If your vehicle overheats
The following may indicate that your vehicle is overheating.
●The high engine coolant temperat ure warning light flashers or
comes on or a loss of power is experienced.
● Steam is coming from under the hood.
Follow the correction pro cedure as described below.
Stop the vehicle in a safe place and turn off the air condi-
tioning system, and then stop the engine.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam: Carefully lift the hood.
After the engine has cooled
down sufficiently, inspect the
hoses and radiator core (radi-
ator) for any leaks.

The coolant level is satisfac-
tory if it is between the “FULL”
and “LOW” lines on the reser-
voir. (
P. 229)
Reservoir
“FULL”
“LOW”
Add coolant if necessary.
Water can be used in an emer-
gency if coolant is unavailable.
Start the engine and turn the ai r conditioning system on to
check that the radiator cooling fan operates and to check
for coolant leaks from the radiator or hoses.
The fan operates when the air conditioning system is turned on
immediately after a cold start. Confirm that the fan is operating by
checking the fan sound and air flow. If it is difficult to check these,
turn the air conditioning system on and off repeatedly.
(The fan may not operate in freezing temperatures.)
If the fan is not operating:
Stop the engine immediately and contact your Scion
dealer.
If the fan is operating: Have the vehicle inspected at the nearest Scion dealer.

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.
■ To prevent damage to the cooling system
Observe the following precautions:
● Avoid contaminating the coolant with foreign matter (such as sand or dust
etc.).
● Do not use commercially available coolant additives.
