of the head restraint supports the back of
the head at eye level. This will reduce the po-
tential for injury to the head and neck in the
event of an accident or similar situation.

head restraints. Head restraints are intend-
ed to help reduce injuries during an acci-
dent.

Adjust the head restraint in such a way that
it is as close to the head as possible.Warning!

For safety reasons, always drive with the
rear head restraints in the upright position
when the rear seats are occupied.
Keep the area around head restraints clear
of articles (e.g. clothing) to not obstruct the
folding operation of the head restraints.
