2004 TOYOTA PRIUS ECU

Toyota strongly urges that the driver and
passengers in the vehicle be properly re-
strained at all times with the seat belts
provided. Failure to do so could increase
the chance of injury and/or the severity of
injury in accidents.
The seat belts provided for your vehicle
are designed for people of adult size,
large enough to properly wear them.
Child. Use a child restraint system ap-
propriate for the child until the child be-
comes large enough to properly wear the
vehicle’s seat belts. For details, see “Child
restraint” on page 78.
If a child is too large for a child restraint
system, the child s hould sit in the rear
seat and must be restrained using the
vehicle’s seat belt. According to accident
statistics, the child is safer when properly
restrained in the rear seat than in the
front seat.
If a child must sit in the front seat, the
seat belts should be worn properly. If an
accident occurs and the seat belts are not
worn properly, the force of the rapid infla-
tion of the airbag may cause death or
serious injury to the child. Do not allow any children to stand up or
kneel on either rear or front seats. An
unrestrained child could suffer serious in-
jury or death during emergency braking or
a collision. Also, do not let the child sit
on your lap. Holding a child in your arms
does not provide sufficient restraint.
Pregnant woman. Toyota recommends the
use of a seat belt. Ask your doctor for
specific recommendations. The lap belt
should be worn securely and as low as
possible over the hips and not on the
waist.
Injured person
. Toyota recommends the
use of a seat belt. Depending on the inju-
ry, first check with your doctor for specific
recommendations.CAUTION
Persons should ride in their seats
properly wearing their seat belts
whenever the vehicle is moving.
Otherwise, they are much more likely
to suffer serious bodily injury or
death in the event of sudden braking
or a collision.
When using the seat belts, observe
the following:
Use the belt for only one person at
a time. Do not use a single belt for
two or more people—even children.
To reduce the risk of sliding under
the lap belt during a collision,
avoid reclining the seatback any
more than needed. The seat belts
provide maximum protection in a
frontal or rear collision when the
driver and the front passenger are
sitting up straight and well back in
the seats. If you are reclined, the
lap belt may slide past your hips
and apply restraint forces directly
to the abdomen. In the event of a
frontal collision, the more the seat
is reclined, the greater the risk of
personal injury.

Be careful not to damage the belt
webbing or hardware. Take care that
they do not get caught or pinched
in the seat or doors.
Inspect the belt system periodically.
Check for cuts, fraying, and loose
parts. Damaged parts should be re-
placed. Do not disassemble or
modify the system.
Keep the belts clean and dry. If
they need cleaning, use a mild soap
solution or lukewarm water. Never
use bleach, dye or abrasive clean-
ers, or allow them to come into
contact with the belt—they may se-
verely weaken the belts. (See
“Cleaning the interior” on page
263.)
Replace the belt assembly (includ-
ing bolts) if it has been used in a
severe impact. The entire assembly
should be replaced even if damage
is not obvious.

Ta bBuckle
Adjust the seat as needed and sit up
straight and well back in the seat. To
fasten your belt, pull it out of the re-
tractor and insert the tab into the
buckle.
You will hear a click when the tab locks
into the buckle.
The seat belt length automatically adjusts
to your size and the seat position.
The retractor will lock the belt during a
sudden stop or on impact. It also may
lock if you lean forward too quickly. A
slow, easy motion will allow the belt to
extend, and you can move around freely. When a passenger ’s shoulder belt is com-
pletely extended and is then retracted
even slightly, the belt is locked in that
position and cannot be extended. This fea-
ture is used to hold the child restraint
system securely. (For details, see “Child
restraint” on page 78.) To free the belt
again, fully retract the belt and then pull
the belt out once more.
If the seat belt cannot be pulled out of the
retractor, firmly pull the belt and release
it. You will then be able to smoothly pull
the belt out of the retractor.CAUTION
After inserting the tab, make sure
the tab and buckle are locked and
that the belt is 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.

If the seat belt extender has been
connected to the driver ’s seat belt
buckle without wearing the seat belt
when using the extender in the
driver ’s seat, the SRS driver ’s air-
bag system will judge that the driv-
er wears the seat belt even if not
wearing it. In this case, the driver ’s
airbag may not activate correctly,
causing death or serious injury in
the event of collision. Be sure to
wear the seat belt with the seat belt
extender.
Be sure to wear the seat belt with-
out the seat belt extender if you
can fasten the seat belt without the
extender.
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.
22p008
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.
When not in use, remove the extender
and store in the vehicle for future use.

Your vehicle is equipped with a crash
sensing and diagnostic module, which will
record the use of the seat belt restraint
system by the driver and passenger when
the SRS front airbags are inflated.CAUTION
The SRS front airbag system is de-
signed only as a supplement to the
primary protection of the driver and
front passenger seat belt systems.
The driver and front passenger can
be killed or seriously injured by the
inflating airbags if they do not wear
the available seat belts properly.
During sudden braking just before
a collision, an unrestrained driver
or front passenger can move for-
ward into direct contact with or
close proximity to the airbag which
may then deploy during the colli-
sion. To ensure maximum protection
in an accident, the driver and all
passengers in the vehicle must
wear their seat belts properly. Wear-
ing a seat belt properly during an
accident reduces the chances of
death or serious injury or being
thrown out of the vehicle. For in-
structions and precautions concern-
ing the seat belt system, see “Seat
belts” on page 56.
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 seat of the vehicle and proper-
ly restrained. The rear seat is the
safest for infants and children. For
instructions concerning the installa-
tion of a child restraint system, see
“Child restraint” on page 78.

71
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 and curtain shield
airbag on the passenger side are activated
even with no passenger in the front seat
or rear seat.
The SRS curtain shield airbags may acti-
vate even when the side airbags are not
activated.
Always wear your seat belt properly.
Your vehicle is equipped with a crash
sensing and diagnostic module, which will
record the use of the seat belt restraint
system by the driver and passenger when
the SRS side airbags and curtain shield
airbags are inflated.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 56.
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
78.

79
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 inju-
ry to the child in the event of a
sudden stop or accident.
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 in-
structions which accompany child re-
straint 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 instructions.
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 top strap” on
page 89.
The child restraint lower anchorages ap-
proved for your vehicle may also be used.
See “—Installation with child restraint low-
er anchorages” on page 91.

CAUTION
After inserting the tab, make sure
the tab and buckle are locked and
that the lap and shoulder portions
of the belt are not twisted.
Do not insert coins, clips, etc. in
the buckle as this may prevent your
child from properly latching the tab
and buckle.
If the seat belt does not function
normally, it cannot protect your
child from death or serious injury.
Contact your Toyota dealer immedi-
ately. Do not install the child re-
straint system on the seat until the
seat belt is fixed.

2. Fully extend the shoulder belt to put itin the lock mode. When the belt is
then retracted even slightly, it cannot
be extended.
To hold the infant seat securely, make
sure the belt is in the lock mode before
letting the belt retract.

3. While pressing the infant seat firmly against the seat cushion and seatback,
let the shoulder belt retract as far as
it will go to hold the infant seat secure-
ly.

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.

4. To remove the infant seat, press thebuckle release button and allow the
belt to retract completely. The belt will
move freely again and be ready to
work for an adult or older child passen-
ger.

(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 instruction about the ap-
plicable age and size of the child as
well as directions for installing the
child restraint system.
