156 UNDERSTANDING THE FEATURES OF YOUR VEHICLE
When AHRs deploy during a rear impact, the front half
of the head restraint extends forward to reduce the gap
between the back of the occupant's head and the AHR.
This system is design to reduce the risk of injury to the
driver or front passenger in certain types of rear impacts.
Refer to "Occupant Restraints" in "Things To Know
Before Starting Your Vehicle" for further information.
To raise the head restraint, pull upward on the head
restraint. To lower the head restraint, push the adjust-
ment button, located at the base of the head restraint, and
push downward on the head restraint.
