ECU TOYOTA YARIS 2007 2.G Owner's Manual

632007 YARIS HATCHBACK from Feb. ’07Prod. (OM52754U)
In response to a severe side impact, the
SRS side airbags and curtain shield air-
bags work with the seat belts to help
reduce injury by inflating. The SRS side
airbags help reduce injuries mainly to the
driver ’s or front passenger ’s chest and the
SRS curtain shield airbags help reduce
injuries mainly to the driver’s front pas-
senger ’s or rear outside passenger ’s head.
The SRS side airbag on the passenger
seat will not activate if there is no pas-
senger sitting in the front passenger seat.
However, the side airbag on the passen-
ger seat may deploy if luggage is put in
the seat, or the seat belt is buckled up
regardless of the presence of the occu-
pant in the seat. (As for the front passen-
ger occupant classification system, see
“Front passenger occupant classification
system” on page 70 in this Section.)
The SRS curtain shield airbag on the pas-
senger side are activated even with no
passenger in the front seat or rear outside
seat.
The SRS curtain shield airbags may acti-
vate even when the side airbags are not
activated.
Always wear your seat belt properly.CAUTION
The SRS side airbag and curtain
shield airbag system is designed
only as a supplement to the prima-
ry protection of the driver, front
passenger and rear outside passen-
ger seat belt systems. To ensure
maximum protection in an accident,
the driver and all passengers in the
vehicle must wear their seat belts
properly. Wearing a seat belt prop-
erly during an accident reduces the
chances of death or serious injury
or being thrown out of the vehicle.
For instructions and precautions
concerning the seat belt system,
see “Seat belts” on page 42 in this
Section.
Do not allow anyone to lean his/her
head or any part of his/her body
against the door or the area of the
seat, front pillar, rear pillar or roof
side rail from which the SRS side
airbag and curtain shield airbag
deploy even if he/she is a child
seated in the child restraint system.
It is dangerous if the SRS side air-
bag and curtain shield airbag in-
flate, and the impact of the deploy-
ing airbag could cause death or se-
rious injury to the occupant.
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 seats of the vehicle and prop-
erly restrained. The rear seats are
the safest for infants and children.
For instructions concerning the
installation of a child restraint sys-
tem, see “Child restraint” on page
74 in this Section.

The SRS side airbag and curtain shield
airbag system may not activate if the
vehicle is subjected to a collision from
the side at certain angles, or a collision
to the side of the vehicle body other
than the passenger compartment as
shown in the illustration.
The SRS side airbags and curtain shield
airbags are designed to inflate when the
passenger compartment area suffers a se-
vere impact from the side.
Always wear your seat belt properly.
PS13545
Collision from the rear
Collision from the front Vehicle rollover
The SRS side airbags 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.
PS13546
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. SRS warning light
2. “AIRBAG ON” and “AIRBAG OFF” indi- cator lights
3. Front passenger ’s seat belt buckle switch
4. Front passenger occupant classification system (ECU and sensors)
5. Side airbag modules (airbag and inflator)
6. Curtain shield airbag modules (airbag and inflator)

Toyota strongly urges use of a
proper child restraint system which
conforms to the size of the child,
installed on the rear seat. Accord-
ing to accident statistics, the child
is safer when properly restrained in
the rear seat than in the front seat.
Never install a rearfacing child re-
straint system on the front passen-
ger seat even if the “AIRBAG OFF”
indicator light is illuminated. In the
event of an accident, the force of
the rapid inflation of the front pas-
senger airbag can cause death or
serious injury to the child if the
rearfacing child restraint system is
installed on the front passenger
seat.
A forwardfacing child restraint sys-
tem should be allowed to be
installed on the front passenger
seat only when it is unavoidable.
Always move the seat as far back
as possible even if the “AIRBAG
OFF” indicator light is illuminated,
because the front passenger airbag
could inflate with considerable
speed and force. Otherwise, the
child may be killed or seriously in-
jured.
On vehicles with side airbags and
curtain shield airbags, do not allow
the child to lean his/her head or
any part of his/her body against the
door or the area of the seat, front
or rear pillar or roof side rail from
which the side airbags or curtain
shield airbags deploy even if the
child is seated in the child restraint
system. It is dangerous if the side
airbag and curtain shield airbag in-
flate, and the impact could cause
death or serious injury to the child.
Do not use the seat belt extender
when installing a child restraint
system on the front or rear passen-
ger seat. If installing a child re-
straint system with the seat belt
extender connected to the seat belt,
the seat belt will not securely hold
the child restraint system, which
could cause death or serious injury
to the child or other passengers in
the event of collision.
Make sure you have complied with
all installation instructions provided
by the child restraint manufacturer
and that the system is properly se-
cured. If it is not secured properly,
it may cause death or serious injury
to the child in the event of a sud-
den stop or accident.

