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 portion of the
lap/shoulder belt.
■Installing child restraint
system using a seat belt
(child restraint lock func-
tion belt)
Install the child restraint system
in accordance to the operation
WARNING
●A forward-facing child restraint
system may be installed on the
front passenger seat only when
it is unavoidable. When install-
ing a forward-facing child
restraint system on the front
passenger seat, adjust the seat-
back angle to the most upright
position, move the seat to the
rearmost position, even if the
“PASSENGER AIR BAG OFF”
indicator light is illuminated.
If the head restraint interferes
with the child restraint system
installation and the head
restraint can be removed,
remove the head restraint.
●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 or rear
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 sys-
tem. It is dangerous if the SRS
side and curtain shield airbags
inflate, and the impact could
cause death or serious injury to
the child.
●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.
●Use a child restraint system
suitable to the age and size of
the child and install it to the rear
seat.
●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
so that it does not interfere with
the child restraint system.

1 Adjust the rear seat.
If there is a gap between the child
restraint system and the seatback,
adjust the seatback angle until
good contact is achieved.
2Place the child restraint sys-
tem on the rear seat facing
the rear of the vehicle.
3 Run the seat belt through the
child restraint system and
insert the plate into the

and allow it to retract to put it in lock mode. In lock mode,
the belt cannot be extended.
5 While pushing the child
restraint system down into
the rear seat, allow the shoul-
der belt to retract until the
child restraint system is
securely in place.
After the shoulder belt has
retracted to a point where there is
no slack in the belt, pull the belt to
check that it cannot be extended.
6After installing the child
restraint system, rock it back
and forth to ensure that it is
installed securely. ( P.59)

tether strap, follow the child
restraint manufacturer’s
operation manual regarding
the installation, using the top
tether strap to latch onto the
top tether strap anchor.
( P.62)
8 After installing the child
restraint system, rock it back
and forth to ensure that it is
installed securely. ( P.59)
■Booster seat
1 If installing the child restraint
system to the front passen-
ger seat is unavoidable, refer
to P.54for front passenger

rectly positioned over the child’s
shoulder and that the lap belt is as
low as possible. (P.31)
■Removing a child restraint
system installed with a seat
belt
Press the buckle release button
and fully retract the seat belt.
When releasing the buckle, the
child restraint system may spring
up due to the rebound of the seat
cushion. Release the buckle while
holding down the child restraint
system.
Since the seat belt automatically
reels itself, slowly return it to the
stowing position.
WARNING
■When installing a child
restraint system
Observe the following precau-
tions.
Failure to do so may result in
death or serious injury.
●Do not allow children to play
with the seat belt. If the seat belt
becomes twisted around a
child’s neck, it may lead to
choking or other serious injuries
that could result in death.
If this occurs and the buckle
cannot be unfastened, scissors
should be used to cut the belt.
●Ensure that the belt and plate
are securely locked and the
seat belt is not twisted.
●Shake the child restraint system
left and right, and forward and
backward to ensure that it has
been securely installed.
●After securing a child restraint
system, never adjust the seat.
●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.
●Follow all installation instruc-
tions provided by the child
restraint system manufacturer.

■Child restraint LATCH
anchors
LATCH anchors are provided for
the outboard rear seats. (Marks
displaying the location of the
anchors are attached to the seats.)
■When installing in the rear
outboard seats
Install the child restraint system
in accordance to the operation
manual enclosed with the child
restraint system.
1 If the head restraint interferes
with the child restraint system
installation and the head
restraint can be removed,
remove the head restraint.
( P.212)

WARNING
●When securing some types of
child restraint systems in rear
seats, it may not be possible to
properly use the seat belts in
positions next to the child
restraint without interfering with
it or affecting se at belt effective-
ness. 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, mo ve to a differ-
ent position. Failure to do so
may result in death or serious
injury.
■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
discomfort to the child. ( P.33)
■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 th e child restraint
system, which could cause death
or serious injury to the child or
other passengers in the event of
sudden braking, sudden swerv-
ing or an accident.

restraint system manufacturer’s
instructions permit use of those
anchors with the anchor spacing
stated.

621-2. Child safety
Child restraint systems with rigid
lower attachments cannot be
installed in the center seat. This
type of child restraint system
can only be installed in the out-
board seat.
■Laws and regulations pertain-
ing to anchors
The LATCH system conforms to
FMVSS225 or CMVSS210.2.
Child restraint systems conforming
to FMVSS213 or CMVSS213 speci-
fications can be used.
This vehicle is designed to conform
to SAE J1819.

WARNING
■When installing a child
restraint system
Observe the following precau-
tions.
Failure to do so may result in
death or serious injury.
●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 system.
●Follow all installation instruc-
tions provided by the child
restraint system manufacturer.
●Never attach two child restraint
system attachments to the
same anchor. In a collision, one
anchor may not be strong
enough to hold two child
restraint system attachments
and may break.
If the LATCH anchors are
already in use, use the seat belt
to install a child restraint system
in the center seat.
●When securing some types of
child restraint systems in rear
seats, it may not be possible to
properly use the seat belts in
positions next to the child
restraint without interfering with
it or affecting seat belt effective-
ness. 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 differ-
ent position. Failure to do so
may result in death or serious
injury.
●If the seat is adjusted, reconfirm
the security of the child restraint
system.
