Securing a child restraint seatwith "Tether Anchor" system
First secure the child restraint with
the LATCH lower anchors or the seat
belt. If the child restraint manufactur-
er recommends that the top tether
strap be attached, attach and tighten
the top tether strap to the top tether
strap anchor.
Child restraint hook holders are
located on the package tray. To install the tether anchor:
1. Route the child restraint tether strap
over the child restraint seatback.
Route the tether strap under the
head restraint and between the
head restraint posts, or route the
tether strap over the top of the vehi-
cle seatback. Make sure the strap is
not twisted.
2. Connect the tether strap hook to the tether anchor, then tighten the teth-
er strap according to the child seat
manufacturer's instructions to firmly
secure the child restraint to the seat.
3. Check that the child restraint is securely attached to the seat by
pushing and pulling the seat forward
and from side-to-side.
Take the following precautions
when installing the tether strap:
Read and follow all installation
instructions provided with
your child restraint system.
NEVER attach more than one
child restraint to a single teth-
er anchor. This could cause
the anchor or attachment to
come loose or break.
Do not attach the tether strap
to anything other than the cor-
rect tether anchor. It may not
work properly if attached to
something else.
Do not use the tether anchors
for adult seat belts or harness-
es, or for attaching other items
or equipment to the vehicle.

Securing a child restraint witha lap belt or lap/shoulder belt
When not using the LATCH system,
all child restraints must be secured to
a vehicle rear seat with the lap part
of a lap/shoulder belt.
Automatic locking mode
Since all passenger seat belts move
freely under normal conditions and
only lock under extreme or emer-
gency conditions (emergency locking
mode), you must manually pull the
seat belt all the way out to shift the
retractor to the "Automatic Locking"
mode to secure a child restraint.
The "Automatic Locking" mode will
help prevent the normal movement
of the child in the vehicle from caus-
ing the seat belt to loosen and com-
promise the child restraint system. To
secure a child restraint system, use
the following procedure. To install a child restraint system on
the rear seats, do the following:
1. Place the child restraint system on
a rear seat and route the lap/
shoulder belt around or through
the child restraint, following the
restraint manufacturer's instruc-
tions.
Be sure the seat belt webbing is
not twisted.
When using the rear center seat
belt, you should also refer to the
"3-point Rear Center Seat Belt"
section in this chapter.
NOTICE
ALWAYS place a rear-facing
child restraint in the rear seat of
the vehicle.
Placing a rear-facing child
restraint in the front seat can
result in serious injury or death
if the child restraint is struck by
an inflating air bag.

deploy only during certain side
impact collisions, depending on the
crash severity, angle, speed and
impact.
The side and curtain air bags on
both sides of the vehicle may deploy
