CAUTION
■Child restraint precautions
●Make sure you have complied with all installation instructions provided by the
child restraint manufacturer and that the sy stem is properly secured. If it is not
secured properly, it may cause death or serious injury to the child in the event of a
sudden stop, sudden swerve or accident.
■Child restraint lock function belt precaution
Do not allow children to play with the child restraint lock function belt. If the belt
becomes twisted around a child’s neck, it will not be possible to pull the belt out
leading to choking or other serious in juries that could result in death.
If this occurs and the buckle cannot be un fastened, scissors should be used to cut
the belt.

●Keep the child restraint system properly secure d on the seat even if it is not in use.
Do not store the child restraint system unsecured in the passenger compartment.
●If it is necessary to detach the child restraint system, remove it from the vehicle or
store it securely in the trunk. This will prevent it from injuring passengers in the
event of a sudden stop, sudden swerve or accident.

1-8. Safety information
CAUTION
■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 discom-
fort to the child. (P. 7 5 )
■When installing a child restraint system
Follow the directions given in the child restraint 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 passen-
gers may be seriously injured or even killed in the 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 passen ger 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 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
illuminated. Failure to do so may result in
death or serious injury if the airbags deploy
(inflate).

Before driving
CAUTION
●When a booster seat is installed, always ensure that the shoulder belt is posi-
tioned 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. Failing to do so
may result in death or serious injury in the event of sudden braking, sudden
swerving or an accident.
●Ensure that the belt and plate are securely locked and the seat belt is not twisted.
●Push and pull the child restraint system from side to side and forward to be sure it
is secure.
●After securing a child restraint system, never adjust the seat.
●Follow all installation instructions provid ed by the child restraint system manufac-
turer.
■Do not use a seat belt extender
If a seat belt extender is used when inst alling 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 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 cau ght behind the child restraint. Make sure
the child restraint system is securely at tached, or it may cause death or serious
injury to the child or other passengers in the event of a sudden stop, sudden swerve
or accident.
