Mitsubishi Lancer Owners Manual
To adjust height
Adjust the head restraint height so that the centre of the restraint is as close as possible to eye level to reduce the chances of injury in the event of collision.
Any person too tall for the restraint to reach their seated eye level, should adjust the restraint as high as possible.
To raise the head restraint, move it upward. To lower the restraint, move it downward while pushing the height adjusting knob (A) in the direction of the arrow. After adjustment, push the head restraint downward and make sure that it is locked.
