pant classification system.
LS13185
In the following cases, contact your Toyota
dealer as soon as possible:
The SRS front airbags have been in-
flated.
The front of the vehicle (shaded in the
illustration) was involved in an accident
that was not severe enough to cause
the SRS front airbags to inflate.
The pad section of the steering wheel
or front passenger airbag cover
(shaded in the illustration) is scratched,

The SRS side airbag and curtain shield
airbag system consists mainly of the fol-
lowing components, and their locations are
shown in the illustration.1. Curtain shield airbag modules (airbag and inflator)
2. Front passenger occupant classification ECU
3. Load sensor
4. Side airbag modules (airbag and inflator)
5. Curtain shield airbag sensors
6. Side and curtain shield airbag sensors
7. Front passenger ’s seat belt buckle switch 8. Front passenger occupant classification
indicator light
9. Airbag sensor assembly
10. SRS warning light The SRS side airbag and curtain shield
airbag system is controlled by the airbag
sensor assembly.
In a severe side impact, the side and
curtain shield airbag sensor and/or the
curtain shield airbag sensor trigger(s) the
side airbag inflators and/or the curtain
shield airbag inflators. At this time a
chemical reaction in the inflators quickly
fills the airbags with non −toxic gas to help
restrain the lateral motion of the occu-
pants.
When the airbags inflate, they produce a
fairly 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. Deployment of the airbags happens in a
fraction of a second, so the airbags must
inflate with considerable force. While the
system is desi
gned to reduce serious inju-
ries, it may also cause minor burns or
abrasions and swelling.
Front seats as well as parts of the front
and rear pillars, and roof side rail may be
hot for several minutes, but the airbags
themselves will not be hot. The airbags
are designed to inflate only once.
CAUTION
SRS side airbags and curtain shield
airbags inflate with considerable
force. To reduce the possibility of
death or serious injury when they in-
flate, the driver, front passenger and
rear outside passengers must:
Wear their seat belts properly.
Remain properly seated with their
backs upright and against the seats
at all times.
Improper sitting and wearing of the
seat belts may not retain you inside
the vehicle.

(m) Low Tire Pressure Warning Light
This light warns that the tire inflation pres-
sure of one or more of your tires (includ-
ing the spare tire) is low. The light comes
on when the ignition key is turned to the
“ON” position. It goes off after a few sec-
onds. This indicates that the low tire pres-
sure warning system is functioning proper-
ly.
If the light comes on, stop your vehicle in
a safe place as soon as possible and
check that the tire inflation pressure of all
tires (including the spare tire) is as
specified on the tire and loading
information label. (See “Checking tire
inflation pressure” on page 366 in Section
7 −2.) The light should go off a few
minutes after the tire pressure is adjusted. If the warning light blinks, the tire pres-
sure warning system may be malfunction-
ing. Contact your Toyota dealer.
For details, see “Tire pressure warning
system” on page 192 in Section 1
−7.
(n) Automatic Transmission Fluid Tem- perature Warning Light (fourwheel
drive models only)
This light warns that the automatic trans-
mission fluid temperature is too high.
If this light comes on while you are driv-
ing, slow down and pull off the road. Stop
the vehicle at a safe place and put the
selector lever in “P”. With the engine id-
ling, wait until the light goes off. If the
light goes off, you may start the vehicle
again. If the light does not go off, call a
Toyota dealer or qualified repair shop for
assistance.
NOTICE
Continued driving with the warning
light on may damage the automatic
transmission.

