2007 TOYOTA SEQUOIA sensor

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 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
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 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

The system sounds alarm and flashes
lights when forcible entry is detected.
The alarm is triggered if any of the
side doors, back door or hood is forci-
bly unlocked or opened or the battery
terminal is disconnected and then re-
connected when the vehicle is locked.
On some models, the alarm also
sounds, when someone attempts to
break the side windows.

WHEN THE SYSTEM IS SET
Activating the system
The system will sound the alarm under
the following conditions:
If any of the side doors is unlocked or
opened without the key or wireless re-
mote control transmitter, or if the back
door or hood is forcibly opened
If the battery terminal is disconnected
and then reconnected
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.
If the alarm has been activated and the
key is not in the ignition switch, all the
side doors and back door will re −lock au-
tomatically.
After one minute, the alarm will automati-
cally stop and the indicator light will starts
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
two ways:
Turn the ignition key from the “LOCK”
to “ON” position.
Unlock any of the side doors or back
door with the key or wireless remote
control transmitter.
These ways cancel the system at the
same time. TESTING THE SYSTEM
1. Open all the windows.
2. Set the system as described above. The side doors and back door should
be locked with the key or wireless re-
mote control transmitter. Be sure to
wait until the indicator light goes off or
starts flashing.
3. Unlock any side door from the inside. The system should activate the alarm.
4. Stop the alarm as described above.
5. Repeat this operation for the other doors and hood. When testing the
hood, also check that the system is
activated when the battery terminal is
disconnected and then reconnected.
If the system does not work properly,
have it checked by your Toyota dealer.

The driver and front passenger seat
belt pretensioners are designed to be
activated in response to a severe fron-
tal impact. The pretensioners are also
activated during vehicle rollover.
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 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 103 in this
Section.)
The seat belt pretensioners and SRS air-
bags may not operate together in all colli-
sions.
u13228
The seat belt pretensioners will not oper-
ate in a vehicle rollover if the “RSCA
OFF” indicator light is on. For details, see
“Roll sensing of curtain shield airbags off
switch” on page 107 in this Section.

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
front 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 retractor 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

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, side and curtain shield airbag sen-
sors, curtain shield airbag sensors, driv-
er ’s seat position sensor, driver ’s seat belt
buckle switch, front passenger occupant
classification system and indicator light,

ors, “RSCA OFF” indicator light, intercon-
necting wiring and power sources. (For
details, see “Service reminder indicators
and warning buzzers” on page 164 in Sec-
tion 1
−6.)
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.

ignition key is turned to the “ON” posi-
tion or remains on for more than 6
seconds.
The light comes on or starts flashing

u13241
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
