2008 TOYOTA 4RUNNER flat tire

199
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
under−inflated. 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 under−inflated tire causes
the tire to overheat and can lead to
tire failure. Under−inflation 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
under−inflation 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 start−ups 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 in ON" position, the
tire pressure warning system 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).
The system may be disabled in the follow-
ing conditions:
(When the condition becomes normal, the
system will work pr operly.)
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.

CAUTION
When doing the circling calibration,
be sure to secure a wide space,
and watch out for people and ve-
hicles in the neighborhood. Do not
violate any local traffic rules while
performing circling calibration.
Do not adjust the display while the
vehicle is moving. Be sure to adjust
the display only when the vehicle is
stopped.
The rear view monitor system assists
the driver by displaying an image of
the view behind the vehicle while back-
ing up. The image is displayed in re-
verse on the screen. This allows the
image to appear in the same manner as
that of the rear view mirror.
To display the rear view image on the
screen, place the selector lever in the
R" position when the engine switch is
in the ON" position.
If you move the selector lever out of the
R" position, the screen returns to the
previous screen. Operating another func-
tion of the navigation system will display
another screen.
The rear view monitor system is a supple-
ment device intended to assist back up.
When backing up, be sure to check be-
hind and all around the vehicle visually.CAUTION
Never depend on the rear view
monitor system entirely when back-
ing up. Always make sure your in-
tended path is clear.
Use caution, just as you would
when backing up any vehicle.
Never back up while looking only at
the screen. The image on the
screen is different from actual con-
ditions. Depicted distances between
objects and flat surfaces will differ
from actual distance. If you back up
while looking only at the screen,
you may hit a vehicle, a person or
an object. When backing up, be
sure to check behind and all around
the vehicle visually and with mir-
rors before proceeding.

7. TUBELESS" or TUBE
TYPE" A tubeless tire does not
have a tube inside the tire and air
is directly filled in the tire. A tube
type tire has a tube inside the tire
and the tube maintains the air
pressure.
8. Load limit at maximum cold tire inflation pressure For details,
see Checking and replacing tires"
on page 443.
9. Maximum cold tire inflation pressure This means the pres-
sure to which a tire may be in-
flated. For details about recom-
mended cold tire inflation
pressure, see Tires" on page 467.
10.Summer tire or all season tireAn all season tire has M+S"
on the sidewall. The tire not
marked with M+S" is a summer
tire. For details, see Types of
tires" on page 368.

DOT and Tire Identification
Number (TIN)

356 Temperature A, B, CT he temper a-
ture grades are A (the highest), B,
and C, representing the tire’s resis-
tance to the generation of heat and
its ability to dissipate heat when
tested under controlled conditions on
a specified indoor laboratory test
wheel. Sustained high temperature
can cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure. The grade C cor-
responds to a level of performance
which all passenger car tires must
meet under the Federal Motor Vehicle
Safety Standard No.109. Grades B
and A represent higher levels of per-
formance on the laboratory test wheel
than the minimum required by law.
Warning: The temperature grades for
this tire are established for a tire that
is properly inflated and not over-
loaded. Excessive speed, underinfla-
tion, or excessive loading, either sep-
arately or in combination, can cause
heat buildup and possible tire failure.
