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 8).
With tire pressure monitoring system:
After adjusting the tire pressure, init ialization 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.
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 ty pes 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. 558)
is dangerous. It could seriously affect ride, handling, ground clearance,
tire clearance, and speedometer ca libration. This could cause you to
have an accident. Use only tires that are the correct size specified for
the vehicle.
Tire Inflation Pressure

4405-3. Owner Maintenance
YARIS iA_OM_OM99N89z_(U)
●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 po ssibility of damage from road hazards.
Keep your tire pressure at the correct levels. If one frequently needs
inflating, have it inspected.
During rotation, inspect them for
correct balance.
WARNING
■Always inflate the tires to the correct pressure
Overinflation or underinflation of tires is dangerous. Adverse handling or
unexpected tire failure could re sult in a serious accident.
Refer to Tires on ( →P. 558).
■Use only a Toyota-genuine tire valve cap
Use of a non-genuine part is danger ous as the correct tire air pressure
cannot be maintained if the tire valv e becomes damaged. If the vehicle
is driven under this condition, the tire air pr essure 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.

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. 558) and
inspect the lug nu ts for tightness.
With tire pressure monitoring system:
After adjusting the tire pressure, init ialization 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.
WARNING
■Rotate tires periodically
Irregular tire wear is dangerous. To equalize tire wear and extend tire
life, Toyota recommends that tire rotation is carried out at the same
interval as tire inspection.
For scheduled maintenance information, please refer to the “Owner’s
Manual Supplement/Scheduled Maintenance Guide”.
NOTICE
Rotate unidirectional tires and radial tires that have an asymmetrical
tread pattern or studs only from front to rear, not from side to side. Tire
performance will be reduced if rotated from side to side.

Maintenance and Care
Inspect the temporary spare tire at least monthly to make sure it is
properly inflated and stored.
The temporary spare tire is easier to handle because of its construc-
tion which is lighter and smaller than a conventional tire. This tire
should be used only for an emergen cy and only for a short distance.
Use the temporary spare tire only until the conventional tire is
repaired, which should be as soon as possible.
Refer to Tires on P. 558.
●The temporary spare tire condition gradually deteriorates even if it has
not been used.
●Tires degrade over time, even when 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 ho t 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 indicated by a 4-digit number.
Refer to Tire Labeling on P. 530.
Proper tire balancing provides the best riding comfort and helps
reduce tread wear. Out-of-balance tires can cause vibration and
uneven wear, such as cupping and flat spots.
When replacing a wheel, make sure the new one is the same as the orig-
inal factory wheel in diameter, rim width, and offset (inset/outset).
For details, contact your Toyota dealer.
Temporary Spare Tire
NOTICE
●Do not use your temporary spare tire rim with a snow tire or a conven-
tional tire. Neither will properly fit and could damage both tire and rim.
●The temporary spare tire has a tread life of less than 3,000 miles
(5,000 km). The tread life may be shorter depending on driving condi-
tions.
●The temporary spare tire is for limited use, however, if the tread wear
solid-band indicator appears, replace the tire with the same type of
temporary spare (→P. 443).

If Trouble Arises
Your Toyota has a temporary spare tire. The temporary spare tire is
lighter and smaller than a conventional tire, and is designed only for
emergency use and should be used only for VERY short periods.
Temporary spare tires should NEVER be used for long drives or
extended periods.
■To remove the spare tire
Lift the trunk mat.
Turn the spare tire hold-down
bolt counterclockwise.
■To secure the spare tire
Store the spare tire in the reverse order of removal. After storing,
verify that the spare tire is stored securely.

WARNING
■Do not install the temporary spare tire on the front wheels (driving
wheels)
Driving with the temporary spare tire on one of the front driving wheels
is dangerous. Handling will be affected . You could lose control of the
vehicle, especially on ice or snow bound roads, and have an accident.
Move a regular tire to the front wheel and install the temporary spare tire
to the rear.
