CAUTION
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury observe the following precautions.
■
When working on the engine compartment
●Keep hands, clothing, and tools away from the moving fan and engine
drive belt.
● Be careful not to touch the engine, inverter, radiator, exhaust manifold, etc.
right after driving as they may be hot. Oil and other fluids may also be hot.
● Do not leave anything that may burn easily, such as paper or rags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
● Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.

VENZA_OM_OM73023U_(U)
CAUTION
■When working near the electric cooling fan or radiator grille
Vehicles with smart key system
Be sure the “ENGINE START STOP” switch is 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 if the coolant
temperature is high. ( P. 499)
Vehicles without smart key system
Be sure the engine switch is in the “LOCK” position. With the engine
switch in the “ON” position, the electric cooling fan may automati\
cally
start to run if the air conditioning is on and/or if the coolant temperature is
high. ( P. 499)
■ When working on or under the vehicle
Do not get under the vehicle with just the jack supporting it.
Always use automotive jack stands or other solid supports.
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in your 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.

■If the coolant level drops within a short time after replenishing
Visually check the radiator, hoses, 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 engine coolant, contact 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 serious injuries, such as burns.

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 vehicl e checked by your Toyota dealer.
NOTICE
■When adding the engine coolant
Coolant is neither plain water nor stra ight antifreeze. The correct mixture of
water and antifreeze 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 damage to parts or paint.
CAUTION
■When the engine is hot
Do not touch the radiator or condenser as they may be hot and cause seri-
ous injuries, such as burns.

If your vehicle overheats
Correction proceduresStop the vehicle in a safe place and turn off the air condition-
ing system, and then stop the engine.
If you see steam: Carefully lift the hood after the steam subsides.
If you do not see steam: Carefully lift the hood.
After the engine has cooled
down sufficiently, inspect the
hoses and radiator core (radia-
tor) for any leaks.

Cooling fans
If a large amount of coolant leaks,
immediately contact your Toyota
dealer.
The coolant level is satisfactory if
it is between the “F” and “L ” lines
on the reservoir.Reservoir
“F” line

The following may indicate that your vehicle is overheating.
● The engine coolant temperature gauge ( P. 188) reaches the
maximum, or a loss of engine po wer is experienced. (For exam-
ple, the vehicle speed does not increase.)
● Steam comes out from under the hood.

VENZA_OM_OM73023U_(U)Add coolant if necessary.
Water can be used in an emer-
gency if coolant is unavailable.
Start the engine and turn the
air conditioning system on to
check that the radiator cooling fans operate and to check for
coolant leaks from t he radiator or hoses.
The fans operate when the air conditioning system is turned
on immediately after a cold star t. Confirm that the fans are
operating by checking the fan sound and air flow. If it is diffi-
cult to check these, turn the air conditioning system on and off
repeatedly.
(The fans may not operate in freezing temperatures.)
If the fans are not operating: Stop the engine immediately and contact your Toyota
dealer.
If the fans are operating: Have the vehicle inspected at the nearest Toyota dealer.