1942006 TACOMA from Jan.’06 Prod. (OM35871U)
NOTICE
Do not use liquid sealants for a flat
tire as air pressure sensors will be
damaged.
 When the tires must be repaired or
replaced, have them repaired or re-
placed by the nearest Toyota dealer
or authorized tire dealer. Failure to
do so may cause the tire pressure
sensors to be damaged when the
tires are removed or installed.
 The tire pressure warning system is
not to be used as a substitute for
regular inspections. Be sure to
check the air pressure in the tires
on a regular basis.
 When the air pressure sensors are
removed, check the grommets for
damage, and make sure that the
grommets are free from dirt, dust
and any other foreign matter. If air
leakage is found, replace the grom-
mets.
 Tire inflation pressure should be
adjusted for all tires (including the
spare tire).
Warning tends to turn on when
driving at lower outside tempera-
ture, such as in winter, because tire
inflation pressure will be decreased
due to the low temperature. In this
case, after adjustment and initializa-
tion, leave the ignition on for about
20 minutes and increase the tire
inflation pressure by 20 to 30 kPa.
If the warning light blinks:
The tire pressure warning system may
be malfunctioning. Contact your Toyota
dealer.
SYSTEM MALFUNCTION
The tire pressure warning system does
not function properly under certain cir-
cumstances. In the following cases, the
low tire pressure warning light may not
come on even if the tire inflation pres-
sure is low, or it may come on when
the tire inflation pressure is actually
normal.
Electric devices facilities using similar
radio wave frequencies are nearby.
A radio set to similar frequencies is in
use.
A lot of snow or ice covers the ve-
hicle, in particular, around the wheels
or wheel housings.
The tires are not equipped with an air
pressure sensor.
Snow tires or tire chains are used.
Non −genuine Toyota wheels are used.
The sensor battery is expired.
The system cannot receive radio waves
from the air pressure sensor on the
spare tire, depending on where the
sensor is located when the spare tire
is mounted on the vehicle.
In this case, rotate the spare tire by
about 90 ° so that the system can re-
ceive radio waves.

1952006 TACOMA from Jan.’06 Prod. (OM35871U)
NOTICE
The use of nongenuine wheels will
cause the air pressure sensors to
transmit the electronic code in dif-
ferent manner, resulting in the sys-
tem failure.
 The use of different type of tires
with genuine wheels may also
cause the malfunction of the sys-
tem.
LS17024
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 illuminates a low tire pressure
telltale (low tire pressure warning
light) when one or more of your tires
is significantly underinflated. Ac-
cordingly, when the low tire pressure
telltale (low tire pressure warning
light) illuminates, you should stop
and check your tires as soon as pos-
sible, and inflate them to the proper
pressure. Driving on a significantly
underinflated tire causes the tire to
overheat and can lead to tire failure.
Underinflation also reduces fuel effi-
ciency and tire tread life, and may
affect the vehicle’s handling and stop-
ping 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 responsib ility to
maintain correct tire pressure, even if
underinflation has not reached the
level to trigger illumination of the
TPMS low tire pressure telltale (low
tire pressure warning light).

1972006 TACOMA from Jan.’06 Prod. (OM35871U)
When replacing the wheels, be sure to
install air pressure sensors on the
wheels.
There are 3 ways to set up the air pres-
sure sensors:a. Remove the sensor from the old wheel and install it to the new wheel.
b. Keep the same wheel with air pressure sensor and replace only the tire.
c. Use a new wheel and sensor. In this case, you have to register an ID code
for a new sensor.
CAUTION
Initialization should be performed
with the tires adjusted at the speci-
fied tire inflation pressure. If they are
not adjusted properly, tire inflation
pressure to be warned will not be
appropriate. Initialization is completed
within a few minutes.
NOTICE
Have the tires, wheels or sensors
replaced and ID codes registered by
a Toyota dealer. If you need sen-
sors, purchase from a Toyota deal-
er.
 The sensor nuts should always be
tightened to a torque of 4 N·m (0.4
kgf·m, 2.9 ft·lbf).
 The use of nongenuine wheels will
cause the air pressure sensors to
transmit the electronic code in dif-
ferent manner, resulting in the sys-
tem failure.
 Remove the air pressure sensors
before replacing the tires to prevent
the sensors from being damaged.
