—Front seat belt pretensioners
SY13021a
The driver and front passenger ’s seat
belt pretensioners are designed to be
activated in response to a severe fron-
tal impact.
When the airbag sensor detects the shock
of a severe frontal impact, the front seat
belts are quickly drawn back in by the
retractors so that the belts snugly restrain
the front seat occupants.
The front seat belt pretensioners are acti-
vated even with no passenger in the front
seat.
Collisions occurring at certain speeds and
angles may cause the seat belt preten-
sioners and SRS airbags not to operate
all together.
SP13504
This indicator comes on when the ignition
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 airbag sensors, door side air-
bag sensors, front seat belt pretensioner
assemblies, inflators, warning light, inter-
connecting wiring and power sources. (For
details, see “Service reminder indicators
and warning buzzers” on page 86 in Sec-
tion 15.)

When the front seat belt pretensioners are
activated, an operating noise may be
heard and a small amount of smokelike
gas may be released. This gas is harm-
less and does not indicate that a fire is
occurring.
Once the front seat belt pretensioners
have been activated, the seat belt retrac-
tors remain locked.
CAUTION
Do not modify, remove, strike or open
the front seat belt pretensioner as-
semblies, airbag sensor or surround-
ing area or wiring. Doing any of
these may cause sudden operation of
the front seat belt pretensioners or
disable the system, which could re-
sult in death or serious injury.
Failure to follow these instruction can
result in death or serious injuries.
Consult your Toyota dealer about any
repairs and modifications.
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.

SU13019
In the following cases, contact your Toyota
dealer as soon as possible:
The front part of the vehicle (shaded
in the illustration) was involved in an
accident that was not severe enough to
cause the front seat belt pretensioners
to operate.
Either front seat belt pretensioner as-
sembly or surrounding area is
scratched, cracked, or otherwise dam-
aged.
SY13024
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.
In response to a severe frontal impact,
the SRS front airbags work together with
the seat belts to help reduce injury by
inflating. The SRS front airbags help to
reduce injuries mainly to the driver ’s or
front passenger ’s head or chest caused by
directly hitting the steering wheel or dash-
board. The front passenger airbag is acti-
vated even with no passenger in the front
seat.
Be sure to wear your seat belt properly.
CAUTION
The driver or front passenger who is
too close to the steering wheel or
dashboard during airbag deployment
can be killed or seriously injured.
Toyota strongly recommends that:
The driver sit as far back as pos-
sible from the steering wheel while
still maintaining control of the ve-
hicle.
The front passenger sit as far back
as possible from the dashboard.
All vehicle occupants be properly
restrained using the available seat
belts.

SRS driver and front
passenger airbags

SP13504
This indicator comes on when the igni-
tion key is turned to the “ON” position.
It goes off after about 6 seconds. This
means the SRS front airbags are oper-
ating properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side airbag sensors, door side air-
bag sensors, front seat belt pretensioner
assemblies, inflators, warning light, inter-
connecting wiring and power sources. (For
details, see “Service reminder indicators
and warning buzzers” on page 86 in Sec-
tion 15.)The SRS front airbags are designed to
deploy in severe (usually frontal) colli-
sions where the magnitude and duration
of the forward deceleration of the ve-
hicle exceeds the designed threshold
level.
The SRS front airbags will deploy if the
severity of the impact is above the de-
signed threshold level, comparable to an
approximate 25 km/h (15 mph) collision in
the U.S.A. and 30 km/h (18 mph) collision
in Canada when the vehicle has the im-
pact straight into a fixed barrier that does
not move or deform.
However, this threshold velocity will be
considerably higher if the vehicle strikes
an object, such as a parked vehicle or
sign pole, which can move or deform on
impact, or if the vehicle is involved in an
underride collision (e.g. a collision in
which the front of the vehicle “underrides”,
or goes under, the bed of a truck, etc.).
It is possible that in some collisions
where the forward deceleration of the ve-
hicle is very close to the designed thresh-
old level, the SRS front airbags and the
seat belt pretensioners may not activate
together.
For the safety of all occupants, always
wear your seat belts properly.
SU13114
Collision from the side
Vehicle rollover
Collision from the rear
The SRS front airbags are generally not
designed to inflate if the vehicle is in-
volved in a side or rear collision, if it
rolls over, or if it is involved in a low
speed frontal collision. But, when
ever a
collision of any type causes sufficient
forward deceleration of the vehicle, de-
ployment of the SRS front airbags may
occur.
2003 ECHO from Aug. ’02 Prod. (OM52481U)

