vehicle from roll-
ing.
3.Loosen the lug bolts a half turn.
Jacking up vehicle
1.Position the vehicle jack at the jacking point
closest to the wheel so that the entire sur-
face of the jack base rests on the ground
perpendicularly beneath the jacking point.
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.<2.Guide the jack head into the rectangular
recess of the jacking point when cranking
up, refer to illustration detail.
3.Jack the vehicle up until the wheel you are
changing is raised from the ground.
Mounting a wheel
1.Unscrew the lug bolts and remove the
wheel.
2.Remove accumulations of mud or dirt from
the mounting surfaces of the wheel and
hub. Also clean the lug bolts.
3.Position the new wheel or compact wheel.
Secure the wheel by turning at least two lug
bolts into opposite bolt holes.
When you mount wheels other than Genu-
ine BMW light-alloy wheels, different lug
bolts may also be required.
4.Screw in the remaining lug bolts. Tighten all
the bolts securely in a diagonal pattern.
5.Lower the vehicle and remove the jack from
beneath the vehicle.
After mounting
1.Tighten the lug bolts in a diagonal pattern.
To ensure safety, always have the
lug bolts checked with a calibrated
torque wrench as soon as possible to
ensure that they are tightened to the speci-
fied torque. The tightening torque is
88.5 lb ft/120 Nm.<
2.When stowing the wheel and tools in the
vehicle, execute these steps in the reverse
order.

Emergency calling*
Conditions for an emergency call:
>Once ignition key is in position 1.
>The car phone is logged on to a cellular
telephone network.
>The emergency call system is operable.
Initiating an emergency call
1.To open the protective cover of the keypad:
touch the protective cover.
2.Press the button for at least 2 seconds.
The indicator lamp in the button lights up.
As soon as the voice connection to the
BMW Assist response center has been
established, the indicator lamp flashes.
If conditions allow, remain in the vehicle until
the connection has been established. You will
then be able to provide a detailed description of
the situation.
If the current location of your vehicle can be
determined with vehicles with an activated
BMW Assist, it will be transmitted to the BMW
Assist response center.
Activating BMW Assist, refer to page161.
If the indicator lamp flashes, but you are unable
to hear the BMW Assist response center
through the hands-free system, this could indi-
cate, for instance, that the hands-free system
is no longer operational. However, the BMW
Assist response center may then still be able to
hear you.Under certain conditions, an emergency call
is automatically initiated immediately after a
severe accident. The automatic emergency call
is not affected by the button being pressed.
For technical reasons, the emergency call
cannot be guaranteed under unfavorable
conditions. Always observe all legal regulations
requiring a warning triangle to be carried
in the vehicle.<
The warning triangle is located in the luggage
compartment lid.
Loosen the wingnut to open.
First-aid kit*
Some of the articles contained in the first-
aid kit have a limited service life. There-
fore, check the expiration dates of the contents
regularly and replace the contents concerned in
good time if necessary. You can find replace-
ments in any pharmacy. Comply with legal
requirements requiring you to carry a first-aid
kit in the vehicle.<

The towing vehicle may not be lighter
than the vehicle to be towed, as otherwise
it will not be possible to control vehicle
response.<
The tow fittings used should be on the same
side on both vehicles. Should it prove impossi-
ble to avoid mounting the tow bar at an offset
angle, please observe the following:
>Clearance and maneuvering capability will
be sharply limited during cornering.
>When mounted at an angle, the tow bar will
exert lateral forces, tending to push the
vehicle sideways.
Secure the tow bar to the tow fitting only.
Otherwise damage to other vehicle parts
could result.<
With tow rope
When starting off in the towing vehicle, make
sure that the tow rope is taut.To avoid jerking and the associated
stresses on vehicle components when
towing, always use nylon ropes or nylon straps.
Secure the tow rope to the tow fitting only.
Otherwise damage to other vehicle parts could
result.<
