Otherwise, exhaust fumes could penetrate
the interior of the vehicle. If special circum-
stances should make it absolutely neces-
sary to operate the vehicle with the luggage
compartment lid open:
>Close all windows. Shut the sliding/tilt
sunroof
>Increase the air supply of the automatic
climate control to a high level, refer to
page 101.< Manual operation(in the event of an electrical malfunction) Use the key to unlock the luggage
compartment lid, refer to page 38, and then
slowly open or close it, taking care to avoid
abrupt motion in the process.
Emergency release This lever releases the luggage compart-
ment lid from inside the luggage compart-
ment. Luggage compartmentNet*You can use the net to store smaller
objects on the bulkhead separating the
luggage compartment from the rear seats. Alarm system The conceptThe vehicle alarm system responds:
>When a door, the hood, or the luggage
compartment lid is opened
>To movement in the vehicle's interior Ð
interior motion sensor
>Changing the vehicle's tilt if someone
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 simul-
taneously activating:
>An acoustic alarm, which lasts for a
period of roughly 30 seconds

At a glanceControlsDriving tipsCommunicationsNavigationEntertainmentMobilityReference
41
>The hazard warning flashers for approx.
five minutes
>The high beams, which flash on and off
in the same rhythm.To arm and disarm the alarm system When you lock (or unlock) the vehicle,
either with the remote control unit or at the
door lock, the alarm system is armed (or
disarmed) at the same time.
The system indicates that is has been
correctly armed by switching on the hazard
warning flashers for a single cycle and by
emitting an acoustic signal.
You can have different acknowledg-
ment signals set to confirm arming
and disarming.<
Even with the alarm system armed, you can
open the luggage compartment lid using
the button 3on the remote control
unit, refer to page 36. The alarm system will
start to monitor the luggage compartment
lid again as soon as it is reclosed. Indicator lamp displays>The indicator lamp below the interior
rearview mirror flashes continuously: the
system is armed
>The indicator lamp flashes when the
system is armed: 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 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 manipulation or
attempted intrusions have been detected in
the period since the system was armed
>If the indicator lamp flashes for roughly
5 minutes when you disarm the system, or
until the remote control unit is inserted in
the ignition lock: an attempted entry has
been detected in the period since the
system was armed.
Following triggering of an alarm, the indi-
cator lamp will flash continuously.
Avoiding unintentional alarms The tilt alarm sensor and interior motion
sensor may be switched off at the same
time. You can do this 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, i. e., arm the alarm system
twice in a row by pressing button 2 on the
remote control unit twice in succession,
refer to page 36, or lock the vehicle twice
using the key, refer to page 37.
The indicator lamp flashes briefly and then
flashes continuously. The tilt alarm sensor
and the interior motion sensor are switched
off long as the system is armed.
If you desire, the

>tilt alarm sensor, and
>interior motion sensor
can be switched off permanently. Please
contact your BMW center for assistance.< Interior motion sensor In order for the interior motion sensor to
function properly, the windows and sliding/
tilt sunroof must be completely closed.
Be sure to deactivate the interior motion
sensor, see section on Avoiding uninten-
tional alarms, when you wish to leave the
windows or sliding/tilt sunroof open.

operation mode at the door lock or with the
remote control unit, refer to page 37 or 36. Safety featureIf the force rises beyond a predefined
threshold during closing, the system will immediately stop moving the window prior
to lowering it slightly.
Despite this safety feature you should
always inspect the window's travel
path prior to closing it, as the safety system
might fail to detect certain kinds of obstruc-
tions, such as very thin objects, and the
window would continue closing.
Pulling the switch beyond the pressure
point and holding it limits the response of
the safety feature. Under these conditions
the window will respond to forces beyond a
defined threshold by only opening several
millimeters.
If you again pull the switch past the pres-
sure point and hold it in position within a
period of roughly 4 seconds, the safety
feature will be deactivated.<
If you desire, you can have your BMW
center reprogram the safety feature
for deactivation the first time you pull and
hold the switch. Please contact your BMW
center for assistance.<

a short distance.
If you again press the switch past the pres-
sure point and hold it in position within
about 1.5 seconds, the safety feature will
be deactivated.<
When you close the sliding/tilt-
sunroof it will slow down as it
approaches the end of its travel path; this is
to allow the safety feature to respond more
precisely to any obstructions encountered
in this critical range.<
Following interruptions in electrical
power supply Following interruptions in electrical power
(for instance, when the battery is discon-
nected), it is possible that the sliding/tilt-
sunroof will extend to its tilt-up position,
but fail to respond to other commands.

Adjustments Correct sitting position

The ideal sitting position can make a vital
contribution to relaxed, fatigue-free driving.
The correct sitting position also works
together with the safety belts and airbags
to provide occupants with maximum levels
of passive safety in an accident. To ensure
that the safety systems operate with
optimal efficiency, we strongly urge you to
observe the instructions contained in the
following section.
For additional information on transporting
children safely, refer to page 57. Correct sitting position with airbags
Always maintain an adequate
distance between yourself and the
airbags. Always hold the steering wheel by
its rim with hands at the 9 o'clock and
3 o'clock positions, to minimize the risk of
injuries to your hands and arms in the event
of airbag deployment. No one and nothing
is to come between the airbags and the
seat occupant.
To prevent possible leg injuries should the
knee airbag deploy in an accident, ensure
that the front passenger assumes a correct
sitting position. Do not use the cover of the
front airbag on the front passenger side as
a storage area for objects, or as a rest for
feet or legs.<
For airbag locations and additional infor-
mation on airbags, refer to page 55.
Correct sitting position with safety
belts For the safety of all vehicle occupants,
please comply with the following instruc-
tions for wearing safety belts.
Never allow more than one person to
wear a single safety belt. Never allow
infants or small children to ride in a
passenger's lap. Avoid twisting the belt
while routing it firmly across the hips and
shoulder. Wear it as snugly against your body as possible. Do not allow the belt to
rest against hard or fragile objects.
Do not route the belt across your neck, or
run it across sharp edges. Be sure that the
belt does not become caught or jammed.
Avoid wearing loose or bulky clothing that
would prevent the belt from resting
securely against your body; pull on the
shoulder strap periodically to keep it
tensioned. In the event of a frontal impact,
a loose lap belt could slide over your hips,
leading to abdominal injury. In addition, the
safety belt's restraint effectiveness is
reduced if the belt is worn loosely.
Expectant mothers should always wear
their safety belts, taking care to position
the lap belt against the lower hips, where it
will not exert pressure against the abdom-
inal area.<
For putting on safety belts, refer to
page 50.
Seats For your personal safety when adjusting
the seat position, please follow the instruc-
tions below carefully.
Never attempt 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.
Never recline the backrest to an extremely
horizontal position while the vehicle is
underway Ð this precaution is especially
important for front passengers and the
occupants of electric power rear seats to
remember. Failure to observe these
precautions can prevent the belts from
providing effective protection against
injury, as passengers could slide under the
belts in an accident.<
Please observe the information on using
safety belts provided on page 50 and the
