Alarm system
*
The conceptThe vehicle alarm system responds:
>When a door, the hood or the
luggage compartment lid is opened.
>To movement inside the vehicle (inte-
rior motion sensor).
>Altering the angle of the vehicle tilt
sensor, e. g. as would occur while
attempting to steal the wheels or tow
the vehicle (tilt sensor alarm system).
>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 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 simultaneously
armed or disarmed.
The interior motion sensor and the
alarm system tilt sensor are activated
approx. 30 seconds after the last door
has been locked.
If the alarm system has been armed
correctly, the hazard warning flashers
flash once.
You can have a signal set as
acknowledgment for both setting
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 34). When
it is closed, the lid is once again
secured.
Indicator lampThe indicator lamp is located under the
interior rearview mirror.
>When the indicator lamp flashes
continuously: the system is armed.
>The indicator lamp flashes when it is
armed: the door(s), the hood or
luggage compartment lid are not
completely closed. Even if you do not
close the alerted area, the remaining
areas are deadlocked, and the indi-
cator 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.

For maximum safety when adjusting the
seat position, please observe the
following:
Never try to adjust your seat while
operating the vehicle. The seat
could respond with 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.
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 posture To reduce strain on your 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 tilt-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 55. 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
seat engages securely.
2 Cushion height
Pull the lever and apply weight to or
remove weight from the seat as
required.

unexpected seat movement.<
Convenience function:
1 The driver's door remains open after
unlocking or the ignition key is in
position 1
2 Briefly press memory button 1, 2 or 3,
as desired.
Movement stops immediately when
one of the seat-adjustment or
memory buttons is activated during
the adjustment process.
Security function:

outside mirror positions when you
unlock the vehicle with your personal
remote control.<
If you make use of this method of
adjustment, be sure that the foot-
well behind the driver's seat is unob-
structed before unlocking the vehicle. If
you fail to do so, any persons or objects
behind the seat could be injured or
damaged by a rearward movement of
the seat.<

Safety beltsSafety belt height adjustmentYou can adjust the safety belts to fit
your own physical dimensions by using
the safety belt height adjustment.
Slide the button downward or upward.
For child restraint system installation,
refer to page 59.
For care instructions, refer to "Car care"
page 131.
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.<
Child restraint systems
*
Do not install a rear-facing child
restraint system in the front
passenger seat of your vehicle. If you
do so, the child could be injured in an
accident when the airbag is triggered.
Always transport children in the rear,
securing their restraint systems using
the outside safety belts.
Use the middle safety belt only if it is
necessary to install three child restraint
systems.
Do not modify the child restraint
systems in any way, as otherwise, their
protective function may be impaired.<

Transporting children safelyCommercially available child restraint
systems are designed to be secured
with a lap belt or with the lap belt
portion 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.
If you use a child restraint system with a
tether strap, three additional tether
anchorage points have been provided
(refer to the arrows in the illustration).
Depending on the location selected for
seating in the rear passenger area,
attach the strap hook to the corre-
sponding anchorage point to secure the
child restraint system. Remove the
cover first on the middle location.
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 rear-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/kg) would be
within the airbagÕs deployment range,
you should never mount such a device
in the front passenger seat, since the
impact of the airbag against the child
restraintÕs backrest could lead to
serious or fatal injuries.
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 instrument panel 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 manu-
facturer 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 prac-
tice for securing child restraint systems
in motor vehicles.

Transporting children safelyLATCH attachment of the child
seat
*
Remove the cover cap on the outer
mount by pulling it toward the front.
When reattaching it, make sure that the
recess points upward.
The illustration shows the mounts for a
LATCH child-restraint system on the
left rear seat.
To attach the LATCH child-
restraint system, please follow the
manufacturer's operating and safety
precautions.<< < <
Child seat securityAll of the rear belt retractors and the
front passenger's safety belt can be
locked for mounting and securing child
restraint systems.
A label with the appropriate instructions
for this is located in the immediate
vicinity of the buckle latch of each
safety belt.

Ski bag
*
The ski bag allows the safe and clean
transport of up to 4 pairs of standard
skis or up to two snowboards.
The length of the ski bag and the addi-
tional space provided in the luggage
compartment make it possible to carry
skis up to 6.8 ft long (2.1 0 meters).
Because of the tapered shape of the ski
bag, it can only accommodate two pairs
of skis 6.8 ft long (2.1 0 meters).
Loading1 Fold the center armrest outward.
Loosen the trim from the upper
Velcro¨ fastener and place it on the
armrest
2 Press button 1 downward and swing
the cover forward
3 Extend the ski bag between the
front seats. The zipper provides
convenient access to stored items.
It may be opened to allow the ski bag
to dry
4 Press knob 2: the cover in the
luggage compartment is unlocked.
To store the ski bag, perform the above
steps in reverse sequence.
Securing the loadSecure the bag's contents by tightening
down the retaining strap at the buckle.
Please be sure that the skis are
clean before loading them into the
bag. Be careful to avoid damage from
sharp edges.<

Cargo loading
Always position and secure the
load correctly. If you do not, it
can endanger the passengers during
braking or evasive maneuvers.
Do not exceed the permissible gross
weight and axle load (refer to
page 168), otherwise the vehicle's
operating safety is no longer assured
and you are in violation of the law.
Do not stow heavy or hard objects in
the passenger compartment without
first securing them. Otherwise they
would be thrown around during braking
and evasive maneuvers and endanger
the occupants.<
Stowing cargo If you are transporting a load in your
BMW:
>Load heavy cargo as far forward as
possible Ð directly behind the back-
rests or the luggage compartment
partition Ð and as low as possible
>Cover sharp edges and corners
>Do not pile objects higher than the
top edge of the backrest
>If you are transporting very heavy
loads when the rear seat is not
occupied, secure the outer safety
belts in the opposite buckles (refer
to the illustration).
