94 Seats and Restraints
3. Tighten the top tether per the
child restraint manufacturer's
instructions.
When the top tether is properly
tightened, the anchor (loop)
may bend. This is normal and
will not damage the vehicle.
If child restraints are installed
in both outboard positions, both
top tethers can be attached to
the center loop. Top tethers
can be attached for child
restraints in all three rear
seating positions at the same
time, following the routing
instructions above.
4. Before placing a child in the
child restraint, make sure it is
securely held in place. To
check, grasp the child restraint
at the LATCH path and attempt
to move it side to side and
back and forth. There should
be no more than 2.5 cm (1 in)
of movement for proper
installation.
Headrest Removal and
Reinstallation
Removing Rear Headrests
For outboard rear seating positions,
if the child restraint cannot be
installed properly with the headrest
in place, the headrest may be
removed. See your dealer for
assistance with removal, and store
the removed headrests in a secure
place. When the child restraint is
removed, reinstall the headrest
before the seating position is used.
Reinstalling Rear Headrests
To reinstall the headrest:
1. Insert the headrest posts into
the holes in the top of the
seatback with the longer
chrome plated post toward the
driver side of the vehicle.
2. Push the headrest all the way
down until it contacts the top of
the seatback.

see your dealer to have the
system inspected and any
necessary replacements made as
soon as possible.
