NOTICE
●To prevent damage to the wiper arms and other components, do no t 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.
● To prevent damage to the rear window, do not let the wiper arm fall on it.
● Do not bend or discard the stiffeners. You need to use them aga in.
● 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 passenge r’s side, or
vice versa.
● Be sure to reinstall the metal stiffeners in the new blade rubb er 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 sid e 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. Forc efully lower-
ing the wiper arms could damage the wiper arm and blade, and ma y
scratch or crack the windshield.

Before performing battery mainte-
nance, remove the battery cover
by pressing the tab.Ta b
WARNING
■Wash hands after handling the battery and related accessories
Battery posts, terminals and related accessories contain lead a nd lead com-
pounds, chemicals known to the State of California to cause can cer and
reproductive harm.
■ Read the following precautions carefully before using the bat-
tery or inspecting to ensur e safe and correct handling
■ Always wear eye protection wh en working near the battery
Working without eye protection is dangerous. Battery fluid cont ains SULFU-
RIC ACID which could cause blindness if splashed into your eyes . Also,
hydrogen gas produced during normal battery operation, could ig nite and
cause the battery to explode.
■ Wear eye protection and protect ive gloves to prevent contact
with battery fluid
Spilled battery fluid is dangerous.
Battery fluid contains SULFURIC ACID which could cause serious injuries if
it gets in eyes, or on the skin or clothing. If this happens, i mmediately flush
your eyes with water for 15 minutes or wash your skin thoroughl y and get
medical attention.
■ Always keep batteries out of the reach of children
Allowing children to play near batteries is dangerous. Battery fluid could
cause serious injuries if it gets in the eyes or on the skin.

Maintenance and Care
To get the best service from a battery:
• Keep it securely mounted.
• Keep the top clean and dry.
• Keep terminals and connec- tions clean, tight, and coated
with petroleum jelly or terminal
grease.
• Rinse off spilled electrolyte immediately with a solution of
water and baking soda.
• If the vehicle will not be use d for an extended time, disconne ct the
battery cables and charge the battery every 6 weeks.
Contact your Toyota dealer for a battery replacement purchase.
WARNING
■ Keep flames and sparks away from open battery cells and do
not allow metal tools to contact the positive (+) or negative ( -) terminal
of the battery when working near a battery. Do not allow the positive (+)
terminal to contact the vehicle body
Flames and sparks near open battery cells are dangerous. Hydrog en gas,
produced during normal battery operation, could ignite and cause the bat-
tery to explode. An exploding battery can cause serious burns a nd injuries.
Keep all flames including cigarettes and sparks away from open battery
cells.
■ Keep all flames and sparks away from open battery cells
because hydrogen gas is produced from open battery cells while
charging the battery or adding battery fluid:
Flames and sparks near open battery cells are dangerous. Hydrog en gas,
produced during normal battery operation, could ignite and cause the bat-
tery to explode. An exploding battery can cause serious burns a nd injuries.

If the buttons on the smart key are inoperable and the operation indi-
cator light does not flash, the battery may be dead.
Replace with a new ba ttery before the smart key becomes unusabl e.
The following conditions indicate that the battery power is low :
• The KEY indicator light (green) flashes in the combination met er for
about 30 seconds after the engine is switched OFF.
• The system does not operate and the operation indicator light on
the smart key does not flash when the buttons are pressed.
• The system’s operational range is reduced.
Replacing the battery at your Toyota dealer is recommended to p re-
vent damage to the key. If replac ing the battery by yourself, follow the
instruction below.
■Replacing the key battery

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.
