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 unfa stened, 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 could 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 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. Failur e to do so may result in death or serious
injury. ●
When installing a child restraint system in the rear center seat, adjust both seat cush-
ions to the same position an d align both seatbacks at th e same angle. The seatbacks
must be adjusted to the sa me angle. Otherwise, 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 on ly. This could cause injury or discomfort to
the child. (  P. 3 2 )■
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.
