2-8. Driving Tips

Before Driving
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 antifreeze in the radiator.
Refer to Engine Coolant on P. 431.
● Inspect the battery and its cables. Cold reduces battery capacity.
● Use an engine oil appropriate for the lowest ambient temperatures
that the vehicle will be driven in ( →P. 429).
● 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. 435).
●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 automatic transaxle.
Block the rear wheels.
● Remove snow before driving. Snow left on the windshield is dangerous 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 windows 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.

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.

6-5. Overheating
Overheating
If the high engine coolant temperature warning light illuminates:
Drive safely to the side of the road and park off the right-of-way.
Put a vehicle with an automatic transaxle in park (P), a manual
transaxle in neutral.
Apply the parking brake.
Turn off the air conditioner.
Check whether coolant or steam is escaping from the engine com-
partment.
XIf steam is coming from the engine compartment:
Do not go near the front of the vehicle. Stop the engine.
Wait until the steam dissipates, then open the hood and start the
engine.
XIf 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 engine after
the temperature has decreased.
When cool, check the coolant level.
If it is low, look for coolant leaks from the radiator and hoses.
■If you find a leak or other damage, or if coolant is still leaking:
Stop the engine and call your Toyota dealer.Cooling fan

If the high engine coolant temperature warning light illuminates,
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. 431).
WARNING
■ 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.
■ Open the hood ONLY after steam is no longer escaping from the engine
Steam from an overheated engine is dangerous. The escaping steam 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, have the cool-
ing system inspected. The engine could be seriously damaged unless
repairs are made. Consult your Toyota dealer.
