Maintenance and Care
WARNING
■Do not perform maintenance work if you lack sufficient knowledge and
experience or the proper tools and equipment to do the work. Have
maintenance work done by a qualified technician
Performing maintenance work on a vehicle is dangerous if not done prop-
erly. You can be seriously injured while performing some maintenance pro-
cedures.
■ If you must run the engine while working under the hood, make certain
that you remove all jewelry (especially rings, bracelets, watches, and
necklaces) and all neckties, scarves, and similar loose clothing before
getting near the engine or cooling fan which may turn on unexpectedly
Working under the hood with the engine running is dangerous. It becomes
even more dangerous when you wear jewelry or loose clothing.
Either can become entangled in moving parts and result in injury.
■ 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. The fan could
continue running indefinitely even if the engine has stopped and the engine
compartment temperature is high. You could be hit by the fan and seriously
injured.
■ Do not leave items in the engine compartment
After you have finished checking or doing servicing in the engine compart-
ment, do not forget and leave items such as tools or rags in the engine com-
partment.
Tools or other items left in the engine compartment could cause engine
damage or a fire leading to an unexpected accident.

YARIS_SEDAN_OM_OM99M18z_(U)
Only use SAE 0W-20 oil “Certi-
fied For Gasoline Engines” by
the American Petroleum Insti-
tute (API).
Oil with this trademark symbol
conforms to the current engine
and emission system protection
standards and fuel economy
requirements of the Interna-
tional Lubricant Standardiza-
tion and Approval Committee
(ILSAC), comprised of U.S. and
Japanese automobile manufac-
turers.
Be sure the vehicle is on a level surface.
Warm up the engine to normal operating temperature.
Turn it off and wait at least 5 minutes for the oil to return to the oil
pan.
Pull out the dipstick, wipe it
clean, and reinsert it fully.Full
OK
Low
Pull it out again and examine the level. The level is normal if it is
between Low and Full.
If it is near or below Low, add enough oil to bring the level to Full.
Make sure the O-ring on the dipstick is positioned properly before
reinserting the dipstick.
Reinsert the dipstick fully.

Maintenance and Care
Engine Coolant
Inspect the antifreeze protection and coolant level in the coolant res-
ervoir at least once a year—at the beginning of the winter season—
and before traveling where temperatures may drop below freezing.
Inspect the condition and connections of all cooling system and
heater hoses.
Replace any that are swollen or deteriorated.
The coolant should be at full in the
radiator and between the F and L
marks on the coolant reservoir
when the engine is cool.Cooling fan
Cooling system cap
Coolant reservoir
If it is at or near L, add enough coolant to the coolant reservoir to pro-
vide freezing and corrosion protection and to bring the level to F.
Securely tighten the coolant reservoir tank cap after adding coolant.
If the coolant reservoir is empty or new coolant is required frequently,
consult your Toyota dealer.
Changing the coolant should be done by your Toyota dealer.

WARNING
■Do not use a match or live flame in the engine compartment. DO NOT
ADD COOLANT WHEN THE ENGINE IS HOT
A hot engine is dangerous. If the engine has been running, parts of the
engine compartment can become very hot. You could be burned. Carefully
inspect the engine coolant in the coolant reservoir, but do not open it.
■ 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. The fan could
continue running indefinitely even if the engine has stopped and the engine
compartment temperature is high. You could be hit by the fan and seriously
injured.
■ Do not remove either cooling system cap when the engine and
radiator are hot
When the engine and radiator are hot, scalding coolant and steam may
shoot out under pressure and cause serious injury.

Maintenance and Care
NOTICE
●Radiator coolant will damage paint. Rinse it off quickly if spilled.
● Use only soft (deionized) water in the coolant mixture. Water that 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 Silicate.
These coolants could damage the cooling system.
● DO NOT MIX alcohol or methanol with the coolant. This could damage the
cooling system.
● Do not use a solution that contains more than 60% antifreeze.
This would reduce effectiveness.
● Use of engine coolant specifically designed for the YARIS SEDAN is
required when replacing engine coolant. Using engine coolant that is not
specifically designed for this vehicle may cause serious damage to the
engine and cooling system. For questions on how to obtain this specially
designed coolant, contact your Toyota dealer.

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.
