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 sever-
ity and type of the impact.
