How The Active Head Restraints (AHR) Work
The Occupant Restraint Controller (ORC)
determines whether the severity or type of rear
impact will require the Active Head Restraints
(AHR) to deploy. If a rear impact requires
deployment, both the driver and front
passenger seat AHRs will be deployed.
When AHRs deploy during a rear impact, the
front half of the head restraint extends forward
to minimize the gap between the back of the
occupant’s head and the AHR. This system is
designed to help prevent or reduce the extent of
injuries to the driver and front passenger in
certain types of rear impacts.
NOTE:
The Active Head Restraints (AHR) may or may
not deploy in the event of a front or side impact.
However, if during a front impact, a secondary
rear impact occurs, the AHR may deploy based
on the severity and type of the impact.

WARNING!
All occupants, including the driver, should
not operate a vehicle or sit in a vehicle’s seat
until the head restraints are placed in their
proper positions in order to minimize the risk
of neck injury in the event of a collision.
Do not place items over the top of the
Active Head Restraint, such as coats, seat
covers or portable DVD players. These
items may interfere with the operation of
the Active Head Restraint in the event of a
collision and could result in serious injury or
death.
Active Head Restraints may be deployed if
they are struck by an object such as a hand,
foot or loose cargo. To avoid accidental
deployment of the Active Head Restraint,
ensure that all cargo is secured, as loose
cargo could contact the Active Head
Restraint during sudden stops. Failure to
follow this warning could cause personal
injury if the Active Head Restraint is
deployed.
