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 and curtain shield airbag sen-
sors, curtain shield airbag sensors, driv-
er ’s seat position sensor, driver ’s seat belt
buckle switch, front passenger occupant
classification system and indicator light,

ors, warning light, interconnecting wiring
and power sources. (For details, see “Ser-
vice reminder indicators and warning buzz-
ers” in Section 1
−6.)
If either of the following conditions occurs,
this indicates a malfunction of the airbags
or seat belt pretensioners. Contact your
Toyota dealer as soon as possible.

group identified in TABLE 1 is oc-
cupying the right front passenger
seating position.
When the passenger airbag manual
on− off switch is turned off, the pas-
senger airbag will not inflate in a
collision and turning off the pas-
senger airbag can reduce the occu-
pant protection which your vehicle
safety systems can provide to you
in certain accidents and increase
the likelihood of serious personal
injuries.
For details, see “SRS driver airbag
and front passenger airbag” in this
Section.
The SRS (Supplemental Restraint Sys-
tem) side airbags and curtain shield air-
bags are designed to provide further
protection for the driver, front passen-
ger and rear outside passengers in
addition to the primary safety protec-
tion provided by the seat belts.

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.
Vehicles with separate seat—The SRS
side airbag on the passenger seat will not
activate if there is no passenger sitting in
the front passenger seat. However, the
side airbag on the passenger seat may
deploy if luggage is put in the seat, or the
seat belt is buckled up, regardless of the
presence of an occupant in the seat. (As
for the front passenger occupant classifi-
cation system, see “Front passenger occu-
pant classification system” in this Sec-
tion.) Roll sensing function:
In response to a vehicle rollover, the cur-
tain shield airbags on both sides work
with the seat belts to help reduce injury
by inflating. The curtain shield airbags
help reduce injuries mainly to the driver ’s
or front passenger ’s head and help pre-
vent them from being thrown out of the
vehicle. (This function can be turned off
if inflation is not desired. See “Roll sens-
ing of curtain shield airbags off switch” in
this Section.)
The SRS curtain shield airbag on the pas-
senger side are activated even with no
passenger in the front seat or rear outside
seat.
The SRS curtain shield airbags may acti-
vate even when the side airbags are not
activated.
Always wear your seat belt properly.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” in this Section.

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 p illar, 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” in this
Section.
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 are designed to
inflate when the passenger compartment
area suffers a severe impact from the
side.
The curtain shield airbags are designed to
inflate when the passenger compartment
area suffers a severe impact from the
side or vehicle rollover.
Always wear your seat belts properly.

Collision from the rear
Collision from the front Vehicle rollover
The SRS side airbags are not generally
designed to inflate if the vehicle is in-
volved in a front or rear collision, if it
rolls over, or if it is involved in a low −
speed side collision.
The angle of
vehicle tip −up
is manual Skidding vehicle
hitting a curb
stone
The curtain shield airbags may inflate
if the angle of vehicle tip
−up is margin-
al or if the skidding vehicle’s tires hit
a curb stone laterally as shown in the
illustration.
Collision from
the front Collision from
the rear
Pitch end over end
The curtain shield airbags are not gen-
erally designed to inflate if the vehicle
is involved in a front or rear collision,
if it pitches end over end, or if it is
involved in a low −speed side collision.

The SRS side and curtain shield airbags
may deploy if a serious impact occurs
to the underside of your vehicle. Some
examples are shown in the illustration.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. Separate seat only—Front passenger occupant classification indicator light
3. Curtain shield airbag modules (airbag and inflator)
4. Separate seat only—Front passenger occupant classification system (ECU
and sensors)
5. Side airbag modules (airbag and inflator)
6. Curtain shield airbag sensors 7. Side and curtain shield airbag sensors
8. Front passenger ’s seat belt buckle
switch
9. Airbag sensor assembly
The SRS side airbag and curtain shield
airbag system is controlled by the airbag
sensor assembly. The airbag sensor as-
sembly consists of a safing sensor and
airbag sensor.
In a severe side impact, the side and
curtain shield airbag sensor and/or the
curtain shield airbag sensor trigger(s) the
side airbag inflators and/or the curtain
shield airbag inflators. At this time a
chemical reaction in the inflators quickly
fills the airbags with non −toxic gas to help
restrain the lateral motion of the occu-
pants.
In a vehicle rollover, the airbag sensor
assembly triggers the curtain shield airbag
inflator. At this time, a chemical reaction
in the inflators quickly fills the airbags
with non −toxic gas to help restrain the
lateral motion of the occupants.

2005 TUNDRA from Aug. ’04 Prod. (OM34427U)
When the airbags inflate, they produce a
fairly 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, it may also cause minor burns or
abrasions and swelling.
Front seats as well as parts of the front
and rear pillars, and roof side rail may be
hot for several minutes, but the airbags
themselves will not be hot. The airbags
are designed to inflate only once.CAUTION
SRS side airbags and curtain shield
airbags inflate with considerable
force. To reduce the possibility of
death or serious injury when they in-
flate, the driver, front passenger and
rear outside passengers must:
Wear their seat belts properly.
Remain properly seated with their
backs upright and against the seats
at all times.
Do not allow anyone to lean against
the door when the vehicle is in use,
since the side airbag and curtain
shield airbag could inflate with con-
siderable speed and force. Other-
wise, he/she may be killed or seri-
ously injured. Special care should
be taken especially when you have
a small child in the vehicle.
Sit up straight and well back in the
seat, distributing your weight evenly
in the seat. Do not apply excessive
weight to the outer side of the
seats with a side airbag, and to the
front pillar, rear pillar and roof side
rail with a curtain shield airbag.
