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.
■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.
Except Canada:“Toyota Super Long Life Coolant” is a mixture of 50% cool- ant and 50% deionized water. (Enabled: -31 °F [-35 °C])

CAUTION
nTo prevent an accident or injury when inspecting under the hood of
your vehicle
lIf 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.
l Keep hands and clothing away from the fan and other belts while the
engine is running.
l Do not loosen the radiator cap while the engine and radiator are hot.

When adding coolant, do so slowly. Adding cool coolant to a hot engine too
quickly can cause damage to the engine.
