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)
4. Separate seat only—Front passenger occupant classification system (ECU
and sensors)
5. Front passenger ’s seat belt buckle switch
6. Driver ’s seat belt buckle switch

8. For separate seat with automatic trans-
mission—Passenger airbag manual on −

10. Airbag sensor assembly
11. Airbag module for driver (airbag and inflator)
12. SRS warning light The airbag sensor assembly consists of a
safing sensor and airbag sensor.
The front airbag sensors constantly moni-
tor the forward deceleration of the vehicle.
If an impact results in a forward decelera-
tion beyond the designed threshold level,
the system triggers the airbag inflators. At
this time a chemical reaction in the infla-
tors very quickly fills the air bags with
non− toxic gas to help restrain the forward
motion of the occupants. The airbags then
quickly deflate, so that there is no ob-
struction of the driver ’s vision should it be
necessary to continue driving. When the airbags inflate, they produce a
loud noise and release some smoke and
residue along with non
−toxic gas. This
does not indicate a fire. This smoke may
remain inside the vehicle for some time,
and may cause some minor irritation to
the eyes, skin or breathing. Be sure to
wash off any residue as soon as possible
to prevent any potential skin irritation with
soap and water. If you can safely exit
from the vehicle, you should do so imme-
diately. Deployment of the airbags happens in a
fraction of a second, so the airbags must
inflate with considerable force. While the
system is desi
gned to reduce serious inju-
ries, primarily to the head and chest, it
may also cause other, less severe injuries
to the face, chest, arms and hands. These
are usually in the nature of minor burns
or abrasions and swelling, but the force of
a deploying airbag can cause more seri-
ous injuries, especially if an occupant’s
hands, arms, chest or head is in close
proximity to the airbag module at the time
of deployment. This is why it is important
for the occupant to: avoid placing any
object or part of the body between the
occupant and the airbag module; sit
straight and well back into the seat; wear
the available seat belt properly; and sit as
far as possible from the airbag module,
while still maintaining control of the ve-
hicle.
Parts of the airbag module (steering wheel
hub, airbag cover and inflator) may be hot
for several minutes after deployment, so
do not touch! The airbags inflate only
once. The windshield may be damaged by
absorbing some of the force of the inflat-
ing airbag.

CAUTION
The driver or front passenger who is
too close to the steering wheel or
dashboard during airbag deployment
can be killed or seriously injured.
Toyota strongly recommends that:
The driver sit as far back as pos-
sible from the steering wheel while
still maintaining control of the ve-
hicle.
The front passenger sit as far back
as possible from the dashboard.
All vehicle occupants be properly
restrained using the available seat
belts.
For instructions and precautions con-
cerning the seating position, see
“—Front seat precautions” in this
Section.
CAUTION
A member of a passenger risk group
should never sit or be occupied in
the front outside passenger seat with
airbag manual on −off switch in the
“ON” or “AUTO” position. (For de-
tails, see “SRS driver airbag and
front passenger airbag” in this Sec-
tion.)
Do not sit on the edge of the seat
or lean against the dashboard when
the vehicle is in use, since the
front passenger airbag could inflate
with considerable speed and force.
Anyone who is up against, or very
close to, an airbag when it inflates,
can be killed or seriously injured.
Sit up straight and well back in the
seat, and always use your seat belt
properly.

Toyota strongly recommends that all
infants and children be placed in
the rear seat of the vehicle and be
properly restrained.
Vehicles with bench seat—Do not
allow a child to stand up or kneel
on the front passenger seat, since
the front passenger airbag could in-
flate with considerable speed and
force. Otherwise, the child may be
killed or seriously injured.
Do not hold a child on your lap or
in your arms. Use a child restraint
system in the rear seat. For instruc-
tions concerning the installation of
a child restraint system, see “Child
restraint” in this Section.
Do not put anything or any part of
your body on or in front of the
dashboard or steering wheel pad
that houses the airbag system. They
might restrict inflation or cause
death or serious injury as they are
projected rearward by the force of
the deploying airbags. Likewise, the
driver and front passenger should
not hold objects in their arms or on
their knees.
