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.
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” in this section.) To free the belt
again, fully retract the belt and then pull
the belt out once more.
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. It cannot
protect an adult occupant or your
child from injury.

protection in an accident and cause
severe injuries in a co llision.

To release the belt, press the bucklere-
lease button.The rear seat belt and buckles can be
stowed when not in use.
Seat belt and buckles must be stowed
before you swing up the bottom cushion.
(See “Swing−up rear seats” in this sec-
tion.) 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 so
that the dealer can order the proper re-
quired length for the extender. Bring the
heaviest coat you expect to wear for prop-
er measurement and selection of length.
Additional ordering information is available
at your Toyota dealer.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
vehicle accident, increasing the
chance of personal injury.
Never use the seat belt extender if
you can fasten the seat belt without
it.

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.
To connect the extender to the seat
belt, insert the tab into the seat belt
buckle so that the “PRESS” signs on
the bucklerelease 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.
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 seat belt extender 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. It cannot
protect an adult occupant or your
child from injury.

The driver and front passenger ’s seat
belt pretensioners are designed to be
activated in response to a severe fron-
tal impact.
When the airbag sensor detects the shock
of a severe frontal impact, the front seat
belts are quickly drawn back in by the
retractors so that the belts snugly restrain
the front seat occupants.
The front seat belt pretensioners are acti-
vated even with no passenger in the front
seat.
Collisions occurring at certain s peeds and
angles may cause the seat belt preten-
sioners and SRS airbags not to operate
all together.This indicator comes on when the igni-
tion key is turned to the “ON” position.
It goes off after about 6 seconds. This
means the front seat belt pretensioners
are operating properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, seat belt pretensioner assemblies,
inflators, warning light, interconnecting wir-
ing and power sources. (For details, see
“Service reminder indicators and warning
buzzers” in Section 1 −5.)The front seat belt pretensioner system
mainly consists of the following compo-
nents and their locations are shown in the
illustration.
1. Front airbag sensors
2. SRS warning light
3. Front seat belt pretensioner assemblies
4. Airbag sensor assembly
The front seat belt pretensioners are con-
trolled by the airbag sensor assembly. The
airbag sensor assembly consists of a saf-
ing sensor and airbag sensor.

When the front seat belt pretensioners are
activated, an operating noise may be
heard and a small amount of smoke −like
gas may be released. This gas is harm-
less and does not indicate that a fire is
occurring.
Once the front seat belt pretensioners
have been activated, the seat belt retrac-
tors remain locked.
CAUTION
Do not modify, remove, strike or open
the front seat belt pretensioner as-
semblies, airbag sensor or surround-
ing area or wiring. Doing so may
cause sudden operation of the front
seat belt pretensioners or disable the
system, which could result in death
or serious injury.
Failure to follow these instructions
can result in death or serious inju-
ries. Consult your Toyota dealer
about any repairs and modifications.
NOTICE
Do not perform any of the following
changes without consulting your
Toyota dealer. Such changes can
interfere with proper operation of the
front seat belt pretensioners in some
cases.
 Installation of electronic devices
such as a mobile twoway radio,
cassette tape player or compact
disc player
 Repairs on or near the front seat
belt pretensioner assemblies
 Modification of the suspension sys-
tem
 Modification of the front end struc-
ture
 Attachment of a grille guard (bull
bar, kangaroo bar, etc.), snowplow,
winches or any other equipment to
the front end
 Repairs made on or near the front
fenders, front end structure or con-
sole
This front seat belt pretensioner system
has a service reminder indicator to inform
the driver of operating problems. If any of
the following conditions occurs, this
indicates a malfunction of the airbags or
pretensioners. Contact your Toyota dealer
as soon as possible to service the
vehicle.
The light does not come on when the
ignition key is turned to the “ON” posi-
tion, or the light remains on.
The light comes on or flashes while
driving.
If either front seat belt does not retract
or cannot be pulled out due to a mal-
function or activation of the relevant
front seat belt pretensioner.

In the following cases, contact your Toyota
dealer as soon as possible:
The front of the vehicle (shaded in the
illustration) was involved in an acci dent
that was not severe enough to cause
the front seat belt pretensioners to op-
erate.
Either front seat belt pretensioner as-
sembly or surrounding area is
scratched, cracked, or otherwise dam-
aged.
The SRS (Supplemental Restraint Sys-
tem) airbags are designed to provide
further protection for the driver and
right front passenger in addition to the
primary safety protection provided by
the seat belts.
Vehicles with separate front seats—The
SRS airbags are designed to protect
the driver and front passenger.
Vehicles with bench type front seats—
The SRS airbags are designed to pro-
tect the driver and right −front passen-
ger. They are not designed to protect
occupant in the center position. In response to a severe frontal impact,
the SRS airbags work together with the
seat belts to help reduce injury by inflat-
ing. The SRS airbags help to reduce inju-
ries mainly to the driver’s or right front
passenger ’s head or chest caused by di-
rectly hitting the steering wheel or dash-
board. The front passenger airbag is acti-
vated even with no passenger in the front
seat.
Be sure to wear your seat belt properly.
Your vehicle is equipped with a crash
sensing and diagnostic module, which will
record the use of the seat belt restraint
system by the driver and right front pas-
senger when the SRS airbags are inflated.
