Safety belts
Seats with safety belt The vehicle has four seats, each of which is
equipped with a safety belt.
Hints
Always make sure that safety belts are being
worn by all occupants before driving away.
Although airbags enhance safety by providing
added protection, they are not a substitute for
safety belts.
One person per safety belt
Never allow more than one person to
wear a single safety belt. Never allow infants or
small children to ride on a passenger's lap.◀
Putting on the belt
Lay the belt, without twisting, snugly
across the lap and shoulders, as close to the
body as possible. Make sure that the belt lies
low around the hips in the lap area and does
not press on the abdomen. Otherwise, the belt
can slip over the hips in the lap area in a frontal
impact and injure the abdomen.
The safety belt must not lie across the neck,
rub on sharp edges, be routed over solid or
breakable objects, or be pinched.◀Reduction of restraining effect
Avoid wearing clothing that prevents the
belt from fitting properly, and pull the shoulder
belt periodically to readjust the tension across
your lap; otherwise, the retention effect of the
safety belt may be reduced.◀
Buckling the belt
Make sure you hear the latch plate engage in
the belt buckle.
Unbuckling the belt
1.Hold the belt firmly.2.Press the red button in the belt buckle.3.Guide the belt back into its reel.

and a signal sounds. Make sure that
the safety belts are positioned cor‐
rectly. The safety belt reminder is active at
speeds above approx. 5 mph/8 km/h. It can
also be activated if objects are placed on the
front passenger seat.
Damage to safety belts In the case of strain caused by accidents or
damage:
Have the safety belts, including the safety belt
tensioners, replaced and have the belt anchors checked.

is as close as possible to the back of the head.
Active head restraint In the event of a rear-end collision with a cer‐
tain severity, the active head restraint automat‐
ically reduces the distance from the head.
Reduced protective function▷Do not use seat or head restraint
covers.▷Do not hang objects, e.g., clothes hangers,
on the head restraints.▷Only attach accessories approved by BMW
to the seat or head restraint.
Otherwise, the protective function of the active
head restraint will be impaired and the per‐
sonal safety of the occupants will be endan‐
gered.◀
