Alarm system*The conceptThe vehicle alarm system responds:
>When a door, the hood or the lug-
gage compartment lid is opened
>To movement inside the vehicle –
interior motion sensor
>To variations in the vehicle's tilt angle
such as those occurring during
attempts to steal the wheels or tow
the vehicle – tilt alarm sensor.
>To interruption of battery voltage.
The system responds to unauthorized
vehicle entry and attempted theft by
simultaneously activating the following:
>The acoustic alarm sounds for
30 seconds
>The hazard warning flashers are acti-
vated for approx. five minutes
>The high beams flash on and off in
rhythm with the hazard warning flash-
ers.To arm and disarm the alarm
systemWhen the vehicle is locked or unlocked
via the remote control or the driver's
door lock, the alarm system is also
simultaneously armed or disarmed.You can have different acknowl-
edgment signals set to confirm
arming and disarming.<

partment lid when the system is armed

Indicator lamp displays>The indicator lamp below the interior
rearview mirror flashes continuously:
the system is armed
>The indicator lamp flashes immedi-
ately after the vehicle is locked: doors
or luggage compartment lid are not
completely closed. Even if you do not
close the alerted area(s), the remain-
ing areas are secured, and the indi-
cator lamp will flash continuously
after 10 seconds. However, the inte-
rior motion sensor is not activated
>The indicator lamp goes out immedi-
ately after the vehicle is unlocked: no
manipulation or attempted intrusions
have been detected in the period
since the system was armed
>The indicator lamp flashes for
10 seconds immediately after the
system is armed: 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.Tilt alarm sensor and interior
motion sensorTilt alarm sensor:
The tilt of the vehicle is monitored. The
alarm system reacts, for example, to
attempts to steal the wheels or tow the
vehicle
Interior motion sensor:
In order for the interior motion sensor to
function properly, the windows and the
glass sunroof must be completely
closed.Avoiding unintentional alarmsThe tilt alarm sensor and interior motion
sensor may be switched off at the same
time. You can do this to prevent a false
alarm, e.g. in the following situations:
>In garages with elevator ramps
>When the vehicle is being trans-
ported by train
>When animals are to remain in the
vehicle.
To deactivate the tilt alarm and
interior motion sensors>Press the button on the remote con-
trol twice.
The indicator lamp lights up briefly and
then flashes continuously. The tilt alarm
sensor and the interior motion sensor
are deactivated until the vehicle is
unlocked and locked again.
You can have the tilt alarm sensor
and the interior motion sensor
permanently deactivated.<
The system inadvertently deacti-
vates the tilt alarm sensor and the
interior motion sensor if the conve-
nience closing of windows and glass
sunroof is interrupted within the first
10 seconds and then restarted. The
vehicle must then be unlocked and
relocked before the sensors will resume
operation.<

Transporting children safelyCommercially available child-restraint
systems are designed to be secured
with a lap belt or with the lap belt por-
tion of a combination lap/shoulder belt.
Improperly or inadequately installed
restraint systems can increase the risk
of injury to children. Always read and
follow the instructions that come with
the system.Correct location for installingIn your BMW, all seats equipped with a
three-point safety belt – except for the
driver's seat – are suitable for installing
universal child-restraint systems of all
age classes and which have been
approved for the age group in question.
Child-restraint system with
tether strapIf you use a child-restraint system with
a tether strap, three additional tether
anchorage points have been provided.
Depending on the location selected for
seating in the rear passenger area,
attach the tether strap to the corre-
sponding anchorage point to secure the
child-restraint system, as shown in the
illustration.
If the respective seating position is fit-
ted with a head restraint, lift the head
restraint, and pass the tether strap
between the head restraint and the seat
back.
It is recommended to readjust the head
restraint in the lowest possible position.
Adjust the tether strap according to the
child-restraint manufacturer's instruc-
tions.
