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 airbags are operating
properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, inflators, warning light, interconnect-
ing wiring and power sources. (For details,
see “Service reminder indicators and
warning buzzers” in Section 1− 5.)
TABLE 1: A PASSENGER RISK GROUP
Infant. An infant (less than 1 year old) who must ride in the front seat because:
Vehicle has no rear seat;
Vehicle has a rear seat too small to accommodate a rear −facing infant seat;
or
The infant has a medical condition which, according to the infant’s physician,
makes it necessary for the infant to ride in the front seat so that the driver
can constantly monitor the child’s condition.
Child age 1 to 12. A child age 1 to 12 must ride in the front seat because:
Vehicle has no rear seat:
Although children ages 1 to 12 ride in the rear seat(s) whenever possible,
children ages 1 to 12 sometimes must ride in the front because no space is
available in the rear seat(s) of vehicle; or
The child has a medical condition which, according to the child’s physician,
makes it necessary for the child to ride in the front seat so that the driver can
constantly monitor the child’s condition.
Medical condition. A passenger has a medical condition which according to his
or her physician:
Causes the passenger airbag to pose a special risk for the passenger: and
Makes the potential harm from the passenger airbag in a crash greater than the
potential harm from turning off the airbag and allowing the passenger, even if
belted, to hit the dashboard, or windshield in a crash.

2003 TUNDRA from Jul. ’03 Prod. (OM 34430U)
The SRS airbag system mainly consists 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 right front passenger (airbag and inflator)
4. Passenger airbag manual on −off switch
5. Airbag sensor assembly
6. Airbag module for driver (airbag and inflator)
The airbag sensor assembly consists of a
safing sensor and airbag sensor. The airbag sensors constantly monitor the
forward deceleration of the vehicle. If an
impact results in a forward deceleration
beyond the designed threshold level, the
system triggers the airbag inflators. At this
time a chemical reaction in the inflators
very quickly fills the airbags with non
−tox-
ic gas to help restrain the forward motion
of the occupants. The 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 physically and
safely exit the vehicle after a collision,
you should do so at the first opportunity. 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 r
educe 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 are 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.

reminder indicator to inform the driver of
operating problems. If either of the follow-
ing conditions occurs, this indicates a
malfunction of the airbags. Contact your
Toyota dealer as soon as possible to
service the vehicle.
The light does not come on when the
ignition key is turned to the “ON” posi-
tion, or the light remains on.
The light comes on or flashes while
driving.
In the following cases, contact your Toyota
dealer as soon as possible:
The SRS airbags have been inflated.
The front of the vehicle (shaded in the
illustration) was involved in an accident
that was not severe enough to cause
the SRS airbags to inflate.

Indicator light
This onoff switch is designed to dis-
able the passenger airbag in order to
allow usage, if necessary, of a member
of a passenger risk group identified in
TABLE 1 is occupying the right front
passenger seating position. (For details,
see “SRS driver airbag and front pas-
senger airbag” in this section.)
Operate onoff switch as follows:
Insert key into the keyhole and turn it.
To turn passenger airbag on: Turn the key
clockwise to the “ON” position.
To turn passenger airbag off: Turn the key
counterclockwise to the “OFF” position.
The indicator light comes on when the
passenger airbag system is off.
CAUTION
Make sure that the indicator light is
off.
Do not turn off the passenger air-
bag manual onoff switch except
when a member of a passenger risk
group identified in TABLE 1 (page
NO TAG) is occupying the right
front passenger seating position.
When the passenger airbag manual
onoff 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.
Toyota strongly urges the use of child
restraint systems for children small
enough to use them.
The laws of all 50 states in the U.S.A.
and Canada now require the use of a
child restraint system.
Your vehicle conforms to SAEJ1819.
If a child is too large for a child restraint
system, the child s hould sit in the seat
and must be restrained using the vehicle’s
seat belt. See “Seat belts” for details.
CAUTION
For effective protection in automo-
bile accidents and sudden stops, a
child must be properly restrained,
using a seat belt or child restraint
system depending on the age and
size of the child. Holding a child in
your arms is not a substitute for a
child restraint system. In an acci-
dent, the child can be crushed
against the windshield, or between
you and the vehicle’s interior.

