Engine Coolant
Inspect the antifreeze protection and coolant level in the cool ant res-
ervoir at least once a year—at the beginning of the winter seas on—
and before traveling where temperatures may drop below freezing .
Inspect the condition and connec tions of all cooling system and
heater hoses.
Replace any that are sw ollen 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 reserv oir to pro-
vide freezing and corrosion prote ction and to bring the level to F.
Securely tighten the coolant re servoir tank cap after adding co olant.
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.

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
A hot engine is dangerous. If the engine has been running, part s of the
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
radiator are hot
When the engine and radiator are hot, scalding coolant and steam may
shoot out under pressure and cause serious injury.

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.

6-5. Overheating
Overheating
If the high engine coolant temperature warning light turns on:
Drive safely to the side of the road and park off the right-of-way.
Put a vehicle with an automatic t ransaxle in park (P), a manual tran-
saxle in neutral.
Apply the parking brake.
Turn off the air conditioner.
Check whether coolant or steam is escaping from the engine com-
partment.
If steam is coming from the engine compartment
Do not go near the front of t he vehicle. Stop the engine.
Wait until the steam dissipates, then open the hood and start the
engine.
If neither coolant nor steam is escaping
Open the hood and idle the engine until it cools.
Make sure the cooling fan is operating, then turn off the engin e after
the temperature has decreased.
When cool, check th e coolant level.
If it is low, look for coolant lea ks from the radiator and hoses.
■If you find a leak or other damage, or if coolant is still leak ing:
Stop the engine and call your Toyota dealer.
Cooling fan
Cooling system cap
Coolant reservoir
If the high engine coolant temperature warning light turns on,
the vehicle loses power, or you hear a loud knocking or pinging
noise, the engine is probably too hot.

If Trouble Arises
■If you find no problems, the engine is cool, and no leaks are
obvious:
Carefully add coolant as required (P. 398).
WARNING
■ 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
radiator are hot
When the engine and radiator are hot, scalding coolant and steam may
shoot out under pressure and cause serious injury.
■ Open the hood ONLY after steam is no longer escaping from the e ngine
Steam from an overheated engine is dangerous. The escaping stea m could
seriously burn you.
NOTICE
● If the cooling fan does not operate while the engine is running, the engine
temperature will increase. Stop the engine and call your Toyota dealer.
● If the engine continues to overheat or frequently overheats, ha ve the cool-
ing system inspected. The engine could be seriously damaged unl ess
repairs are made. Consult your Toyota dealer.

If Trouble Arises
(Red)
High Engine Coolant Temperature Warning LightThe light flashes when the engine coolant temperature is
extremely high, and illuminates when the engine coolant
temperature increases further.
Handling Procedure:
• Flashing light
Drive slowly to reduce engine load until you can find a
safe place to stop the vehicle and wait for the engine to
cool down.
• Illuminated light This indicates the possibility of overheating. Park the
vehicle in a safe place immediately and stop the engine.
Refer to Overheating P. 484.
Power Steering Malfunction Indicator Light
The light illuminates/flashes if the electric power steering
has a malfunction.
If the light illuminates/flashes, stop the vehicle in a safe
place and do not operate the steering wheel. There is no
problem if the light turns off after a while. Contact your
Toyota dealer if the light illuminates/flashes continuously.

■Power Steering Malfunction Indicator Light
●If the indicator light illuminates/flashes, the power steering will not operate
normally. If this happens, the steering wheel can still be operated, however,
the operation may feel heavy compared to normal, or the steering wheel
could vibrate when turning.
● Repeatedly jerking the steering wheel left and right while the vehicle is
stopped or moving extremely slowly will cause the power steerin g system to
go into protective mode which will make the steering feel heavy , but this
does not indicate a problem. If this occurs, park the vehicle safely and wait
several minutes for the system to return to normal.
WARNING
■ Do not drive with the brake system warning light illuminated. C ontact
your Toyota dealer to have the brakes inspected as soon as poss ible
Driving with the brake system warning light illuminated is dang erous. It indi-
cates that your brakes may not work at all or that they could c ompletely fail
at any time. If this light remains illuminated, after checking that the parking
brake is fully released, have the brakes inspected immediately.
In addition, the effectiveness of the braking may diminish so y ou may need
to depress the brake pedal more strongly than normal to stop th e vehicle.
■ Do not drive with both the ABS warning light and brake warning light
illuminated. Have the vehicle towed to your Toyota dealer to have the
brakes inspected as soon as possible
Driving when the brake system warning light and ABS warning lig ht are illu-
minated simultaneously is dangerous.
When both lights are illuminated, the rear wheels could lock mo re quickly in
an emergency stop than under normal circumstances.
NOTICE
■ Charging System Warning Light
Do not continue driving when the charging system warning light is illumi-
nated because the engine could stop unexpectedly.
■ Engine Oil Warning Light
● Do not run the engine if the oil pressure is low. Otherwise, it could result in
extensive engine damage.
● Do not run the engine if the oil level is low. Otherwise, it co uld result in
extensive engine damage.
■ High Engine Coolant Temperature Warning Light
Do not drive the vehicle with the high engine coolant temperatu re warning
light illuminated. Otherwise, it could result in damage to the engine.
