1-2 Seats and Restraint System Head Restraints The vehicle's front seats have adjustable head restraints in all outboard seating positions. { CAUTION With head restraints that are not installed and adjusted properly, there is a greater chance that occupants will suffer a neck/spinal injury in a crash. Do not drive until the head restraints for all occupants are installed and adjusted properly. Adjust the head restraint so that the top of the restraint is at the same height as the top of the occupant's head. This position reduces the chance of a neck injury in a crash. Pull the head restraint up to raise it. To lower the head restraint, press the release button, located on the head restraint post on the top of the seatback, while you push the head restraint down. Push down on the head restraint after the button is released to make sure that it is locked in place.
