Adjusting the height: electrical
The head restraints on the left and right rear passenger seats extend automatically whenever a passenger in the rear seat fastens his or her safety belt.

In addition, the height of the head restraint can be adjusted electrically.
Extending the head restraint
To prevent possible personal injury and property damage, always ensure that the area above the head restraints is clear and unobstructed before extending them upward.
The height adjustment of the head restraint is deactivated when the safety switch for the rear windows, has been pressed.
