Safety notes
A car phone can provide many services, in
an emergency even initiating a lifesaving
rescue. However, bear the following in
mind:
Adjustments
To avoid posing an unnecessary haz-
ard due to inattention, both to your
own vehicle's occupants and to other road
users: never attempt to use the controls or
make entries unless traffic and road condi-
tions allow.<
Using the phone in your vehicle
Using a portable phone to make and
receive calls while driving is now ille-
gal in virtually every country in the world.
Always use your hands-free system, or
stop your vehicle in an area where you will
not pose a safety hazard to other road
users and switch the engine off.<
Antenna
When using the phone, ensure that
all persons in the area are at least
20 in/50 cm from the antenna. Never use
your BMW portable phone if the antenna is
damaged. Contact between your skin and
a damaged antenna can result in minor
burns.
If the antenna is damaged, have it replaced
immediately.<
Special environmental conditions
Do not use your phone from within a
garage, or near an open hood. The air
in these areas could contain fuel vapors,
and the phone might generate sparks that
could result in burns.
This same precaution applies to opening
luggage compartment lids on vehicles
equipped for operation using natural gas or
hydrogen, and to all vehicles with luggage
compartment-mounted batteries.Always switch off your BMW portable
phone in areas where blasting work is
being conducted with explosives. The
phone signals could potentially act as a
high-frequency transmitter and set off
explosions.
Always switch off your BMW portable
phone in areas where an increased explo-
sion danger is present. This category
includes filling stations along with fuel and
chemical storage depots, etc., and all
areas in which the air can contain fuel,
chemicals or metal particles. Under these
conditions, your BMW portable phone
could conceivably generate sparks that
could lead to a fire or explosion. Always
observe all legal regulations governing the
use of portable phones in the vicinity of fill-
ing stations, chemical factories and other
areas where an explosion potential exists.
Never use the BMW portable phone in hos-
pitals, care centers or at other locations
where medical equipment may be in oper-
ation, such as accident sites, etc.
Your service provider can furnish you with
more detailed information on legal regula-
tions governing the use of your phone.<
Medical equipment
Portable phones can generate inter-
ference capable of preventing hearing
aids and cardiac pacemakers from operat-
ing correctly. If you or any occupant of the
vehicle will be using such equipment, con-
sult a physician or the manufacturer of the
equipment to determine whether it is ade-
quately shielded against high-frequency
energy.
Persons with cardiac pacemakers should
bear the following in mind:
Always hold the switched-on BMW porta-
ble phone more than 15 cm away from the
cardiac pacemaker.
Do not carry the BMW portable phone in
your breast pocket.
Use the ear on the opposite side of the car-
diac pacemaker to reduce the likelihood of

Refueling
Fuel filler door
Always switch off the engine before
refueling. If you do not, fuel cannot be
filled into the tank and a message will
appear in the Check Control.<
To open and close: briefly press the rear
edge of the fuel filler door.
Manual release
In the event of an electrical defect in the
system, you can release the fuel filler door
manually:
1.Lift the handle to remove the cover
panel on the right side of the luggage
compartment
2.Take the button with the fuel pump
symbol from the bracket and pull it to
unlock the fuel filler door.
Always observe all applicable precau-
tions and regulations when handling
fuels. Never carry spare fuel containers in
your vehicle. Whether empty or full, these
containers can leak, cause an explosion,
and lead to fire in the event of a collision.<
Simple and environmentally friendly
When handling fuels always observe
any safety guidelines posted at the
filling station.<
Put the filler cap in the bracket attached to
the fuel filler door.
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Lifting the filler
nozzle during refueling
>results in premature pump shutoff
>can lead to reduced efficiency in the
fuel-vapor recovery system.
The fuel tank is full when the filler nozzle
clicks off the first time.
Close the filler cap carefully after refu-
eling, continuing until you hear the
detent engage. While closing, be sure not
to squeeze the strap which is fastened to
the cap. A loose or missing cap will activate
a message in the Check Control.<
Fuel tank capacity: approx. 23.2 gallons/
88 liters, including the reserve capacity of
approx. 2.6 gallons/10 liters.
Never attempt to continue driving
until the tank is completely empty, as
engine functions could be affected, and the
vehicle could sustain damage as a result.<

Storage
Always store wheels and tires in a cool, dry
place with as little exposure to light as pos-
sible. Always protect tires against all con-
tact with oil, grease and fuels.
Do not exceed the maximum tire inflation
pressure indicated on the side wall of the
tire.
Run-flat tires*
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the
side of the tire. They consist of self-con-
tained tires and special rims. The tire rein-
forcement ensures that the tire retains
some residual safety in the event of pres-
sure drop and driving remains possible to
a restricted degree.
If you switch from summer to winter
tires, or vice versa, use run-flat tires,
as in the event of a breakdown there is no
spare wheel available. In this case, BMW
recommends that you consult your BMW
center. Your BMW center is qualified to
handle run-flat tires and 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.
In the case of complete inflation pressure
loss, 0 psi/kPa, or obvious tire damage,
you can estimate the possible distance for continued driving on the basis of the fol-
lowing guide values:
>With low load:
1 to 2 persons without luggage:
Approx. 150 miles/250 km
>With medium load:
2 persons, luggage compartment full, or
4 persons without luggage:
Approx. 90 miles/150 km
>With full load:
More than 4 persons, luggage compart-
ment full:
Approx. 30 miles/50 km.
Drive reservedly and do not exceed
a speed of 50 mph/80 km/h. With
inflation pressure loss, the driving charac-
teristics change, for example reduced track
stability on braking, extended braking dis-
tance, and altered self-steering character-
istics.<
Snow chains*
BMW only tests certain snow chains, clas-
sifies them as road-safe and approves
them. Consult your BMW center for more
information. BMW recommends only using
these approved, narrow-link snow chains.
These snow chains are approved exclu-
sively for use in pairs on the rear wheels,
and should only be mounted on tires
with the dimensions 245/50 R 18. Observe
the manufacturer's instructions when
installing snow chains.Do not exceed a
vehicle speed of 30 mph/50 km/h with the
chains mounted.
After mounting snow chains, do not
activate the Flat Tire Monitor.
When you are driving with snow chains, it
can be beneficial to switch off DSC briefly,
refer to page 93.<

stick out and wipe it off with a clean lint-
free cloth, paper towel, or similar mate-
rial
4.Carefully push the dipstick all the way
into the guide tube and pull it out again
5.The oil should extend to between the
two marks on the dipstick.
As is the case with fuel economy, the rate
at which the engine uses oil is strongly
influenced by driving style and operating
conditions.

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 thor-
oughly 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 emission-related
components and systems for deterioration
and malfunction.
An indicator lamp informs you of the
need for service, not of the need to
stop the vehicle. However, the sys-
tems should be checked by your BMW
center at the earliest possible opportunity.
Indicator lamp for Canadian mod-
els.
Under certain conditions, the indicator
lamp 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
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 lamp should go out
within a few days.<
