Reservoir cap
Full
Low If the level is on or below the “L”
line, add coolant up to the “F” line.NOTICE■ To prevent serious engine damage
Check the oil level on regular basis.
■ When replacing the engine oil
● Be careful not to spill engine oil on the vehicle components.
● Avoid overfilling, or the engine could be damaged.
● Check the oil level on the dipstick every time you refill the vehicle.
● Be sure the engine oil filler cap is properly retightened.

4984-3. Do-it-yourself maintenance
VENZA_OM_OM73030U_(U) ■ 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.

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-

VENZA_OM_OM73030U_(U) If your vehicle overheats Correction procedures
Stop 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.
Radiator
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.

Radiator capThe 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. STEP 1

6045-2. Steps to take in an emergency
VENZA_OM_OM73030U_(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

When trouble arises
6055-2. Steps to take in an emergency
VENZA_OM_OM73030U_(U) CAUTION■ To prevent an accident or injury wh en inspecting under the hood of
your vehicle
● If steam is seen coming from under the hood, do not open the hood until
the steam has subsided. The engine compartment may be very hot, caus-
ing serious injury such as burns.
● Keep hands and clothing (especially a tie, a scarf or a muffler) away from
the fans and belts. Failure to do so may cause the hands or clothing to be
caught, resulting in serious injury.
● Do not loosen the radiator cap while the engine and radiator are hot.
Serious injury, such as burns, may result from hot coolant and steam
released under pressure.
NOTICE■ When adding engine coolant
Wait until the engine has cooled down before adding engine coolant.
When adding coolant, do so slowly. Adding cool coolant to a hot engine too
quickly can cause damage to the engine.
■ To prevent damage to the cooling system
Observe the following precautions:
● Avoid contaminating the coolant with foreign matter (such as sand or dust
etc.).
● Do not use any coolant additive.
