KeysKey with radio remote control1 Master key with transmitter for radio
remote control.
2 Spare key for storage in a safe place,
such as your wallet. This key is not in-
tended for continuous use.
3 Door and ignition key
The locks for the luggage compart-
ment lid and glove compartment can-
not be operated with this key – this is
useful for valet parking, for instance.380us012
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.<

Luggage compartment lidThe lockOnly the master key (refer to page 30)
fits in the lock of the luggage compart-
ment.380de649
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. This feature can be
used to prevent unauthorized access to
the luggage compartment when you
surrender the door and ignition key (re-
fer to page 30) for valet parking, for in-
stance.380de650
Manual operation(in the event of electrical failure)
Turn the master key to the left in the
luggage compartment lock clear to the
stop – the luggage compartment lid will
open.
The luggage compartment is locked
again as soon as you close the lid.

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 in-
dicator lamp will flash continuously.Tilt alarm sensorThe tilt alarm sensor and interior motion
sensor may be switched off at the same
time. By doing this, you can prevent
false alarms on garage ramps or when
the vehicle is transported by trailer or
train, for instance.
Lock the vehicle twice (= arm the sys-
tem). In other words, press button 2 of
the remote control twice in succession
or lock the vehicle twice with the key.
The indicator lamp lights up briefly and
then flashes continuously. The tilt alarm
sensor and the interior motion sensor
are deactivated for as long as the sys-
tem remains armed.
Interior motion sensorThe transmitter and receiver of the inte-
rior motion sensor are located in a trim
panel in the vehicle's headliner.
In order for the interior motion sensor to
function properly, the windows and
sliding/tilt sunroof must be completely
closed.
Nevertheless, you should deactivate the
interior motion sensor whenever
>children or animals are left in the
vehicle
>the windows and/or sunroof are left
open.380de628
Emergency deactivation
procedureIf the car is locked and it is not possible
to disarm the system in the normal
manner, proceed as follows:
1 Use the key to unlock the door (the
alarm sounds for 30 seconds when
opening the door)
2 Turn the key to ignition key posi-
tion 1; the central locking system
unlocks the remaining doors.
The alarm system is now disarmed. Re-
fer the problem to your BMW center.

Electric power windowsOpen and close windowsIn ignition key position 1 or 2:
>Depress the rocker switch until you
feel resistance:
The window continues moving for as
long as you maintain pressure on the
switch
>Press the rocker switch beyond the
resistance point:
The window moves automatically.
Press the switch a second time to
stop the window380us651
After the ignition has been switched off:
>You can continue to operate the
power windows as long as one of the
front doors has not been opened. To
open a window, press the rocker
switch past the resistance point.
Remove the ignition key when you
leave the vehicle and close the
doors so that children can no longer
operate the power windows, possibly
injuring themselves, for instance.<
For the convenience operating mode
via the door lock or the remote control,
refer to page 32 or page 33.Safety featureA contact strip is integrated into each of
the upper window frame sections. 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 a small
distance.
Despite this safety feature, be ex-
tremely careful that the closing
path of the window is not obstructed
whenever it is closed. Otherwise, an
object might not touch the contact strip
in some situations (with very thin ob-
jects, for instance). You can override
this safety feature by pressing the
switch beyond the resistance point and
holding it.
Because the power windows are sealed
at high pressure to prevent wind noise
when closed, a powerful motor is re-
quired for efficient closing. When clos-
ing the windows, always ensure that
they are not obstructed in any way. Un-
supervised use of these systems can
result in serious personal injury. Re-
move the ignition key to deactivate the
electric power windows whenever you
leave the car. Never leave the keys in
the car with unsupervised children.
Never place anything that could ob-
struct the driver's vision on or next to
the windows.<

Sliding/Tilt sunroof
To prevent injuries, exercise care
when closing the sliding/tilt sun-
roof and keep it in your field of vision
until it is shut.
Before leaving the car, switch off the
electric sunroof mechanism by taking
out the ignition key. Do not leave
children unattended in the vehicle with
access to vehicle keys. Use of the key
can result in starting of the engine and
operation of vehicle systems such as
power sunroof, etc. Unsupervised use
of these systems can result in serious
personal injury.<
To avoid pressure or drafts in the pas-
senger compartment when the sunroof
is open or lifted, keep the air vents in
the dashboard open and increase
the air supply if necessary. Refer to
pages 100, 104.
For the convenience operating mode
via the door lock or the radio remote
control, refer to page 32 or page 33.
Safety featureIf the sliding/tilt sunroof encounters re-
sistance at a point roughly past the
middle of its travel when it is closing,
the closing cycle is interrupted and the
sunroof will open again slightly.
Despite this safety feature, be ex-
tremely careful that the closing
path of the sunroof is not obstructed
whenever it is closed. Otherwise, trig-
gering the closing-force limitation may
not be ensured in some situations (with
very thin objects, for instance). You can
override this safety feature by pressing
the switch beyond the resistance point
and holding it.<
Lifting – opening – closingFrom ignition key position 1 press the
switch or slide it to the desired direction
until you feel resistance.
When lifting, the headliner retracts sev-
eral inches.
You can continue to operate the sun-
roof after the ignition has been
switched off as long as one of the front
doors has not been opened.380de615
