The SRS warning light and the front
passenger occupant classification indi-
cator light or passenger airbag off indi-
cator light will indicate “OFF” if there
is a malfunction in the passenger air-
bag off switch.
CAUTION
Do not turn off the passenger air-
bag off switch except when a mem-
ber of a passenger risk group iden-
tified in TABLE 1 is occupying the
right front passenger seating posi-
tion.
When the passenger airbag off
switch is turned off, the passenger
airbag will not inflate in a collision
and turning off the passenger air-
bag can reduce the occupant
protection which your vehicle safety
systems can provide to you in cer-
tain accidents and increase the like-
lihood of serious personal injuries.
For details, see “SRS driver airbag
and front passenger airbag” in this
Section.
The SRS (Supplemental Restraint Sys-
tem) airbags are designed to provide
further protection for the driver and
front passenger in addition to the pri-
mary safety protection provided by the
seat belts.
Your vehicle is equipped with “ADVANCED
AIRBAGS” designed based on US motor
vehicle safety standards (FMVSS208). The
airbag system controls airbag deployment
power for the driver and front passenger.
The driver airbag system consists of the
driver seat’s position sensor etc. The front
passenger ’s airbag system consists of the
front passenger occupant classification
sensor etc. In response to a severe frontal impact,
the SRS front airbags work with the seat
belts to help reduce injury by inflating.
The SRS front airbags help reduce injuries
mainly to the driver’s or front passenger’s
head or chest caused by hitting the ve-
hicle interior.
The SRS front passenger airbag will not
activate if there is no passenger sitting in
the front passenger seat. However, the
front passenger airbag may deploy if lug-
gage 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 classification
system, see “Front passenger occupant
classification system” in this Section.)
Always wear your seat belt properly.

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. Front passenger occupant classification indicator light
3. Airbag module for front passenger (airbag and inflator)
4. Passenger ’s seat position sensor
5. Front passenger occupant classification system (ECU and sensors)
6. Front passenger ’s seat belt buckle switch
7. Driver ’s seat belt buckle switch
8. Driver ’s seat position sensor
9. Airbag sensor assembly
10. Airbag module for driver (airbag and inflator)
11. SRS warning light 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 infla-
tors very quickly fills the air
bags with
non− toxic gas to help restrain the forward
motion of the occupants. The airbags then
quickly deflate, so that there is no ob-
struction 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.

2006 TUNDRA from Oct. ’06 Prod. (OM 34458U)
Do not put anything or any part of
your body on or in front of the
dashboard or steering wheel pad
that houses the airbag system. They
might restrict inflation or cause
death or serious injury as they are
projected rearward by the force of
the deploying 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, dashboard
near the front passenger airbag,
front passenger airbag cover, front
passenger airbag or airbag sensor
assembly. Doing so may prevent the
front airbag system from activating
correctly, cause sudden activation
of the system or disable the sys-
tem, which could result in death or
serious injury.
Split bench seat—Do not use seat
accessory, such as a cushion or
seat cover, that covers the front
seat, or do not modify or replace
the upholstery of the front seat.
Such accessories or changes may
prevent the front passenger airbag
system from activating correctly,
disable the system or cause the
front passenger airbag to inflate ac-
cidentally, resulting in death or seri-
ous injury.
Failure to follow these instructions
can result in death or serious injury.
Consult your Toyota dealer about any
repair and modification.
If you wish to modify your vehicle for
a person with physical disability, con-
sult your Toyota dealer. It may dan-
gerously interfere with the SRS front
airbags operation.
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

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. Front passenger occupant classification indicator light
3. Curtain shield airbag modules (airbag and inflator)
4. 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.
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.

the “OFF” switch.
To turn on the automatic function again,
push the “AUTO” switch.
Adjust it before driving so that the rear
view is in the best condition.
When the inside air temperature is low, it
may take a little longer for the mirror to
darken in response to the detection of
headlights.
CAUTION
Do not adjust the mirror while the
vehicle is moving. Doing so may
cause the driver to mishandle the ve-
hicle and an accident may occur re-
sulting in death or serious injuries.
