such as your wallet. This key is not in-
tended for continuous use.

Replacement keysReplacement keys are available exclu-
sively through your authorized BMW
center. Your BMW center is obligated to
ensure that a person requesting a key is
authorized to do so since the keys be-
long to a security system (refer to "Elec-
tronic vehicle immobilizer" on page 31).

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

transmitter to open and close the elec-
tric power windows and the sliding/tilt
sunroof.

the key to the "Unlock" position and
hold it.
>To close: With the door closed, turn

Radio remote controlThe remote control makes opening and
locking the doors of your vehicle very
convenient. Furthermore, it provides
three additional functions which can
only be executed by means of the re-
mote control:
>Switching on the interior lamps and il-
luminating the exterior door handles.
With this function, you can also
"search for" your vehicle, when
parked in an underground garage, for
instance
>To open luggage compartment lid
The luggage compartment lid will
open slightly, regardless of whether
the lid was previously locked or un-
locked
>Panic Mode
In case of danger, you can trigger an
alarm.
The anti-theft system is also deacti-
vated/activated simultaneously with
the unlocking or locking of the vehicle,
and the alarm system is disarmed/
armed.
When the vehicle is unlocked, the inte-
rior lamps and the exterior door handle
illumination are switched on.

trol are master keys. Refer to page 30.
Since children might be able to
lock the doors from the inside,

the vehicle can be opened again from
the outside at any time.<
Every transmission is indicated by a
light signal. If the signal no longer lights

vehicle can be opened again from the
outside at any time.<
