equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions and systems.
Sitting safely

the backrest on the front passenger side too far
to the rear during driving, or there is a risk of

Safety belts
Seats with safety belt
The vehicle has five seats, each of which is
equipped with a safety belt.
Number of safety belts
Your vehicle has been fitted with five safety belts
for the safety of you and your passengers. How‐
ever, they can only offer protection when ad‐
justed correctly.
Notes
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.▷The shoulder strap's anchorage point will be
correct for adult seat occupants of every
build if the seat is correctly adjusted.▷The two outer safety belt buckles,
integrated into the rear seat, are for passen‐
gers sitting on the left and right.▷The center rear seat belt buckle is solely in‐
tended for the center passenger.
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 im‐
pact and injure the abdomen.
The safety belt must not lie across the neck, rub
on sharp edges, be routed over solid or breaka‐
ble 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.◀
