Electronic vehicle immobilizer Central locking systemThe key to security Your BMW is equipped with a passive
antiÐtheft system. This electronic immo-
bilization system is designed to reduce
the susceptibility of your vehicle to theft
by making it impossible to start the
engine using any means other than the
special keys furnished with the vehicle.
Your BMW center can cancel the elec-
tronic system authorization for indi-
vidual keys (in the event of loss, for
instance). A deactivated key can no
longer be used to start the engine.
How the electronics work At 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
damage the integrated electronic
circuitry. A damaged key can no longer
be used to start the engine.<
The conceptThe system engages and releases the
locks on the:
>Doors
>Luggage compartment lid
>Fuel filler door.
The central locking system is ready for
operation whenever the driver's door is
closed. The central locking system can
be operated
>from outside via the door lock and
using the remote control
>from inside by pressing a button.
If it is operated from inside, the fuel
filler door will not be locked (refer to
page 36).
When the system is actuated from
outside the vehicle, the antitheft protec-
tion is simultaneously activated. Both
the door locks and release handles
remain locked. The alarm system is also
activated or deactivated.
For your safety: if locked from inside,
the central locking system unlocks
automatically in the event of an acci-
dent. In addition, the hazard warning
flashers and interior lamps come on.

Opening and closing Ð via the remote control The conceptThe remote control makes opening and
locking the doors of your vehicle very
convenient. Furthermore, it provides
two additional functions which you can
only execute via the remote control:
>Switch on the interior lamps, refer to
page 34.
With this function, you can also
"search" for your vehicle Ð when
parked in an underground garage, for
instance
>Open the luggage compartment lid.
Refer to page 34.
The luggage compartment lid will
open slightly, regardless of whether it
was locked or unlocked.
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,
and the interior lamps are switched on/
off.
You can have a signal set as an
acknowledgment message that
the vehicle is closed correctly.<
Master keysKeys with remote control are master
keys. Refer to page 30.
Children might be able to lock the
doors from the inside. For this
reason, always take the vehicle keys
with you so that the vehicle can be
opened again from the outside at any
time.<
Master keys that are used repeat-
edly are always ready for opera-
tion since the battery in the key is
charged automatically in the ignition
lock as you drive.
If it is no longer possible to unlock the
vehicle via the remote control, the
battery is discharged. Use this key
while driving for an extended period in
order to charge the battery. Refer also
to page 30.
Guard the remote control against unau-
thorized use by only surrendering the
spare key or the door key (refer to
page 30) e. g. for valet parking.
In the event of a system malfunction,
please contact your BMW center. You
can also obtain replacement keys
there.<

Lugagge compartment lidThe lock Only the master keys (refer to page 30)
fit in the lock for the luggage compart-
ment lid.
To secure separatelyTurn the master key to the right past the
resistance point and then pull it out in
the horizontal position.
This locks the luggage compartment lid
and disconnects it from the central
locking system. If you surrender only
the door key (refer to page 30), this will
prevent unauthorized access via the
luggage compartment lid. This is
convenient for valet parking, for
instance.

Lugagge compartment lidTo opening from the insideIf the luggage compartment lid has not
been locked separately, you can open it
with this button in the footwell on the
driver's side when the vehicle is
stationary.
To closeThe handle recesses in the interior trim
panel of the luggage compartment lid
(arrows) make it easier to pull the lid
down.
To avoid injuries, be sure that the
travel path of the luggage
compartment lid is clear when it is
closed, as with all closing procedures.<
Operate the vehicle only when the
luggage compartment lid is
completely closed. Otherwise, exhaust
fumes could penetrate the interior of
the vehicle. Should it be absolutely
necessary to operate the vehicle with
the luggage compartment lid open:
>Close all windows. Shut the sliding/
tilt sunroof.
>Increase the airflow of the automatic
climate control to a high level. Refer
to page 84.<

Alarm system
*
The conceptThe vehicle alarm system responds:
>When a door, the hood or the
luggage compartment lid is opened.
>To movement inside the vehicle (inte-
rior motion sensor).
>Altering the angle of the vehicle tilt
sensor, e. g. as would occur while
attempting to steal the wheels or tow
the vehicle (tilt sensor alarm system).
>To interruption of battery voltage.
The system responds to unauthorized
vehicle entry and attempted theft by
simultaneously activating the following:
>Sounding an acoustical alarm for
30 seconds.
>Activating the hazard warning
flashers for approx. five minutes.
>Flashing the high beams on and off in
rhythm with the hazard warning
flashers.
To activate and deactivate the
alarm systemWhen the vehicle is locked or unlocked
by using a key or the remote control,
the alarm system is also simultaneously
armed or disarmed.
The interior motion sensor and the
alarm system tilt sensor are activated
approx. 30 seconds after the last door
has been locked.
If the alarm system has been armed
correctly, the hazard warning flashers
flash once.
You can have a signal set as
acknowledgment for both setting
and deactivating the alarm.<
You can also open the luggage
compartment lid when the system is
armed by pressing button 3 of the
remote control (refer to page 34). When
it is closed, the lid is once again
secured.
Indicator lampThe indicator lamp is located under the
interior rearview mirror.
>When the indicator lamp flashes
continuously: the system is armed.
>The indicator lamp flashes when it is
armed: the door(s), the hood or
luggage compartment lid are not
completely closed. Even if you do not
close the alerted area, the remaining
areas are deadlocked, and the indi-
cator lamp flashes continuously after
10 seconds. However, the interior
motion sensor is not activated.
>If the indicator lamp goes out when
the system is disarmed: no manipula-
tion or attempted intrusions have
been detected in the period since the
system was armed.

Alarm system
*
>If the indicator lamp flashes for
10 seconds when the system is
disarmed: an attempted entry has
been detected in the period since the
system was armed.
Following triggering of an alarm, the
indicator lamp will flash continuously.Avoiding unintentional alarms The tilt alarm sensor and interior motion
sensor may be switched off at the same
time. You can do this to prevent a false
alarm from being triggered (in garages
with elevator ramps, for instance), or
when the vehicle is transported by
trailer or train:
Lock the vehicle twice (= setting the
alarm). Press button 2 on the remote
control twice in succession or lock the
vehicle twice with the key. Refer to
page 34.
The indicator lamp lights up briefly and
then flashes continuously. The tilt alarm
sensor and the interior motion sensor
are deactivated as long as the system is
armed.
Reset the alarm to reactivate the tilt
sensor alarm system and the interior
motion sensor.
Interior motion sensorThe transmitter and receiver of the inte-
rior motion sensor are located in a trim
panel in the vehicle's roof.
In order for the interior motion sensor to
function properly, the windows and
sliding/tilt sunroof must be completely
closed.
However, be sure to deactivate the
interior motion sensor (see "Avoiding
unintentional alarms") when you wish to
leave the windows or sliding/tilt sunroof
open.
