■Laws and regulations pertaining to anchorages
The LATCH system conforms to FMVSS225 or CMVSS210.2.
Child restraint systems conforming to FMVSS213 or CMVSS213 specifica-
tions can be used.
This vehicle is designed to conform to the SAE J1819.
WARNING
■ When installing a booster seat
To prevent the belt from going into ALR lock mode, do not fully extend the
shoulder belt. ALR mode causes the belt to tighten only. This could cause
injury or discomfort to the child. ( P. 32)
■ When installing a child restraint system
Follow the directions given in the child restraint system insta llation manual
and fix the child restraint system securely in place.
If the child restraint system is not correctly fixed in place, the child or other
passengers may be seriously injured or even killed in the event of a sudden
braking or an accident.
● Vehicles with rear seats: If the driver’s
seat interferes with the child restraint
system and prevents it from being
attached correctly, attach the child
restraint system to the right-hand rear
seat.
● Vehicles with rear seats: Adjust the front
passenger seat so that it does not inter-
fere with the child restraint system.
● Only put a forward-facing child restraint
system on the front seat when unavoid-
able. When installing a forward-facing
child restraint system on the front pas-
senger seat, move the seat as far back
as possible even if the “AIR BAG OFF”
indicator light is illuminated. Failure to
do so may result in death or serious
injury if the airbags deploy (inflate).

WARNING
■When installing a child restraint system
● When a booster seat is installed, always ensure that the should er belt is
positioned across the center of the child’s shoulder. The belt should be
kept away from the child’s neck, but not so that it could fall off the child’s
shoulder. Failure to do so may result in death or serious injury in the event
of an accident or a sudden braking.
● Ensure that the belt and plate are securely locked and the seat belt is not
twisted.
● Shake the child restraint system left and right, and forward an d backward
to ensure that it has been securely installed.
● Follow all installation instructions provided by the child restraint system
manufacturer.
● Double Cab models only: When securing some types of child restraint sys-
tems in rear seats, it may not be possible to properly use the seat belts in
positions next to the child restraint without interfering with it or affecting
seat belt effectiveness. Be sure your seat belt fits snugly across your
shoulder and low on your hips. If it does not, or if it interfe res with the child
restraint, move to a different position. Failure to do so may result in death
or serious injury.
● Double Cab models only: When installing the child restraint system with
the head restraint being lowered, be sure to have the top tether strap pass
over the top of the head restraint. If the belt passes below the head
restraint, it is possible that the child restraint system may not be securely
fixed.
If the seat is adjusted, reconfirm the security of the child re straint system.
■ Do not use a seat belt extender
If a seat belt extender is used when installing a child restraint system, the
seat belt will not securely hold the child restraint system, which could cause
death or serious injury to the child or other passengers in the event of a sud-
den braking, sudden swerving or an accident.
■ To correctly attach a child restr aint system to the anchors (vehicles
with rear seats)
When using the LATCH anchors, be sure that there are no foreign objects
around the anchors and that the seat belt is not caught behind the child
restraint system. Make sure the child restraint system is secur ely attached,
or it may cause death or serious injury to the child or other p assengers in
the event of a sudden braking or an accident.
