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 vehicle 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 inflation pressure label, you should deter-
mine the proper tire inflation 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 under-
inflated. Accordingly, when the low tire pressure telltale illuminates,
you should stop and check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a significantly under-inflated
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 and stopping ability.
Please note that the TPMS is not a substitute for proper tire mainte-
nance, and it is the driver’s responsibility to maintain correct tire pres-
sure, even if under-inflation has not reached the level to trigger
illumination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indica-
tor to indicate when the system is not operating properly.
The TPMS malfunction indicator is combined with the low tire pressure
telltale. When the system detects a malfunction, the telltale will flash
for approximately one minute and then remain continuously illumi-
nated. This sequence will continue upon subsequent vehicle start-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 properly.
Always check the TPMS 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 to continue to function prop-
erly.
●To avoid false readings, the system samples for a little while before
indicating a problem. As a result it will not instantaneously register a
rapid tire deflation or blow out.

5-3. Owner Maintenance
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 specification charts
(→P. 5 7 0).
Vehicles with tire pressure monitoring system:
After adjusting the tire pressure, initialization of the tire pressure mon-
itoring system is necessary to make the system operate normally.
Refer to Tire Pressure Monitoring System Initialization on P. 221.
●Always check tire pressure when tires are cold.
●Warm tires normally exceed recommended pressures. Do not release
air from warm tires to adjust the pressure.
●Underinflation can cause reduced fuel economy, uneven and acceler-
ated tire wear, and poor sealing of the tire bead, which will deform the
wheel and cause separation of tire from rim.
●Overinflation can produce a harsh ride, uneven and accelerated tire
wear, and a greater possibility of damage from road hazards.
For reasons of proper performance, 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 different types of tires is dangerous. It could
cause poor handling and poor braking; leading to loss of control.
Except for the limited use of the temporary spare tire, use only the same
type tires (radial, bias-belted, bias-type) on all four wheels.
■Using Wrong-Sized Tires
Using any other tire size than what is specified for the vehicle ( →P. 570)
is dangerous. It could seriously affect ride, handling, ground clearance,
tire clearance, and speedometer calibration. This could cause you to
have an accident. Use only tires that are the correct size specified for
the vehicle.

Maintenance and Care
Keep your tire pressure at the correct levels. If one frequently needs
inflating, have it inspected.
During rotation, inspect them for
correct balance.
Also, inspect them for uneven wear and damage. Abnormal wear is
usually caused by one or a combination of the following:
●Incorrect tire pressure
● Improper wheel alignment
● Out-of-balance wheel
● Severe braking
After rotation, inflate all tire pressures to specification (
→P. 570) and
inspect the lug nuts for tightness.
Vehicles with tire pressure monitoring system:
After adjusting the tire pressure, initialization of the tire pressure mon-
itoring system is necessary to make the system operate normally.
WARNING
■Always inflate the tires to the correct pressure
Overinflation or underinflation of tires is dangerous. Adverse handling or
unexpected tire failure could result in a serious accident.
Refer to Tires on ( →P. 570).
■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 decrease which
could result in a serious accident. Do not use any part for the tire valve
cap that is not a Toyota-genuine part.
Tire Rotation
Forward
Do not include (TEMPORARY
USE ONLY) spare tire in rotation.

Tire Pressure Monitoring
System Warning Light
When the warning light illu-
minates, and the warning
beep sound is heard (about
3 seconds), tire pressure is
too low in one or more tires.
Inspect the tires and
adjust to the specified
inflation pressure
(→ P. 446).
• Perform tire pressure adjustment when the
tires are cold. Tire
pressure will vary
according to the tire
temperature, there-
fore let the vehicle
stand for 1 hour or
only drive it 1 mile
(1.6 km) or less
before adjusting the
tire pressures. When
pressure is adjusted
on hot tires to the
cold inflation pres-
sure, the TPMS
warning light/beep
may turn on after the
tires cool and pres-
sure drops below
specification.

5246-7. Warning/Indicator Lights and Warning Sounds
YARIS_SEDAN_OM_OM99M18z_(U)
If the driver’s door is opened while the ignition is switched to ACC, a
continuous beep sound will be heard to notify the driver that the igni-
tion has not been switched off (STOP). Left in this condition, the key-
less entry system will not operate, the car cannot be locked, and the
battery power will be depleted.
A beep sound will be heard 6 times and the KEY warning light (red)
will flash continuously if the ignition has not been switched off, all the
doors are closed, and the key is removed from the vehicle. This is to
notify the driver that the key has been removed from the vehicle and
the ignition has not been switched off.
Because the key utilizes low-intensity radio waves, the Key Removed From
Vehicle Warning may activate if the key is carried together with a metal object
or it is placed in a poor signal reception area.
The warning beep sound will be heard for about 3 seconds when
there is any abnormality in tire inflation pressures (→P. 218).
If there is the possibility of a collision with a vehicle ahead, the beep
sounds continuously and a warning is indicated in the display.
If the power steering system has a malfunction, the power steering
malfunction light turns on or flashes and the buzzer operates at the
same time.
Refer to Warning/Indicator Lights on P. 156.

7-7. Tire Information (U.S.A.)
■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 amount 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 wet
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 resistance to the generation of heat and
its ability to dissipate heat when tested under controlled condi-
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 should only
be used in pairs or placed on all four wheels. Make sure you pur-
chase snow tires that are the same size and construction type as
the other tires on your vehicle.
■SAFETY WARNING
The following safety warning appears on the tire’s sidewall. SERI-
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 UNDER-INFLATION/OVERLOADING/ DAMAGE- FOLLOW OWNER’S MANUAL AND PLACARD IN
VEHICLE-FREQUENTLY CHECK INFLATION PRESSURE AND
INSPECT FOR DAMAGE.

Customer Information and Reporting Safety Defects
Location of the Tire Label (Placard)
You will find the tire label containing tire inflation pressure by tire size
and other important information on the driver’s side B-pillar or on the
edge of the driver’s door frame.
SAMPLE
On the tire label you will find the recommended tire inflation pressure
in both kPa and psi for the tires installed as original equipment on the
vehicle. It is very important that the inflation pressure of the tires on
your vehicle is maintained at the recommended pressure. You should
check the tire pressure regularly to insure that the proper inflation
pressure is maintained.
Refer to Tires on P. 570.
Tire pressures listed on the vehicle placard or tire information label indi-
cate the recommended cold tire inflation pressure, measured when 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.
