If head restraints are not fitted or are adjusted incorrectly, they cannot provide protection as intended.
There is an increased risk of injury in the head and neck area, e.g. in the event of an accident or when braking.
Do not interchange the head restraints of the front and rear seats. Otherwise, you will not be able to adjust the height and angle of the head restraints correctly.
Adjust the head restraint fore-and-aft position so that it is as close as possible to the back of your head.
