Alarm system
*
The conceptThe vehicle's alarm system responds:
>When a door, the hood or the
luggage compartment lid 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.
>If there is an 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 acti-
vated 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
by using a key or with the remote
control, the alarm system is also simul-
taneously armed or disarmed.
The interior motion sensor and the tilt
alarm sensor are activated approx.
30 seconds after you have finished
locking the vehicle.
If the alarm system has been armed
correctly, the hazard warning flashers
flash once.
You can have a signal set as
acknowledgment for both acti-
vating and deactivating the alarm.<
You can also open the luggage
compartment lid when the system is
armed by pressing button 3 of the
remote control (refer to page 37). When
it is closed, the lid is once again
secured.
Indicator lamp displaysThe indicator lamp is located under the
interior rearview mirror.
>When the indicator lamp flashes
continuously: the system is armed.
>If the indicator lamp flashes during
arming of the system: the door(s), the
hood or luggage compartment lid are
not completely closed. Even if you do
not close the alerted area, the system
begins to monitor the remaining
areas, and the indicator lamp flashes
continuously after 10 seconds.
However, the interior motion sensor
is not activated.
>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 armed.463us010

For your personal safety when adjusting
the seat position, please follow the
instructions below carefully:
Never try to adjust your seat while
operating the vehicle. The seat
could respond with an unexpected
movement, and the ensuing loss of
vehicle control could lead to an acci-
dent.
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.
Never ride with the backrest reclined to
an extreme angle (especially important
for the front passenger to remember).
If you do so, there is a risk that you will
slide under the safety belt in an acci-
dent, thus reducing the protection
provided by the safety belt.<
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 achieved
with your head extending from your
spine in a straight line. 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 54.1 Longitudinal 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.
2 Cushion height
Pull the lever and apply weight to or
remove weight from the seat as
required.

EMORY button acci-
dentally: press the button a second
time; the indicator lamp goes out.
Do not select a memory position
while the vehicle is moving. If you
do so, there is a risk of accident from
unexpected seat movement.<

Safety belts Airbags For child restraint system installation,
refer to page 61.
If the safety belt system has been
subjected to the stresses involved
in an accident or otherwise damaged:
have the entire safety belt mechanism
replaced by your BMW center,
including the safety belt tensioner. In
addition, have your BMW center
inspect the safety belt anchors. If a
child restraint system was in the vehicle
during an accident, consult the manu-
facturer's instructions regarding
replacement.<
Vehicles with through-loading
system: please comply with the
instructions for the center safety belt on
page 109.
Child restraint systems
*
Never install a rear-facing child
restraint device on the front
passenger seat. If you do so, the child
could be injured when the airbag is trig-
gered.
Children should always ride in the rear
and the restraint systems should be
secured with the outer belts.
The centre seat belt should only be
used when it is necessary to secure
three child restraint systems.
Do not modify the child restraint system
in any way. If you do so, it will not
provide your child with maximum
protection.<
1 Front airbags for driver and
passenger
2 Side impact Head Protection System
for driver and passenger (front)
3 Side airbags for driver and pasenger
(front and rear
*)
Protective effectThe front airbags supplement the three-
point safety belts by providing additional
protection for the front-seat occupants
in the event of a severe frontal collision
when the protection afforded by the
belts alone may no longer be sufficient.
The Side impact Head Protection
System and side airbags help provide
protection in the event of a side impact.
Each of the side airbags is designed to
help support the upper body.460de140

Transporting children safelyCommercially available child seats
complying with the legal standard are
designed to be secured with a lap belt
or with the lap belt portion of a combi-
nation 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.
If you use a child restraint system with a
tether strap, three additional tether
anchorage points (refer to the arrows in
the illustration) 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. Remove the
cover first on the middle location.380us123
If the respective seating position is
fitted with a headrest lift the headrest
and pass the tether strap between the
headrest and the seat back.
Adjust the tether strap according to the
child restraint manufacturer's instruc-
tions.
Before installing any child restraint
device or child seat, please read
the following:
Never install a rearward-facing child
restraint system in the front passenger
seat of this vehicle.
Your vehicle is equipped with an airbag
supplemental restraint system for the
front passenger. Because the backrest
on any rear-facing child restraint system
(of the kind designed for infants under
1 year and 20 lbs.) would be within the
airbag's deployment range, you should
never mount such a device in the front
passenger seat, since the impact of the
airbag against the child restraint's back-
rest could lead to serious or fatal inju-
ries.
If it is necessary for a child (not an
infant) to ride in the front seat, certain
precautions should be taken. First,
move the passenger seat as far away
from the dashboard as possible. This
important precaution is intended to
maximize the distance between the
airbag and the child. Older children
should be tightly secured with the safety
belt. Younger children should be
secured in an appropriate forward-
facing child restraint system that has
first been properly secured with a safety
belt.
Never install a rear-facing child restraint
system in the front passenger seat.
We strongly urge you to carefully read
and comply with the instructions for
installation and use provided by the
child restraint's manufacturer whenever
you use such a device.
Be sure that all occupants (of all ages)
remain properly and securely restrained
at all times.c
All rear seating positions in your
vehicle meet the recommendations of
SAE J1819, an industry recommended
practice for securing child restraint
systems in motor vehicles.
