Electronic vehicle immobilizer The key to securityYour BMW is equipped with a passive
anti-theft system. This electronic immo-
bilization system reduces the likelihood
of your vehicle being stolen by making
it impossible to start the engine using
any keys other than the ones furnished
with the vehicle. Your BMW center can
cancel the electronic system authoriza-
tion for individual keys (in the event of
loss, for instance). A deactivated key
can no longer be used to start the
engine.46cde060
How the electronics workAt the heart of this system is an elec-
tronic chip that is integrated into the
key. The lock mechanism itself is actu-
ally a dual-function device. While the
engine is running, the circuitry in the
ignition key and the vehicle's electronic
system constantly exchange variable,
vehicle-specific signals. The system will
not release the ignition, fuel injection
and starter unless it recognizes 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.<

Central locking system Opening and closing Ð from the outside The conceptThe central locking system is ready for
operation whenever the driver's door is
closed. The system engages and
releases the locks on the
>doors
>tailgate and rear window
>fuel filler door.
The central locking system can be
operated
>from outside via the door lock and
using the remote control
>from inside by pressing a button.
Activating the central locking system
from inside does not lock the fuel filler
door (see page 38). When it is actuated
from the outside, the anti-theft system
is activated simultaneously. Both the
door locks and release handles remain
locked. The alarm system is also armed
or disarmed.
If locked from the inside, the central
locking system unlocks automatically in
the event of an accident. But the system
only unlocks those doors that were not
locked separately using the safety
buttons, refer to page 38. In addition,
the hazard warning flashers and interior
lamps come on.
Using the keyOne 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 tailgate
and the fuel filler door.
You can have a signal set as an
acknowledgment message that
the vehicle is closed correctly.<460de006
Convenience operationYou can also operate the power
windows and sliding/tilt sunroof via the
door lock.
>To open: if the door is closed, hold
the key firmly in the "Unlock" posi-
tion.
>To close: if the door is closed, hold
the key firmly in the "Lock" position.
Watch during the closing process
to be sure that nobody is inadvert-
ently injured. Releasing the key stops
the operation. Turn the key to the extreme left or right
to unlock/lock the door.

Opening and closing Ð from the outside Using the remote controlThe remote control gives you an excep-
tionally convenient method for
unlocking and locking your vehicle.
Furthermore, it provides two additional
functions that only the remote control
can execute:
>Switching on the interior lamps, refer
to page 38.
With this function, you can also
"search for" your car Ð when parked
in an underground garage, for
instance.
>Opening the rear window, refer to
page 39.
The rear window will open slightly,
regardless of whether it was previ-
ously locked or unlocked.
When you unlock the vehicle, the anti-
theft system is deactivated, the alarm
system is disarmed, and the interior
lamps are turned on. When you lock the
vehicle, the systems are activated and
armed, and the lamps go 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 32.
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.<463de024
Master keys that are used repeat-
edly are always ready for opera-
tion since the battery in the key is
charged automatically in the steering
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 recharge the battery. Refer also to
page 32.
To prevent unauthorized use of the
remote control, surrender only the door
and ignition key or the spare key (refer
to page 32) 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.<

Alarm system
*
The conceptThe vehicle alarm system responds:
>When a door, the hood or the tailgate
is opened.
>To movement inside the vehicle
(interior motion sensor).
>To a change of the vehicle's tilt Ð if
someone attempts to steal the wheels
or tow the vehicle without authoriza-
tion, for example.
>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 flash 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 armed or
disarmed at the same time.
The interior motion sensor and tilt alarm
sensor are activated 30 seconds after
the last locking operation.
If the alarm system has been armed
correctly, the hazard warning flashers
flash once.
You can have one signal set as
acknowledgment when arming
and disarming.<
You can also open the rear window
when the system is armed by pressing
button 3 of the remote control (refer to
page 37). When it is closed, the rear
window is once again secured.
Indicator lamp displaysThe indicator lamp is located under the
inside rearview mirror.
>The indicator lamp flashes
continuously: the system is armed.
>The indicator lamp flashes when it
is armed: doors, the hood, tailgate
or rear window have not been prop-
erly closed. Even if you do not close
the alerted area, the remaining areas
are deadlocked, and the indicator
lamp flashes continuously after
10 seconds. However, the interior
motion sensor is not activated.
>The indicator lamp goes out when the
system is disarmed: no manipulation
or attempted intrusions have been
detected in the period since the
system was armed.463us010

Alarm system
*
>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 alarmsThe tilt alarm sensor and interior motion
sensor may be switched off at the same
time. Doing this prevents 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 (= arm the system)
twice. Press button 2 on the remote
control twice in succession or lock the
vehicle 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.
Reset the alarm system in order to
reactivate both the tilt sensor alarm
system and 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 (refer to the
previous column "Avoiding uninten-
tional alarms"), when you wish to leave
the windows or the tilt/sunroof open.460de159

Electric power windowsOpen and close the windowsFrom ignition key position 1:
>Press the switch up to but not past
the resistance point:
The window will continue to open as
long as you hold the switch.
>Press the switch past the resistance
point:
The window will move automatically.
Pressing the switch again stops the
opening cycle.
You can close the windows in the same
manner by pulling the switch.460de013
In the rear, there are separate switches
under the windows.
After the ignition has been switched off:
You can still operate the power
windows for up to 15 minutes, as long
as neither of the front doors was
opened during that time.
Remove the key from the ignition
and close the doors when you
leave the vehicle, so that children
cannot operate the power windows and
possibly injure themselves.<
For the convenience opening mode
with the door lock or remote control,
refer to page 34 or 35.
Safety feature A contact strip is located on the inside
upper frame of each of the windows. If
pressure is exerted against this contact
strip while a window is being raised, the
system will respond by stopping the
window and then retracting it some-
what.
Despite this safety feature, be
extremely careful that the closing
path of the window is not obstructed
whenever it is being closed. Otherwise,
an object might not touch the contact
strip in some situations (with very thin
objects, for instance).
You can override this safety feature by
pulling the switch beyond the resis-
tance point and holding it.<

Safety switch

With the safety switch, you can prevent
the rear windows from being opened or
closed via the switch in the rear
passenger area
* (by children, for
instance).
Press the safety switch whenever
children are riding in the rear of
the vehicle. Careless use of the power
windows can lead to injury.<
460de014
Exercise care when closing the
sliding/tilt sunroof and keep it in
your field of vision until it is completely
closed. Failure to do so can result in
injuries.
Always remove the key from the ignition
and lock the doors when you leave the
vehicle so that, for instance, children
cannot operate the sunroof and
possibly injure themselves.<
You can avoid a vacuum or drafts in the
passenger compartment whenever the
sunroof is open or raised if you keep the
air vents in the dashboard open and
increase the air supply as needed. Refer
to pages 92 or 99.
If the sunroof is completely open, air
disturbances may be caused in the
vehicle when you are driving at higher
speeds. Close the roof as far as is
necessary until this natural phenom-
enon ceases.
For the convenience opening mode
with the door lock or the remote
control, refer to page 34 or 35.
Lifting Ð opening Ð closingFrom ignition key position 1, press the
switch or slide it to the desired direction
until you feel resistance.
When lifting, the headliner retracts
several inches.
Do not use force to closethe
headliner when the sunroof is
open, or you could damage the
mechanism.<
After the ignition has been switched off,
you can still operate the sunroof for up
to 15 minutes, as long as neither of the
front doors was opened during that
time.460de015
