Electric power windows
Despite this safety feature, be
extremely careful that the closing
path of the window is not obstructed.
Otherwise, an object might not touch
the contact strip in some situations
(very thin objects, for instance).
You can override this safety feature by
pressing the switch beyond the pres-
sure point and holding it.
Because the power windows are sealed
at high pressure to prevent wind noise
when closed, a powerful motor is
required for efficient closing. When
closing the windows, always ensure
that they are not obstructed in any way.
Unsupervised use of these systems can
result in serious personal injury.
Remove the ignition key to deactivate
the electric power windows whenever
you leave the vehicle. Never leave the
keys in the vehicle with unsupervised
children. Never place anything that
could obstruct the driver's vision on or
next to the windows.<
Safety switchWith the safety switch, you can prevent
the rear windows from being opened or
closed via the switch in the rear pas-
senger area (by children, for example).
Press the safety switch whenever
children are riding in the rear of
the vehicle. Careless use of the power
windows can lead to injury.< 390de693

Sliding/tilt sunroof
*
Despite this safety feature, be
extremely careful that the travel
path of the sunroof is not obstructed
whenever it is closed. Remember that
the safety mechanism may not be able
to detect obstructions under all circum-
stances (with very thin objects, for
instance). You can disable this safety
feature by pressing the switch beyond
the pressure point and holding it.<
Sliding/tilt sunroof with glass
moonroof
*
The options and control procedures are
essentially the same as those previ-
ously described for the sliding/tilt sun-
roof. In order to open the raised roof,
press the control switch towards
"Open" and maintain pressure until the
roof has reached the desired position.
The headliner insert slides back some-
what when you raise the sunroof, and
retracts along with the sunroof panel
when you slide it back. The insert then
remains open, and you can slide it back
and forth to adjust it whenever the sun-
roof is not fully retracted.
Interruption in the electrical
supplyAfter interruptions in the electrical
supply (when the battery is discon-
nected, for instance), the sunroof may
only lift. To reinitialize the mechanism:
1. Raise the sliding/tilt sunroof fully
2. Press and hold the switch for approx.
twenty seconds.390de725
Manual operationIn the event of an electrical malfunction,
you can also operate the sliding/tilt
sunroof manually:
1. Remove the interior lamp, then reach
into the exposed opening and press
out the cover
2. Use the Allen key from the onboard
tool kit (refer to page 152) to turn the
sliding/tilt sunroof in the desired
direction.390de376

>Press the front/rear of the switch:
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.<

If the safety belt system has been
subjected to the stresses involved
in an accident or otherwise damaged:
to ensure that the safety belts continue
to provide effective protection, always
have the entire safety belt mechanism
replaced and the belt anchorages
inspected at your BMW center.

Airbags1 Front airbags on the driver and
passenger sides

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.<
