2007 TOYOTA TUNDRA Owners Manual

882007 TUNDRA from Jul. ’07 Prod. (OM34463U)
Improperly seated and/or restrained
infants and children can be killed
or seriously injured by the
deploying 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
infants and children be placed in
the rear seat of the vehicle and
properly restrained. The rear seat is
the safest for infants and children.
For instructions concerning the
installation of a child restraint
system, see “Child restraint” on
page 114 in this Section.The SRS front airbags are designed to
deploy in severe (usually frontal) colli-
sions where the magnitude and duration
of the forward deceleration of the ve-
hicle exceeds the designed threshold
level.
The SRS front airbags will deploy if the
severity of the impact is above the de-
signed threshold level, comparable to an
approximate 25 km/h (15 mph) collision
when the vehicle has the impact straight
into a fixed barrier that does not move or
deform.
However, this threshold velocity will be
considerably higher if the vehicle strikes
an object, such as a parked vehicle or
sign pole, which can move or deform on
impact, or if the vehicle is involved in an
underride collision (e.g. a collision in
which the front of the vehicle “underrides”,
or goes under, the bed of a truck, etc.).
It is possible that in some collisions
where the forward deceleration of the ve-
hicle is very close to the designed thresh-
old level, the SRS front airbags and the
seat belt pretensioners may not activate
together.
Always wear your seat belts properly.

Collision from the
rearVehicle rollover
Collision from
the side
The SRS front airbags are not generally
designed to inflate if the vehicle is in-
volved in a side or rear collision, if it
rolls over, or if it is involved in a low
speed frontal collision. But, when ever a
collision of any type causes sufficient
forward deceleration of the vehicle, de-
ployment of the SRS front airbags may
occur.

The SRS front airbags may also deploy
if a serious impact occurs to the under-
side of your vehicle. Some examples
are shown in the illustration.
XS13104a
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. Passenger airbag on −off indicator light
3. Airbag module for front passenger (airbag and inflator)
4. Front passenger occupant classification ECU
5. Load sensor
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 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 front 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.

902007 TUNDRA from Jul. ’07 Prod. (OM34463U)
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 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.CAUTION
The driver or front passenger who is
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 passenger sit as far back
as possible from the dashboard.
All vehicle occupants be properly
restrained using the available seat
belts.
If the seat belt extender has been
connected to the driver ’s seat belt
buckle without the driver actually
wearing the seat belt, the SRS driv-
er ’s airbag system will judge that
the driver is wearing it. In this
case, the driver ’s airbag may not
activate correctly, causing death or
serious injury in the event of colli-
sion. Be sure to wear the seat belt
with the seat belt extender.
For instructions and precautions con-
cerning the seating position, see
“—Front seat precautions” on page
48 in this Section.

Do not sit on the edge of the seat
or lean against the dashboard when
the vehicle is in use, since the
front passenger airbag could inflate
with considerable speed and force.
Anyone who is up against, or very
close to, an airbag when it inflates,
can be killed or seriously injured.
Sit up straight and well back in the
seat, and always use your seat belt
properly.
XS13019
Toyota strongly recommends that all
infants and children be placed in
the rear seat of the vehicle and be
properly restrained.
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” on page 114 in this Sec-
tion.
XS13022b
Do not put anything or any part of
your body on or in front of the
dashboard or steering wheel pad
that houses the front airbag sys-
tem. They might restrict inflation or
cause death or serious injury as
they are projected rearward by the
force of the deploying airbags. Like-
wise, the driver and front passenger
should not hold objects in their
arms or on their knees.

922007 TUNDRA from Jul. ’07 Prod. (OM34463U)
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.
Do not modify or change the sus-
pension system. Such changes may
cause the driver airbag, front pas-
senger airbag, seat belt pretension-
ers and curtain shield airbags to
inflate accidentally, which could re-
sult in death or serious injury.
Do not use tires or wheels other
than the manufacturer ’s recom-
mended size. Such a use may cause
the driver airbag, front passenger
airbag, seat belt pretensioners and
curtain shield airbags to inflate ac-
cidentally, which could result in
death or serious injury. For details,
see “Checking and replacing tires”
on page 551 in Section 72.
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 a physical disability,
consult your Toyota dealer. It may
dangerously interfere with the SRS
front airbags operation.NOTICE
Do not perform any of the following
changes without consulting your
Toyota dealer. Such changes can
interfere 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

The SRS (Supplemental Restraint Sys-
tem) side airbags and curtain shield air-
bags are designed to provide further
protection for the driver and all win-
dowside passengers in addition to the
primary safety protection provided by
the seat belts.In response to a severe side impact, the
SRS side airbags and curtain shield air-
bags in the impacted side work with the
seat belts to help reduce injury by inflat-
ing. The SRS side airbags help reduce
injuries mainly to the driver’s or right front
passenger ’s chest. The SRS curtain shield
airbags help reduce injuries mainly to the
driver ’s and all window
−side passenger’s
head and help prevent them from being
thrown out of the vehicle.
The SRS side airbag on the passenger
seat will not activate if there is no pas-
senger sitting in the right front passenger
seat. However, the side airbag on the pas-
senger seat may deploy if luggage is put
in the seat. (As for the front passenger
occupant classification system, see
“—Front passenger occupant classification
system” on page 109 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.

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,
all window−side passenger ’s head and
help prevent them from being thrown out
of the vehicle. (This function can be
turned off if inflation is not desired. See
“—Roll sensing of curtain shield airbags
off switch” on page 113 in this Section.)
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, right
front passenger and rear outside
passenger seat belt systems. To en-
sure maximum protection in an ac-
cident, the driver and all passenger
in the vehicle must wear their seat
belts properly. Wearing a seat belt
properly during an accident reduces
the chances of death or serious in-
jury or being thrown out of the ve-
hicle. For instructions and precau-
tions concerning the seat belt sys-
tem, see “Seat belts” on page 65 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” on page
114 in this Section.
