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 it is involved in an underride
collision (e.g. a collision in which the nose
of the vehicle “underrides”, or goes under,
the bed of a truck, etc.).
It is possible that in some collisions at the
lower zone of airbag sensor detection and
activation, the SRS airbags and seat belt
pretensioners will not operate all together.
For the safety of all occupants, always
wear your seat belts properly.
SU13114
Collision from the sideVehicle rollover
Collision from the rear
The SRS front airbags are not designed
to inflate if the vehicle is involved in a
side or rear collision, if it rolls over, or
if it is involved in a lowspeed frontal
collision.
SU13119
Hitting a curb,
edge of pavement
or hard material
Falling into or
jumping over a
deep hole
Landing hard or vehicle falling
The SRS front airbags may deploy if a
serious impact occurs to the underside
of your vehicle. Some examples are
shown in the illustration.

The SRS airbag system consists mainly of
the following components, and their loca-
tions are shown in the illustration.1. Front airbag sensors
2. SRS warning light
3. Airbag module for driver (airbag and inflator)
4. Airbag module for front passenger (air- bag and inflator)
5. Airbag sensor assembly
The airbag sensor assembly consists of a
safing sensor and airbag sensor. In a severe frontal impact, the sensors
detect deceleration and the system trig-
gers the airbag inflators. At this time a
chemical reaction in the inflators quickly
fills the air
bags with nontoxic gas to help
restrain the forward motion of the occu-
pants.
When the airbags inflate, they produce a
fairly loud noise and release some smoke
and residue along with nontoxic gas. This
does not indicate a fire. This gas is nor-
mally harmless; however, for those who
have delicate skin, it may cause a minor
skin irritation. Be sure to wash off any
residue as soon as possible to prevent
any potential skin irritation.
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.
Parts of the airbag module (steering wheel
hub, dashboard) may be hot for several
minutes, but the airbags themselves will
not be hot. The airbags are designed to
inflate only once. A crash severe enough to inflate the air-
bags may break the windshield as the
vehicle buckles. In vehicles with a pas-
senger airbag the windshield may also be
damaged by absorbing some of the force
of the inflating 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.
SU13120
Never put a rearfacing child re-
straint system on the front passen-
ger seat because the force of the
rapid inflation of the front passen-
ger airbag can cause death or seri-
ous injury to the child.

2002MY ECHO (U) L/O0109
452002 ECHO (OM52463U)
SZ13078
Move seat
fully back
A forwardfacing child restraint sys-
tem should be allowed to be put on
the front passenger seat only when
it is unavoidable. Always move the
seat as far back as possible, be-
cause the force of the deploying
front passenger airbag could cause
death or serious injury to the child.
On vehicles with side airbags, do
not allow the child to lean against
the front door or around the front
door even if the child is seated in
the child restraint system. It is dan-
gerous if the side airbag inflates,
because the impact could cause
death or serious injury to the child.
For instructions concerning the
installation of a child restraint sys-
tem, 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.

2001MY ECHO (U) L/O0008
462002 ECHO (OM52463U)
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 53 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.
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 or front pas-
senger airbag cover, front passen-
ger airbag or airbag sensor assem-
bly. Doing any of these may cause
sudden SRS front airbag inflation or
disable the system, which could re-
sult in death or serious injury.
Failure to follow these instructions
can result in death or serious injury.

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.
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.

SU13118
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 side airbags are operat-
ing 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 82 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.
SU13126
Collision from the rear
Collision from the front Vehicle rollover
The SRS side airbags are not 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.
