Opening and closing Ð from the outsideWith the remote controlThe remote control makes opening and
locking the doors of your vehicle very
convenient. Furthermore, it provides
three additional functions which you
can only execute via the remote control:
>To switch on interior lamps:
With this function, you can also
"search for" your vehicle, when
parked in an underground garage, for
instance.
>To open the luggage compartment:
The luggage compartment lid/tail-
gate will open slightly, regardless 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 system is simultaneously deacti-
vated, the alarm system is disarmed
and the interior lamps are switched on.
Locking the vehicle activates the anti-
theft and alarm systems and switches
the interior lamps off.
You can have an acknowledgment
message set to confirm that the
vehicle has been secured correctly (not
released at this time).<
Master keysKeys with a transmitter for remote con-
trol are master keys. Refer to page 34.
Since children might be able to
lock the doors from the inside,
take the vehicle's keys with you so that
the vehicle can be opened again from
the outside at any time.< 390us604
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 bat-
tery 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 re-
mote control, surrender only the door
and ignition key 3 or the spare key 2
(refer to page 34) when leaving the ve-
hicle for valet parking, for example.
In the event of a system malfunction,
please contact your BMW center. You
can also obtain replacement keys
there.<

Opening and closing Ð from the insideYou can operate the central locking
system with this button when the
driver's door is closed. With this button,
only the doors, the luggage compart-
ment lid/tailgate and rear window are
unlocked or locked. The anti-theft sys-
tem is not activated. Also, the fuel filler
door remains unlocked to allow refuel-
ing.
The central locking system can be
locked automatically as soon as
you begin to drive if you desire. You
may also have this adjusted so that it is
specific to keys.< 390de016
If only the driver's door was un-
locked from the outside and you
press the button
>all other doors, the luggage compart-
ment lid/tailgate and rear window
and the fuel filler door will be un-
locked if the driver's door is open
>the driver's door will be locked again
when it is closed.<
To unlock and open the doors>Either unlock the doors together with
the button for the central locking sys-
tem 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.
Doors locked from outside can be
opened from inside by first press-
ing the button and then pulling a re-
lease handle twice.<
To engage locks>Use the central locking button to lock
all doors at once, or
>press the individual door lock buttons
down. As an added design feature to
prevent the driver from being inad-
vertently 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 their lock
buttons since doors locked in this man-
ner 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 car from the outside
at all times.<

Alarm systemThe conceptThe vehicle alarm system responds:
>When a door, the hood or the lug-
gage compartment lid/tailgate is
opened
>To movement inside the vehicle
(interior 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
activated for approx. five minutes
>The high beams flash on and off in
the same rhythm.
To activate and deactivate the
alarm systemWhen 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 fin-
ished locking the car.
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 messages set to confirm
arming and disarming (not released at
this time).<
When the system is active, you can still
gain access to the luggage compart-
ment by pressing button 3 on the
remote control transmitter (refer to
page 39). When you close the luggage
compartment lid/tailgate, it locks again.
Indicator lamp displays>The indicator lamp below the interior
rearview mirror flashes continuously:
The system is armed
>The indicator lamp flashes during
arming: Door(s), the hood or luggage
compartment lid/tailgate are not
completely closed. Even if you do not
close the alerted area, the system be-
gins to monitor the remaining areas,
and the indicator lamp flashes contin-
uously after 10 seconds. However,
the interior motion sensor is not acti-
vated
>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 armed390de020

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 alarmsThe 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:
Lock the vehicle (arm the alarm system)
twice in succession: Press button 2 on
the remote-control transmitter twice
(refer to page 38), or turn the key in the
door lock to the right (lock) twice in
succession (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 for as long as the
system remains armed.
Interior motion sensorThe illustration depicts the transmitter
and receiver of the interior motion sen-
sor.
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 (refer to the
previous column) if you intend to leave
the windows or sliding/tilt sunroof
open.390de153

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 window.390de055
After the ignition has been switched off:
>You can still operate the windows as
long as neither of the front doors has
been opened. To open the window,
press the switch beyond the resis-
tance point.
Remove the key from the ignition
when you leave the vehicle, so
that children cannot operate the power
windows and possibly injure them-
selves.<
For the convenience mode via the door
lock or the remote control, refer to
pages 36 or 37.Safety featureA contact strip is integrated into the
inner side of each of the upper window
frame sections. If pressure is exerted
against this contact strip while a win-
dow 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 (very thin objects, for
instance).
You can override this safety feature by
pressing the switch beyond the resis-
tance 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 be sure 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.<
