CAUTION
The SRS airbag system is designed
only as a supplement to the prima-
ry protection of the driver side and
right front passenger side seat belt
systems. The front seat occupants
can be killed or seriously injured by
the inflating airbags if they do not
wear the available seat belts prop-
erly. During sudden braking just be-
fore a collision, an unrestrained
driver or front passenger can move
forward 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.
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. As to access
cab models, Toyota recommends
that all infants and children be
placed in the rear seat of the ve-
hicle and properly restrained. The
rear seat is the safest for infants
and children. For instructions con-
cerning the installation of a child
restraint system, see “Child re-
straint” in this section.CAUTION
A member of a passenger risk group
should never sit or be occupied in
the right front passenger seat with
airbag manual onoff switch in the
“ON” position. (For details, see “SRS
driver airbag and front passenger air-
bag” in this section.)

CAUTION
Never install a rearfacing child re-
straint system on the right front
seat with the passenger airbag
manual onoff switch in the “ON”
position. In the event of an acci-
dent, the force of the rapid inflation
of the front passenger airbag can
cause death or serious injury to the
child.
A forwardfacing child restraint sys-
tem which belongs to a passenger
risk group should never be installed
on the right front seat with the pas-
senger airbag manual onoff switch
in the “ON” position, because the
force of the deploying airbag could
cause death or serious injury to the
child in forward seating position.
For instructions concerning the
installation of a child restraint sys-
tem, see “Child restraint” in this
section.
Do not sit on the edge of the seat
or lean over the dashboard when
the vehicle is in use, since the air-
bags inflate with considerable
speed and force. Otherwise, you
may be killed or seriously injured.
Sit up straight and well back in the
seat, and always use your seat belt
properly.

2003 TUNDRA from Jul. ’03 Prod. (OM 34430U)
Do not allow a child to stand up or
to kneel on the front passenger
seat, since the airbag inflates with
considerable speed and force.
Otherwise, the child may be killed
or seriously injured.
Do not hold a child on your lap or
in your arms. Use a child restraint
system in the rear seat. For instruc-
tions concerning the installation of
a child restraint system, see “Child
restraint” in this section.
Do not put objects or your pets 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 rear-
ward by the force of the deploying
airbags. Likewise, the driver and
front passenger should not hold ob-
jects 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 cause sud-
den SRS 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.

This SRS airbag system has a service
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.
The pad section of the steering wheel
or front passenger airbag cover
(shaded in the illustration) is scratched,
cracked, or otherwise damaged.
NOTICE
Do not disconnect the battery cables
before contacting your Toyota dealer.

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.

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
