Scrapping of your Toyota
The SRS airbag and seat belt pretensioner devices in your
Toyota contain explosive chemicals. If the vehicle is
scrapped with the airbags and pretensioners left as they
are, this may  cause an accident  such as  fire. Be  sure to
have the systems of the SRS airbag and seat belt preten-
sioner removed and disposed of by a qualified service
shop or by  your Toyota dealer before you dispose of your
vehicle.
On pavement and off road
driving tips
This vehicle will handle and maneuver differently from an
ordinary passenger car because it is designed for off −road
use also. It has a significantly higher rollover rate than
other types of vehicles. In addition, this vehicle has a
higher ground clearance and center of gravity than that of
an ordinary passenger car. This vehicle design feature
causes this type of vehicle to be more likely to rollover.
Failure to operate this vehicle correctly may result in loss
of control, accidents or vehicle rollover causing death or
serious injury. Be sure to read “Off −road vehicle precau-
tions” in Section 2 and “Off −road driving precautions” in
Section 3.

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.

CAUTION
The driver or front passengers who
are 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 passengers sit as far
back as possible from the dash-
board.
All vehicle occupants be properly
restrained using the available seat
belts.
Indicator light
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” position makes the
passenger airbag system operational.
Turning the passenger airbag manual
on off switch counterclockwise to the
“OFF” position disables the passenger
airbag system. The indicator light on
the passenger airbag manual on off
switch will come on when the passen-
ger airbag system has been disabled.
See “Passenger airbag manual on −off
switch” in this section for detail.
CAUTION
Make sure that the indicator light is
off.
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 serious personal
injuries.

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 SRS airbags are operating
properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, inflators, warning light, interconnect-
ing wiring and power sources.  (For details,
see “Service reminder indicators and
warning buzzers” in Section 1− 5.)
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

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.
