To reinstall the adjustable head restraint, do the following:
1. Insert the two stems into the
guide sleeve collars.
2. Push the head restraint down
until it locks.
Properly adjust the head restraint so
that the top of the head restraint is even with the top of your head and
positioned as close as possible to the back of your head. For occupants
of extremely tall stature, adjust the head restraint to its full up position.
WARNING: To minimize the risk of neck injury in the event of a
crash, head restraints must be installed properly.
