Rules and regulations
California Proposition 65
Warning
California laws require us to issue 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 California
to cause cancer and birth defects or other
reproductive harm.
Battery posts, terminals and related acces-
sories contain lead and lead compounds.
Wash your hands after handling.
Used engine oil contains chemicals that
have caused cancer in laboratory animals.
Always protect your skin by washing
thoroughly with soap and water.<
OBD connector
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 emissions-related
components and systems for deterioration
and malfunction.
An illuminated indicator 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.
Indicator lamp for Canadian mod-
els.
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 emis-
sions 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
lamp will light up. If the filler cap is subse-
quently tightened, the indicator lamp
should go out within a few days.<

Replacing components
Onboard tool kit
The onboard tool kit is located in the lug-
gage compartment lid.
Loosen the wingnut to open.
Windshield wiper blades
To replace, fold the wiper arm up and hold.
Press the catches together while pushing
the wiper blade out of the front.
Lamps and bulbs
The lamps and bulbs are essential factors
contributing to the safety of your vehicle.
Therefore, comply fully with the following
instructions during bulb replacement. If you
are not familiar with the specified proce-
dures, have the replacements carried out at
your BMW center.
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.
In the case of bulbs where the replacement
is not described, please consult your BMW
center.<
You can obtain a selection of replacement
bulbs at your BMW center.
To prevent short circuits, before
working on any electrical system,
equipment or accessory you should always
switch it off and disconnect the cable from
the battery's negative terminal before start-
ing.
To avoid possible injury or equipment dam-
age when changing bulbs, observe any
instructions provided by the bulb manufac-
turer.<
When maintaining the headlamps,
please comply with the instructions in
the separate Caring for your vehicle bro-
chure.<

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 proceed-
ing carefully, where allowed by law.
To avoid the risk of potentially fatal
injuries: owing to the extremely high
voltages at which these units operate, ser-
vice work on the xenon lighting system
should always be entrusted to qualified
personnel.<

Changing a wheel
Safety measures in the event of a
breakdown or wheel change:
Park the vehicle as far away as possible
from moving traffic and on firm ground.
Switch on the hazard warning flashers.
Lock the steering wheel in straight-ahead
setting of the wheels. Apply the handbrake
and engage first gear, reverse gear or
selector lever to position P.
Have all vehicle occupants get out of the
vehicle and ensure that they remain outside
the immediate 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 vehicle.
Comply with all safety guidelines and regu-
lations.
Change the wheel only on a level, firm sur-
face 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-car-
rying 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
positions of the tools before removing
them, then return them to their initial posi-
tions after completing work.1Chock
2Vehicle jack
3Lug wrench
are located in the tool space in the rim of
the compact wheel. Raise the floor mat and
the cover beneath it. Take out the required
tool(s). After using the tools, return them to
the storage space.
Compact wheel*
1.Unscrew the wing nut 1
2.Remove the disk 2 to the side
3.Take out the tool brackets 3
4.Remove the compact wheel.
Procedure
1.Read carefully and comply with the
safety precautions on left-hand column
2.To secure the vehicle against move-
ment:
Place the wheel chock behind the front
wheel on the side opposite the side
being raised. If the vehicle is parked on
a downward slope, place the chock in
front of the wheel. If the wheel must be
changed on a surface with a more
severe slope, take additional precau-
tions to secure the vehicle from rolling

Replacing components
188 3.Loosen the lug bolts 1/2 a turn
4.Set up the jack beneath the jacking
point closest to the flat tire. Ensure that
the entire surface of the jack's base is in
firm contact with the ground and that
the jack itself is standing completely
vertical, not tilted, and that the fitting on
the top of the jack will align with the
rectangular recess on the vehicle when
you raise it, refer to illustration
5.Jack the vehicle up until the wheel you
are changing is raised from the ground
6.Unscrew the lug bolts and remove the
wheel
7.Remove accumulations of mud or dirt
from the mounting surfaces of the
wheel and hub. Clean the lug bolts
8.Position the new wheel or compact
wheel. Secure the wheel by turning at
least two lug bolts into opposite bolt
holes
9.Screw in the remaining lug bolts.
Tighten all the bolts securely in a diag-
onal pattern
10.Lower the jack and remove it from
beneath the vehicle
11.Tighten the lug bolts in a diagonal pat-
tern
12.Check and correct the tire inflation
pressure at the earliest opportunity.
Protect valve stems and valve stem
seal caps against dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<
After mounting the wheel or correcting the
inflation pressure, reinitialize the Flat Tire
Monitor, refer to page 81.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 safety, always have the lug bolts
checked with a calibrated torque wrench
as soon as possible to ensure that they are
tightened to the specified torque.
The tightening torque is 120 Nm.<
Reverse the removal sequence to store the
wheel and tools in the vehicle.
When you mount wheels other than Genu-
ine BMW light-alloy wheels, different lug
bolts may also be required.
Always have damaged tires replaced and
the wheel and tire assembly rebalanced at
the earliest possible opportunity.
Driving with the compact wheel
Drive reservedly and do not exceed a
speed of 50 mph/80 km/h.
The driving characteristics change, for
example reduced track stability on braking,
extended braking distance, and altered
self-steering characteristics in the limit
range. In conjunction with winter tires,
these characteristics are more pro-
nounced.
Only one compact wheel may be
mounted. You should fit wheels and
tires of the original size as quickly as possi-
ble.<
Battery
Battery care
The battery is 100% maintenance-free, i.e.,
the electrolyte will last for the life of the bat-
tery when the vehicle is operated in a tem-
perate climate.
For all questions that regard the bat-
tery, please consult your BMW cen-
ter.<

Charging the battery
Only charge the battery in the vehicle via
the terminals in the engine compartment
with the engine off. Connections, refer to
Jump-starting on page 192.
Disposal
Return used batteries to a recycling
point or your BMW center. Maintain
the battery in an upright position for trans-
port and storage. Always restrain the bat-
tery to prevent it from tipping over during
transport.<
Fuses
Never attempt to repair a blown fuse,
and do not replace a defective fuse
with a substitute of another color or amper-
age rating, as this could lead to a circuit
overload, ultimately resulting in a fire in the
vehicle.<
Spare fuses, plastic tweezers and details of
the fuse assignment are located in the
compartment for the onboard tool kit, refer
to page 184.
In the glove compartment
Turn the two snap fasteners outwards. Fold
the cover forwards or remove.
In the luggage compartment
Raise the floor mat and the cover beneath
it. Undo the screw connection of the right
side panel and pull out the panel.

Starting an emergency call*
Conditions for an emergency call:
>The car phone is logged on to a porta-
ble phone network
>The emergency call system is operable.
To start an emergency call:
1.To open the cover flap:
Briefly press the cover flap
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 general emergency number has
been set up, 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.
In vehicles where BMW Assist is enabled,
the phone system will automatically estab-
lish contact with the BMW Assist emer-
gency call center. If the current position of
your vehicle can be determined, this is
transferred to the BMW Assist emergency
call center.Activating BMW Assist, refer to page 161.
If the navigation system fails, the cur-
rent position of the vehicle is not
transmitted.<
If the indicator lamp flashes, but you are
unable to hear the emergency call center
through the hands-free system, this could
indicate, for instance, that the hands-free
system is no longer operational. However,
the emergency call center can still hear
you.
For technical reasons, the emergency
call cannot be guaranteed under
unfavorable conditions.<
Under certain conditions, an emergency
call is started automatically immediately
after a severe accident. The automatic
emergency call is not affected by the but-
ton being pressed.
