sensor TOYOTA xD 2011 Owners Manual (in English)

iv
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 poten-
tial 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 family in the event of an
accident.
Scion 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 shift lever
 Whether the driver and front passenger wore the
seat belts or not
 Driver ’s seat position
 Front passenger ’s occupant classification

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
Scion 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.
—Seat belt pretensioners
Both front seats are equipped with seat
belt pretensioners and are designed to
be activated in response to a severe
frontal 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.

50
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 68.)
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. “AIR BAG ON” and “AIR BAG OFF” indicator lights
4. Front passenger occupant classification system (ECU and sensors)
5. Seat belt pretensioner assemblies
6. Front passenger ’s seat belt buckle switch
7. Driver ’s seat belt buckle switch
8. 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.
If the vehicle is involved in multiple colli-
sions, the pretensioner will activate for the
first collision, but will not activate for the
second or subsequent collisions.

51
CAUTION
Observe the following precautions to
reduce the risk of injury in the event
of sudden braking or an accident.
Failure to do so may cause death or
severe injury.
If the pretensioner has activated,
the SRS warning light will come on.
In that case, the seat belt cannot
be used again and must be re-
placed at your Scion dealer.
Do not modify, remove, strike or
open the seat belt pretensioner as-
semblies, airbag sensor or sur-
rounding area or wiring. Consult
your Scion dealer about any repair
and modification.
NOTICE
Do not perform any of the following
changes without consulting your
Scion dealer. Such changes can inter-
fere 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 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
This indicator comes on when the en-
gine switch is turned to the “ON” posi-
tion. It goes off after about 6 seconds.
This means the seat belt pretensioners
are operating properly.
This warning light system monitors the air-
bag sensor assembly, front airbag sensors,
side and curtain shield airbag sensors, cur-
tain shield airbag sensors, driver ’s seat
position sensor, driver ’s seat belt buckle
switch, front passenger occupant classifica-
tion system, “AIR BAG ON” indicator light,
“AIR BAG OFF” indicator light, front pas-
senger ’s seat belt buckle switch, seat belt
pretensioner assemblies, inflators, intercon-
necting wiring and power sources. (For de-
tails, see “Service reminder indicators and
warning buzzers” on page 113.)

52
If any of the following conditions occurs,
this indicates a malfunction of the airbags
or seat belt pretensioners. Contact your
Scion dealer as soon as possible.
When the engine switch is turned to
the “ON” position, the light does not
come on or remains on for more than
about 6 seconds or flashes.
The light comes on or starts flashing
while driving.
If any seat belt does not retract or
cannot be pulled out due to a malfunc-
tion 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 Scion
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) front airbags are designed to pro-
vide further protection for the driver
and 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 classifica-
tion sensor, etc.
SRS airbags—
—SRS driver airbag and front
passenger airbag

55
The SRS front airbag system consists
mainly of the following components, and
their locations are shown in the illustra-
tion.1. Front airbag sensors
2. SRS warning light
3. Airbag module for front passenger (airbag and inflator)
4. “AIR BAG ON” and “AIR BAG OFF” indicator lights
5. Front passenger occupant classification system (ECU and sensors)
6. Front passenger ’s seat position sensor
7. Front passenger ’s seat belt buckle switch 8. Driver ’s seat belt buckle switch
9. Driver ’s seat position sensor
10. Airbag sensor assembly 11. Airbag module for driver (airbag and inflator) 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 inflat-
ors very quickly fills the airbags with non
−
toxic gas to help restrain the forward mo-
tion of the occupants. The front 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 safely exit
from the vehicle, you should do so imme-
diately.

58
Do not put anything or any part of
your body on or in front of the
dashboard or steering wheel pad
that houses the front airbag sys-
tem. They might restrict inflation or
cause death or serious injury as
they are projected rearward by the
force of the deploying airbags. Like-
wise, the driver and front passenger
should not hold objects in their
arms or on their knees.
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 a seat accessory, such
as a cushion or seat cover, that
covers the front seat, or do not
modify or replace the upholstery of
the front seat. Such accessories or
changes may prevent the front pas-
senger airbag system from activat-
ing correctly, disable the system or
cause the front passenger airbag to
inflate accidentally, resulting in
death or serious injury.
Failure to follow these instructions
can result in death or serious injury.
Consult your Scion dealer about any
repair and modification.
If you wish to modify your vehicle for
a person with a physical disability,
consult your Scion dealer. It may dan-
gerously interfere with the SRS front
airbags operation.

