If the level is on or below the “L”
line, add coolant up to the “F” line.
■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 pressure test the cap and
check for leaks in the cooling system.
■ Coolant selection

glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant
with long-life hybrid organic acid technology.

CAUTION
■To prevent an accident or injury when 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 away from the fan and engine drive belt while the
engine is running.
