tC_OM_OM21042U_(U)
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 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.

CAUTION
■
When working near the electric c ooling 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 fans may automatically start to run if the air conditioning
is on and/or the coolant temperature is high. ( P. 303)
Vehicles with a smart key system
Be sure the “ENGINE START STOP” switch is off. With the “ENGINE START
STOP” switch in IGNITION ON mode, the electric cooling fans may automat\
-
ically start to run if the air conditioning is on and/or the coolant temperature
is high. ( P. 303)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting your 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 com-
partment.

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” line
“LOW” line
If the level is on or below the
“LOW” line, add coolant up to the
“FULL” line. (P. 413)
■Coolant selection
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.
U.S.A.: “Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deionized water. (Minimum temperature: -31 F [-35 C])
Canada: “Toyota Super Long Life Coolant” is a mixture of 55% coolant and 45% deionized water. (Minimum temperature: -44 F [-42 C])
For more details about engine coolant, contact your Scion dealer.
■ 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 your Scion dealer test the cap and check for
leaks in the cooling system.

If your vehicle overheats
If your engine overheats:
Stop the vehicle in a safe place and turn off the air condi-
tioning system.
Check to see if steam is coming out from under the hood.
If you see steam: 
Stop the engine. Carefully lift the hood after the steam
subsides and then restart the engine.
If you do not see steam: 
Leave the engine running and carefully lift the hood.
Check to see if the cooling fans are operating.
If the fans are operating: 
Wait until the high coolant temperature warning light
goes off and then stop the engine.
If the fans are not operating: 
Stop the engine immediately and call your Scion dealer.
After the engine has cooled
down sufficiently, check the
engine coolant level and
inspect the radiator core (radi-
ator) for any leaks.STEP 1

CAUTION
■
To prevent an accident or injury when inspecting under the hood of
your vehicle
● 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 injuries such as burns.
● Keep hands and clothing away from the fans and drive belt while the
engine is running.
● Do not loosen the coolant reservoir cap while the engine and radiator are
hot.
Serious injury, such as burns, may result from hot coolant and steam
released under pressure.
NOTICE
■When adding engine coolant
Wait until the engine has cooled down before adding engine coolant. 
When adding coolant, do so slowly. Adding cool coolant to a hot engine too
quickly can cause damage to the engine.
