■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 on ly. This could cause injury or discomfort to
the child. ( P. 3 1 )
■When installing a child restraint system
Follow the directions given in the child restra int system installation manual and fix the
child restraint system securely in place.
If the child restraint system is not correctl y fixed in place, the child or other passengers
may be seriously injured or even killed in th e event of sudden braking, sudden swerving
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 sys-
tem on the front seat when unavoidable.
When installing a forward-facing child
restraint system on the front passenger seat,
move the seat as far back as possible even if
the “AIR BAG OFF” indicator light is illumi-
nated. Failure to do so may result in death or
serious injury if the airbags deploy (inflate).

■When installing a child restraint system
●When a booster seat is installed, always en sure that the shoulder 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 ch ild’s shoulder. Failing to do so may result in
death or serious injury in the event of sudden braking, sudden swerving or an acci-
dent.
●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.
●If the seat is adjusted, reconfirm the security of the child restraint system.
●Follow all installation instructions provided by the child restraint system manufacturer.
●When securing some types of child restraint systems in rear seat, it may not be possi-
ble to properly use the seat belts in positi ons next to the child restraint without inter-
fering with it or affecting se at belt effectiveness. 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
injury.
■Do not use a seat belt extender
If a seat belt extender is used when instal ling 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 sudden braking, sudden swerving or an
accident.
■To correctly attach a child re straint 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 securely attached , or it may cause death or serious injury to
the child or other passengers in the even t of sudden braking, sudden swerving or an
accident.
