Riding with children
Observe the following pre-
cautions when children are
in the vehicle.
Use a child restraint system
appropriate for the child,
until the child becomes
large enough to properly
wear the vehicle’s seat belt.
 It is recommended that chil-
dren sit in the rear seats to
avoid accidental contact
with the steering wheel,
wiper switch, etc.
Use the rear door child-pro-
tector lock or the window
lock switch to avoid children
opening the door while driv-
ing or operating the power
window accidentally.
( P.171, 214)
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 vehi-
cle
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 ma y injure them-
selves by playing with the side
windows or other features of the
vehicle. In addition, heat build-up
or extremely cold temperatures
inside the vehicle can be fatal to
children.

WARNING
●Toyota strongly urges the use of
a proper child restraint system
that conforms to the weight and
size of the child, installed on the
rear seat. According to accident
statistics, the child is safer when
properly restrained in the rear
seat than in the front seat.
●Holding a child in your or some-
one else’s arms is not a substi-
tute for a child restraint system.
In an accident, the child can be
crushed against the windshield
or between the holder and the
interior of the vehicle.
■Handling the child restraint
system
If the child restraint system is not
properly fixed in place, the child or
other passengers may be seri-
ously injured or even killed in the
event of sudden braking, sudden
swerving, or an accident.
●If the vehicle were to receive a
strong impact from an accident,
etc., it is possib le that the child
restraint system has damage
that is not readily visible. In
such cases, do not reuse the
restraint system.
●Make sure you have complied
with all installation instructions
provided with the child restraint
system manufacturer and that
the system is properly secured.
●Keep the child restraint system
properly secured on the seat
even if it is not in use. Do not
store the child restraint system
unsecured in the passenger
compartment.
●If it is necessa ry to detach the
child restraint system, remove it
from the vehicle or store it
securely in the luggage com-
partment.

For safety and security
install the child restraint system.
 Adjust the seatback angle to
the most upright position.
 Move the front seat fully rear-
ward. If the passenger seat
height can be adjusted, move
it to the upper most position.
 If the head restraint interferes
with the child restraint system
installation and the head
restraint can be removed,
remove the head restraint.
Otherwise, put the head
restraint in the upper most
position.
WARNING
■When using a child restraint
system
Observe the following precau-
tions.
Failure to do so m ay result in
death or serious injury.
●Never install a rear-facing child
restraint system on the front
passenger seat even if the “AIR
BAG OFF” indicator light is illu-
minated. In the event of an acci-
dent, the force of the rapid
inflation of the front passenger
airbag can cause death or seri-
ous injury to the child if the rear-
facing child restraint system is
installed on the front passenger
seat.
●A forward-facing child restraint
system may be installed on the
front passenger seat only when
it is unavoidable. A child
restraint system that requires a
top tether strap should not be
used in the front passenger seat
since there is no top tether strap
anchor for the front passenger
seat.
●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
“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.

5 While pushing the child
restraint system down into the rear seat, allow the shoul-
der belt to retract until the

check that it cannot be extended.
6 After installing the child
restraint system, rock it back
and forth to ensure that it is
installed securely. ( P.58)

When using the rear seat: If there is
a gap between the child restraint
system and the seatback, adjust
the seatback angle until good con-
tact is achieved.

restraint system. Fit the seat
belt to the child restraint sys-
tem according to the manu-
facturer’s instructions and
insert the plate into the
buckle. Make sure that the

Check that the sh oulder belt is cor-
rectly positioned over the child’s
shoulder and that the lap belt is as
low as possible. ( P. 2 9 )
■Removing a child restraint
system installed with a seat
belt
Press the buckle release button
and fully retract the seat belt.

child restraint system may spring
up due to the rebo und of the seat
cushion. Release the buckle while
holding down the child restraint

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 m ay 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.
●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. Fa ilure 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. 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.
