■When a small adult is seated in
the front passenger’s seat
When a small adult is seated in the front passenger’s seat, the SRS fron-
tal airbag system may or may not acti-
vate the front passenger’s SRS frontal airbag depending on the occu-
pant’s seating posture. If the OFF
indicator remains illuminated while
the ON indicator turns off when a small adult is seated in the front pas-
senger's seat, refer to P.46.
■General Precautions regarding
occupant detection system
Do not kick the front passenger seat or subject it to severe impact. Other-
wise, the SRS warning light may illu-
minate to indicate a malfunction of the front passenger occupant detection
system. In this case, we recommend
that you contact your Toyota dealer immediately.
■After deployment
Do not touch the SRS airbag system
components with bare hands right
after deployment. Doing so can cause burns because the components can
be very hot as a result of deployment.
NOTICE
■Front passenger’s SRS frontal
airbag
Observe the following precautions.
Failure to do so may prevent the front
passenger’s SRS frontal airbag from functioning co rrectly or cause the sys-
tem to fail.
●Do not apply any strong impact to
the front passenger’s seat such as
by kicking.
●Do not let rear passengers rest their
feet between the front seatback and seat cushion.
●Do not spill liquid on the front pas-senger’s seat. If liquid is spilled,
wipe it off immediately.
●Do not remove or disassemble the
front passenger’s seat.
●Do not install any accessory (such
as an audio amplifier) other than a
genuine Toyota accessory under the front passenger’s seat.
●Do not place anything (shoes, umbrella, etc.) under the front pas-
senger’s seat.
●Do not place any objects (books,
etc.) around the front passenger’s
seat.
●Do not use the front passenger’s
seat with the head restraint removed.
●Do not leave any articles on the front passenger’s seat or the
seatbelt tongue and buckle
engaged when you leave your vehi- cle.
●Do not put sharp object(s) on the seat or pierce the seat upholstery.
●Do not place a magnet near the seatbelt buckle and the seatbelt
retractor.
●Do not use front seats with their for-
ward-backward position adjuster
and seatback adjuster not being locked into place securely. If any of
them are not locked securely, adjust
them again. For adjusting proce- dure, refer to P.117.
■When using a child restraint sys-
tem
Observe the following precautions as
it increase the load on the front pas-
senger's seat and not work properly.

The driver’s and front passenger’s
SRS side airbags and SRS curtain
shield airbags deploy inde-
pendently of each other since each
has its own impact sensor. There
fore, they may not both deploy in
the same accident. Also, the SRS
side airbag and SRS curtain shield
airbag deploy independently of the
driver’s and front passenger’s SRS
frontal airbags in the steering wheel
and instrument panel.
An impact sensor, which senses
impact force, is located in each of
the following locations.
 In the left and right center pillars
 In the left and right rear wheel
houses
 In the left and right doors
 In the airbag control module
After the deployment, the SRS side
airbag immediately starts to deflate.
The time required from detection of
an impact to deflation of an SRS
side airbag after deployment is
shorter than the blink of an eye.
The SRS curtain shield airbag
remains inflated for a while follow-
ing deployment then slowly
deflates.
The SRS side airbag and SRS cur-
tain shield airbag deploy even
when no one occupies the seat on
the side on which an impact is
applied.
The SRS side airbag and SRS cur-
tain shield airbag are designed to
deploy in the event of an accident
involving a moderate to severe side
impact collision. They are not
designed to deploy in most lesser
side impacts. Also, they are not
designed to deploy in most frontal
or most rear impacts because SRS
side airbag and SRS curtain shield
airbag deployment would not help
the occupant in those situations.
Each SRS side airbag and SRS
curtain shield airbag are designed
to function on a onetime- only
basis.
SRS side airbag and SRS curtain
shield airbag deployment depend
on the level of force experienced in
the passenger compartment during
a side impact collision. That level
differs from one type of collision to
another, and it may have no bear-

●Do not allow the rear seat occupant
to place his/her hands or legs on
the front passenger's seatback, or allow him/her to pull the seatback.

 When is the SRS curtain shield
airbag unlikely to deploy?
There are many types of collisions
which might not necessarily require
SRS curtain shield airbag deployment.
In the event of accidents like those illus-
trated, the SRS curtain shield airbag
may not deploy depending on the level
of accident forces involved.
• The vehicle is involved in an oblique
side-on impact.
• The vehicle is involved in a side-on
impact in an area outside the vicinity
of the passenger compartment.
• The vehicle strikes a telephone pole
or similar object.
• The vehicle is involved in a side-on
impact from a motorcycle.
• The vehicle rolls onto its side or the
roof.

Points to remember
WA R N I N G
■When a child is riding
Observe the following precautions.
Failure to do so may result in death or
serious injury.
●For effective protection in automo- bile accidents and sudden stops, a
child must be properly restrained,
using a seat belt or child restraint system which is corr ectly installed.
For installation details, refer to the
operation manual enclosed with the child restraint system. General
installation instruction is provided in
this manual.
●Toyota strongly urges the use of a
proper child rest raint 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 someone
else’s arms is not a substitute for a child restraint system. In an acci-
dent, the child can be crushed
against the windshield or between the holder and the interior of the
vehicle.
■Handling the child restraint sys-
tem
If the child restraint system is not properly 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 vehicle were to receive a
strong impact from an accident,
etc., it is possible that the child restraint system has damage that is
not readily visible. In such cases,
do not reuse the restraint system.

581-2. Child safety
■When installing a child
restraint system to a front pas-
senger seat
Child restraint systems cannot be
installed to the front passenger's
seat.

●Depending on the child restraint
system, installation may be difficult
or impossible. In those cases, check whether the child restraint
system is suitable for installment in
the vehicle. ( P.60) 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 opera- tion manual enclosed with the child
restraint system.
●Keep the child re straint 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
Observe the following precautions. Failure to do so may result in death or
serious injury.
●Never use a rear-facing child restraint system on the front pas-
senger seat.
The force of the rapid inflation of the front passenger airbag can
cause death or serious injury to
children in the event of an accident.
●There is a label(s) on the passen-
ger side sun visor, indicating it is forbidden to attach a rear-facing
child restraint system to the front
passenger seat. However, as child restraint systems cannot be
installed to the front passenger seat
of this model, do not use a child restraint system on the front pas-
senger seat regardless of the direc-
tion it is facing. Details of the label(s) are shown in
the illustration below.

●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 system. It is dangerous if the SRS side
airbags and curtain shield airbags
inflate, and the impact could cause death or serious injury to the child.
●When a junior 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 child restrain t system suitable to the age and size of the child and
install it to the rear seat.
