Rules and regulations
California Proposition 65
Warning
California laws require us to state the fol-
lowing warning:
Engine exhaust, some of its constitu-
ents, and certain vehicle components
contain or emit chemicals known to the
State of California to cause cancer and
birth defects and reproductive harm. In
addition, certain fluids contained in
vehicles and certain products of compo-
nent 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 tho-
roughly with soap and water.<
OBD connector
The Onboard Diagnostic Ð OBD Ð 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 systems 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.
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 will
light up. If the filler cap is subsequently
tightened, the indicator 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.
The adapter for the spare key can be stored
beneath the open-ended spanners.
Windshield wiper blades
To replace the blades, start by folding the
wipers out and away from the windshield,
refer to page 73.
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 on 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. To prevent short circuits, before wor-
king on any electrical system, equip-
ment or accessory you should always
switch it off and disconnect the cable from
the battery's negative terminal before star-
ting.
To avoid possible injury or equipment
damage when changing bulbs, observe any
instructions provided by the bulb manufac-
turer.<
When maintaining the headlamps,
please comply with the instructions in
the separate Care manual.<
Headlamps
For checking and adjusting headlamp
aim, please contact your BMW
center.<
Engine compartment, left side:
Turn the quick-release fasteners 905 coun-
terclockwise and remove the cover.
After replacing the bulb return the cover to
its original position and press the quick-
release fasteners down.

Run-flat tires*
You will recognize run-flat tires by a cir-
cular symbol containing the letters RSC on
the side of the tire. They consist of self-
contained tires and special rims. The tire
reinforcement ensures that the tire retains
some residual safety in the event of pres-
sure drop and driving remains possible to
a restricted degree. The vehicle is
equipped with a Flat Tire Monitor or TPM
Tire Pressure Monitor which indicates
punctures.
The reinforcement on the flanks of the
tires means that it is usually not pos-
sible to detect an air loss from outside.<
Flat tire
If you have a flat tire, the indicator lamp
symbol in the Check Control will light up in
red, and a message will appear. In addition,
a gong sounds.
Detailed information on the Flat Tire Mon-
itor or TPM Tire Pressure Monitor can be
found on page 98 or 99.
Reduce vehicle speed carefully to under
50 mph (80 km/h), avoiding hard brake
applications and steering maneuvers.
If the defective wheel is not recognizable
as such immediately, check the inflation
pressure in all four tires.
For reasons of safety, do not arrange
for run-flat tires to be repaired. Your
BMW center has the information needed
for working with these tires and is equipped
with the necessary special tools.<
Continuing driving with a damaged
tire
Driving on run-flat tires can continue
depending on the vehicle load and the
severity of the tire damage, at a maximum
speed of 50 mph (80 km/h). You can deter-
mine the possible mileage for continued
driving on the basis of the following general
indications:
>Tire inflation pressure 0 psi/kPa:
With empty vehicle approx. 90 miles
(150 km)
With full payload approx. 30 miles
(50 km)
>Tire inflation pressure 7 psi/50 kPa Ð
15 psi/100 kPa:
Approx. 300 miles (500 km)
>Tire inflation pressure greater than
15 psi/100 kPa:
approx. 600 miles (1000 km).
Drive reservedly and do not exceed a
speed of 50 mph (80 km/h). In the
case of air loss, you can expect changes in
vehicle handling such as reduce lane sta-
bility, longer braking distances, and
changes in self-steering properties.<
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
center. Since the battery is maintenance-
free, the following is for your information
only.<
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 203.

To avoid short circuits, as well as pos-
sible fires and personal injury, always
disconnect the cable from the battery's
negative terminal before working on the
vehicle's electrical system.<
Battery switch
Before storing the vehicle for an extended
period of several weeks or more, slide the
battery switch located behind the trim
panel on the right side of the luggage com-
partment to OFF. This reduces the current
flow from the battery for the period during
which the vehicle remains parked.
A message appears in the Check Control
panel. Please take note of the supplemen-
tary information provided in the Control
Display.
Never disconnect either battery cable
from its terminal while the engine is
running Ð the resulting voltage surge would
destroy the vehicle's electronic systems.<
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
Spare fuses are located on the fuse strip in
the glove compartment; plastic tweezers
can be found at the fuse holder in the lug-
gage compartment.
In the glove compartment
Press the tab on the cover to the front, then
fold up the cover.
Never attempt to repair a blown fuse,
and do not replace a defective fuse
with a substitute of another color or
amperage rating, as this could lead to a cir-
cuit overload, ultimately resulting in a fire in
the vehicle.<
In the luggage compartment
Use the handle to pull down the trim on the
right wall.

Giving and receiving assistance

Giving and receiving assistance
Warning triangle*
The warning triangle is conveniently stored
in the onboard tool kit mounted on the
inside of the luggage compartment lid.
Comply with legal requirements
requiring you to carry a hazard war-
ning triangle in the vehicle.<
First-aid kit*
You will also find the first-aid kit in the
onboard tool kit's container.
Some of the articles contained in the
first-aid kit have a limited service life.
For this reason, check the expiration dates
of each of the items regularly, and replace
any whose expiration dates have passed.
You can find replacements in any phar-
macy.
Always comply with laws requiring a first-
aid kit to be carried in the vehicle.<
Jump-starting
When your battery is discharged you can
use two jumper cables to start your vehicle
with power from the battery in a second
vehicle. You can also use the same method
to help start another vehicle. Use only
jumper cables with fully-insulated clamp
handles.
To avoid the risk of potentially fatal
injury, always avoid all contact with electrical components while the engine is
running. Carefully adhere to the following
sequence, both to prevent damage to one
or both vehicles, and to guard against pos-
sible personal injury.<
Preparing
1.Check whether the battery of the sup-
port vehicle has 12 Volts and approxi-
mately the same capacity (Ah). This
information can be found on the battery
2.Switch off the engine of the support
vehicle
3.Switch off any electrical systems and
components in both vehicles.
Ensure that no contact exists bet-
ween the bodywork on the two
vehicles Ð danger of short circuits.<
Connect the jumper cables
To avoid personal injury from sparks,
always observe this sequence when
connecting jumper cables.<
Your BMW is equipped with an auxiliary
terminal specifically designed for jump-
starting. It is located within the engine
compartment, see arrow 1 in the illustra-
tion. The symbol + is embossed on the
cover.
1.Remove the cover of the BMW auxiliary
terminal for jump starting
2.Use the jumper cable (+) to set up a
connection between the positive ter-
minal of the discharged battery and the
