Head Restraints Adjust your head restraint so that the topof the restraint is closest to the top of your head. This position reduces the chance of a neck injury in a crash. The front seat head restraints are adjustable. Slide the head restraint up or down to adjust it. On some models, the head restraints tilt forward and rearward also. The rear seat head restraints in your vehicle may be adjustable. They work the same as the front seat head restraints, except they do not tilt forwardor rearward. 1-8
