Maintenance and care
n
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.
n Coolant selec
tion
Only use “Toyota Super Long Life Coolant” or similar high quality ethylene
glycol based n
on-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])
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
n 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 burns or other injuries.
NOTICE
nWhen adding engine coolant
Coolant is neither plain water nor strai ght antifreeze. The correct mixture of
water and antifreeze must be used to provide proper lubrication, corrosion
protection and cooling. Be sure to read the antifreeze or coolant label.
n If you spill coolant
Be sure to wash it off with water to prevent damage to parts or paint.

CAUTION
nTo prevent an accident or injury when inspecting un der the hood of
your vehicle
l 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.
l Keep hands and clothing away from the fan and other belts while the
engine is running.
