2010 TOYOTA YARIS SEDAN tire pressure

306 5-2. Steps to take in an emergency
CAUTION
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute 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 illu mination 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 indi-
cator is combined with the low tire pressure telltale (tire pressure
warning light). When the system det ects a malfunction, the telltale will
flash for approximately one minute an d then remain continuously illumi-
nated. This sequence will continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the malfunction indi cator is illumi-
nated, 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 vari-
ety of reasons, including the installati on of replacement or alternate tires
or wheels on the vehicle that prevent the TPMS (tire pressure warning
system) from functioning properly. Always check the TPMS (tire pres-
sure warning system) malfunction te lltale after replacing one or more
tires or wheels on your vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPMS (tire pressure warning system) to
continue to function properly.
NOTICE
nPrecaution when installing a different tire
When a tire of a different specification or maker is installed, the tire pres-
sure warning system may not operate properly.

n
Compact spare tire
The compact spare tire saves space in your luggage compartment,
and its lighter weight helps to enhance fuel economy and permits
easier installation in case of a flat tire.
The compact spare tire is
designed for temporary emer-
gency use only.
The compact spare tire is identi-
fied by the distinctive wording
“TEMPORARY USE ONLY”
molded into the sidewall of the
tire.
nWhen using the compact spare tire
As the compact spare tire is not equipped with the tire pressure warning
valve and transmitter, low inflation pr essure of the compact spare tire will
not be warned. Also, if you replace the compact spare tire after the tire
pressure warning light comes on, the light remains on.
nCheck the tire inflation pressure of the compact spare tire.

nIf you have a flat front tire on a road covered with snow or ice
Install the compact spare tire on the rear of the vehicle. Perform the fol-
lowing steps and fit tire chains to the front tires.Replace a rear tire with the compact spare tire.
Replace the flat front tire with the tire removed from the rear of
the vehicle.
Fit tire chains to the front tires.
nAfter completing the tire change
The tire pressure warnin g system must be reset. ( →P. 247)

5-2. Steps to take in an emergency
NOTICE
nDo not drive the vehicle with a flat tire.
Do not continue driving with a flat tire.
Driving even a short distance with a flat tire can damage the tire and the
wheel beyond repair.
nBe careful when driving over bumps with the compact spare tire
installed on the vehicle.
The vehicle becomes lower when driving with the compact spare tire
compared to when drivin
g with standard tires. Be careful when driving
over uneven road surfaces.
nDriving with tire chains and the compact spare tire
Do not fit tire chains to the compact spare tire.
Tire chains may damage the vehicle body and adversely affect driving
performance.
nWhen replacing the tires
lWhen removing or fitting the wheels, tires or the tire pressure warning
valve and transmitter, contact your Toyota dealer as the tire pressure
warning valve and transmitter may be damaged if not handled cor-
rectly.
lReplace the grommets for the tire pressure warning valves and trans-
mitters as well.
nTo avoid damaging the tire pressure warning valves and transmit-
ters
Do not use liquid sealants on flat tires.

TUBELESS or TUBE TYPE
A tubeless tire does not have a tube and air is directly filled in the
tire. A tube type tire has a tube inside the tire and the tube main-
tains the air pressure.
