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.

WARNING
■When adjusting the seat position
● Take care when adjusting the seat position to ensure that other passen-
gers are not injured by the moving seat.
● Do not put your hands under the seat or near the moving parts t o avoid
injury.
Fingers or hands may become jammed in the seat mechanism.
■ Seat adjustment
● To reduce the risk of sliding under the lap belt during a collision, do not
recline the seat more than necessary.
If the seat is too reclined, the lap belt may slide past the hi ps and apply
restraint forces directly to the abdomen, or your neck may cont act the
shoulder belt, increasing the risk of death or serious injury in the event of
an accident.
Adjustments should not be made while driving as the seat may un expect-
edly move and cause the driver to lose control of the vehicle.
● Manual seat type only: After adjusting the seat, make sure that the seat is
locked in position.
■ When adjusting the seat positions
Make sure to leave enough space around the feet so they do not get stuck.
