Important information about your Toyota
Occupant restraint systems
Toyota encourages you and your family to take the time to
read Section 1 −3 of this Owner’s Manual carefully. In
terms of helping you understand how you can receive the
maximum benefit of the occupant restraint systems this
vehicle provides, Section 1 −3 of this Owner ’s Manual is
the most important Section for you and your family to
read.
Section 1 −3 describes the function and operation concern-
ing seats, seat belts, SRS airbags and child restraint sys-
tems of this vehicle and some potential hazards you
should be aware of. These systems work together along
with the overall structure of this vehicle in order to provide
occupant restraint in the event of a crash. The effect of
each system is enhanced when it is used properly and
together with other systems. No single occupant restraint
system can, by itself, provide you or your family with the
equal level of restraint which these systems can provide
when used together. That is why it is important for you and
your family to understand the purpose and proper use of
each of these systems and how they relate to each other.
The purpose of all occupant restraint systems is to help
reduce the possibility of death or serious injury in the
event of a collision. None of these systems, either individ-
ually or together, can ensure that there is no injury in the
event of collision. However, the more you know about
these systems and how to use them properly, the greater
your chances become of surviving an accident without
death or serious injury.
Seat belts provide the primary restraint to all occupants of
the vehicle, and every occupant of the vehicle should wear
seat belts properly at all times. Children should always be
secured in child restraint systems that are appropriate for
their age and size. SRS (Supplemental Restraint System)
airbags are, as their names imply, designed to work with,
and be supplemental to, seat belts and are not substitutes
for them. SRS airbags can be very effective in reducing
the risk of head and chest injuries by preventing contact of
the head and chest with interior portions of the vehicle.

In order to be effective, the SRS airbags must deploy with
tremendous speed. The rapid deployment of the SRS air-
bags makes the SRS airbags themselves potential sources
of injury if an occupant is too close to an airbag, or if an
object or some part of his or her body has been placed
between the occupant and the airbag at the time of deploy-
ment. This is just one example of how the instructions in
Section 1 −3 of this Owner ’s Manual will help ensure proper
use of the occupant restraint systems, and increase the
safety they can provide to you and your family in the event
of an accident.
Toyota recommends you to read the provisions in Section
1 −3 carefully and refer to them from time to time during
your time of ownership of this vehicle.New vehicle warranty

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.
Onpavement and offroad
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.

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.
The seat belt pretensioners are activated
even with no passenger in the front seat.
The seat belt pretensioners and SRS air-
bags may not operate together in all colli-
sions.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. SRS warning light
3. Seat belt pretensioner assemblies
4. Airbag sensor assembly
The seat belt pretensioners are controlled
by the airbag sensor assembly. The airbag
sensor assembly consists of a safing sen-
sor and airbag sensor.

If any of the following conditions occurs,
this indicates a malfunction of the airbags
or seat belt pretensioners. Contact your
Toyota dealer as soon as possible.
When the ignition key is turned to the
“ON” position, the light does not come
on, remains on or flashes.
The light comes on or starts flashing
while driving.
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 type front seats—The
SRS airbags 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.
The front passenger airbag is activated
even with no passenger in the front seat.
Always 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.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 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, when ever 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. 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.
