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

Sliding/tilt sunroofAutomatic opening and closing>Press the switch past the resistance
point: the sunroof travels to either the
fully-closed or fully-opened position.
>With the sunroof open, press the
switch briefly toward "Raise": the roof
will move into the end "Raise" posi-
tion.
Pressing the switch again stops opera-
tion immediately.
Safety featureIf the sliding/tilt sunroof encounters
resistance 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
extremely 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 disable this safety feature by
pressing the switch beyond the pres-
sure point and holding it.<
Power loss or malfunctionIn the event of an electrical system
malfunction, the sliding/tilt sunroof can
be operated manually. Refer to
page 166.

For maximum safety when adjusting
the seat position, please observe the
following:
Never try to adjust your seat while
driving the vehicle. The seat could
respond with an unexpected move-
ment, and the ensuing loss of vehicle
control could lead to an accident.
Be sure that the safety belt remains
firmly against your body at all times. In
the event of a frontal impact, a loose lap
belt could slide over the hips, leading to
abdominal injury. In addition, the safety
belt's restraint effectiveness is reduced
if the belt is worn loosely.
While driving, do not recline the back-
rest too far (this applies to the
passenger side especially), because
otherwise there is the danger of sliding
underneath the safety belt during an
accident, thereby negating the safety
belt's protection.<
Correct sitting postureTo reduce strain on the spinal column,
sit all the way back in the seat and rest
your back fully against the backrest.
The ideal sitting posture is when your
head forms a straight line with your
spine.
For long-distance driving, you may wish
to increase the backrest angle slightly
to reduce muscular tension. You should
be able to grasp the steering wheel at
its highest point with your arms slightly
bent.
After a seat adjustment, adjust the
height of the safety belt also. Refer to
page 53.1 Backward/forward adjustment
Pull the lever and slide the seat to the
desired position.
After releasing the lever, apply pres-
sure to the cushion to ensure that the
latch engages securely

Adjusting steering wheel
Your BMW center can adjust your
vehicle's systems in such a
manner that your personalized settings
are automatically set for the seat and
outside mirror positions when you
unlock the vehicle with your personal
remote control.<
When this setting is used, be sure
that the footwell behind the
driver's seat is clear before unlocking
the vehicle. If you fail to do so, any
persons or objects behind the seat
could be injured or damaged by a rear-
ward movement of the seat.<
