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 s houlder. Failure to
do so could reduce the amount of
protection in an accident and cause
severe injuries in a co llision.
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.FRONT CENTER SEAT BELT (standard
cab models with non−split bench seat)
AND REAR CENTER SEAT BELT (access
cab models)
The center seat belt is a 3 −point type
restraint with 2 buckles. Both seat belt
buckles must be correctly located and se-
curely latched for proper operation.
Make sure buckle 1 (with light gray
buckle −release button) is securely latched
for ready use of the center seat belt.

Front center seat belt only—
Make sure the shoulder belt pass
through the guide when using the seat
belt for front center seat.Two buckles and tabs for center seat
belt
The 2 buckles for the center seat belt are
distinguished with colors of the buckle re-
lease button. Also the 2 tabs have differ-
ent shape for its end so that the belt is
not buckled in the wrong place.
Buckle 1 (with light gray buckle −re-
lease button)—Properly matches with
concave end tab
Buckle 2 (with red buckle −release but-
ton)—Properly matches with round end
tab
CAUTION
Make sure the both buckles are cor-
rectly located and securely latched.
Failure to properly match the buckle
and tab may cause severe injury in
case of an accident or a collision.

To release the concave end tab, insert the
key into the hole on buckle 1 (with light
gray buckle −release button) and allow the
belt to retract.CAUTION
Do not use the center seat belt with
either buckle released. Fastening only
the shoulder belt or lap belt may
cause severe personal injury in case
of sudden braking or a co llision.
The rear seat belt buckles can be
stowed when not in use.
Seat belt buckles must be stowed before
you swing up the bottom cushion. (See
“Swing−up rear seats” in this Section.)

The rear seat belt buckles can be
stowed when not in use.
Seat belt buckles must be stowed before
you fold the seatback. (See “Tumbling rear
seats” in this Section.) If your seat belts cannot be fastened se-
curely because they are not long enough,
a personalized seat belt extender is avail-
able from your Toyota dealer free of
charge.
Please contact your local Toyota dealer to
order the proper required length for the
extender. Bring the heaviest coat you ex-
pect to wear for proper measurement and
selection of length. Additional ordering in-
formation is available at your Toyota deal-
er.CAUTION
When using the seat belt extender,
observe the following precautions.
Failure to follow these instructions
could reduce the effectiveness of the
seat belt restraint system in case of
an accident, increasing the chance of
personal injury.
Remember that the extender pro-
vided for you may not be safe when
used on a different vehicle, for
another person, or at a different
seating position than the one origi-
nally intended.
If the seat belt extender has been
connected to the driver’s seat belt
buckle without wearing the seat belt
when using the extender in the
driver ’s seat, the SRS driver ’s air-
bag system will judge that the driv-
er wears the seat belt even if not
wearing it. In this case, the driver ’s
airbag may not activate correctly,
causing death or serious injury in
the event of collision. Be sure to
wear the seat belt with the seat belt
extender.

Vehicles with separate seat—Make
sure the front passenger occupant
classification indicator light indi-
cates “ON” when using the seat
belt extender for the front passen-
ger seat. If the indicator light indi-
cates “OFF”, disconnect the extend-
er tongue from the seat belt buckle,
then reconnect the seat belt. Recon-
nect the seat belt extender after
making sure the indicator light indi-
cates “ON”. If you use the seat belt
extender while the indicator light
indicates “OFF”, the front passen-
ger airbag and side airbag on the
front passenger side may not acti-
vate correctly, which could cause
death or serious injury in the event
of collision.
Be sure to wear the seat belt with-
out the seat belt extender if you
can fasten the seat belt without the
extender.
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
extender 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.
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.

Vehicles with separate seat—As far as the
seat belt extender on the front passenger
side is concerned, do not fail to discon-
nect the extender from the seat belt after
the above operation in order 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.
Vehicles with bench seat—The seat belt
pretensioners are activated even with no
passenger in the front seat. Vehicles with separate seat—The front
passenger ’s seat belt pretensioner will not
activate if no passenger is detected in the
front passenger seat by the front passen-
ger occupant classification system. How-
ever, the front passenger ’s seat belt pre-
tensioner may activate if luggage is put
on the seat, or the seat belt is buckled
up regardless of the presence of an occu-
pant in the seat. (As for the front passen-
ger occupant classification system, see
“Front passenger occupant classification
system” in this Section.)
The seat belt pretensioners and SRS air-
bags may not operate together in all colli-
sions.

Double cab models only—The seat belt
pretensioners will not operate in a vehicle
rollover if the “RSCA OFF” indicator light
is on. For details, see “Roll sensing of
curtain shield airbags off switch” in this
Section.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. Separate seat only—Front passenger occupant classification indicator light
3. Separate seat only—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
7. 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 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.
