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.

hicle and an accident may occur re-
sulting in death or serious injuries.
