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.

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.
