2-9. Driving Tips
Winter Driving
Carry emergency gear, including tire chains, window scraper, flares, a
small shovel, jumper cables, and a small bag of sand or salt.
Ask your Toyota dealer to check the following:
• Have the proper ratio of ant ifreeze in the radiator.
Refer to Engine Coolant on P. 398.
• Inspect the battery and its cabl es. Cold reduces battery capacity.
• Use an engine oil appropriate for the lowest ambient temperatures that the vehicle w ill be driven in (P. 395).
• Inspect the ignition system for damage and loose connections.
• Use washer fluid made with antifreeze but do not use engine cool-
ant antifreeze for washer fluid ( P. 402).
●Do not use the parking brake in freezing weather as it may freeze. Instead,
shift to 1 or R with a manual transaxle and to P with an automa tic transaxle.
Block the rear wheels.
● Remove snow before driving. Snow left on the windshield is dang erous as it
could obstruct vision.
● Do not apply excessive force to a window scraper when removing ice or fro-
zen snow on the mirror glass and windshield.
● Never use warm or hot water for removing snow or ice from windo ws and
mirrors as it could result in the glass cracking.
● Drive slowly. Braking performance can be adversely affected if snow or ice
adheres to the brake components. If this situation occurs, drive the vehicle
slowly, releasing the accelerator pedal and lightly applying the brakes sev-
eral times until the brake performance returns to normal.

3-4. Switches and Controls

When Driving
Windshield Wipers and Washer
The ignition must be switched ON to use the wipers.
Because heavy ice and snow can jam the wiper blades, the wiper motor is
protected from motor breakdown, overheating and possible fire b y a circuit
breaker. This mechanism will automatically stop operation of th e blades, but
only for about 5 minutes.
If this happens, turn off the wiper switch and park off the rig ht-of-way, and
remove the snow and ice.
After 5 minutes, turn on the switch and the blades should opera te normally. If
they do not resume functioning, consult your Toyota dealer as s oon as possi-
ble. Drive to the side of the road and park off the right-of-wa y. Wait until the
weather clears before trying to drive with the wipers inoperative.
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.
■ Only use windshield washer fluid mixed with anti-freeze protect ion in
freezing weather conditions
Using windshield washer fluid without anti-freeze protection in freezing
weather conditions is dangerous as it could freeze on the windshield and
block your vision which could cause an accident. In addition, m ake sure the
windshield is sufficiently warmed using the defroster before spraying the
washer fluid.

5-3. Owner Maintenance
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.

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.

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.

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.
