Rear seat head restraints
Warning!G
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint so that it is as
close to the head as possible and the center
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.
Warning!G
For safety reasons, always drive with the
rear head restraints in the raised position
when the rear seats are occupied.
Keep the area around head restraints clear
of articles (e.g. clothing) to not obstruct the
lowering/raising operation of the head
restraints.