59
NOTICE
Do not perform any of the following
changes without consulting your
Scion dealer. Such changes can
interfere with proper operation of the
SRS front airbag system in some
cases.
Installation of electronic devices
such as a mobile twoway radio,
cassette tape player or compact
disc player
 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, con-
sole, steering column, steering
wheel or dashboard near the front
passenger airbag
This indicator comes on when the en-
gine switch is turned to the “ON” posi-
tion. It goes off after about 6 seconds.
This means the SRS front airbags are
operating properly.
This warning light system monitors the air-
bag sensor assembly, front airbag sensors,
side and curtain shield airbag sensors, cur-
tain shield airbag sensors, driver ’s seat
position sensor, driver ’s seat belt buckle
switch, front passenger occupant classifica-
tion system, “AIR BAG ON” indicator light,
“AIR BAG OFF” indicator light, front pas-
senger ’s seat belt buckle switch, seat belt
pretensioner assemblies, inflators, intercon-
necting wiring and power sources. (For de-
tails, see “Service reminder indicators and
warning buzzers” on page 113.) If either of the following conditions occurs,
this indicates a malfunction of the airbags
or seat belt pretensioners. Contact your
Scion dealer as soon as possible.
When the engine switch is turned to
the “ON” position, the light does not
come on or remains on for more than
about 6 seconds or flashes.
The light comes on or starts flashing
while driving.
The SRS warning light and “AIR BAG
OFF” indicator light will come on if there
is a malfunction in the front passenger
occupant classification system.

62
The SRS side airbags and curtain shield
airbags will deploy in the event of an
impact that exceeds the set threshold lev-
el (the level of force corresponding to the
impact force produced by an approximate-
ly 1500 kg (3300 lb.) vehicle colliding with
the vehicle cabin from a direction perpen-
dicular to the vehicle orientation at an
approximate speed of 20−30 km/h [12 −18
mph]).
Always wear your seat belts properly.
Collision from the rear
Collision from the front Vehicle rollover
The SRS side airbag and curtain shield
airbags are not generally designed to
inflate if the vehicle is involved in a
front or rear collision, if it rolls over,
or if it is involved in a lowspeed side
collision.The SRS side airbag and curtain shield
airbag system consists mainly of the fol-
lowing components, and their locations are
shown in the illustration.1. Curtain shield airbag modules (airbag and inflator)
2. SRS warning light
3. “AIR BAG ON” and “AIR BAG OFF” indicator lights
4. Front passenger occupant classification system (ECU and sensors)
5. Side airbag modules (airbag and inflator)
6. Curtain shield airbag sensors

63
7. Side and curtain shield airbag sensors
8. Front passenger ’s seat position sensor(for side airbags)
9. Front passenger ’s seat belt buckle switch
10. Airbag sensor assembly The SRS side airbag and curtain shield
airbag system is controlled by the airbag
sensor assembly. The airbag sensor as-
sembly consists of a safing sensor and
airbag sensor.
In a severe side impact, the side and
curtain shield airbag sensor and/or the
curtain shield airbag sensor trigger(s) the
side airbag inflators and/or the curtain
shield airbag inflators. At this time a
chemical reaction in the inflators quickly
fills the airbags with non
−toxic gas to help
restrain the lateral motion of the occu-
pants.
When the airbags inflate, they produce a
fairly 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. Deployment of the airbags happens in a
fraction of a second, so the airbags must
inflate with considerable force. While the
system is desi
gned to reduce serious inju-
ries, it may also cause minor burns or
abrasions and swelling.
Front seats as well as part of the front
and rear pillars, and roof side rail may be
hot for several minutes, but the airbags
themselves will not be hot. The airbags
are designed to inflate only once.
CAUTION
SRS side airbags and curtain shield
airbags inflate with considerable
force. To reduce the possibility of
death or serious injury when they in-
flate, the driver, front passenger and
rear outside passengers must:
Wear their seat belts properly.
Remain properly seated with their
backs upright and against the seats
at all times.
