WARNING
Child restraint anchorages are designed to
withstand only those loads imposed by cor-
rectly fitted child restraints. Under no cir-
cumstances are they to be used to attach
adult seat belts, or other items or equip-
ment to the vehicle. Doing so could damage
the child restraint anchorages. The child re-
straint will not be properly installed using
the damaged anchorage, and a child could
be seriously injured or killed in a collision.
FORWARD-FACING CHILD
RESTRAINT INSTALLATION
USING THE SEAT BELTS
WARNING
The three-point seat belt with Automatic
Locking Retractor (ALR) must be used
when installing a child restraint. Failure to
use the ALR mode will result in the child
restraint not being properly secured. The
restraint could tip over or be loose and
cause injury to a child in a sudden stop or
collision. Also, it can change the operation
of the front passenger air bag. For addi-
tional information, refer to “Front passen-
ger air bag and status light” in this section.

For additional information, refer to all Warn-
ings and Cautions in the “Child safety” and
“Child restraints” sections of this manual be-
fore installing a child restraint.
Do not use the lower anchors if the combined
weight of the child and the child restraint
exceeds 65 lbs. (29.5 kg). If the combined
weight of the child and the child restraint is
greater than 65 lbs. (29.5 kg), use the vehi-
cle’s seat belt (not the lower anchors) to in-
stall the child restraint. Be sure to follow the
child restraint manufacturer’s instructions for
installation.Follow these steps to install a forward-
facing child restraint using the vehicle seat
belt in the rear seats or in the front passenger
seat:
1. If you must install a child restraint in the
front seat, it should be placed in a
forward-facing direction only. Move
the seat to the rearmost position. Child
restraints for infants must be used in the
rear-facing direction and, therefore,
must not be used in the front seat.
2. Position the child restraint on the seat. Always follow the child restraint manu-
facturer’s instructions.
The back of the child restraint should be
secured against the vehicle seatback.
If necessary, adjust or remove the head
restraint/headrest to obtain the correct
child restraint fit. If the head
restraint/headrest is removed, store it in
a secure place. Be sure to reinstall the
head restraint/headrest when the child
restraint is removed. For additional in-
formation, refer to “Head
restraints/headrests” in this section. If the seating position does not have an
adjustable head restraint/headrest and
it is interfering with the proper child re-
straint fit, try another seating position or
a different child restraint.

3. Route the seat belt tongue through thechild restraint and insert it into the buckle
until you hear and feel the latch engage.
Be sure to follow the child restraint
manufacturer’s instructions for belt
routing.
If the child restraint is equipped with a
top tether strap, route the top tether
strap and secure the tether strap to the
tether anchor point (rear seat installation
only). For additional information, refer to
“Installing top tether strap” in this sec-
tion. Do not install child restraints that require
the use of a top tether strap in seating
positions that do not have a top tether
anchor.
4. Pull the shoulder belt until the belt is fullyextended. At this time, the seat belt re-
tractor is in the ALR mode (child restraint
mode). It reverts to ELR mode when the
seat belt is fully retracted.

5. Allow the seat belt to retract. Pull up onthe shoulder belt to remove any slack in
the belt. 6. Remove any additional slack from the
seat belt; press downward and rearward
firmly in the center of the child restraint
with your knee to compress the vehicle
seat cushion and seatback while pulling
up on the seat belt.
7. Tighten the tether strap according to the manufacturer’s instructions to remove
any slack. 8. After attaching the child restraint, test it
before you place the child in it. Push it
from side to side while holding the child
restraint near the seat belt path. The
child restraint should not move more
than 1 inch (25 mm), from side to side.
Try to tug it forward and check to see if
the belt holds the restraint in place. If the
restraint is not secure, tighten the seat
belt as necessary, or put the restraint in
another seat and test it again. You may
need to try a different child restraint. Not
all child restraints fit in all types of ve-
hicles.

killed in a sudden stop or collision greatly
increases: – Make sure the shoulder portion of the belt is away from the child’s face and
neck and the lap portion of the belt
does not cross the stomach.
– Make sure the shoulder belt is not be- hind the child or under the child’s arm.
– A booster seat must only be installed in a seating position that has a
lap/shoulder belt.

A. Low back booster seat
B. High back booster seatBooster seats of various sizes are offered by
several manufacturers. When selecting any
booster seat, keep the following points in
mind:∙ Choose only a booster seat with a label certifying that it complies with Federal
Motor Vehicle Safety Standard 213 or
Canadian Motor Vehicle Safety Standard
213.
∙ Check the booster seat in your vehicle to be sure it is compatible with the vehicle’s
seat and seat belt system. ∙ Make sure the child’s head will be prop-
erly supported by the booster seat or ve-
hicle seat. The seatback must be at or
above the center of the child’s ears. For
example, if a low back booster seat is
chosen, the vehicle seatback must be at
or above the center of the child’s ears. If
the seatback is lower than the center of
the child’s ears, a high back booster seat
should be used.
