Head Restraints - Chevrolet HHR 2011 Owner's Manual

Head Restraints

The front seats have adjustable head restraints in the
outboard seating positions.
WARNING:
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.
2-2
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.
