Maintenance and care
CAUTION
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury observe the following precautions.
■When working on the engine compartment
●Keep hands, clothing, and tools away from the moving fan and engine
drive belt.
●Be careful not to touch the engine, radiator, exhaust manifold, etc. right
after driving as they may be hot. Oil and other fluids may also be hot.
●Do not leave anything that may burn easily, such as paper or rags, in the
engine compartment.
●Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
●Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
●Take care because brake fluid can harm your hands or eyes and damage
painted surfaces.
If fluid gets on your hands or in your eyes, flush the affected area with
clean water immediately.
If you still experience discomfort, see a doctor.
■When working near the electric cooling fans or radiator grille
Be sure the engine switch is OFF. With the engine switch in the “ON” posi-
tion, the electric cooling fans may automatically start to run if the air condi-
tioning is on and/or the coolant temperature is high. (P. 301)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.

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. 391)
■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.

Maintenance and care
Radiator and condenser
Check the radiator and condenser and remove any foreign objects.
If any of the above parts are extremely dirty or you are not sure of
their condition, have your vehicle checked by your Toyota dealer.
NOTICE
■When adding engine coolant
Coolant is neither plain water nor straight 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.
■If you spill coolant
Be sure to wash it off with water to prevent damage to parts or paint.
CAUTION
■When the engine is hot
Do not touch the radiator or condenser, as they may be hot and may cause
burns.
