NOTICE
If the system initialization is performed without adjusting the tire pres-
sure, the system cannot detect th e normal tire pressure and it may not
illuminate the tire pre ssure monitoring system warning light ev en if a tire
pressure is low, or it may illuminate the light even if the pre ssures are
normal.
Adjust the tire pressure on all four tires and initialize the s ystem when
the warning light is turned on. If the warning light turns on f or a reason
other than a flat tire, the tire pressure of all four tires may have
decreased naturally.
The system initialization will not be performed if the switch i s pressed
while the vehicle is being driven.

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 5 3).
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. 244.
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 5 3 )
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.
Tire Inflation Pressure
4145-3. Owner Maintenance
YARIS_YARIS HATCHBACK_OM_OM99V59z_(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. 553).
■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.
Tire Rotation

Do not include
(TEMPORARY USE ONLY)
spare tire in rotation.

Maintenance and Care
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. 553) and
inspect the lug nu ts for tightness.
With tire pressure monitoring 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. 244.
WARNING
■Rotate tires periodically
Irregular tire wear is dangerous. To equalize tire wear and ext end tire
life, Toyota recommends that tire rotation is carried out at th e same
interval as tire inspection.
For scheduled maintenance information, please refer to the “Own er’s
Manual Supplement/Schedul ed Maintenance Guide”.
NOTICE
Rotate unidirectional tires and radial tires that have an asymm etrical
tread pattern or studs only from front to rear, not from side t o side. Tire
performance will be redu ced if rotated from side to side.
4165-3. Owner Maintenance
YARIS_YARIS HATCHBACK_OM_OM99V59z_(U)
If a tire wears evenly, a wear indicator will appear as a solid band
across the tread.
Replace the tire when this happens.New tread

You should replace the tire bef ore the band crosses the entire tread.
With tire pressure monitoring 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. 244.
Tires degrade over time, even wh en they are not being used on the road.
It is recommended that tires gen erally be replaced when they are 6 years
or older. Heat caused by hot climates or frequent high loading conditions
can accelerate the aging process. You should replace the spare tire when
you replace the other road tires due to the aging of the spare tire. The
period in which the tire was manufactured (both week and year) is indi-
cated by a 4-digit number.
Refer to Tire Labeling on P. 522.

WARNING
■Always use tires that are in good condition
Driving with worn tires is dangero us. Reduced braking, steering, and
traction could result in an accident.
■Replace all four tires at the same time
Replacing just one tire is dangerous. It could cause poor handl ing and
poor braking resulting in loss of vehicle control. Toyota strongly recom-
mends that you replace all four tires at the same time. If you replace
only two tires, the new tires should be installed on the rear o f the vehi-
cle.

Using a wrong-sized wheel is dangerous. Braking and handling could
be affected, leading to loss of control and an accident.
NOTICE
A wrong-sized wheel may adversely affect:
●Tire fit
●Wheel and bearing life
●Ground clearance
●Snow-chain clearance
●Speedometer calibration

If Trouble Arises
If your Toyota is equipped with the optional antitheft wheel lug nuts, a
special key must be used to unlock the locking lug nut for each wheel.
The key is stored in the glove compartment, center console stor age,
storage box, or trunk. Register the key and lug nuts with the l ock man-
ufacturer by filling out the r egistration card and mailing it i n using the
accompanying envelope. If the ke y is lost, consult your Toyota dealer
or use the lock manufacturer’s order form to order a new key. A ntitheft
wheel lug nuts cannot be installed on a steel wheel spare tire. When
installing a temporary spare tire, use one of the original lug nuts in
place of the locking lug nut. The original lug nuts are stored inside
your Toyota.
