Maintenance and Care
WARNING
■Do not use a match or live flame in the engine compartment. DO NOT
ADD COOLANT WHEN THE ENGINE IS HOT

engine compartment can become very hot. You could be burned. Ca refully
inspect the engine coolant in the coolant reservoir, but do not open it.
■ Pull over to a safe location, then switch the ignition to off and
make sure the fan is not running before attempting to work near the
cooling fan
Working near the cooling fan when it is running is dangerous. T he fan could
continue running indefinitely even if the engine has stopped an d the engine
compartment temperature is high. You could be hit by the fan an d seriously
injured.
■ Do not remove either cooling system cap when the engine and

NOTICE
●Radiator coolant will damage paint. Rinse it off quickly if spi lled.
● Use only soft (deionized) water in the coolant mixture. Water t hat contains
minerals will cut down on the coolant’s effectiveness.
● Do not add only water. Always add a proper coolant mixture.
● The engine has aluminum parts and must be protected by an ethylene-gly-
col-based coolant to prevent corrosion and freezing.
● DO NOT USE coolants Containing Alcohol, methanol, Borate or Sil icate.
These coolants could damage the cooling system.
● DO NOT MIX alcohol or methanol with the coolant. This could dam age the
cooling system.
● Do not use a solution that contains more than 60% antifreeze.
This would reduce effectiveness.
●
Use of engine coolant specifical ly designed for the YARIS/YARIS HATCHBACK
is required when replacing engine coolant. Using engine coolant that is not spe-
cifically designed for this veh icle may cause serious damage to the engine and
cooling system. For questions on how to obtain this specially d esigned coolant,
contact your Toyota dealer.

Maintenance and Care
Brake/Clutch Fluid
The brakes and clutch draw fluid from the same reservoir.
Inspect the fluid level in the reser-
voir regularly. It should be kept
between the MAX and MIN lines.
The level normally drops with
accumulated distance, a condition
associated with wear of brake and
clutch linings. If it is excessively
low, have the brake/clutch system
inspected by your Toyota dealer.
Inspecting Brake/Clutch Fluid Level
WARNING
■ If the brake/clutch fluid level is low, have the brakes inspect ed
A low brake/clutch fluid level is dangerous.
A low level could indicate brake lining wear or a brake system leak which
could cause the brakes to fail and lead to an accident.

Window Washer Fluid
Inspect fluid level in the washer
fluid reservoir; add fluid if neces-
sary.
Use plain water if washer fluid is unavailable.
But use only washer fluid in cold weather to prevent it from freezing.
●State or local regulations may restrict the use of volatile org anic compounds
(VOCs), which are commonly used as anti-freeze agents in washer fluid. A
washer fluid with limited VOC content should be used only if it provides ade-
quate freeze resistance for all regions and climates in which t he vehicle will
be operated.
● Front and rear washer fluid is supplied from the same reservoir .

WARNING
■Use only windshield washer fluid or plain water in the reservoir
Using radiator antifreeze as washer fluid is dangerous. If sprayed on the
windshield, it will dirty the windshield, affect your visibilit y, and could result
in an accident.
■ Using Washer Fluid Without Anti- freeze Protection in Cold Weather
Operating your vehicle in temperatures below 40 °F (4 °C) using washer
fluid without anti-freeze protection is dangerous as it could c ause impaired
windshield vision and result in an accident. In cold weather, a lways use
washer fluid with anti-freeze protection.

Maintenance and Care
Body Lubrication
All moving points of the body, such as door and hood hinges
and locks, should be lubricated each time the engine oil is
changed. Use a nonfreezing lubricant on locks during cold
weather.
Make sure the hood’s secondary latch keeps the hood from
opening when the primary latch is released.

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.

ON, the wipers may move automatically in the following cases
● If the windshield above the rain sensor is touched.
● If the windshield above the rain sensor is wiped with a cloth.
● If the windshield is struck with a hand or other object.
● If the rain sensor is struck with a hand or other object from i nside the vehi-
cle.
Be careful not to pinch hands or fingers as it may cause injury , or damage
the wipers. When washing or servicing the vehicle, make sure the wiper
lever is in the OFF position.
NOTICE
● Hot waxes applied by automatic car washers have been known to a ffect
the wiper’s ability to clean windows.
● To prevent damage to the wiper blades, do not use gasoline, ker osene,
paint thinner, or other solvents on or near them.
