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.

If the light is flashing, we recommend that
you replace the engine oil at an early
opportunity depending on the driving and
road conditions. If the light comes on,
replace it as soon as possible.
The system must be reset after the
engine oil replacement. Reset the system
by the following procedure:1. Turn the ignition switch to the “OFF” position with the trip meter A reading
shown. (For details, see “Odometer and
two trip meters” on page 186 in this
Section.)
2. Turn the ignition switch to the “ON” position while holding down the trip
meter reset knob.
Hold down the knob for at least 5
seconds. The trip meter A indicates
“000000” and the light goes off.
If the system fails to reset, the light will
continue flashing.
(h) Low Fuel Level Warning Light
This light comes on when the fuel level
in the tank becomes nearly empty. Fill up
the tank as soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the low fuel level
warning light may come on earlier than
usual. (i) “ABS” Warning Light
The light comes on when the ignition
switch is turned to the “ON” position. If
the anti
−lock brake system and the brake
assist system work properly, the light
turns off after a few seconds. Thereafter,
if either of the systems malfunctions, the
light comes on again.
When the “ABS” warning light is on (and
the brake system warning light is off), the
following systems do not operate, but the
brake system still operates conventionally.
Anti −lock brake system
Brake assist system
Traction control system
“AUTO LSD” system
Vehicle stability control system
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti −lock brake system does not operate,
so that the wheels will lock up during a
sudden braking or braking on slippery
road surfaces.
If either of the following conditions oc-
curs, this indicates a malfunction some-
where in the components monitored by
the warning light system. Contact your
Toyota dealer as soon as possible to
service the vehicle.
The light does not come on when the
ignition switch is turned to the “ON”
position, or remains on.
The light comes on while you are dri-
ving.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If the “ABS” warning light remains on
together with the brake system warn-
ing light, immediately stop your ve-
hicle at a safe place and contact your
Toyota dealer.
In this case, not only the antilock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.

(j) “VSC OFF” warning light
The light flashing warns that there is a
problem somewhere in the following.
Vehicle stability control system
Traction control system
“AUTO LSD” system
The light will come on when the ignition
switch is turned to the “ON” position, and
will go off after a few seconds.
If the light flashes on while driving, the
above mentioned systems do not work.
However, as conventional braking operates
when applied, there is no problem to con-
tinue your driving.
In the following cases, contact your Toyota
dealer:
The warning light does not come on
after the ignition switch is turned to the
“ON” position.
The warning light remains on after the
ignition switch is turned to the “ON”
position.
The warning light flashes while driving. (k) Open Door Warning Light
This light remains on until all the doors
are completely closed.
The buzzer also sounds once when any
of the doors is not completely closed at
the vehicle speed 5 km/h (3 mph) or
more. Stop the vehicle and close all the
door completely.
(l) SRS Warning Light
This light will come on when the igni-
tion switch is turned to the “ON” posi-
tion. After about 6 seconds, the light
will go off. This means the systems of
the airbag and front seat belt preten-
sioners are operating properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sen-
sors, curtain shield airbag sensors, driv-
er ’s seat position sensor, driver ’s seat belt
buckle switch, front passenger occupant
classification system
∗, passenger airbag
off switch, passenger airbag on −off indica-
tor light, seat belt pretensioner assem-
blies, inflators, “RSCA OFF” indicator light,
interconnecting wiring and power sources.
∗: The front passenger occupant classifica-
tion system includes the front passenger
occupant classification ECU, load sensor
and front passenger ’s seat belt buckle
switch.
If either of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Toyota dealer as
soon as possible to service the vehicle.
The light does not come on when the
ignition switch is turned to the “ON”
position or remains on for more than
6 seconds.
The light comes on while driving.
(m) Tire Pressure Warning Light
This light warns that the tire inflation pres-
sure of one or more of your tires (except
for the temporary spare tire) is low. The
light comes on when the ignition switch is
turned to the “ON” position. It goes off
after a few seconds. This indicates that
the tire pressure warning system is func-
tioning properly.

2532007 TUNDRA from Jul. ’07 Prod. (OM34463U)
CAUTION
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the vehicle placard
or tire inflation pressure label (tire
and load information label). (If your
vehicle has tires of a different size
than the size indicated on the vehicle
placard or tire inflation pressure label
(tire and load information label), you
should determine the proper tire infla-
tion pressure for those tires.)
As an added safety feature, your ve-
hicle has been equipped with a tire
pressure monitoring system (TPMS
tire pressure warning system) that il-
luminates a low tire pressure telltale
(tire pressure warning light) when one
or more of your tires is significantly
underinflated. Accordingly, when the
low tire pressure telltale (tire pres-
sure warning light) illuminates, you
should stop and check your tires as
soon as possible, and inflate them to
the proper pressure. Driving on a sig-
nificantly underinflated tire causes
the tire to overheat and can lead to
tire failure. Underinflation also re-
duces fuel efficiency and tire tread
life, and may affect the vehicle’s han-
dling and stopping ability.
Please note that the TPMS (tire pres-
sure warning system) is not a substi-
tute for proper tire maintenance, and
it is the driver ’s responsibility to
maintain correct tire pressure, even if
underinflation has not reached the
level to trigger illumination of the
TPMS low tire pressure telltale (tire
pressure warning light).Your vehicle has also been equipped
with a TPMS (tire pressure warning
system) malfunction indicator to indi-
cate when the system is not operat-
ing properly. The TPMS (tire pressure
warning system) malfunction indicator
is combined with the low tire pres-
sure telltale (tire pressure warning
light). When the system detects a
malfunction, the telltale will flash for
approximately one minute and then
remain continuously illuminated. This
sequence will continue upon subse-
quent vehicle startups as long as
the malfunction exists. When the mal-
function indicator is illuminated, the
system may not be able to detect or
signal low tire pressure as intended.
