Maintenance and care
Engine coolant
The coolant level is satisfactory if it is between the “FULL” and “LOW”
lines on the reservoir when the engine is cold.
Reservoir cap
“FULL”
“LOW”
If the level is on or below the
“LOW” line, add coolant up to the
“FULL” line. (P. 416)
■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 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 coolant reservoir cap.
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing burns or other injuries.

■ Checking fluid level
The brake fluid level should be
between the “MAX” and “MIN”
lines on the tank.

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
