A child restraint system for a small child or baby must itself be properly
restrained on the seat with the lap portion of the lap/shoulder belt.
◆Installing child restraint system using a seat belt (child restraint lock func-
tion belt)
Install the child restraint system in accordance to the operation manual
enclosed with the child restraint system.
■Rear-facing — Infant seat/convertible seat
Adjust the rear seat
If there is a gap between the child se at and the seatback, adjust the seat-
back angle until good contact is achieved.
Place the child restraint system
on the rear seat facing the rear of
the vehicle.
Run the seat belt through the
child restraint system and insert
the plate into the buckle. Make
sure that the belt is not twisted.
Fully extend the shoulder belt and
allow it to retract to put it in lock
mode. In lock mode, the belt can-
not be extended.

Run the seat belt through the
child restraint system and insert
the plate into the buckle. Make
sure that the belt is not twisted.
Fully extend the shoulder belt and
allow it to retract to put it in lock
mode. In lock mode, the belt can-
not be extended.
While pushing the child restraint
system into the rear seat, allow
the shoulder belt to retract until
the child restraint system is
securely in place.
After the shoulder belt has retracted
to a point where there is no slack in
the belt, pull the belt to check that it
cannot be extended.
If the child restraint has a top tether strap, follow the child restraint manu-
facturer’s operation manual regarding the installation, using the top tether
strap to latch onto the top tether strap anchor. ( P. 70)
After installing the child restraint system, rock it back and forth to ensure
that it is installed securely. ( P. 66)

WARNING
■When installing a child restraint system
Observe the following precautions.
Failure to do so may result in death or serious injury.
●Do not allow children to play with the seat belt. If the seat belt becomes twisted
around a child’s neck, it may lead to chokin g or other serious injuries that could result
in death.
If this occurs and the buckle cannot be unfastened, scissors should be used to cut the
belt.
●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.
●After securing a child restraint system, never adjust the seat.
●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 coul d fall off the child’s shoulder.
●Follow all installation instructions provided by the child restraint system manufacturer.
●When securing some types of child restraint systems in rear seats, it may not be possi-
ble to properly use the seat belts in positions next to the child restraint without inter-
fering 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 interferes with the child
restraint, move to a different position. Failure to do so ma y result in death or serious
injury.
●When installing a child restraint system in th e rear center seat, adjust both seat cush-
ions to the same position an d align both seatbacks at the same angle. The seatbacks
must be adjusted to the same angle. Othe rwise, the child restraint system cannot be
securely restrained and this may cause death or serious injuries in the event of sudden
braking, sudden swerving or an accident.
■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. 33)
■Do not use a seat belt extender
If a seat belt extender is used when insta lling 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.
