HEAD RESTRAINTS
WARNING: To minimize the risk of neck injury in the event of a
crash, you and the passenger occupants should not sit in and/or
operate the vehicle, until the head restraint is placed in its proper
position. Never adjust the head restraint while the vehicle is in motion.
WARNING: The adjustable head restraint is a safety device.
Whenever possible it should be installed and properly adjusted
when the seat is occupied.
WARNING: Install the head restraint properly to minimize the
risk of neck injury in the event of a crash.
Note: Adjust the seatback to an upright driving position before adjusting
any head restraint. Properly adjust the head restraint so that the top of
the head restraint is even with the top of your head and positioned as
close as possible to the back of your head. For occupants of extremely
tall stature, adjust the head restraint to its full up position.
