Active head restraints (front seats)
If the vehicle detects an impact
during a rear-end collision, the front
part of the head restraint moves for-
ward and upward to help reduce the
risk of whiplash to the seat occu-
pant.
When reversing, even a small amount
of force applied from the rear, such as
a minor rear impact, may cause the
head restraints to move.
