point: the sunroof moves automati-
cally.
Tapping the switch again stops the

The headliner retracts with the sunroof
while it is opening.
After the ignition has been switched off,
you can still operate the sunroof for up
to 15 minutes, as long as no one opens
any of the doors.

any of the doors.
The headliner insert slides back some-
what when you raise the roof.
Do not use force to close the
headliner insert while the sunroof
is in its raised position, as damage to
the mechanism could result.<Safety featureIf the sliding/tilt sunroof encounters
resistance
>when it is closing from the raised
position
>when it is closing from a point
roughly past the middle of its travel,
the closing cycle is interrupted and the
sliding/tilt sunroof will open again
slightly.
Despite this safety feature, be
extremely careful to ensure that
the closing path of the sunroof is not
obstructed. Remember that the safety
mechanism may not be able to detect
obstructions – very thin objects, for
instance, under all circumstances.
You can override this safety feature by
pressing the switch beyond the pres-
sure point and holding it.<

43 To adjust
Safe seating positionFor relaxed and fatigue-free driving you
should select a sitting position that
reflects your personal requirements. In
combination with the safety belts and
airbags, the correct seating position
plays an important role in enhancing
occupant safety in the event of an acci-
dent. To ensure that the vehicle's safety
systems provide you with optimal pro-
tection, we request that you direct your
careful attention to the following sec-
tion.
For supplementary information on
transporting children, refer to page 55.Sitting safely with airbags
Always maintain an adequate dis-
tance between yourself and the
airbags. Always hold the steering wheel
by the rim to keep any chance of injury
to hands or arms to an absolute mini-
mum should the airbag be deployed.
Never allow any objects, individuals or
animals to obstruct the areas between
passengers and airbags. Never use the
front airbag's cover as a storage tray or
support for objects of any kind. Never
allow front passengers to rest their feet
or legs on the airbag cover.<
For airbag locations and additional
information on airbags, refer to
page 53.Sitting safely with 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
pelvis and shoulder, wear it as snugly
against your body as possible. Do not
allow the belt to rest against hard or
fragile objects in your pockets. 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 bulky clothing
and pull on the lap belt periodically to
retension it over your shoulders. 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. 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
abdominal area. Leave the rear safety
belts in the holders, if they are not
needed, to avoid unwanted movement
from the safety belts at high speeds.<
For information on using the safety
belts, refer to page 47.

SeatsWhen adjusting your seat, always
observe the following precautions
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. Never ride with the backrest
reclined to an extreme angle. This is
especially important for the front pas-
senger to remember. If you do so, there
is a risk that you will slide under the
safety belt in an accident, thus reducing
the protection provided by the safety
belt.<

ing the safety belt tensioner. In addi-
tion, have your BMW center inspect the
safety belt anchors. If a child-restraint
system was in the vehicle during an
accident, consult the manufacturer's
instructions regarding replacement.<
