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 serious 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
deployment. This is just one example of how the instruc-
tions in Section 1−3 of this Owner ’s Manual will help en-
sure proper use of the occupant restraint systems, and
increase the safety they can provide to you and your fami-
ly in the event of an accident.
Toyota recommends you to read the provisions in Section
1 −3 carefully and refer to them as needed during your time
of ownership of this vehicle.Event data recorder
Your vehicle has computers that monitor and control cer-
tain aspects of your vehicle. These computers assist in
driving and maintaining optimal vehicle performance. Be-
sides storing data useful for troubleshooting, there is a
system to record data in a crash or a near car crash
event. This is called an Event Data Recorder (EDR).
The SRS airbag sensor assembly contains the EDR. In a
crash or a near car crash event, this device may record
some or all of the following information:
 Engine speed
 Whether the brake pedal was applied or not
 Vehicle speed
 To what extent the accelerator pedal was depressed
 Position of the transmission selector lever
 Whether the driver and front passenger wore the seat
belts or not
 Driver’s seat position
 Front passenger ’s occupant classification

To connect the extender to the seat
belt, insert the tab into the seat belt
buckle so that the “PRESS” signs on
the buckle release buttons of the ex-
tender and the seat belt are both facing
outward as shown.
You will hear a click when the tab locks
into the buckle.
When releasing the seat belt, press on
the buckle release button on the extender,
not on the seat belt. This helps prevent
damage to the vehicle interior and extend-
er itself. As far as the seat belt extender on the
front passenger side is concerned, do not
fail to disconnect the extender from the
seat belt after the above operation in or-
der 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. On vehicles equipped with
curtain shield airbags, the pretensioners
are also activated during vehicle rol-
lover.
When the sensor detects a severe frontal
impact or a vehicle rollover, the front seat
belts are quickly drawn back by the re-
tractors so that the belts snugly restrain
the occupants.

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. Front passenger occupant classification indicator light
3. 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.
NOTICE
Do not perform any of the following
changes without consulting your
Toyota dealer. Such changes can
interfere with proper operation of the
seat belt pretensioners in some
cases.
 Installation of electronic devices
such as a mobile twoway radio,
cassette tape player or compact
disc player
 Repairs on or near the front seat
belt pretensioner assemblies
 Modification of the suspension sys-
tem
 Modification of the front end struc-
ture
 Attachment of a grille guard (bull
bar, kangaroo bar, etc.), snowplow,
winches or any other equipment to
the front end
 Repairs made on or near the front
fenders, front end structure or con-
sole

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 acci dent
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.
Your vehicle is equipped with “ADVANCED
AIRBAGS” designed based on US motor
vehicle safety standards (FMVSS208). The
airbag system controls airbag deployment
power for the driver and front passenger.
The driver airbag system consists of the
driver seat’s position sensor etc. The front
passenger ’s airbag system consists of the
front passenger occupant classification
sensor etc. The SRS airbags are designed to protect
the driver and right front passenger and
they are not designed to protect an occu-
pant in the front center seating position.
In response to a severe frontal impact,
the SRS airbags work with the seat belts
to help reduce injury by inflating. The SRS
airbags help reduce injuries mainly to the
driver ’s or front passenger ’s head or chest
caused by hitting the vehicle interior.
The SRS front passenger airbag will not
activate if there is no passenger sitting in
the right front passenger seat. However,
the front passenger airbag may deploy if
luggage is put in the seat, or the seat belt
is buckled up, regardless of the presence
of an occupant in the seat. (As for the
front passenger occupant classification
system, see “Front passenger occupant
classification system” in this Section.)
Always wear your seat belt properly.

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 and passenger airbag off
indicator light
3. Airbag module for right front passenger (airbag and inflator)
4. Front passenger occupant classification system (ECU and sensors)
5. Front passenger ’s seat belt buckle switch
6. Driver ’s seat belt buckle switch
7. Passenger ’s seat position sensor 8. Driver ’s seat position sensor
9. Passenger airbag off switch
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.

Do not modify or remove any wir-
ing. Do not modify, remove, strike
or open any components such as
the steering wheel pad, steering
wheel, column cover, dashboard
near the front passenger airbag,
front passenger airbag cover, front
passenger airbag or airbag sensor
assembly. Doing so may prevent the
front airbag system from activating
correctly, cause sudden activation
of the system or disable the sys-
tem, which could result in death or
serious injury.
Do not use seat accessory, such as
a cushion or seat cover, that covers
the front seat, or do not modify or
