Increase/decrease curvature
>Press the upper/lower end of the
switch:
Increase the upper/lower curvature.
Shoulder support:
Press the front/rear of the switch: the
support angle of the upper backrest
section is adjusted.
You can use the adjustable upper back-
rest for supplementary support in the
shoulder region. This provides a
relaxed seating position and helps
relieve stress on the shoulder muscles.
To obtain the optimal shoulder support
position, we recommend:
Driver and front passenger:
1. Adjust the upper backrest section to
its extreme rear position
2 Adjust for the optimal seating posi-
tion as described on page 48
3. Bring the upper backrest section
forward until your shoulders enjoy
firm support.

Front passenger's seat adjusted for
relaxed traveling:
1. Adjust the upper backrest section
to its extreme rear position
2. Lower the backrest slightly to
increase the tilt angle
3 Bring the upper backrest section
forward until your shoulders enjoy
firm support.
Make corrections in the forward/
backward adjustment of the seat
to ensure that the safety belt still fits
firmly against your body. Failure to
observe this precaution can reduce the
amount of protection provided by your
safety belt.<

head restraints, pull up or push down.
For electric height adjustment, refer to
page 50.
To adjust the angle of the front head
restraints, tilt to the desired angle.390de715
Head restraints reduce the risk
of spinal injury in the event of an
accident.
Adjust the head restraint so that its
center is approximately level with your
ears.
Leave the center-rear head restraint in
the fully-lowered position at all times.
Extending it limits its function.<
Active changes in the seat's cushion
help to avoid muscle cramps, pain in
the spine's lumbar region and fatigue.
To activate, press the button.390us725

Seat, mirror and steering wheel memory Seat heating
*
Your BMW center can adjust your
vehicle's systems in such a
manner that your personalized settings
are automatically called up for the seat,
mirror and steering wheel positions
when you unlock the vehicle with your
personal remote control key.<
Before using the key memory fea-
ture to unlock the vehicle always
ensure that no objects are stored in the
footwell behind the driver's seat. If you
fail to do so, persons or objects could
be injured or damaged if the seat
should move backward.<

tion
2 When the gearshift lever or the
selector lever is placed in "Reverse,"
the passenger-side mirror tilts down-
ward to help the driver monitor the
area directly adjacent to the vehicle
during parking (curbs, etc.).
You can deactivate this automatic fea-
ture by setting the mirror selector
switch to the "passenger-side" posi-
tion.390de720
The seat cushion and backrest can be
heated with the ignition key in

automatic dimming feature
*
These mirrors automatically respond to
glare from following vehicles by dim-
ming through an infinitely-variable
range. The mirrors automatically revert
to their clear, undimmed setting when-
ever you select reverse.
The dimming function is regulated by
two photocells; one is integrated in the
mirror's lens (arrow), while the other is
located at an offset position on the rear
of the mirror.
To ensure that the mirror continues to
operate efficiently, ensure that the pho-
tocells remain clear and unobstructed.
Refrain from attaching stickers to the
windshield in the area immediately in
front of the mirror.390de031

Airbags1 Front airbags on the driver and
passenger sides
2 Head protection airbags on driver
and passenger side (front and rear
*)
3 Side airbags on driver and passenger
side (front and rear
*)
Protective effectThe front airbags protect the driver and
passenger in the event of a head-on
collision where the protection provided
by the safety belt alone would not be
adequate. The head protection airbags
and side airbags help provide protec-
tion in the event of a collision from the
side. Each of the side airbags is
designed to help support the upper
body.380de643
The side airbags in the rear pas-
senger area
* of your vehicle may
already have been deactivated, either
at the time of manufacture or by a BMW
center. You may have them activated if
you desire to do so. Please contact
your BMW center for additional infor-
mation.c
For information on the correct seating
position, refer to page 48.
The airbags will not be triggered in
the event of a minor accident, a
vehicle rollover or a collision from the
rear.<

Airbags
Never apply stickers or adhesive-
backed objects of any kind to the
airbag covers. Never attempt to reup-
holster the covers or modify them in any
way. If the airbags deploy in response
to an accident, if you note any signs of
system malfunction, or if you wish to
have any parts of the airbag passenger-
restraint system deactivated, always
contact your BMW center, to whom we
strongly urge you to entrust all testing,
repair and dismantling operations.
Never attempt to modify or tamper with
either the system's electrical wiring or
any of its individual components.
System components include the uphol-
stered surfaces on the steering wheel,
instrument panel, the trim panels on the
front and rear doors and the roof braces
as well as the sides of the headliner
above the doors. Never attempt to
remove or dismantle the steering
wheel.
To ensure compliance with official
safety regulations, always entrust dis-
posal of airbag generators to your BMW
center. Attempts to carry out service
procedures undertaken by anyone
other than specially-trained profes-
sionals can result in system failure or
undesired airbag deployment, both of
which can lead to personal injury. If the
airbags deploy in response to an acci-
dent, always remember to avoid all
contact with system components, as
they are hot and can cause burns in the
period immediately following deploy-
ment.<
All vehicle occupants should
always sit upright and be properly
restrained (infants and small children in
appropriate child-restraint systems;
larger children and adults using the
safety belts). Never let an occupant's
head rest near or on a side airbag: the
inflating airbag could cause a serious or
fatal injury. Please note that the word
"Airbag" imprinted on the door trim
panel indicates the airbag's location.
Accident research shows that the
safest place for children in an automo-
bile is in the rear seat. However, a child
sitting in the rear seat and not properly
restrained may place his or her head on
or near the side airbag, if installed. For
example, a child Ð even though belted Ð
may fall asleep with his or her head
against the side airbag. It may be diffi-
cult for a driver to ensure that children
in the rear seat will remain properly
positioned at all times and do not place
their heads on or near the side airbag.
Therefore, we recommend that the
rear-seat side airbags, if provided, be
deactivated if you plan to transport chil-
dren in the rear seat.
The rear-seat side airbags may already
have been deactivated, either at the
time of manufacture or by a BMW
center. Labels in the rear door opening
should indicate the status of your rear-
seat side airbags. If you are uncertain of
their status, or wish to have the airbags
activated or deactivated, please con-
tact your BMW center.<
Even when all these guidelines are fol-
lowed, there is still a small residual risk
of injuries to the face, hands and arms
occurring in isolated instances.
The ignition and inflation noise may
provoke a mild temporary hearing loss
in extremely sensitive individuals.
Airbag warning information is also pro-
vided on the sun visors.
