spinal injury in a crash. Do not
drive until the head restraints for
all occupants are installed and
adjusted properly.
If your vehicle has rear head
restraints that fold down, always
return them to the full upright
position whenever an occupant is
seated in the seat.
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.

position.
1.2. Put the child restraint on the seat.

if equipped. Refer to the child
restraint instructions and the
following steps:
2.1. Find the top tether
anchor.
2.2. Route, attach and tighten the top tether according
to your child restraint
instructions and the
following instructions:
.If the position you are using
does not have a headrest