STANDARD CAB MODELS—
Toyota strongly urges use of a
proper child restraint system which
conforms to the size of the child.
ACCESS CAB MODELS—
Toyota strongly urges use of a
proper child restraint system which
conforms to the size of the child,
installed on the rear seat. Accord-
ing to accident statistics, the child
is safer when properly restrained in
the rear seat than in the front seat.
Never put infant or child age 1 to
12 in a passenger risk group on the
right front seat with the passenger
airbag manual onoff switch in the
“ON” position. In the event of an
accident, the force of the rapid
inflation of the passenger airbag
can cause death or serious injury
to the child.
If you must put infant or child age
1 to 12 in a passenger risk group
on the right front seat, make sure
the passenger airbag manual onoff
switch is in the “OFF” position and
that the indicator light is on. (For
details, see “SRS driver airbag and
front passenger airbag” in this sec-
tion.)
Make sure that you have complied
with all installation instructions pro-
vided by the child restraint
manufacturer and that the system is
properly secured.A child restraint system for a small
child or baby must itself be properly
restrained on the seat with either the
lap belt or the lap portion of the lap/
shoulder belt. You must carefully con-
sult the manufacturer ’s instructions
which accompany the child restraint
system.
To provide proper restraint, use a child
restraint system following the manufactur-
er ’s instructions about the appropriate age
and size of the child for the child restraint
system.
Install the child restraint system correctly
following the instructions provided by its
manufacturer. General directions are also
provided under the following illustrations.
The child restraint system should be
installed on the rear seat if your vehicle
is equipped with rear seats. According to
accident statistics, the child is safer when
properly restrained in the rear seat than
in the front seat.

CAUTION
Never put infant or child age 1 to
12 in a passenger risk group on the
right front seat with the passenger
airbag manual onoff switch in the
“ON” position. In the event of an
accident, the force of the rapid
inflation of the passenger airbag
can cause death or serious injury
to the child.
If you must put infant or child age
1 to 12 in a passenger risk group
on the right front seat, make sure
the passenger airbag manual onoff
switch is in the “OFF” position and
that the indicator light is on. (For
details, see “SRS driver airbag and
front passenger airbag” in this sec-
tion.)
After installing the child restraint
system, make sure it is secured in
place according to the manufactur-
er’s instructions. If it is not re-
strained securely, it may cause
death or serious injury to the child
in the event of a sudden stop or
accident.
When not using the child restraint system,
keep it secured with the seat belt or place
it somewhere other than the passenger
compartment. This will prevent it from in-
juring passengers in the event of a sud-
den stop or accident. Child restraint systems are classified into
the following 3 types depending on the
child’s age and size.
(A) Infant seat
(B) Convertible seat
(C) Booster seat
Install the child restraint system following
the instructions provided by its manufac-
turer.
Your vehicle has anchor brackets for se-
curing the top strap of a child restraint
system.
For instructions on how to use the anchor
bracket, see “—Using a top strap” in this
section.
The child restraint lower anchorages ap-
proved for your vehicle may also be used.
See “—Installation with child restraint low-
er anchorages” in this section.

With the child restraint system installed,
check that your driving position is satis-
factory and that the child restraint system
does not interfere with your driving.
If your driving position is not satisfactory,
or the child restraint system interferes
with your driving, install it at another posi-
tion.
CAUTION
Ignoring the above instructions may
result in a serious injury in case of
an accident.
CAUTION
Never install a rearfacing child re-
straint system on the front seat with
the passenger airbag manual onoff
switch in the “ON” position. In the
event of an accident, the force of the
rapid inflation of the front passenger
airbag can cause death or serious in-
jury to the child.
When you put a rearfacing child re-
straint system on the front seat, turn
the passenger airbag manual onoff
switch counterclockwise to the “OFF”
position. (For details, see “SRS driver
airbag and front passenger airbag” in
this section.)
The indicator light comes on when the

CAUTION
If you must install a rearfacing child
restraint system on the front seat,
make sure the passenger airbag
manual onoff switch is in the “OFF”
position and that the indicator light is
on.
CAUTION
Do not install a child restraint sys-
tem on the rear seat if the child
restraint system interferes with the
front seat lock mechanism or with
your proper driving position. This
can cause death or serious injury
to the child and front passenger in
case of sudden braking or a colli-
sion.
If the driver ’s seat position does
not allow sufficient space for safe
installation, install the child re-
straint system on the rear right
seat.
