Head Restraints
Slide the head restraint up or down so that the top of the
restraint is closest to the top of your ears. This position
reduces the chance of a neck injury in a crash.
Pull up to raise the restraint.
To
lower it, push the
release button and push down.
Make sure the head restraint is locked in place after you
adjust it.
