5-2. Steps to take in an emergency
If your vehicle overheats
In the following cases, the vehicle may be overheating.
●High engine coolant temperature warning light ( P. 274) flashes
or comes on, and engine output falls (There is no speed).
● Steam is coming out from the engine compartment.
Perform the following steps.
Stop the vehicle in a safe place, turn off the air conditioning
system, and stop the engine.
If steam is coming out:
When no more steam is coming out has been confirmed,
carefully open the hood.
If there is no steam coming out:
Carefully open the hood. After the engine has cooled
down sufficiently, inspect the
radiator core (radiator), hoses,
etc. for any leaks.
If there is a large quantity of
engine coolant leaking, imme-
diately contact your Scion
dealer.
Inspect the amount of engine
coolant by checking if the res-
ervoir level is between FULL
and LOW lines.

When trouble arises

5-2. Steps to take in an emergency
Add engine coolant if neces-
sary.
Water can be used in an emer-
gency if engine coolant is
unavailable. (
P. 320)
Start the engine, allow the ai r conditioning system to run
and check that the electric coo ling fan is operating, as well
as double check that there are no leaks at the radiator core
and hoses.
Immediately after starting, after the engine has gotten cold, the
fan operates by turning on the air conditioning system. Check for
fan sound and wind. If it is difficult to determine, repeatedly turn
the air conditioning system on and off.
(However, in cold weather where temperatures go below freezing,
the fan will not operate.)
If the fan does not operate:
Stop the engine immediately and contact your Scion dealer.
If the fan operates:
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 injury such as burns.
● Keep hands and clothing away from the fan and other belts 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.

320 6-1. Specifications
The 0W portion of the oil viscosity rating indicates the characteristic of the
oil which allows cold startability. Oils with a lower value before the W allow
for easier starting of the engine in cold weather.
The 20 in 0W-20 indicates the oil viscosity when the oil is at its operating
temperature. An oil with a higher viscosity may be better suited if the vehi-
cle is operated at high speeds, or under extreme load conditions.
How to read oil container label:
The ILSAC (International Lubricant Standardization and Approval
Committee) Certification Mark is added to some oil containers to help
you select the oil you should use.

• “Toyota Super Long Life Coolant”
• Similar high-quality ethylene glycol-based non-silicate, non-amine, non-nitrite and
non-borate coolant with long-life hybrid
organic acid technology
Do not use plain water alone.

Warning: The temperature grades of a tire assume that it is properly
inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either sepa-
rately or in combination, can caus e heat buildup and possible tire fail-
ure.
