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.

tion key is turned to the “ON” position.
It goes off after about 6 seconds. This
means the SRS airbags are operating
properly.
This warning light system monitors the

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.
For more detailed information concerning about the passenger risk group, please
contact NHTSA at 1 −800− 424−9393 or Transport Canada at 1 −800− 333−0371.

The SRS airbag system mainly consists of
the following components, and their loca-
tions are shown in the illustration.
1. Front airbag sensors
2. SRS warning light
3. Airbag module for right front passenger (airbag and inflator)
4. Passenger airbag manual on −off switch
5. Airbag sensor assembly
6. Airbag module for driver (airbag and inflator)
The airbag sensor assembly consists of a
safing sensor and airbag sensor. The airbag sensors constantly monitor the
forward deceleration of the vehicle. If an
impact results in a forward deceleration
beyond the designed threshold level, the
system triggers the airbag inflators. At this
time a chemical reaction in the inflators
very quickly fills the airbags with non
−tox-
ic gas to help restrain the forward motion
of the occupants. The airbags then quickly
deflate, so that there is no obstruction 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 physically and
safely exit the vehicle after a collision,
you should do so at the first opportunity. Deployment of the airbags happens in a
fraction of a second, so the airbags must
inflate with considerable force. While the
system is designed to r
educe 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 are 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.

The gauge indicates the approximate
quantity of the fuel remaining in the
tank when the ignition switch is on.
Nearly full—Needle at “F”
Nearly empty—Needle at “E”
It is a good idea to keep the tank over
1/4 full.
This fuel gauge has a non −return type
needle which remains at the last indicated
position when the ignition switch is turned
off.
If the fuel level approaches “E” or the low
fuel level warning light comes on, fill the
fuel tank as soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the fuel gauge
needle may fluctuate or the low fuel level
warning light may come on earlier than
usual.
If the fuel tank is completely empty, the
malfunction indicator lamp comes on. Fill
the fuel tank immediately.
The indicator lamp goes off after driving
several times. If the indicator lamp does
not go off, contact your Toyota dealer as
soon as possible.
