For your own safety
Use unleaded gasoline only. Fuels
containing up to 10% ethanol or
other oxygenates with up to 2.8% oxy-
gen by weight (i.e., 15% MTBE or
3% methanol plus an equivalent
amount of co-solvent) will not void the
applicable warranties with respect to
defects in materials or workmanship.
Field experience has indicated signifi-
cant differences in fuel quality (i.e., vol-
atility, composition, additives, etc.)
among gasolines offered for sale in the
United States and Canada. The use of
poor-quality fuels may result in drive-
ability, starting and stalling problems,
especially under certain environmental
conditions, such as high ambient tem-
perature and high altitude.
Should you encounter driveability prob-
lems that you suspect could be related
to the fuel you are using, we recom-
mend that you respond by switching to
a recognized high-quality brand.
Failure to comply with these recom-
mendations may result in unscheduled
maintenance.
Follow the relevant safety rules when
you are handling gasoline.

Important safety information!
For your own safety, use genuine
parts and accessories approved by
BMW.
When you purchase accessories tested
and approved by BMW and Original
BMW Parts, you simultaneously acquire
the assurance that they have been thor-
oughly tested by BMW to ensure opti-
mum performance when installed on
your vehicle.
BMW warrants these parts to be free

dust shields, telephones (including op-
eration of any portable cellular phone
from within the vehicle without using an
externally-mounted antenna) or trans-
ceiver equipment (C.B., walkie-talkie,
ham radio, for instance) may cause ex-
tensive damage to the vehicle, compro-
mise its safety, interfere with the vehi-
cle's electrical system, or affect the
validity of the BMW Limited Warranty.

REPORTING SAFETY DEFECTS

If you believe that your vehicle has a defect which could cause a crash or could cause injury or death, you should
immediately inform the National Highway Traffic Safety Administration (NHTSA) in addition to notifying BMW of
North America, Inc., P.O. Box 1227, Westwood, New Jersey 07675-1227, Telephone (201) 307-4000.
If NHTSA receives similar complaints, it may open an investigation, and if it finds that a safety defect exists in
a group of vehicles, it may order a recall and remedy campaign. However, NHTSA cannot become involved in
individual problems between you, your dealer, or BMW of North America, Inc.
To contact NHTSA, you may either call the Auto Safety Hotline toll-free at 1-800-424-9393 (or 366-0123 in

Refueling Fuel specifications
Before filling the tank, shut off the
engine. If you do not, fuel cannot
flow into the tank and the "Check En-
gine" warning lamp may come on.<
To open the fuel filler door, press
against its forward edge.
To unlock the fuel filler door if there is a
malfunction of the central locking sys-
tem, refer to page 178.
When handling fuels, comply with
all of the applicable safety precau-
tions and regulations pertaining to fuels.
Never carry spare fuel containers in
your vehicle. Whether empty or full,
these containers can leak, cause an ex-
plosion, or lead to fire in the event of a
collision.<
384de011
Open the filler cap carefully to
prevent fuel from spraying out.
Fuel spray may cause injury.
Do not top off. Topping off may cause
fuel spillage.<
Keep the filler cap in the bracket at-
tached to the fuel filler door.
When refueling, insert the filler nozzle
completely into the filler pipe. Pulling
the nozzle out of the pipe during refuel-
ing
>results in premature pump shutoff
>and will reduce the effect of the
recovery vapor system on the pump.
Close the fuel cap carefully after
refueling. A loose or missing cap
will activate the "Check Engine“ lamp.<
380de633
Use unleaded gasoline only.
Minimum octane requirement: 91 AKI.
BMW engines are equipped with knock
sensors and will adapt automatically
to different octane ratings, provided
that the minimum octane requirement
(87 AKI) is met.
Fuels with higher octane ratings will
provide enhanced performance and
lower fuel consumption, while the use
of fuels with lower octane ratings will
have the opposite effect.
Do not use leaded fuels. The use
of leaded fuels will cause perma-
nent damage to the system's oxygen
sensor and the catalytic convertor.<
AKI = Anti Knock Index

Tire inflation pressureThe inflation pressures are indicated on
a sticker attached to the B-pillar behind
the driver's door (visible with door
open). Check tire pressuresAll pressure specifications are indicated
in psi (kilopascal) with cold tires (cold =
ambient temperature).
For vehicles with Tire Pressure Control
(RDC)
*:
After a correction of the tire inflation
pressure, reactivate the system. Refer
to page 94.
460de163
Check tire inflation pressures reg-
ularly - at least every two weeks
and before beginning a longer trip. In-
correct tire pressure can otherwise lead
to tire damage and accidents.
Also check the inflation pressure of the
spare tire. Inflate the spare tire to the
highest inflation of any tire on your vehi-
cle.<
Comply with tire approval
specificationsThe inflation pressures in the table ap-
ply to tires from BMW-approved manu-
facturers. Your BMW center is familiar
with these pressures. Higher pressures
may be specified for tires from other
manufacturers. You will find a list of ap-
proved tires beginning on page 136.
Your vehicle is equipped with tires that
not only meet US standards, but also
European standards. We recommend
the exclusive use of BMW-approved
tires.

Electronic vehicle immobilizerThe key to securityYour BMW is equipped with a passive
anti–theft system. This electronic immo-
bilization system is designed to reduce
the susceptibility of your vehicle to theft
by making it impossible to start the en-
gine using any means other than the
special keys furnished with the vehicle.
Your BMW center can cancel the elec-
tronic system authorization for individ-
ual keys (for instance, in the event of
loss). A deactivated key can no longer
be used to start the engine.390de015
How the electronics workAt the heart of this system is an elec-
tronic chip which is integrated into the
key. The lock mechanism itself is actu-
ally a dual-function device, simulta-
neously serving as a communications
interface designed to allow the security
system to maintain a continuous stream
of variable, vehicle-specific signals with
the electronic circuitry in the key. The
system will not release the ignition, fuel
injection and starter unless it recog-
nizes an "authorized" key.
Force applied to the key can dam-
age the integrated electronic cir-
cuitry. A damaged key can no longer be
used to start the engine.<

Central locking system Door locks – outsideThe conceptThe central locking system is ready for
operation as soon as you close the
driver's door. The system engages and
releases the locks on the
>doors
>luggage compartment lid
>fuel filler door.
The central locking system can be
operated
>from outside via the driver's door or
luggage compartment lock and with
the remote control
>from inside via the central locking
button.
The fuel filler door remains unlocked
when you activate the system from in-
side the vehicle.
The anti-theft system is automatically
armed whenever you activate the cen-
tral locking system from outside the ve-
hicle. The alarm system is also acti-
vated or deactivated.
In the event of an accident, the central
locking system unlocks automatically
(only those doors which were not
locked separately with the safety lock
buttons). Refer to page 36. In addition,
the hazard warning flashers and interior
lamps come on.
To engage and release locksOne turn of the key in the driver's door
lock unlocks the driver's door only.
Turning the key a second time unlocks
all of the remaining doors, the luggage
compartment lid and the fuel filler door.
When a door is opened, the inte-
rior lamps and the exterior door
handle illumination are switched on.
Switching off is automatic.< 380de015
Convenience operating modeYou can also use your remote control
transmitter to open and close the elec-
tric power windows and the sliding/tilt
sunroof.
