Overview
35nElectronic vehicle immobilizer
The key to security
Your BMW is equipped with a passive
anti-theft system. This electronic immo-
bilization system is designed to reduce
the susceptibility of the 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
electronic chip that is integrated into
the key. The lock mechanism itself is
actually 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. <

36nCentral locking system Opening and closing – from the outside
The concept
The central locking system is ready for
operation as soon as you close the front
doors. The system engages and
releases the locks on the
>doors
> liftgate/tailgate
> fuel filler door.
The central locking system can be
operated
> from outside via the driver's door lock
as well as via the remote control.
> from inside via the button for the
central locking system.
If the system is locked from inside, the
fuel filler door remains unlocked. Refer
to page 40.
When the system is actuated from
outside of the vehicle, the anti-theft
protection is actuated simultaneously.
The alarm system is also activated 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 40. In addition,
the hazard warning flashers and interior
lamps come on.
Using the key
One 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 liftgate/
tailgate and the fuel filler door.
You can have an acknowledgment
signal set to confirm that the
vehicle is correctly closed. <

Convenience operation
You can also operate the windows and
sliding/tilt sunroof via the door lock.
> To open: with the door closed, turn
the key to the "Unlock" position and
hold it.
> To close: with the door closed, turn
the key to the "Lock" position and
hold it.
Watch during the closing process
to be sure that no one is inadvert-
ently injured. Releasing the key stops
the operation. <
Manual operation
(in the event of an electrical malfunction)
Turn the key to the extreme left or right
to unlock/lock the door.

37nOpening and closing – from the outside
Using the remote control
The remote control offers you optimal
convenience in using your vehicle's
locking system while also providing
three exclusive supplementary features:
>Switch on the interior lamps, refer to
page 38.
With this function, you can also
"search for" your vehicle — when
parked in an underground garage, for
instance.
> Open the liftgate, refer to page 39.
The liftgate will open slightly, regard-
less of whether it was previously
locked or unlocked.
> Panic mode
In case of danger, you can trigger an
alarm.
When the vehicle is unlocked, the anti-
theft protection is deactivated and the
alarm system is disarmed; when the
vehicle is locked, the systems are acti-
vated or armed.
The interior lamps are switched on
when the vehicle is unlocked.
You can have an acknowledgment
signal set to confirm that the
vehicle is correctly closed. <
Master keys
Keys with remote control are master
keys. Refer to page 34.
Children might be able to lock the
doors from the inside. For this
reason, always take the vehicle's keys
with you so that the vehicle can be
opened again from the outside at any
time. <
530us011
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 lock 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 34.
To prevent unauthorized use of the
remote control, surrender only the door
and ignition key 3 or the spare key 2
(refer to page 34) when leaving the
vehicle for valet parking, for example.
In the event of a system malfunction,
please contact your BMW center. You
can also obtain replacement keys
there. <

The remote control system's func-
tioning may be affected by other units
or equipment operating in the imme-
diate vicinity of your vehicle.
If this should occur, you can unlock and
lock the vehicle via the door lock with a
master key.

To unlock and open the doors
> Either unlock the doors together with
the button for the central locking
system and then pull the door handle
above the armrest or
> pull the release handle for each door
twice: the first pull unlocks the door,
and the second one opens it.
To engage the locks
> Use the central locking button to lock
all of the doors simultaneously,
or
> press down the individual door lock
buttons. The fuel filler door remains
unlocked. As an added design
feature to prevent the driver from
being inadvertently locked out of the
vehicle, the driver's door lock button
will not engage as long as the door is
open.
When the vehicle is moving, do
not lock the doors with the safety
lock buttons. Doors locked in this
manner would not open automatically in
the event of an accident.
Children might be able to lock the
doors from the inside. For this reason,
you should always remove the key and
take it with you to be sure that you will
be able to unlock the vehicle from the
outside at all times. <

Overview
43nAlarm system
The concept
The vehicle alarm system responds:
>When a door, the hood, or the liftgate
is opened.
> To movement inside the vehicle (inte-
rior motion sensor).
> To variations in the vehicle tilt sensor
such as occur during attempts to
steal the wheels or tow the vehicle.
> 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.
> The hazard warning flashers are acti-
vated for approx. five minutes.
> The high beams flash on and off in
the same rhythm.
To activate and deactivate the
alarm system
When the vehicle is locked or unlocked
with the key or the remote control, the
alarm system is also simultaneously
armed or disarmed.
The interior motion sensor is activated
approx. 30 seconds after you have
finished locking the vehicle.
The system indicates that it has been
correctly armed by switching on the
hazard flashers for a single cycle and by
emitting an acoustical signal.
You can have different acknowl-
edgment signals set to confirm
system arming and disarming. <
You can still open the liftgate after the
system has been armed by pressing
button 3 of the remote control. Refer to
page 39. When you close the liftgate, it
is secured again.
Indicator lamp displays
> The indicator lamp below the interior
rearview mirror flashes continuously:
the system is armed.
> The indicator lamp flashes during
arming: a door(s), the hood or liftgate
are not completely closed. Even if
you do not close the alerted area, the
system begins to monitor the
remaining areas, and the indicator
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.

44nAlarm 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. 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:
Actuate the lock (= arm the system)
twice; in other words, press button 2 of
the remote control twice in succession
(refer to page 38). You may also actuate
the locks twice with the key (refer to
page 36).
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.
Interior motion sensor
The illustration depicts the transmitter
and receiver of the interior motion
sensor.
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 the previous
column) when you wish to leave the
windows or sliding/tilt sunroof open.
