WARNING
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 en gine
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 ra gs, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel or t he bat-
tery. Fuel and battery fumes are flammable.
● Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
■ When working near the electric cooling fans or radiator grille
Vehicles without a smart key system: Be sure the engine switch is off. With
the engine switch in the “ON” position, the electric cooling fa ns may auto-
matically start to run if the air conditioning is on and/or the coolant tempera-
ture is high. ( P. 337)
Vehicles with a smart key system: Be sure the “ENGINE START STO P”
switch is off. With the “ENGINE START STOP” switch in IGNITION ON
mode, the electric cooling fans may automatically start to run if the air condi-
tioning is on and/or the coolant temperature is high. ( P. 337)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air.

Maintenance and care
Engine coolant
The coolant level is satisfactory if it is between the “FULL” a nd “LOW”
lines on the reservoir w hen 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.
NOTICE
■To prevent serious engine damage
Check the oil level on a regular basis.
■ When replacing the engine oil
●Be careful not to spill engine oil on the vehicle components.
● Avoid overfilling, or the engine could be damaged.
● Check the oil level on the dipstick every time you refill the v ehicle.
● Be sure the engine oil filler cap is properly tightened.
■If the coolant level drops within a short time after replenishi ng
Visually check the radiator, hoses, engine coolant filler 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.

336 4-3. Do-it-yourself maintenance
■Coolant selection
Only use “TOYOTA Genuine 50/50 Pre-mixed Super Long Life Coolan t
BLUE” or similar high-quality ethylene glycol-based non-silicat e, non-amine,
non-nitrite, and non-borate coolant with long-life hybrid organic acid technol-
ogy.
“TOYOTA Genuine 50/50 Pre-mixed Super Long Life Coolant BLUE” i s a
mixture of 50% coolant and 50% deionized water. (Enabled: -31 F [-35 C])
For more details about engine coolant, contact your Toyota deal er.
WARNING
■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 serious injuries, such as burns.
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 coola nt label.
■ If you spill coolant
Be sure to wash it off with water to prevent it from damaging p arts or paint.
