2006 TOYOTA TACOMA sensor

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.

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).

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.

The outside temperature display indi-
cates the outside air temperature. The
displayed value is updated.
To set the unit, push the “E/M” button
until the desired unit display appears.
The displayed temperature ranges from
−30 C ( −22 F) up to 50 C (122 F).
If an abnormality exists in the connection
of the outside air temperature sensor,
“ −− C” (“ −−F”) will appear on the display.
If “ −−C” (“ −−F”) appears on the display,
contact your Toyota dealer.
There may be a case that “−− C” (“ −−F”)
appears momentarily when the ignition is
quickly turned to “ON”. It is normal if it
goes out soon.
—Compass
LS10036
The compass indicates the direction
that the vehicle is heading. In the
above case, it shows that the vehicle is
heading west.
The direction display is updated every 2
seconds.

The compass may not show the correct
direction in the following conditions:
The vehicle is stopped immediately af-
ter turning.
The compass does not adjust while the
vehicle is stopped.
The ignition switch is turned off imme-
diately after turning.
The vehicle is on an inclined surface.
The vehicle is in a place where the
earth’s magnetic field is subject to in-
terference by artificial magnetic fields
(underground parking, under a steel
tower, between buildings, roof parking,
near a crossing, near a large vehicle,
etc.).
The vehicle is magnetized. (There is a
magnet or a metal object on or near
the roof.)
The battery has been disconnected.
If the deviation is small, the compass
works to calibrate the direction automati-
cally while the vehicle is in motion.

The compass sensor is on the roof of
the vehicle.
NOTICE
Do not put magnets or a metal object
on or near the roof of the vehicle.
Doing this may cause malfunction of
the compass sensor.
CALIBRATING THE COMPASS (deviation
calibration)
The direction display on the compass
deviates from the true direction deter-
mined by the earth’s magnetic field. The
angle of deviation varies according to the
geographic position of the vehicle.
To adjust this deviation, stop the vehicle,
then push and hold the “E/M” button until
the “VAR” indication appears on the com-
pass display. Then push the “E/M” button,
referring to the following map to select the
number of the zone where the vehicle is.

Driving with tire chains installed.
Driving over the steps such as the
joints on the road.
Driving on roads where the road
surface is pitted or has other differ-
ences in surface height.
Install all 4 tires of specified size at
appropriate pressure: The antilock
brake system detects vehicle speeds
using the speed sensors for respec-
tive wheels’ turning speeds. The use
of tires other than specified may fail
to detect the accurate turning speed
resulting in a longer stopping dis-
tance.

“ABS” warning light (without the
vehicle stability control system)
The light comes on when the ignition key
is turned to the “ON” position. If the anti −
lock brake system works properly, the
light turns off after a few seconds. There-
after, if the system malfunctions, the light
comes on again.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti −lock brake system does not operate,
but the brake system still operates con-
ventionally.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti −lock brake system does not operate
but the brake assist system still operates.
In this case the wheels could lock up
during a sudden braking or braking on
slippery road surfaces.
If either of the following conditions
occurs, this indicates a malfunction
somewhere in the components moni-
tored by the warning light system. Con-
tact 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 tire pressure warning system
must be initialized when the
specified tire inflation pressure is
changed due to tire replacement.
See “Tire pressure warning
system” on page 192 in Section
17.NOTICE
When the tires must be re-
paired or replaced, have them
repaired or replaced by the
nearest Toyota dealer or au-
thorized tire dealer. Failure to
do so may cause the tire
pressure sensors to be dam-
aged when the tires are re-
moved or installed.
 Remove the air pressure sen-
sors before replacing the
tires to prevent the sensors
from being damaged.

When installing aluminum wheels,
check that the wheel nuts are tight
after driving your vehicle the first 1600
km (1000 miles).
If you have rotated, repaired, or
changed your tires, check that the
wheel nuts are still tight after driving
1600 km (1000 miles).
When using tire chains, be careful not
to damage the aluminum wheels.
Use only Toyota wheel nuts and
wrench designed for your aluminum
wheels.
When balancing your wheels, use only
Toyota balance weights or equivalent
and a plastic or rubber hammer.
As with any wheel, periodically check
your aluminum wheels for damage. If
damaged, replace immediately.
