    Head Restraints

    The vehicle’s front and rear seats have adjustable head restraints. The head restraints provide comfort for passengers, but more importantly they are designed to help protect passengers from whiplash and other neck and spinal injuries during an accident, especially in a rear impact collision.

    WARNING

    To reduce the risk of serious injury or death in an accident, take the following precautions when adjusting your head restraints:

    Always properly adjust the head restraints for all passengers BEFORE starting the vehicle. NEVER let anyone ride in a seat with the head restraints removed or reversed.
