CAUTION
■
When working near the electric cooling fan or radiator grille
Vehicles without smart entry & start system: Be sure the engine switch is in
the “LOCK” position.
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. 379)
Vehicles with smart entry & start system: Be sure the “ENGINE START
STOP” switch is OFF.
With the “ENGINE START STOP” switch in the IGNITION ON mode, the
electric cooling fan may automatically st art to run if the air conditioning is on
and/or the coolant temperature is high. ( →P. 379)
■ 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. Also a backfire could cause a fire in the engine compart-
ment.
■ If the brake fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious problem.

Engine coolant
The coolant level is satisfactory if it is between the “FULL” and “LOW ”
lines on the reservoir when the engine is cold.
Gasoline engine Reservoir cap
“FULL”
“LOW ”
If the level is on or below the
“LOW ” line, add coolant up to the
“FULL” line.
Diesel engine
Reservoir cap

■ 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 any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional, 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.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50%
deionized water. (Enabled: -35 °C [-31 °F])
For more details about engine coolant, contact any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.
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 serious injuries, such as burns.

dealer or repairer, or another duly qualified and equipped profes-
sional.
NOTICE
■ When adding engine coolant
Coolant is neither plain water nor stra ight 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, condenser or intercooler, as they may be hot and
may cause serious injuries, such as burns.
