recognize him/her as a child depending on his/her physique and posture.

as an adult depending on his/her physique or posture.
∗ 4: 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 115 in this Section as for install ing 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 passenger airbag on
off indicator light indicates “ON”
when using the seat belt extender
for the front passenger seat. If the
indicator light indicates “OFF”, dis-
connect the extender tongue from
the seat belt buckle, then reconnect
the seat belt. Reconnect the seat
belt extender after making sure the
indicator light indicates “ON”. If
you use the seat belt extender
while the indicator light indicates
“OFF”, the front passenger airbag
and side airbag on the front pas-
senger side may not activate cor-
rectly, which could cause death or
serious injury in the event of colli-
sion.
Do not recline the front passenger
seatback so far that it touches a
rear 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 seat re-
turn the seatback to a position
where it does not touches the rear
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 passenger airbag on
off indicator light should indicate
“ON”. If the “OFF” indicator is illu-
minated, 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”
indicator still remains illuminated,
either ask the passenger to move to
the rear seat, or if that is not pos-
sible, 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 in the buckle before some-
one sits in the right front passen-
ger seat.
Do not place a heavy load on the
front passenger seat or the seat-
back table, etc.
Do not apply pressure to the front
passenger seat by resting hands or
legs on the seatback.
Do not let a rear 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.
Do not attach a commercial seat-
back table or other heavy item to
the back of the right front passen-
ger seat.
Child restraint systems installed on
the rear seat should not contact the
front seatbacks.

Install the child restraint system on the
front passenger seat only when it is un-
avoidable. Your vehicle is equipped with a
front passenger occupant classification
system. In order to activate the occupant
classification system correctly, install the
forward−facing child restraint system on
the front passenger seat in the following
order:
1. Turn the engine switch to the “ON” position.
2. Move the right front passenger seat to the rearward position.
3. When it is unavoidable, put the child restraint system on the front passenger
seat without putting your weight on the
front passenger seat.
4. Insert the seat belt tab into the seat belt buckle.
5. Fully extend the shoulder belt to put it in the lock mode. When the belt is
then retracted even slightly, it cannot
be extended. To hold the seat securely,
make sure the belt is in the lock mode
before letting the belt retract. 6. While pressing the convertible seat
firmly against the seat cushion and
seatback, let the shoulder belt retract
as far as it will go to hold the convert-
ible seat securely.
CAUTION
Push and pull the child restraint sys-
tem in different directions to be sure
it is secure. Follow all the installation
instructions provided by its manufac-
turer.
7. Put a child on the child restraint sys-tem and secure the child, complying
with the instructions provided by the
child restraint system manufacturer.
The passenger airbag on −off indicator light
should indicate “OFF” when the engine
switch is in the “ON” position and the
child is in the child restraint system after
following these procedures. The “OFF” in-
dicator indicates the SRS front passenger
airbag and side airbag on the passenger
side will not deploy. if the indicator light
indicates “ON”, do the following procedure: 1. Turn the engine switch off.
2. Remove the child restraint system.
3. When reinstalling a child restraint sys-
tem, make sure the seatback does not
press the child restraint system into
the seat cushion. If this occurs, adjust
the seatback angle slightly.
4. Then make sure the head restraint is not pressing the child restraint system
into the seat cushion. If this occurs,
raise the head restraint.
5. Turn the engine switch on again.
The passenger airbag on −off indicator light
should indicate “OFF”. If the indicator light
still indicates “ON” when the engine switch
is turned to the “ON” position, then the
SRS front passenger airbag and side air-
bag on the passenger side may deploy in
an accident. Do not drive the vehicle in
this condition. Remove the child restraint
system and contact your Toyota dealer.
