∗1: The system judges a person of adult size as an adult. When a smaller adult sits in the front passenger seat, the system may
recognize him/her as a child depending on his/her physique and posture.
∗2: When a larger child who has outgrown a child restraint system sits in the front passenger seat, the system may recognize him/h er
as an adult depending on his/her physique or posture.
∗ 3: Never install a rear−facing child restraint system on the front passenger seat. A forward−facing child restraint system should only be
installed on the front passenger seat when it is unavoidable. (See Child restraint" on page 96 in this Section as for installi ng the
child restraint system.)

CAUTION
To avoid potential death or serious
injury when the front passenger occu-
pant classification system does not
detect the conditions correctly, ob-
serve the following.
Make sure the front passenger oc-
cupant classification indicator light
indicates ON" when using the seat
belt extender for the front passen-
ger seat. If the indicator light indi-
cates OFF", disconnect the extend-
er tongue from the seat belt buckle,
then reconnect the seat belt. Recon-
nect the seat belt extender after
making sure the indicator light indi-
cates ON". If you use the seat belt
extender while the indicator light
indicates OFF", the front passen-
ger airbag and side airbag on the
front passenger side may not acti-
vate correctly, which could cause
death or serious injury in the event
of collision.
Do not recline the front passenger
seatback so far that it touches a
second seat. This may cause the
OFF" indicator to be illuminated,
which indicates that the passen-
ger’s airbags will not deploy in the
event of a severe accident. If the
seatback touches the rear/second
seat, return the seatback to a posi-
tion where it does not touches the
rear/second seat.
Keep the front passenger seatback
as upright as possible when the ve-
hicle is moving. Reclining the seat-
back excessively may lessen the ef-
fectiveness of the seat belt system.
If an adult sits in the front passen-
ger seat, the occupant classification
indicator light should indicate ON".
If the OFF" indicator is illumina-
ted, ask the passenger to sit up
straight, well back in the seat, feet
on the floor, and with the seat belt
worn correctly. If the OFF" indica-
tor still remains illuminated, either
ask the passenger to move to the
rear/second seat, or if that is not
possible, move the front passenger
seat fully rearward.
Wear the seat belt properly.
Make sure the front passenger’s
seat belt tab has not been left in-
serted into the buckle before some-
one sits in the front passenger
seat.
Do not apply a heavy load to the
front passenger seat.
Do not put weight on the front pas-
senger seat by putting your hands
or feet on the front passenger seat
seatback from the rear/second pas-
senger seat.
Do not let a rear/second passenger
lift the front passenger seat with
their feet or press on the seatback
with their legs.
Do not put objects under the front
passenger seat.
Child restraint systems installed on
the rear/second seat should not
contact the front seatbacks.

95
When it is unavoidable to install the
forward−facing child restraint sys-
tem on the front passenger seat,
install the child restraint system on
the front passenger seat in the
proper order. (As for the installation
order, see Installation with seat
belt" on page 99 in this Section.)
Do not remove the front seats.
Do not kick the front passenger
seat or subject it to severe impact.
Otherwise, the SRS warning light
may come on to indicate a malfunc-
tion of the detection system. In this
case, contact your Toyota dealer im-
mediately.
The front passenger occupant classifica-
tion indicator light may indicate ON" (the
front passenger airbag and side airbag on
the front passenger seat may deploy)
even if observing the above cautions,
when a child sits in, or a forward−facing
child restraint system is installed on the
front passenger seat. Refer to all the cau-
tions in SRS airbags" on page 74 and
Child restraint" on page 96 in this Sec-
tion.
CY13302
The roll sensing of curtain shield air-
bags off switch (RSCA OFF" switch)
can turn off the curtain shield airbags
and seat belt pretensioners in a vehicle
rollover. This switch should only be
used if inflation is not desired (such as
extreme off−road driving).When you push the RSCA OFF" switch
for a few seconds with the engine switch
on, the RSCA OFF" indicator light comes
on and the roll sensing function is turned
off. When you push the switch again, the
indicator light goes off and the roll sens-
ing function is turned on. (For details
about the roll sensing function, see
SRS side airbags and curtain shield
airbags" on page 81 in this Section.)
In a severe side impact, the curtain shield
airbags on impacted side will inflate even
if the roll sensing function is turned off.
(For details about the curtain shield air-
bags, see SRS side airbags and curtain
shield airbags" on page 81 in this Sec-
tion.)
In a severe frontal impact, the seat belt
pretensioners will work even if the roll
sensing function is turned off. (For details
about the seat belt pretensioners, see
Seat belt pretensioners" on page 71 in
this Section.)
If the engine switch is turned to ACC" or
LOCK" with the roll sensing function off
and then the engine switch is turned back
to ON", the roll sensing function will turn
back on automatically.
Roll sensing of curtain shield
airbags off switch

