CAUTION
■When working near the electric cooling fan or radiator grille
Vehicles with smart key system
Be sure the “ENGINE START STOP” switch is turned OFF. With the
“ENGINE START STOP” switch in IGNITION ON mode, the electric cooling
fan may automatically start to run if the air conditioning is on and/or the cool-
ant temperature is high. (P. 401)
Vehicles without smart key system
Be sure the engine switch is OFF. With the engine switch in the “ON” posi-
tion, the electric cooling fan may automatically start to run if the air condition-
ing is on and/or the coolant temperature is high. (P. 401)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air. Also a backfire could cause a fire in the engine compart-
ment.

Engine coolant
The coolant level is satisfactory if it is between the “F” and “L” lines on
the reservoir when the engine is cold.
Reservoir cap
Full
Low
If the level is on or below the “L”
line, add coolant up to the “F” line.
■If the coolant level drops within a short time after replenishing
Visually check the radiator, hoses, coolant reservoir cap, radiator cap, drain
cock and water pump.
If you cannot find a leak, have your Toyota dealer pressure test the cap and
check for leaks in the cooling system.
■Coolant selection
Only use “Toyota Super Long Life Coolant” or similar high quality ethylene
glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant
with long-life hybrid organic acid technology.
U.S.A.: “Toyota Super Long Life Coolant” is a mixture of 50 % coolant and
50 % deionized water. (Enabled: -31F [-35C])
Canada: “Toyota Super Long Life Coolant” is a mixture of 55 % coolant
and 45 % deionized water. (Enabled: -44F [-42C])
For more details about coolant, contact your Toyota dealer.

Radiator and condenser
Check the radiator and condenser and clear any foreign objects.
If either of the above parts are extremely dirty or you are not sure of
their condition, have your vehicle checked by your Toyota dealer.
CAUTION
■When the engine is hot
Do not remove the radiator cap.
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing burns or other injuries.
NOTICE
■When adding the coolant
Coolant is neither plain water nor straight antifreeze. The correct mixture of
water and anti freeze must be used to provide proper lubrication, corrosion
protection and cooling. Be sure to read the antifreeze or coolant label.
■If you spill coolant
Be sure to wash it off with water to prevent it from damaging to parts or paint.
CAUTION
■When the engine is hot
Do not touch the radiator or condenser, as they may be hot and you may be
burned.

5-2. Steps to take in an emergency
AVALON_U (OM41428U)
If your vehicle overheats
If your engine overheats:
Stop the vehicle in a safe place and turn off the air condi-
tioning system.
Check to see if steam is coming out from under the hood.
If you see steam:
Stop the engine. Carefully lift the hood after the steam
subsides and then restart the engine.
If you do not see steam:
Leave the engine running and carefully lift the hood.
Check to see if the cooling fan is operating.
If the fan is operating:
Wait until the engine coolant temperature gauge begins
to fall and then stop the engine.
If the fan is not operating:
Stop the engine immediately and call your local Toyota
dealer.
After the engine has cooled
down sufficiently, check the
coolant level and inspect the
radiator core (radiator) for any
leaks.
If the engine compartment
cover needs to be removed.
