Maintenance and Care
Wiper Blades
Contamination of either the windshield or the blades with for-
eign matter can reduce wiper effectiveness. Common sources
are insects, tree sap, and hot wax treatments used by some
commercial car washes.
If the blades are not wiping properly, clean the window and
blades with a good cleaner or mild detergent; then rinse thor-
oughly with clean water. Repeat if necessary.
NOTICE
●Hot waxes applied by automatic car washers have been known to affect
the wiper’s ability to clean windows.
● To prevent damage to the wiper blades, do not use gasoline, kerosene,
paint thinner, or other solvents on or near them.

or cracked.
Replace them.Raise the wiper arm and turn
the blade assembly to expose
the plastic locking clip.
Compress the clip and slide the
assembly downward; then lift it
off the arm.
Hold the end of the rubber and
pull until the tabs are free of the
metal support.Metal support

Maintenance and Care
NOTICE
●To prevent damage to the wiper arms and other components, do not try to
sweep the wiper arm by hand.
● To prevent damage to the windshield let the wiper arm down easily, do not
let it slap down on the windshield.
● Do not bend or discard the stiffeners. You need to use them again.
● If the metal stiffeners are switched, the blade’s wiping efficiency could be
reduced.
So don’t use the driver’s side metal stiffeners on the passenger’s side, or
vice versa.
● Be sure to reinstall the metal stiffeners in the new blade rubber so that the
curve is the same as it was in the old blade rubber.
● When raising both windshield wiper arms, raise the driver’s side wiper arm
first. When lowering the wiper arms, slowly lower the wiper arm from the
passenger’s side first while supporting it with your hand. Forcefully lower-
ing the wiper arms could damage the wiper arm and blade, and may
scratch or crack the windshield.

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 6 0).
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. 560)
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_OM99Q46z_(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. 560).
■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 c ondition, 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.
