Maintenance and care
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 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 and 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, consult a doctor.
■When working near the electric cooling fans or radiator grille
Vehicles without a smart entry & start system:
Be sure the engine switch is off.
With the engine switch in the “ON” position, the electric cooling fan may
automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. (P. 476)
Vehicles with a smart entry & start system:
Be sure the engine switch is off.
With the engine switch in IGNITION ON mode, the electric cooling fan may
automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. (P. 476)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.
from getting in your eyes.

Maintenance and care
■Intercooler coolant reservoir (8NR-FTS engine only)
Reservoir cap
“FULL” line
“LOW” line
If the level is on or below the
“LOW” line, add coolant up to
the “FULL” line.
■Coolant selection
Except 1WW engine
Only use “Toyota Super Long Life Coolant” or a similar high quality ethylene
glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with
long-life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deion-
ized water. (Minimum temperature: -35C [-31F])
For more details about engine coolant, contact any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.
1WW engine
Only use “Toyota Genuine Premium Long Life Coolant 1WW/2WW” or equiv-
alent.
“Toyota Genuine Premium Long Life Coolant 1WW/2WW” concentrated prod-
uct always needs to be mixed as 50% coolant and 50% deionized water.
(Minimum temperature: -35C [-31F])
For more details about engine coolant, contact any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.
■If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir caps, drain cock
and water pump.
If you cannot find a leak, have any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional, test the cap and check for
leaks in the cooling system.

WARNING
■When the engine is hot
Do not remove the engine coolant reservoir cap.
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.
