■Laws and regulations pertaining to anchorages
Anchorages conform to FMVSS225 or CMVSS210.2. 
Child restraint systems conf orming to FMVSS213 or CMVSS213 specifications
can be used. 
This vehicle is designed to conform to the SAE J1819.
CAUTION
■When installing a booster seat
Do not fully extend the shoulder belt to prevent the belt from going to ALR lock
mode: ( P. 6 8 )
●ALR mode causes the belt to tighten only which could cause injury or discomfort
to the child.
●Do not allow the child to play with the seat belt or the child could be killed or seri-
ous injured.

CAUTION
■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 injured or even killed in the event of sudden braking or an accident.
●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 an accident or sudden braking.
●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.
●Only put a forward-facing child restraint
system on the front seat when unavoidable.
When installing a forward-facing child
restraint on the front passenger seat, move
the seat as far back as possible even if the
“AIR BAG OFF” indicator light is illumi-
nated. Failing to do so may result in death
or serious injury if the airbags deploy
(inflate).

CAUTION
■When installing a child restraint system
●Ensure the belt and tab are securely locked and that the seat belt is not twisted.
●Push and pull the child restraint system in different directions to be sure it is
secure.
●Follow all installation instructions provided 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 a collision.
■To correctly attach a child restraint system to the anchors
When using the lower 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 event of a sudden stop or accident.
