Adjusting the rear seat outer head restraints manually
WARNING Risk of injury due to incorrectly adjusted head restraints
If head restraints are not adjusted correctly, 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.
Before driving off, make sure for every vehicle occupant that the centre of the head restraint supports the back of the head at about eye level.
Do not interchange the head restraints of the front and rear seats. Otherwise, you cannot 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.
To move forwards:
pull the head restraint forwards. To move backwards:
press release knob 
and push the head restraint towards the rear.
