Head Restraints
The front seats have adjustable head restraints in the
outboard seating positions.
{CAUTION:
With head restraints that are not installed and
adjusted properly, there is a greater chance that
occupants will suffer a neck/spinal injury in a
crash. Do not drive until the head restraints for all
occupants are installed and adjusted properly.
Adjust the head restraint so that the top of the restraint
is at the same height as the top of the occupant’s head.
This position reduces the chance of a neck injury in a
crash.
