■Laws and regulations pertaining to anchorages
The LATCH system conforms to FMVSS225 or CMVSS210.2.
Child restraint systems conforming to FMVSS213 or CMVSS213 spec ifica-
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. 36)
■ 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.
● 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.
● Adjust the front passenger seat so that
it does not interfere 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 injur y 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 and backward
to ensure that it has been securely installed.
● Follow all installation instructions provided by the child rest raint system
manufacturer.
● When securing some types of child restraint systems 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 ef fectiveness. Be
sure your seat belt fits snugly across your shoulder and low on your hips. If
it does not, or if it interferes with the child restraint, move to a different
position. Failure to do so may result in death or serious injur y.
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 restraint system to the anchors
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.
