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 which could cause
injury or discomfort to the child. ( P. 131)
■ 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 correctly fixed in place, the child or other
passengers 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 passenger seat or sec-
ond seats so that it does not interfere
with the child restraint system.
● Only put a forward-facing child restraint
system on the front seat when unavoid-
able. When installing a forward-facing
child restraint system on the front pas-
senger seat, move the seat as far back
as possible even if “AIR BAG OFF” indi-
cator light is illuminated. Failing to do
so may result in death or serious injury
if the airbags deploy (inflate).

CAUTION
■When installing a child restraint system
● When installing a child restraint system on the third center seat, adjust
both seatbacks at the same angle. Otherwise, the child restraint 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 using the LATCH anchors for a child restraint system, move the seat
as far back as possible (second seat only), with the seatback close to the
child restraint system.
● When a booster seat is installed, always ensure that the 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. 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 provided by the child restraint system
manufacturer.

CAUTION
■
When installing a child restraint s ystem to the AUTO ACCESS SEAT
(if equipped)
■ 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 sud-
den braking, sudden swerving or an accident.
■ To correctly attach a child r estraint 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. 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 braking, sudden swerving or an accident.
● Do not operate the AUTO ACCESS
SEAT while a child restraint system is
fixed to the seat by the child restraint
lock function belt.
If you force the seat operation, the seat,
seat belt or child restraint system may
be damaged, or may cause an injury.
● If a child restraint system is fixed to the
AUTO ACCESS SEAT by the LATCH
system, be careful that the child’s head,
hands and legs do not hit the body of
the vehicle when operating the seat.
Injuries may be caused.
