Be careful not to damage the belt
webbing or hardware. Take care that
they do not get caught or pinched
in the seat or doors.
Inspect the belt system periodically.
Check for cuts, fraying, and loose
parts. Damaged parts should be re-
placed. Do not disassemble or
modify the system.
Keep the belts clean and dry. If
they need cleaning, use a mild soap
solution or lukewarm water. Never
use bleach, dye, or abrasive clean-
ers, or allow them to come into
contact with the belt—they may se-
verely weaken the belts. (See
“Cleaning the interior” on page 447
in Section 5.)
Replace the belt assembly (includ-
ing bolts) if it has been used in a
severe impact. The entire assembly
should be replaced even if damage
is not obvious.
Ta bBuckle
Adjust the seat as needed and sit up
straight and well back in the seat. To
fasten your belt, pull it out of the re-
tractor and insert the tab into the
buckle.
You will hear a click when the tab locks
into the buckle.
The seat belt length automatically adjusts
to your size and the seat position.
The retractor will lock the belt during a
sudden stop or on impact. It also may
lock if you lean forward too quickly. A
slow, easy motion will allow the belt to
extend, and you can move around freely. When a passenger ’s shoulder belt is com-
pletely extended and is then retracted
even slightly, the belt is locked in that
position and cannot be extended. This fea-
ture is used to hold the child restraint
system securely. (For details, see “Child
restraint” on page 127 in this Section.) To
free the belt again, fully retract the belt
and then pull the belt out once more.
If the seat belt cannot be pulled out of the
retractor, firmly pull the belt and release
it. You will then be able to smoothly pull
the belt out of the retractor.CAUTION
After inserting the tab, make sure
the tab and buckle are locked and
that the belt is not twisted.
Do not insert coins, clips, etc. in
the buckle as this may prevent you
from properly latching the tab and
buckle.
If the seat belt does not function
normally, immediately contact your
Toyota dealer. Do not use the seat
until the seat belt is fixed, because
it cannot protect an adult occupant
or your child from injury.

Seat belts with an adjustable shoulder
anchor—
Adjust the shoulder anchor position to
your size.
To raise: Slide the anchor up.
To lower: Push in the lock release button
and slide the anchor down.
After adjustment make sure the anchor is
locked in position.
CAUTION
Always make sure the shoulder belt
is positioned across the center of
your shoulder. The belt should be
kept away from your neck, but not
falling off your shoulder. Failure to
do so could reduce the amount of
protection in an accident and cause
serious injuries in a collision.
To release the belt, press the buckle
release button and allow the belt to
retract.
If the belt does not retract smoothly, pull
it out and check for kinks or twists. Then
make sure it remains untwisted as it re-
tracts.

To connect the extender to the seat
belt, insert the tab into the seat belt
buckle so that the “PRESS” signs on
the buckle release buttons of the ex-
tender and the seat belt are both facing
outward as shown.
You will hear a click when the tab locks
into the buckle.
When releasing the seat belt, press on
the buckle release button on the extender,
not on the seat belt. This helps prevent
damage to the vehicle interior and extend-
er itself.As far as the seat belt extender on the
front passenger side is concerned, do not
fail to disconnect the extender from the
seat belt after the above operation in or-
der to activate the front passenger airbag
correctly when getting into the vehicle
next time.
When not in use, remove the extender
and store in the vehicle for future use.
CAUTION
After inserting the tab, make sure
the tab and buckle are locked and
that the lap and shoulder portions
of the belt and the seat belt extend-
er are not twisted.
Do not insert coins, clips, etc. in
the buckle as this may prevent you
from properly latching the tab and
buckle.
If the seat belt does not function
normally, immediately contact your
Toyota dealer. Do not use the seat
until the seat belt is fixed, because
it cannot protect an adult occupant
or your child from injury.
The driver and front passenger seat
belt pretensioners are designed to be
activated in response to a severe fron-
tal impact.
When the sensor detects a severe frontal
impact, the front seat belts are quickly
drawn back by the retractors so that the
belts snugly restrain the occupants.

The front passenger ’s seat belt pretension-
er will not activate if no passenger is
detected in the front passenger seat by
the front passenger occupant classification
system. However, the front passenger ’s
seat belt pretensioner may activate if lug-
gage is put on the seat, or the seat belt
is buckled up regardless of the presence
of an occupant in the seat. (As for the
front passenger occupant classification
system, see “—Front pass enger occupant
classification system” on page 123 in this
Section.)
The seat belt pretensioners and SRS air-
bags may not operate together in all colli-
sions.
The seat belt pretensioner system con-
sists mainly of the following components
and their locations are shown in the il-
lustration.
1. Front airbag sensors
2. SRS warning light
3. Front passenger occupant classification system (ECU and sensors)
4. Seat belt pretensioner assemblies
5. Front passenger ’s seat belt buckle switch
6. Airbag sensor assembly The seat belt pretensioners are controlled
by the airbag sensor assembly. The airbag
sensor assembly consists of a safing sen-
sor and airbag sensor.
When the seat belt pretensioners are acti-
vated, an operating noise may be heard
and a small amount of non
−toxic gas may
be released. This does not indicate that
a fire is occurring. This gas is normally
harmless.
Once the seat belt pretensioners have
been activated, the seat belt retractors
remain locked.CAUTION
Do not modify, remove, strike or open
the seat belt pretensioner assemblies,
airbag sensor or surrounding area or
wiring. Failure to follow these instruc-
tions may prevent the seat belt pre-
tensioners from activating correctly,
cause sudden operation of the system
or disable the system, which could
result in death or serious injury. Con-
sult your Toyota dealer about any re-
pair and modification.

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 second right
seat.
Same angle
When installing a child restraint
system in the third seat center
position, adjust both seatbacks to
the same angle. Otherwise, the
child restraint system cannot be se-
curely restrained and this may
cause death or serious injuries in a
collision.1. Run the lap and shoulder belt throughor 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.

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 ignition key to the “ON” posi- tion.
2. Move the front passenger seat to the rearward position.
3. 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 “AIRBAG OFF” indicator light should
be illuminated when the ignition key is
“ON” and the child is in the child restraint
system after following these proc
edures.
The “AIRBAG OFF” indicator light indi-
cates the SRS front passenger airbag and
side airbag on the passenger side will not
deploy. If the “AIRBAG ON” indicator light
is illuminated, remove the child restraint
system and reinstall it with the ignition
key in the “ACC” or “LOCK” position. If
the “AIRBAG ON” indicator light is illumi-
nated when the ignition key is turned to
the “ON” position, then the SRS front pas-
senger airbag and side airbag on the pas-
senger side may deploy in an accident.
Do not drive the vehicle in this condition.
Remove the child restraint system and
contact your Toyota dealer.
