For safety and security
WARNING
●Do not use seat accessories
which cover the parts where the
SRS side airbags and SRS seat
cushion airbag inflate as they
may interfere with inflation of
the SRS airbags. Such acces-
sories may prevent the side air-
bags and seat cushion airbag
from activating correctly, disable
the system or cause the side
airbags and seat cushion airbag
to inflate accidentally, resulting
in death or serious injury.
●Do not strike or apply significant
levels of force to the area of the
SRS airbag components or the
front doors.
Doing so can cause the SRS
airbags to malfunction.
●Do not touch any of the compo-
nent parts immediately after the
SRS airbags have deployed
(inflated) as they may be hot.
●If breathing becomes difficult
after the SRS airbags have
deployed, open a door or win-
dow to allow fresh air in, or
leave the vehicle if it is safe to
do so. Wash off any residue as
soon as possible to prevent skin
irritation.
●If the areas where the SRS air-
bags are stored, such as the
steering wheel pad and front
and rear pillar ga rnishes, are
damaged or cracked, have
them replaced by your Toyota
dealer.
●Do not place anything, such as
a cushion, on the front passen-
ger’s seat. Doing so will
disperse the passenger’s
weight, which prevents the sen-
sor from detecting the passen-
ger’s weight properly. As a
result, the SRS front airbags for
the front passenger may not
deploy in the event of a colli-
sion.
■Modification and disposal of
SRS airbag system compo-
nents
Do not dispose of your vehicle or
perform any of the following modi-
fications without consulting your
Toyota dealer. The SRS airbags
may malfunction or deploy
(inflate) accidentally, causing
death or serious injury.
●Installation, re moval, disassem-
bly and repair of the SRS air-
bags
●Repairs, modific ations, removal
or replacement of the steering
wheel, instrument panel, dash-
board, seats or seat upholstery,
front, side and rear pillars, roof
side rails, front door panels,
front door trims or front door
speakers
●Modifications to the front door
panel (such as making a hole in
it)
●Repairs or modifications of the
front fender, front bumper, or
side of the occupant compart-
ment
●Installation of a grille guard (bull
bars, kangaroo bar, etc.), snow
plows, winches or roof luggage
carrier
●Modifications to the vehicle’s
suspension system

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 shift lever, 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.116, 136)
 Do not let small children
operate equipment which
may catch or pinch body
parts, such as the power
window, hood, trunk, 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 win-
dows, the moon roof (if equipped)
or other features of the vehicle. In
addition, heat build-up or
extremely cold temperatures
inside the vehicle can be fatal to
children.

491-2. Child safety

For safety and security
WARNING
●For effective protection in auto-
mobile accidents and sudden
stops, a child must be properly
restrained, using a seat belt or
child restraint system which is
correctly installed. For installa-
tion details, ref er to the opera-
tion manual enclosed with the
child restraint system. General
installation instruction is pro-
vided in this manual.
●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.
●For Puerto Rico: Depending on
the child restraint system, instal-
lation may be difficult or impos-
sible. In those cases, check
whether the child restraint sys-
tem is suitable for installment in
the vehicle. (
P.55) Be sure to
install and observe the usage
rules after carefully reading the
child restraint system fixing
method in this manual, as well
as the operation manual
enclosed with the child restraint
system.
●Except for Puerto Rico: Make
sure you have complied with all
installation instructions provided
with the child restraint system
manufacturer and that the sys-
tem 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 necessary to detach the
child restraint system, remove it
from the vehicle or store it
securely in the trunk.

■When installing a child
restraint system to a front
passenger seat
For the safety of a child, install a
child restraint system to a rear
seat. When installing a child
restraint system to a front pas-
senger seat is unavoidable,
adjust the seat as follows and
install the child restraint system:
 Move the front seat fully rear-
ward.
 If the passenger seat height can be adjusted, Adjust the
seat height to the upper most
position.
 Adjust the seatback angle to
the most upright position.
If there is a gap between the child
seat and the seatb ack, adjust the
seatback angle until good contact is
achieved.
 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 mo st position.
