While the vehicle is being driven, all ve-
hicle occupants should have the seatback
upright, sit well back in the seat and prop-
erly wear the seat belts provided.
CAUTION
Do not drive the vehicle unless the
occupants are properly seated. Do
not allow passengers to sit on top
of a foldeddown seatback, or in
the luggage compartment or cargo
area. Persons not properly seated
and/or properly restrained by seat
belts can be severely injured in the
event of emergency braking or a
collision.
During driving, do not allow pas-
sengers to stand up or move
around between seats. Otherwise,
severe injuries can occur in the
event of emergency braking or a
collision.
Driver seat
CAUTION
The SRS driver airbag deploys with
considerable force, and can cause
death or serious injury especially if
the driver is very close to the airbag.
The National Highway Traffic Safety
Administration (“NHTSA”) advises:
Since the risk zone for driver airbag
is the first 50—75 mm (2—3 in.) of
inflation, placing yourself 250 mm (10
in.) from your driver airbag provides
you with a clear margin of safety.
This distance is measured from the
center of the steering wheel to your
breastbone. If you sit less than 250
mm (10 in.) away now, you can
change your driving position in sever-
al ways:
Move your seat to the rear as far
as you can while still reaching the
pedals comfortably.
Slightly recline the back of the
seat. Although vehicle designs vary,
many drivers can achieve the 250
mm (10 in.) distance, even with the
driver seat all the way forward, sim-
ply by reclining the back of the
seat somewhat. If reclining the back
of your seat makes it hard to see
the road, raise yourself by using a
firm, nonslippery cushion, or raise
the seat if your vehicle has that
feature.
If your steering wheel is adjustable,
tilt it downward. This points the air-
bag toward your chest instead of
your head and neck.
The seat should be adjusted as rec-
ommended by NHTSA above, while
still maintaining control of the foot
pedals, steering wheel, and your view
of the instrument panel controls.

In the following cases, contact your Toyota
dealer as soon as possible:
The front of the vehicle (shaded in the
illustration) was involved in an acci dent
that was not severe enough to cause
the front seat belt pretensioners to op-
erate.
Either front seat belt pretensioner as-
sembly or surrounding area is
scratched, cracked, or otherwise dam-
aged.
The SRS (Supplemental Restraint Sys-
tem) airbags are designed to provide
further protection for the driver and
right front passenger in addition to the
primary safety protection provided by
the seat belts.
Vehicles with separate front seats—The
SRS airbags are designed to protect
the driver and front passenger.
Vehicles with bench type front seats—
The SRS airbags are designed to pro-
tect the driver and right −front passen-
ger. They are not designed to protect
occupant in the center position. In response to a severe frontal impact,
the SRS airbags work together with the
seat belts to help reduce injury by inflat-
ing. The SRS airbags help to reduce inju-
ries mainly to the driver’s or right front
passenger ’s head or chest caused by di-
rectly hitting the steering wheel or dash-
board. The front passenger airbag is acti-
vated even with no passenger in the front
seat.
Be sure to wear your seat belt properly.
Your vehicle is equipped with a crash
sensing and diagnostic module, which will
record the use of the seat belt restraint
system by the driver and right front pas-
senger when the SRS airbags are inflated.

CAUTION
The driver or front passengers who
are too close to the steering wheel or
dashboard during airbag deployment
can be killed or seriously injured.
Toyota strongly recommends that:
The driver sit as far back as pos-
sible from the steering wheel while
still maintaining control of the ve-
hicle.
The front passengers sit as far
back as possible from the dash-
board.
All vehicle occupants be properly
restrained using the available seat
belts.
Indicator light
The passenger airbag system is
equipped with a manual onoff switch
and indicator light. Turning the passen-
ger airbag manual onoff switch clock-
wise to the “ON” position makes the
passenger airbag system operational.
Turning the passenger airbag manual
onoff switch counterclockwise to the
“OFF” position disables the passenger
airbag system. The indicator light on
the passenger airbag manual onoff
switch will come on when the passen-
ger airbag system has been disabled.
See “Passenger airbag manual on −off
switch” in this section for detail.
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 is oc-
cupying 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.

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.

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.

CAUTION
Do not adjust the steering wheel
while the vehicle is moving. Doing
so may cause the driver to mishan-
dle the vehicle and an accident may
occur resulting in death or serious
injuries.
After adjusting the steering wheel,
try moving it up and down to make
sure it is locked in position.
Adjust the mirror so that you can just
see the side of your vehicle in the mir-
ror.
Be careful when judging the size or dis-
tance of any object seen in the outside
rear view mirror on the passenger’s side
because it is a convex mirror. Any object
seen in a convex mirror will look smaller
and farther away than when seen in a flat
mirror.
CAUTION
Do not adjust the mirror while the
vehicle is moving. Doing so may
cause the driver to mishandle the
vehicle and an accident may occur
resulting in death or serious inju-
ries.
On some models, since the mirror
surfaces can get hot, do not touch
them when the outside rear view
mirror heater switch is on.
