TPMS TOYOTA TACOMA 2008 Owners Manual (in English)

2008 TACOMA from Apr. ’08 Prod. (OM35898U)
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.

TPMS (tire pressure warning system)
malfunctions may occur for a variety
of reasons, including the installation
of replacement or alternate tires or
wheels on the vehicle that prevent
the TPMS (tire pressure warning sys-
tem) from functioning properly. Al-
ways check the TPMS (tire pressure
warning system) malfunction telltale
after replacing one or more tires or
wheels on your vehicle to ensure that
the replacement or alternate tires and
wheels allow the TPMS (tire pressure
warning system) to continue to func-
tion properly.
NOTICE
Do not use liquid sealants for a flat
tire as tire pressure warning valve
and transmitter will be damaged.
 When the tires must be repaired or
replaced, have them repaired or re-
placed by the nearest Toyota dealer
or an authorized tire dealer. The
tire pressure warning valves and
transmitters will be affected by the
installation or removal of tires.

IF THE TIRE PRESSURE WARNING
LIGHT COMES ON AFTER BLINKING
FOR 1 MINUTE...
If the tire pressure warning light comes
on after blinking for 1 minute when the
engine switch is turned to the “ON”
position, the tire pressure warning sys-
tem is not working properly.
The system will be disabled in the follow-
ing conditions:
(When the condition becomes normal, the
system will work properly.)
If tires not equipped with tire pressure
warning valves and transmitters are
used.
If the ID code on the tire pressure
warning valves and transmitters is not
registered in the tire pressure warning
computer.
If the tire inflation pressure is more
than 500 kPa (5.1 kgf/cm2
or bar, 73
psi) or higher than the specified level.
The system may be disabled in the follow-
ing conditions:
(When the condition becomes normal, the
system will work properly.)
If electronic devices or facilities using
similar radio wave frequencies are
nearby.
If a radio set at similar frequencies is
in use in the vehicle.
If a window tint that affects the radio
wave signals is installed.
If there is a lot of snow or ice on the
vehicle, in particular around the wheels
or wheel housings.
If non −genuine Toyota wheels are used.
If tire chains are used.
If the spare tire is in a location subject
to poor radio wave signal reception.
If a large metallic object which can
interfere with signal reception is put in
the deck.
