2004 TOYOTA PRIUS warning light

22p206
The SRS front airbag system consists
mainly of the following components and
their locations are shown in the illustra-
tion.1. Front airbag sensors
2. SRS warning light
3. Airbag module for front passenger (air- bag and inflator)
4. Driver ’s seat belt buckle switch
5. Driver ’s seat position sensor
6. Airbag sensor assembly
7. Airbag module for driver (airbag and inflator) The airbag sensor assembly consists of a
safing sensor and airbag sensor.
The front airbag sensors constantly moni-
tor the forward deceleration of the vehicle.
If an impact results in a forward decelera-
tion beyond the designed threshold level,
the system triggers the airbag inflators. At
this time a chemical reaction in the inflat-
ors very quickly fills the airbags with non
−
toxic gas to help restrain the froward mo-
tion of the occupants. The front airbags
then quickly deflate, so that there is no
obstruction of the driver’s vision should it
be necessary to continue driving.
When the airbags inflate, they produce a
loud noise and release some smoke and
residue along with non −toxic gas. This
does not indicate a fire. This smoke may
remain inside the vehicle for some time,
and may cause some minor irritation to
the eyes, skin or breathing. Be sure to
wash off any residue as soon as possible
to prevent any potential skin irritation with
soap and water. If you can safely exit
from the vehicle, you should do so imme-
diately. 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, 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 is 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.

NOTICE
Do not perform any of the following
changes without consulting your
Toyota dealer. Such changes can in-
terfere with proper operation of the
SRS front airbag system in some
cases.
Installation of electronic devices
such as a mobile twoway radio,
cassette tape player or compact
disc player
 Modification of the suspension sys-
tem
 Modification of the front end struc-
ture
 Attachment of a grille guard (bull
bar, kangaroo bar, etc.), snowplow,
winches or any other equipment to
the front end
 Repairs made on or near the front
fenders, front end structure, con-
sole, steering column, steering
wheel or dashboard near the front
passenger airbag
22p010a
This indicator comes on when the “IG
ON” mode is enabled. It goes off after
about 6 seconds. This means the SRS
front airbags are operating properly.
The warning light system monitors the air-
bag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sen-
sors, curtain shield airbag sensors,
driver ’s seat position sensor, driver ’s seat
belt buckle switch, front passenger ’s seat
belt buckle switch, seat belt pretensioner
assemblies, warning light, interconnecting
wiring and power sources. (For details,
see “Service reminder indicators and
warning buzzers” on page 117.) If any of the following conditions occurs,
this indicates a malfunction of the airbags
or seat belt pretensioners. Contact your
Toyota dealer as soon as possible.
When the “IG
−ON” mode is enabled,
the light does not come on or remains
on for more than 6 seconds.
The light comes on while driving.

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 belts properly.
22p026c
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.
22p027a
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. Curtain shield airbag modules (airbag and inflator)
3. Side airbag modules (airbag and inflator)
4. Curtain shield airbag sensors
5. Side and curtain shield airbag sensors
6. Airbag sensor assembly

76
Do not disassemble or repair the
front and rear pillars and roof side
rails containing the curtain shield
airbags. Such changes may disable
the system or cause the curtain
shield airbags to inflate accidental-
ly, resulting in death or serious in-
jury.
Failure to follow these instructions
can result in death or serious injury.
Consult your Toyota dealer about any
repair and modification.NOTICE
Do not perform any of the following
changes without consulting your
Toyota dealer. Such changes can
interfere with proper operation of the
SRS side airbag and curtain shield
airbag system in some cases.
 Installation of electronic devices
such as a mobile twoway radio,
cassette tape player or compact
disc player
 Modification of the suspension sys-
tem
 Modification of the side structure of
the passenger compartment
 Repairs made on or near the con-
sole or front seat
22p010a
This indicator comes on when the “IG
ON” mode is enabled. It goes off after
about 6 seconds. This means the SRS
side airbags and curtain shield airbags
are operating properly.
The warning light system monitors the air-
bag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sen-
sors, curtain shield airbag sensors,
driver ’s seat position sensor, driver ’s seat
belt buckle switch, front passenger ’s seat
belt buckle switch, seat belt pretensioner
assemblies, warning light, interconnecting
wiring and power sources. (For details,

At the first blinking of the light, the master
warning light in the instrument cluster
comes on and the message appears on
the multi−information display to remind the
driver to fill fuel.
On inclines or curves, due to the move-
ment of fuel in the tank, the low fuel level
indicator light may come on earlier than
usual.
24p004e
This meter displays the odometer and
two trip meters.
1. Odometer—Shows the total distance the vehicle has been driven.
2. Two trip meters—Show two different distances independently driven since
the last time each trip meter was set
to zero.
You can use one trip meter to calculate
the fuel economy and the other to
measure the distance on each trip. All
trip meter data is cancelled if the elec-
trical power source is disconnected.
3. Trip meter reset button—Resets the two trip meters to zero, and also
change the meter display. To change the meter display, quickly
push and release the button. The meter
display changes in the order from the
odometer to trip meter A to trip meter
B, then back to the odometer each
time you push.
To reset the trip meter A to zero, dis-
play the meter A reading, then push
and hold the button until the meter is
set to zero. The same process can be
applied for resetting the trip meter B.
