the following while driving:
R adjust the driver's seat, head restraint,
steering wheel or mirrors
R fasten the seat belt
There is a risk of an accident.

led. Before driving off, make sure for every
vehicle occupant that the center of the head
restraint supports the back of the head at
about eye level.

the height and angle of the head restraints to
the correct position.
Using the fore-and-aft adjustment, adjust the head restraint so that it is as close as possible to your head.