Deployment of the airbags happens in a
fraction of a second, so the airbags must
inflate with considerable force. While the
system is designed to reduce serious inju-
ries, primarily to the head and chest, it
may also cause other, less severe injuries
to the face, chest, arms and hands. These
are usually in the nature of minor burns
or abrasions and swelling, but the force of
a deploying airbag can cause more seri-
ous injuries, especially if an occupant’s
hands, arms, chest or head are in close
proximity to the airbag module at the time
of deployment. This is why it is important
for the occupant to: avoid placing any
object or part of the body between the
occupant and the airbag module; sit
straight and well back into the seat; wear
the available seat belt properly; and sit as
far as possible from the airbag module,
while still maintaining control of the ve-
hicle.
Parts of the airbag module (steering wheel
hub, airbag cover and inflator) may be hot
for several minutes after deployment, so
do not touch! The airbags inflate only
once. The windshield may be damaged by
absorbing some of the force of the inflat-
ing airbag.CAUTION
The SRS airbag system is designed
only as a supplement to the prima-
ry protection of the driver side and
front passenger side seat belt sys-
tems. The front seat occupants 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
instructions and precautions con-
cerning the seat belt system, see
“Seat belts” in this section.
Improperly seated and/or restrained
infants and children can be killed
or seriously injured by the deploy-
ing front 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” in this section.

SY13031
Do not sit on the edge of the seat
or lean over the dashboard when
the vehicle is in use, since the
front airbags inflate with consider-
able speed and force. Otherwise,
you may be killed or seriously in-
jured. Sit up straight and well back
in the seat, and always use your
seat belt properly.
SY13032
Do not allow a child to stand up or
to kneel on the front passenger
seat, since the front airbag inflates
with considerable speed and force.
Otherwise, the child may be killed
or seriously injured.
Do not hold a child on your lap or
in your arms. Use a child restraint
system in the rear seat. For instruc-
tions concerning the installation of
a child restraint system, see “Child
restraint” on page 54 in this sec-
tion.
SY13033
Do not put objects or your pets on
or in front of the dashboard or
steering wheel pad that houses the
front airbag system. They might re-
strict inflation or cause death or
serious injury as they are projected
rearward by the force of deploying
airbags. Likewise, the driver and
front passenger should not hold ob-
jects in their arms or on their
knees.

SU13030
In the following cases, contact your Toyota
dealer as soon as possible:
The SRS front airbags have been in-
flated.
The front part of the vehicle (shaded
in the illustration) was involved in an
accident that was not severe enough to
cause the SRS front airbags to inflate.
The pad part of the steering wheel or
front passenger airbag cover (shaded
in the illustration) is scratched,
cracked, or otherwise damaged.
NOTICE
Do not disconnect the battery cables
before contacting your Toyota dealer.
SRS side airbags
SU13134
The SRS (Supplemental Restraint Sys-
tem) side 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.
In response to a severe side impact, the
SRS side airbags work together with the
seat belts to help reduce injury by inflat-
ing. The SRS side airbags help to reduce
injuries mainly to the driver’s or front pas-
senger ’s chest. The SRS side airbag on
the passenger seat is activated even with
no passenger in the front seat.
Be sure to wear your seat belt properly.
2003 ECHO from Aug. ’02 Prod. (OM52481U)

49
CAUTION
SRS side airbags inflate with consid-
erable force. To avoid potential death
or serious injury when they inflate,
the driver and front passenger must:
Wear their seat belts properly.
Remain properly seated with their
back upright and against the seat at
all times.
SP13504
This indicator comes on when the ignition
key is turned to the “ON” position. It goes
off after about 6 seconds. This means the
SRS side airbags are operating properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side airbag sensors, door side air-
bag sensors, front seat belt pretensioner
assemblies, inflators, warning light, inter-
connecting wiring and power sources. (For
details, see “Service reminder indicators
and warning buzzers” on page 86 in Sec-
tion 15.)
SU13125
The SRS side 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 illustra-
tion.
The SRS side airbags are designed to
inflate when the passenger compartment
area suffers a severe impact from the
side.
For the safety of all occupants, always
wear your seat belts properly.
