Safety information for chil-
dren
Observe the following precautions
when children are in the vehicle.
Use a child restraint system appro-
priate for the child, until the child
becomes large enough to properly
wear the vehicle’s seat belt.
It is recommended that children
sit in the rear seats to avoid acci-
dental contact with the shift lever,
wiper switch, etc.
 Use the rear door child-protector
lock or the window lock switch to
avoid children opening the door
while driving or operating the
power window accidentally.
( P.107, 143)
 Do not let small children operate
equipment which may catch or
pinch body parts, such as the
power window, hood, back door,
seats etc.
WARNING
■When children are in the vehicle
Never leave children unattended in the
vehicle, and never allow children to have
or use the key.
Children may be able to start the vehicle
or shift the vehicle into neutral. There is
also a danger that children may injure
themselves by playing with the windows,
the moon roof (if equipped) or other fea-
tures of the vehicle. In addition, heat
build-up or extremely cold temperatures
inside the vehicle can be fatal to children.

For safety and security
A child restraint system for a small
child or baby must itself be properly
restrained on the seat with the lap por-
tion of the lap/shoulder belt.
■Installing child restraint system
using a seat belt (child restraint
lock function belt)
Install the child restraint system in
accordance to the operation manual
enclosed with the child restraint sys-
tem.
■Rear-facing — Infant seat/convert-
ible seat
1 Adjust the seatback
If there is a gap between the child seat and
the seatback, adjust the seatback until
good contact is achieved.
WARNING
●Do not allow the child to lean his/her
head or any part of his/her body
against the door or the area of the seat,
front pillars or roof side rails from
which the SRS side airbags or SRS
curtain shield airbags deploy even if
the child is seated in the child restraint
system. It is dangerous if the SRS side
and curtain shield airbags inflate, and
the impact could cause death or seri-
ous injury to the child.
●When a booster seat is installed,
always ensure that th e 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.

it does not interfere with the child
restraint system.
●Do not allow the child to lean his/her
