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.

If any seat belt does not retract or can
not be pulled out due to a malfunction
or activation of the relevant seat belt
pretensioner.
The seat belt pretensioner assembly or
surrounding area has been damaged.
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 accident
that was not severe enough to cause
the seat belt pretensioners to operate.
Either seat belt pretensioner assembly
or surrounding area is scratched,
cracked, or otherwise damaged.
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 bench seat—The SRS air-
bags are designed to protect the driver
and right front passenger and they are not
designed to protect an occupant in the
front center seating 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 reduce injuries
mainly to the driver ’s or front passenger ’s
head or chest caused by hitting the ve-
hicle interior.
Vehicles with bench seat—The SRS front
passenger airbag is activated even with
no passenger in the front seat.
Vehicles with separate seat—The SRS
front passenger airbag will not activate if
there is no passenger sitting in the front
passenger seat. However, the front pas-
senger airbag may deploy if luggage is
put in the seat, or the seat belt is buckled
up, regardless of the presence of an oc-
cupant in the seat. (As for the front pas-
senger occupant classification system, see
“Front passenger occupant classification
system” in this Section.)
Always wear your seat belt properly.CAUTION
The SRS airbag system is designed
only as a supplement to the prima-
ry protection of the driver and front
passenger seat belt systems. The
driver and front passenger can be
killed or seriously injured by the
inflating airbags if they do not wear
the available seat belts properly.
During sudden braking just before
a collision, an unrestrained driver
or front passenger can move for-
ward into direct contact with or
close proximity to the airbag which
may then deploy during the colli-
sion. To ensure maximum protection
in an accident, the driver and all
passengers in the vehicle must
wear their seat belts properly. Wear-
ing a seat belt properly during an
accident reduces the chances of
death or serious injury or being
thrown out of the vehicle. For in-
structions and precautions concern-
ing the seat belt system, see “Seat
belts” in this Section.
Improperly seated and/or restrained
infants and children can be killed
or seriously injured by the deploy-
ing airbags. An infant or child who
is too small to use a seat belt
should be properly secured using a
child restraint system. Toyota
strongly recommends that all in-
fants and children be placed in the
rear seat of the vehicle and proper-
ly restrained. The rear seat is the
safest for infants and children. For
instructions concerning the installa-
tion of a child restraint system, see
“Child restraint” in this Section.

The passenger airbag system is
equipped with a manual on −off switch
and indicator light. Turning the passen-
ger airbag manual on −off switch clock-
wise to the “ON” or “AUTO” position
makes the passenger airbag system op-
erational. To disable the passenger air-
bag system, turn the manual on −off
switch counterclockwise to the “OFF”
position and remove the key. The indi-
cator light on the passenger airbag
manual on− off switch will come on
when the passenger airbag system has
been disabled.
See “Passenger airbag manual on −off
switch” in this Section for detail.
CAUTION
Do not turn off the passenger air-
bag manual on− off switch except
when a member of a passenger risk
group identified in TABLE 1 is oc-
cupying the right front passenger
seating position.
When the passenger airbag manual
on− off switch is turned off, the pas-
senger airbag will not inflate in a
collision and turning off the pas-
senger airbag can reduce the occu-
pant protection which your vehicle
safety systems can provide to you
in certain accidents and increase
the likelihood of death or serious
personal injuries.

The SRS airbags are designed to deploy
in severe (usually frontal) co llisions
where the magnitude and duration of
the forward deceleration of the vehicle
exceeds the designed threshold level.
The SRS airbags will deploy if the severi-
ty of the impact is above the designed
threshold level, comparable to an approxi-
mate 25 km/h (15 mph) collision when the
vehicle has the impact straight into a fixed
barrier that does not move or deform.
However, this threshold velocity will be
considerably higher if the vehicle strikes
an object, such as a parked vehicle or
sign pole, which can move or deform on
impact, or if the vehicle is involved in an
underride collision (e.g. a collision in
which the front of the vehicle “underrides”,
or goes under, the bed of a truck, etc.).
It is possible that in some collisions
where the forward deceleration of the ve-
hicle is very close to the designed thresh-
old level, the SRS airbags and front seat
belt pretensioners may not activate togeth-
er.
Always wear your seat belts properly.TABLE 1: A PASSENGER RISK GROUP
Infant. An infant (less than 1 year old) who must ride in the front seat because:
Vehicle has no rear seat;
Vehicle has a rear seat too small to accommodate a rear −facing infant seat;
or
The infant has a medical condition which, according to the infant’s physician,
makes it necessary for the infant to ride in the front seat so that the driver
can constantly monitor the child’s condition.
Child age 1 to 12. A child age 1 to 12 must ride in the front seat because:
Vehicle has no rear seat:
Although children ages 1 to 12 ride in the rear seat(s) whenever possible,
children ages 1 to 12 sometimes must ride in the front because no space is
available in the rear seat(s) of vehicle; or
The child has a medical condition which, according to the child’s physician,
makes it necessary for the child to ride in the front seat so that the driver can
constantly monitor the child’s condition.
Medical condition. A passenger has a medical condition which according to his
or her physician:
Causes the passenger airbag to pose a special risk for the passenger: and
Makes the potential harm from the passenger airbag in a crash greater than the
potential harm from turning off the airbag and allowing the passenger, even if
belted, to hit the dashboard, or windshield in a crash.

Collision from the rear
Collision from the side Vehicle rollover
The SRS airbags are generally not de-
signed to inflate if the vehicle is in-
volved in a side or rear collision, if it
rolls over, or if it is involved in a low −
speed frontal collision. But, whenever a
collision of any type causes sufficient
forward deceleration of the vehicle, de-
ployment of the SRS airbags may oc-
cur.
Hitting a curb,
edge of pavement
or hard surface Falling into or
jumping over a
deep hole
Landing hard or vehicle falling
The SRS airbags may also deploy if a
serious impact occurs to the underside
of your vehicle. Some examples are
shown in the illustration.The SRS airbag system consists mainly of
the following components, and their loca-
tions are shown in the illustration. 1. Front airbag sensors
2. Front passenger occupant classification indicator light or passenger airbag on −
off indicator light
3. Airbag module for right front passenger (airbag and inflator)
