If a child must sit in the front seat, the
seat belts should be worn properly. If an
accident occurs and the seat belts are not
worn properly, the force of the rapid infla-
tion of the airbag may cause death or
serious injury to the child.
Do not allow any children to stand up or
kneel on either rear or front seats. An
unrestrained child could suffer serious in-
jury or death during emergency braking or
a collision. Also, do not let the child sit
on your lap. Holding a child in your arms
does not provide sufficient restraint.
Pregnant woman. Toyota recommends the
use of a seat belt. Ask your doctor for
specific recommendations. The lap belt
should be worn securely and as low as
possible over the hips and not on the
waist.
Injured person. Toyota recommends the
use of a seat belt. Depending on the inju-
ry, first check with your doctor for specific
recommendationsCAUTION
Persons should ride in their seats
properly wearing their seat belts
whenever the vehicle is moving.
Otherwise, they are much more likely
to suffer serious bodily injury or
death in the event of sudden braking
or a collision.
When using the seat belts, observe
the following:
Use the belt for only one person at
a time. Do not use a single belt for
two or more people—even children.
Avoid reclining the seatback any
more than needed. The seat belts
provide maximum protection in a
frontal or rear collision when the
driver and the front passenger are
sitting up straight and well back in
the seats. If you are reclined, the
lap belt may slide past your hips
and apply restraint forces directly
to the abdomen or your neck may
contact the shoulder belt. In the
event of a frontal co llision, the
more the seat is reclined, the great-
er the risk of death or serious inju-
ry.
Be careful not to damage the belt
webbing or hardware. Take care that
they do not get caught or pinched
in the seat or side 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 belts—they may
severely weaken the belts. (See
“Cleaning the interior” on page 529
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.

USING FRONT SEAT BELT HANGERS
(Regular cab models)
Raise the front seat belt hanger until it
locks before you fasten the front seat
belt.
You will hear a click when the seat belt
hanger locks in raised position.
CAUTION
Make sure the seat belt hanger is
secured in the raised position before
you fasten the seat belt. If it is not,
the seat belt may not work properly.
XS13125Ta b
Buckle
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 115 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 death or serious
injury.

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 use the seat belt extender
if it is not absolutely necessary.
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 ex-
tender 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.
XS13128
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.

The seat belt pretensioners will not oper-
ate in a vehicle rollover if the “RSCA
OFF” indicator light is on. For details, see
“—Roll sensing of curtain shield airbags
off switch” on page 114 in this Section.
XS13139
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. Passenger airbag on −off indicator light
3. Front passenger occupant classification ECU
4. Load sensor
5. Seat belt pretensioner assemblies
6. Front passenger ’s seat belt buckle switch
7. Airbag sensor assembly 8. SRS warning light
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 as-
semblies, airbag sensor or sur-
rounding area or wiring. Failure to
follow these instructions may pre-
vent the seat belt pretensioners
from activating correctly, cause sud-
den operation of the system or dis-
able the system, which could result
in death or serious injury. Consult
your Toyota dealer about any repair
and modification.
