RESTRAINT INSTALLATION USING
LATCH
For additional information, see all Warnings
and Cautions in “Child safety” (P. 1-21) and
“Child restraints” (P. 1-23) before installing a
child restraint.
Do not use the lower anchors if the com-
bined weight of the child and the child re-
straint exceeds 65 lbs. (29.5 kg). If the com-
bined weight of the child and the child
restraint is greater than 65 lbs. (29.5 kg), use
the vehicle's seat belt (not the lower an-
chors) to install 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 LATCH
system: 1.
Type A (if so equipped):
Remove the plastic covers from the
LATCH anchors by pulling the covers
straight back. Store the covers in a se-
cure area.
Type B (if so equipped):

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. For additional infor-
mation, see “Installing top tether strap”
(P. 1-37). 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. 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 re-
straint is removed. For additional infor-

WARNING
Child restraint anchorages are de-
signed to withstand only those loads
imposed by correctly fitted child re-
straints. Under no circumstances are
they to be used to attach adult seat
belts, or other items or equipment to
the vehicle. Doing so could damage the
child restraint anchorages. The child
restraint 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 Auto-
matic 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 pas-
senger air bag. For additional informa-
tion, see “Front passenger air bag and
status light” (P. 1-57). For additional information, see all Warnings
and Cautions in the “Child safety” (P. 1-21)
and “Child restraints” (P. 1-23) before install-
ing a child restraint.
Do not use the lower anchors if the com-
bined weight of the child and the child re-
straint exceeds 65 lbs. (29.5 kg). If the com-
bined weight of the child and the child
restraint is greater than 65 lbs. (29.5 kg), use
the vehicle's seat belt (not the lower an-
chors) to install 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 passen-
ger 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

facturer’s instructions.
The back of the child restraint should be
secured against the vehicle seatback.

headrest is removed, store it in a secure
place. Be sure to reinstall the head
restraint/headrest when the child re-
straint is removed. For additional infor-
mation about head restraint/headrest
adjustment, removal and installation,
see “Head restraints/headrests” (P. 1-8). 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 re-
straint 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 installa-
tion only). For additional information, see
