3-12. Tire Pressure Monitoring System
NOTICE
●Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehi cle placard or tire inflation pressure
label. (If your vehicle has tires of a different size than the size indicated
on the vehicle placard or tire i nflation pressure label, you sh ould deter-
mine the proper tire inflati on pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS ) that illuminates a low tire pres-
sure telltale when one or more of your tires is significantly u nder-
inflated. Accordingly, when the low tire pressure telltale illuminates,
you should stop and check your tires as soon as possible, and i nflate
them to the proper pressure. Driving on a significantly under-i nflated
tire causes the tire to overheat and can lead to tire failure. Under-infla-
tion also reduces fuel efficiency and tire tread life, and may affect the
vehicle’s handling an d stopping ability.
Please note that the TPMS is not a substitute for proper tire m ainte-
nance, and it is the driver’s r esponsibility to maintain correc t tire pres-
sure, even if under-inflation has not reached the level to trig ger
illumination of the TPMS lo w tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction ind ica-
tor to indicate when the syste m is not operating properly.
The TPMS malfunction indicator i s combined with the low tire pressure
telltale. When the system detects a malfunction, the telltale will flash
for approximately one minute an d then remain continuously illumi-
nated. This sequence will contin ue upon subsequent vehicle star t-ups
as long as the malfunction exists . When the malfunction indicator is
illuminated, the system may not be able to detect or signal low tire
pressure as intended. TPMS 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 from functioning pr operly.
Always check the TPMS malfunction telltale after replacing one or
more tires or wheels on your veh icle to ensure that the replacement or
alternate tires and wheels allow the TPMS to continue to functi on prop-
erly.
●To avoid false readings, the system samples for a little while before
indicating a problem. As a res ult it will not instantaneously register a
rapid tire deflation or blow out.

Maintenance and Care
Tires
Inspect all tire pressures monthly (including the spare) when the tires
are cold. Maintain recommended pressures for the best ride, han -
dling, and minimum tire wear.
Refer to the spec ification charts
(P. 5 8 2).
With tire pressure m onitoring system:
After adjusting the tire pressur e, initialization of the tire p ressure mon-
itoring system is necessary to m ake the system operate normally .
Refer to Tire Pressure Monitorin g System Initialization on P. 233.
For reasons of proper performan ce, safety, and better fuel econ-
omy, always maintain recommended tire inflation pressures and
stay within the recommended load limits and weight distribu-
tion.
WARNING
■Using Different Tire Types
Driving your vehicle with differ ent types of tires is dangerous . It could
cause poor handling and poor bra king; leading to loss of control.
Except for the limited use of the temporary spare tire, use onl y the same
type tires (radial, bi as-belted, bias-type) on all four wheels.
■Using Wrong-Sized Tires
Using any other tire size than wh at is specified for the vehicle (P. 5 8 2 )
is dangerous. It could seriously affect ride, handling, ground clearance,
tire clearance, and speedometer calibration. This could cause y ou to
have an accident. Use only tires that are the correct size spec ified for
the vehicle.

4605-3. Owner Maintenance
YARIS SEDAN_OM_OM99S50z_(U)
●Always check tire pressure when tires are cold.
●Warm tires normally exceed recommended pressures. Do not releas e
air from warm tires to adjust the pressure.
●Underinflation can cause reduced fuel economy, uneven and accel er-
ated tire wear, and poo r sealing of the tire bead, which will d eform the
wheel and cause separat ion of tire from rim.
●Overinflation can produce a harsh ride, uneven and accelerated tire
wear, and a greater p ossibility of damage from road hazards.
Keep your tire pressure at the correct levels. If one frequentl y needs
inflating, have it inspected.
During rotation, inspect them for
correct balance.
WARNING
■Always inflate the tires to the correct pressure
Overinflation or underinflation o f tires is dangerous. Adverse handling or
unexpected tire failure could result in a serious accident.
Refer to Tires on ( P. 582).
■Use only a Toyota-genuine tire valve cap
Use of a non-genuine part is dangerous as the correct tire air pressure
cannot be maintained if the tire valve becomes damaged. If the vehicle
is driven under this condition, the tire air pressure will decr ease which
could result in a serious accident. Do not use any part for the tire valve
cap that is not a Toyota-genuine part.

Customer Information and Reporting Safety Defects
■Maximum Load Rating
This number indicates the maximum load in kilograms and pounds
that can be carried by the tire.
■Maximum Permissible Inflation Pressure
This number is the greatest amoun t of air pressure that should ever
be put in the tire under normal driving conditions.
■Tread Wear, Traction and Temperature Grades
●Tread wear: The tread wear grade is a comparative rating based
on the wear rate of the tire when tested under controlled condi -
tions on a specified government test course. For example, a tire
graded 150 would wear one and one-half (1 1/2) times as well on
the government course as a tire graded 100.
● Traction: The traction grades, from highest to lowest are AA, A ,
B, and C. The grades represent the tire’s ability to stop on we t
pavement as measured under controlled conditions on specified
government test surfaces of asphalt and concrete. A tire marked
C may have poor traction performance.
● Temperature: The temperature grades are A (the highest), B and
C, representing the tire’s res istance to the generation of heat and
its ability to dissipate heat w hen tested under controlled cond i-
tions on a specified indoor laboratory test wheel.
■Snow Tires
In some heavy snow areas, local governments may require true
snow tires, those with very deeply cut tread. These tires shoul d only
be used in pairs or placed on all four wheels. Make sure you pu r-
chase snow tires that are the sa me size and construction type as
the other tires on your vehicle.
■SAFETY WARNING
The following safety warning appears on the tire’s sidewall. SE RI-
OUS INJURY MAY RESULT FROM: • EXPLOSION OF TIRE/RIM ASSEMBLY DUE TO IMPROPER MOUNTING-MATCH TIRE DIAMETER TO RIM DIAMETER;
NEVER EXCEED 40 psi (275 kPa) TO SEAT BEADS-ONLY
SPECIALLY TRAINED PERSONS SHOULD MOUNT TIRES.
• TIRE FAILURE DUE TO UNDE R-INFLATION/OVERLOADING/

Location of the Tire Label (Placard)
You will find the tire label containing tire inflation pressure by tire size
and other important i nformation on the driver’s side B-pillar o r on the
edge of the driver’s door frame.
SAMPLE
On the tire label you will find t he recommended tire inflation pressure
in both kPa and psi for the tire s installed as original equipment on the
vehicle. It is very important that the inflation pressure of th e tires on
your vehicle is maintained at t he recommended pressure. You sho uld
check the tire pressure regularly to insure that the proper inf lation
pressure is maintained. Refer to Tires on P. 582.
Tire pressures listed on the vehicle placard or tire informatio n label indi-
cate the recommended cold tire inflation pressure, measured whe n the
tires are cold, after the vehicle has been parked for at least 3 hours. As
you drive, the temperature in the tire warms up, increasing the tire pres-
sure.
