Safety mode
Depending on vehicle equipment, the driver
and front passenger seat belt straps are auto-
matically tightened once after driving off, if the
seat belt is fastened.
If necessary, in critical driving situations, e.g.,
during emergency braking, the front seat belts
are automatically pretensioned.
After a critical driving situation without an acci-
dent, the front seat belts are loosened again. If
the belt tension does not loosen automatically,
stop the vehicle and unbuckle the seat belt us-
ing the red button in the buckle. Fasten the
seat belt before continuing to drive.
Front head restraints
Safety information
Warning
Removal or incorrect adjustment of head re-
straints can cause injuries in the head and
neck area. There is a risk of injury.
▷ Before driving, install the removed head
restraints on the occupied seats.
▷ Adjust the head restraint so its center
supports the back of the head at as
close to eye level as possible.
▷ Adjust the distance so that the head re-
straint is as close as possible to the back
of the head. Adjust the distance via the
backrest tilt as needed.
