Adjust your head restraint so that the top of the restraint is closest to the top of your head. This position reduces the chance of a neck injury in a crash.
To raise the head restraint pull up on the head restraint.
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 forward and rearward.
