be easily stored in the luggage com-
partment.Installation1. Remove wind deflector from the pro-
tective sleeve

46To adjust
Safe seating positionFor driving that is relaxed and less likely
to cause fatigue, you should select a
sitting position that reflects your per-
sonal requirements. In combination
with the safety belts and airbags, the
correct seating position also plays an
important role in enhancing occupant
safety in the event of an accident. To
ensure that the vehicle's safety systems
provide you with optimal protection, we
request that you direct your careful
attention to the following section.
For supplementary information on
transporting children, refer to page 58.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 55.Sitting safely with safety beltsYour vehicle is equipped with four
seats, each of which is provided with a
safety belt.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.<
For information on using the safety
belts, refer to page 50.

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 horizontal angle
– important for front passengers to
remember. If you do so, there is a risk
that you will slide under the safety belt
in an accident, thus reducing the pro-
tection provided by the safety belt.
With the wind deflector in place:
Do not push the front seats all the way
back, otherwise the wind deflector will
be damaged.<

The seat can be locked into posi-
tion when it is tilted forward. This
is particularly convenient when entering
the vehicle on an incline, for example.
Press against the backrest until you
hear it snap into place. Lever 1 does
not have to be released to fold the seat
back.<
Lock both backrests while driving,
otherwise there is a danger of an
unexpected movement causing an
accident.<
The indicator lamp in the instru-
ment cluster flashes when the
backrest is not locked, refer to
page 18.
Safety beltsAlways wear your safety beltAlways fasten your safety belt before
starting off. As supplemental restraint
devices, the airbags are designed to
enhance the effectiveness of the safety
belts, and not to replace them.
Before putting your safety belts on
in the rear, take them out of the
holder.<
Leave the rear safety belts in the
holders if they are not needed, in
order to avoid unwanted movement
from the safety belts at high speeds. the belt buckle.
To release1. Press the red button in the belt
buckle
2. Hold the belt
3. Guide the belt back into its reel.Safety belt heightThe front safety belt automatically
adapts to your body size via the setting
of the head restraint height, refer to
page 48.
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, includ-
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.<
