Head restraints are designed to reduce the risk of injury by
restricting head movement in the event of a rear impact.
Head restraints should be adjusted so that the top of the head
restraint is located above the top of your ear.

restraints are placed in their proper positions in order
to minimize the risk of neck injury in the event of a
crash.

restraints improperly adjusted or removed could cause
serious injury or death in the event of a collision.