96
CAUTION
Before normal driving, make sure
the RSCA OFF" indicator light is
off.
When the roll sensing function is
turned off (and the RSCA OFF"
indicator light is on), the curtain
shield airbags and seat belt preten-
sioners will not work in a vehicle
rollover. Turning off the curtain
shield airbags and seat belt preten-
sioners reduces occupant protection
which your vehicle safety systems
can provide in accidents and in-
crease the likelihood of death or
serious injuries.
Toyota strongly urges the use of ap-
propriate child restraint systems for
children.
The laws of all 50 states in the U.S.A.
and Canada now require the use of a
child restraint system.
Your vehicle conforms to SAE J1819.
If a child is too large for a child restraint
system, the child should sit in the rear
seat and must be restrained using the
vehicle’s seat belt. See Seat belts" on
page 64 in this Section for details.
CAUTION
For effective protection in automo-
bile accidents and sudden stops, a
child must be properly restrained,
using a seat belt or child restraint
system depending on the age and
size of the child. Holding a child in
your arms is not a substitute for a
child restraint system. In an acci-
dent, the child can be crushed
against the windshield, or between
you and the vehicle’s interior.
Toyota strongly urges use of a
proper child restraint system which
conforms to the size of the child,
and is installed on the rear seat.
According to accident statistics, the
child is safer when properly re-
strained in the rear seat than in the
front seat.
Never install a rear−facing child re-
straint system on the front passen-
ger seat even if the front passenger
occupant classification indicator
light indicates OFF". In the event
of an accident, the impact of the
rapid inflation of the front passen-
ger airbag could cause death or se-
rious injury to the child if the rear−
facing child restraint system is
installed on the front passenger
seat.
Child restraint
Child restraint precautions

97
A forward−facing child restraint sys-
tem should be allowed to be
installed on the front passenger
seat only when it is unavoidable.
Always move the seat as far back
as possible even if the front pas-
senger occupant classification indi-
cator light indicates OFF", because
the front passenger airbag could in-
flate with considerable speed and
force. Otherwise, the child may be
killed or seriously injured.
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 pillar or
roof side rail from which the side
airbags or curtain shield airbags
deploy even if the child is seated in
the child restraint system. It is dan-
gerous if the side airbag and/or
curtain shield airbag inflate, and the
impact could cause death or seri-
ous injury to the child.
Do not use the seat belt extender
when installing a child restraint
system on the front or rear passen-
ger seat. If installing a child re-
straint system with the seat belt
extender connected to the seat belt,
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 collision.
Make sure you have complied with
all installation instructions provided
by the child restraint manufacturer
and that the system is properly se-
cured. If it is not secured properly,
it may cause death or serious injury
to the child in the event of a sud-
den stop or accident.
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. You must
carefully consult the manufacturer ’s
instructions which accompany the child
restraint system.
To provide proper restraint, use a child
restraint system following the manufactur-
er ’s instructions about the appropriate age
and size of the child for the child restraint
system.
Install the child restraint system correctly
following the instructions provided by its
manufacturer. General directions are also
provided under the following illustrations.
The child restraint system should be
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.
When not using the child restraint system,
keep it secured with the seat belt or place
it somewhere other than the passenger
compartment. This will prevent it from in-
juring passengers in the event of a sud-
den stop or accident.
Child restraint system

98
Child restraint systems are classified into
the following 3 types depending on the
child’s age and size.
(A) Infant seat
(B) Convertible seat
(C) Booster seat
Install the child restraint system following
the instructions provided by its manufac-
turer.
Your vehicle has anchor brackets for se-
curing the top strap of a child restraint
system.
For instructions about how to use the an-
chor bracket, see Using a top strap" on
page 109 in this Section.
The child restraint lower anchorages
approved for your vehicle may also be
used. See Installation with child
restraint lower anchorages" on page 114 in
this Section.

(A) INFANT SEAT INSTALLATION
An infant seat must be used in rear−
facing position only.
CY13034
CAUTION
Never install a rear−facing child re-
straint system on the front passen-
ger seat even if the front passenger
occupant classification indicator
light indicates OFF". In the event
of an accident, the impact of the
rapid inflation of the front passen-
ger airbag could cause death or se-
rious injury to the child if the rear−
facing child restraint system is
installed on the front passenger
seat.
CY13035
Do not install a child restraint sys-
tem on the second (or third) seat if
it interferes with the lock mecha-
nism of the front (or second) seats.
Otherwise, the child or front (or
second) seat occupant(s) may be
killed or seriously injured in case
of sudden braking or a collision.
If the driver’s seat position does
not allow sufficient space for safe
installation, install the child re-
straint system on the rear right
seat.

CY13167
To install the infant seat:1. Run the lap and shoulder belt through or around the infant seat following the
instructions provided by its manufactur-
er and insert the tab into the buckle
taking care not to twist the belt. Keep
the lap portion of the belt tight.
CAUTION
After inserting the tab, make sure
the tab and buckle are locked and
that the lap and shoulder portions
of the belt are not twisted.
Do not insert coins, clips, etc. in
the buckle as this may prevent your
child from properly latching the tab
and buckle.
If the seat belt does not function
normally, it cannot protect your
child from death or serious injury.
Contact your Toyota dealer immedi-
ately. Do not install the child
restraint system on the seat until
the seat belt is fixed.
CY13157
2. Fully extend the shoulder belt to put itin the lock mode. When the belt is
then retracted even slightly, it cannot
be extended.
To hold the infant seat securely, make
sure the belt is in the lock mode before
letting the belt retract.
