In order to be effective, the SRS airbags must deploy with
tremendous speed. The rapid deployment of the SRS airbags
makes the SRS airbags themselves potential sources of
death or 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 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 as needed during your time
of ownership of this vehicle.Event data recorder
Your vehicle has computers that monitor and control certain
aspects of your vehicle. These computers assist in driving
and maintaining optimal vehicle performance. Besides 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

two beeps will be heard and the turn
signal lights flash twice.
The doors may not unlock if the handle
is grasped too quickly. Be sure to confirm
that the doors are unlocked before pulling
the door handle. If the doors do not open
when the handle is pulled, return the han-
dle to its original position.

To deter vehicle theft, the system is
designed to sound an alarm if any of
the doors, trunk or hood is forcibly un-
locked or the battery terminal is discon-
nected and then reconnected when the
vehicle is locked.
The alarm also sounds, when someone
attempts to break the side windows.
The alarm blows the horn intermittently
and flashes the headlights, turn signal
lights, tail lights and interior light.Indicator light

WHEN THE SYSTEM IS SET
Activating the system
The system will sound the alarm under
the following conditions:
If any of the doors is unlocked or if
the trunk or hood is forcibly opened
without the key, wireless remote control
or entry function of the smart key sys-
tem.
If the battery terminal is disconnected
and then reconnected.
If the ignition is hotwired.
Vehicles with the glass breakage sensor—
The side windows are tapped or bro-
ken.
The indicator light will come on when the
system is activated.
All the doors will be automatically locked
again when the following two conditions
are met:
If any of the doors is unlocked without
the key, wireless remote control or
entry function of the smart key system.
If the key is not in the ignition switch
(vehicles with key cylinder −type ignition
switch) or the ignition switch is set to
off (vehicles with smart key system). After one minute, the alarm will automati-
cally stop and the indicator light will start
flashing again.
Reactivating the alarm
Once set, the system automatically resets
the alarm after the alarm stops.
The alarm will activate again under the
same circumstances described in
“Activating the system”.
Stopping the alarm
The alarm will be stopped by the following
three ways:
Set the ignition switch to ON.
Unlock any of the doors with the key,
wireless remote control or entry func-
tion of the smart key system.
Open the trunk with the wireless re-
mote control or entry function of the
smart key system.
CANCELLING THE SYSTEM
The system will be cancelled by the
above mentioned 3 ways.
If the tail lights come on for 2 seconds,
the theft deterrent system has been
alarmed. Check to see if there is any
abnormality with your vehicle. TESTING THE SYSTEM
1. Open all the windows.
2. Set the system as described above. The doors should be locked with the
key, wireless remote control or entry
function of the smart key system. Be
sure to wait until the indicator light
starts flashing.

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 portion of
the belt and the seat belt extender
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 death or serious
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.
—Seat belt pretensioners

77
The front passenger ’s seat belt pretension-
er will not activate if no passenger is
detected in the front passenger seat by
the front passenger occupant classification
system. However, the front passenger ’s
seat belt pretensioner may activate if lug-
gage is put on 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 pass enger occupant
classification system” on page 94 in this
Section.)
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. “AIRBAG ON” and “AIRBAG OFF” indi- cator lights
4. Front passenger occupant classification system (ECU and sensors)
5. Seat belt pretensioner assemblies
6. Front passenger ’s seat belt buckle switch
7. 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.
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.
