Maintenance and care
VENZA_OM_OM73030U_(U) Engine coolant
The coolant level is sati sfactory if it is betw een 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.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.

When trouble arises
6035-2. Steps to take in an emergency
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.
Reservoir
“F” line
“L” line
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
