CAUTION
After inserting the tab, make sure
the tab and buckle are locked and
that the seat belt extender 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. It cannot
protect an adult occupant or your
child from injury.
The driver and front outside passen-
ger ’s seat belt pretensioners are de-
signed to be activated in response to
a severe frontal impact.
When the airbag sensor detects the shock
of a severe frontal impact, the front out-
side seat belts are quickly drawn back in
by the retractors so that the belts snugly
restrain the front outside seat occupants.
The front outside seat belt pretensioners
are activated even with no passenger in
the front outside seat.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 front outside seat belt pre-
tensioners are operating properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side airbag sensors, driver ’s seat
position sensor, driver ’s seat belt buckle
switch, front seat belt pretensioner assem-
blies, inflators, warning light, interconnect-
ing wiring and power sources. (For details,
see “Service reminder indicators and
warning buzzers” in Section 15.)

The front outside seat belt pretensioner
system mainly consists of the following
components and their locations are shown
in the illustration.
1. Front airbag sensors
2. SRS warning light
3. Front seat belt pretensioner assemblies
4. Airbag sensor assembly
The front outside seat belt pretensioners
are controlled by the airbag sensor as-
sembly. The airbag sensor assembly con-
sists of a safing sensor and airbag sen-
sor.When the front outside seat belt preten-
sioners are activated, an operating noise
may be heard and a small amount of
smokelike gas may be released. This gas
is harmless and does not indicate that a
fire is occurring.
Once the front outside seat belt preten-
sioners have been activated, the seat belt
retractors 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 so may
cause sudden operation of the front
outside seat belt pretensioners or dis-
able the system, which could result in
death or serious injury.
Failure to follow these instructions
can result in death or serious inju-
ries. 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 outside 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

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, driver ’s seat
position sensor, driver ’s seat belt buckle
switch, front seat belt pretensioner assem-
blies, inflators, warning light, interconnect-
ing wiring and power sources. (For details,
see “Service remainder indicators and
warning buzzers” in Section 15.)The SRS front airbag system is de-
signed to activate in response to a se-
vere frontal impact within the shaded
area between the arrows in the illustra-
tion.
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 impacting straight into a
fixed barrier that does not move or de-
form.
If the severity of the impact is below the
above threshold level, the SRS front air-
bags may not deploy.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.).
For the safety of all occupants, always
wear your seat belts properly.

Collision from the sideCollision from the rear
Vehicle rollover
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.

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. Airbag module for driver
(airbag and inflator)
3. Airbag module for front passenger
(airbag and inflator)
4. Driver ’s seat belt buckle switch
5. Driver ’s seat position sensor
6. Airbag sensor assembly
7. SRS warning light
The airbag sensor assembly consists of a
safing sensor and airbag sensor.

’03 AVALON U (L/O 0206)
632003 AVALON (OM41401U)
In a severe frontal impact, the sensor de-
tects deceleration and the system triggers
the airbag inflators. At this time a chemi-
cal reaction in the inflators quickly fills the
airbags with nontoxic gas to help restrain
the forward motion of the occupants.
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 designed 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.

’03 AVALON U (L/O 0206)
662003 AVALON (OM41401U)
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 the deploy-
ing airbags. Likewise, 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, front passen-
ger airbag cover, front passenger
airbag or airbag sensor assembly.
Doing so may cause sudden SRS
front airbag inflation or disable the
system, which could result in death
or serious injury.
Failure to follow these instructions
can result in death or serious injury.
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
SRS front airbag system in some
cases.

The SRS (Supplemental Restraint Sys-
tem) side airbags are designed to pro-
vide further protection for occupants in
the following seats in addition to the
primary safety protection provided by
the seat belts.
Vehicles with bucket front seats—The
SRS side airbags are designed to pro-
tect the driver and front passenger.
Vehicles with bench type front seats—
The SRS side airbags are designed to
protect the driver and rightfront pas-
senger. They are not designed to pro-
tect occupant in the center position.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.
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, driver ’s seat
position sensor, driver ’s seat belt buckle
switch, front seat belt pretensioner assem-
blies, inflators, warning light, interconnect-
ing wiring and power sources. (For details,

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.

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.The SRS side airbag system consists
mainly of the following components, and
their locations are shown in the illustra-
tion.
1. SRS warning light
2. Airbag sensor assembly
3. Side airbag modules
(airbag and inflator)
4. Side airbag sensors
The SRS side airbag system is controlled
by the airbag sensor assembly. The airbag
sensor assembly consists of a safing sen-
sor and airbag sensor.

’03 AVALON U (L/O 0206)

In a severe side impact, the side airbag
sensor triggers the side airbag inflators.
At this time a chemical reaction in the
inflators quickly fills the airbags with non
toxic gas to help restrain the lateral mo-
tion of the occupants.
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 designed to reduce serious inju-
ries, it may also cause minor burns or
abrasions and swelling.
Front seats may be hot for several min-
utes, but the airbags themselves will not
be hot. The airbags are designed to inflate
only once.CAUTION
The SRS side airbag system is de-
signed only as a supplement to the
primary protection of the driver
side and front passenger side 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 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 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.
Do not allow a child to lean his/her
head or any part of his/her body
against the front door or the area
of the seat from which the side air-
bag deploys even if he/she is
seated in the child restraint system.
It is dangerous if the side airbag
inflates, and 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.