—Child restraint system
A child restraint system for a small
child or baby must itself be properly
restrained on the seat with the lap por-
tion of the lap/shoulder belt. You must
carefully consult the manufacturer ’s
instructions which accompany the child
restraint system.
To provide proper restraint, use a child
restraint system following the manufactur-
er ’s instructions about the appropriate age
and size of the child for the child restraint
system.
Install the child restraint system correctly
following the instructions provided by its
manufacturer. General directions are also
provided under the following illustrations.
The child restraint system should be
installed on the rear seat. According to
accident statistics, the child is safer when
properly restrained in the rear seat than
in the front seat.
When not using the child restraint system,
keep it secured with the seat belt or place
it somewhere other than the passenger
compartment. This will prevent it from in-
juring passengers in the event of a sud-
den stop or accident.Child restraint systems are classified into
the following 3 types depending on the
child’s age and size.
(A) Infant seat
(B) Convertible seat
(C) Booster seat
Install the child restraint system following
the instructions provided by its manufac-
turer.
Your vehicle has anchor brackets for se-
curing the top strap of a child restraint
system.
For instructions about how to use the an-
chor bracket, see “—Using a top strap” on
page 89 in this Section.
The child restraint lower anchorages
approved for your vehicle may also be
used. See “—Installation with child
restraint lower anchorages” on page 92 in
this Section.

PS13562
CAUTION
Never install a rearfacing child re-
straint system on the front passen-
ger seat even if the “AIRBAG OFF”
indicator light is illuminated. In the
event of an accident, the force of
the rapid inflation of the front pas-
senger airbag can cause death or
serious injury to the child if the
rearfacing child restraint system is
installed on the front passenger
seat.
PS13563
Do not install a child restraint sys-
tem on the rear seat if it interferes
with the lock mechanism of the
front seats. Otherwise, the child or
front seat occupant(s) may be killed
or seriously injured in case of sud-
den braking or a collision.
If the driver ’s seat position does
not allow sufficient space for safe
installation, install the child re-
straint system on the rear right
seat.
PS13564
Same angleSame position
Split seat: When installing a child
restraint system in the rear seat
center position, adjust both seat
cushions to the same position and
align both seatbacks at the same
angle. Otherwise, the child restraint
system cannot be securely re-
strained and this may cause death
or serious injuries in a collision.

(B) CONVERTIBLE SEAT INSTALLATION
A convertible seat must be used in for-
wardfacing or rearfacing position de-
pending on the age and size of the
child. When installing, follow the
manufacturer ’s instructions about the
applicable age and size of the child as
well as directions for installing the
child restraint system.Install the child restraint system on the
front passenger seat only when it is un-
avoidable. Your vehicle is equipped with a
front passenger occupant classification
system. In order to activate the occu
pant
classification system correctly, install the
forward −facing child restraint system on
the front passenger seat in the following
order:
1. Turn the ignition key to the “ON” posi- tion.
2. Move the front passenger seat to the rearward position.
3. If you must install the child restraint system on the front passenger seat,
put the child restraint system putting
your weight on the front passenger
seat.
4. Insert the seat belt tab into the seat belt buckle.
5. Fully extend the shoulder belt to put it in the lock mode. When the belt is
then retracted even slightly, it cannot
be extended. To hold the seat securely,
make sure the belt is in the lock mode
before letting the belt retract. 6. While pressing the convertible seat
firmly against the seat cushion and
seatback, let the shoulder belt retract
as far as it will go to hold the convert-
ible seat securely.
CAUTION
Push and pull the child restraint sys-
tem in different directions to be sure
it is secure. Follow all the installation
instructions provided by its manufac-
turer.
7. Put a child on the child restraint sys-tem and secure the child, complying
with the instructions provided by the
child restraint system manufacturer.

The “AIRBAG OFF” indicator light should
be illuminated when the ignition key is in
the “ON” position and the child is in the
child restraint system after following these
procedures. The “AIRBAG OFF” indicator
light indicates the SRS front passenger
airbag and side airbag on the passenger
side will not deploy. If the “AIRBAG ON”
indicator light is illuminated, do the follow-
ing procedure:1. Turn the ignition off.
2. Remove the child restraint system.
3. When reinstalling a child restraint sys- tem, make sure the seatback does not
press the child restraint system into
the seat cushion. If this occurs, adjust
the seatback angle slightly.
4. Then make sure the head restraint is not pressing the child restraint system
into the seat cushion. If this occurs,
raise the head restraint.
5. Turn the ignition on again. The “AIRBAG OFF” indicator light should
be illuminated. If the “AIRBAG ON” indica-
tor light is illuminated when the ignition
key is turned to the “ON” position, then
the SRS front passenger airbag and side
airbag on the passenger side may deploy
in an accident. Do not drive the vehicle
in this condition. Remove the child re-
straint system and contact your Toyota
dealer.
CAUTION
Never install a rearfacing child
restraint system on the front
passenger seat. A forwardfacing
child restraint system should only
be installed on the front passenger
seat when unavoidable. If you must
install the child restraint system on
the front passenger seat, put the
seat in its most rearward position,
and install the forwardfacing child
restraint system in the proper
order. Otherwise, the front
passenger occupant classification
system cannot detect the presence
of the child restraint system and
the front passenger airbag and side
airbag on the front passenger seat
could deploy.
PS13561
CAUTION
Split seat: When installing a rear
facing child restraint system in the
rear seat, move the rear seat to the
rearmost lock position to prevent
the child restraint system from in-
terfering with the front seat. Other-
wise, the child restraint system may
not be properly secured. In the
event of an accident, this may
cause death or serious injury.
