■Child restraint LATCH anchors
LATCH anchors are provided for the
outboard rear seats. (Buttons display-
ing the location of the anchors are
attached to the seats.)
■Installation with LATCH system
Install the child restraint system in
accordance to the operation manual
enclosed with the child restraint sys-
tem.
1 Adjust the seat
If there is a gap between the child seat and
the seatback, adjust the seatback until

tion and the head restraint can be

WARNING
●When securing some types of child
restraint systems in rear seats, it may
not be possible to properly use the
seat belts in position s next to the child
restraint without inte rfering 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 posi-
tion. Failure to do so may result in
death or serious injury.
●When installing a child restraint system
in the rear center seat, adjust both
seatbacks at the same angle. Other-
wise, the child restra int 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 shoul-
der belt. ALR mode causes the belt to
tighten only. This could cause injury or
discomfort to the child. ( P.28)
■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 sudden
braking, sudden swervi ng or an accident.

Observe the following precautions.
Failure to do so may result in death or
serious injury.
●Do not allow children to play in the lug-
gage compartment.
If a child is accidentally locked in the
luggage compartment, they could
have heat exhaustion or other injuries.
