NOTICE
■To prevent damage to the engine and its components
●Do not let the indicator needle of the tachometer enter the red zone, which
indicates the maximum engine speed.
● The engine may be overheating if the high engine coolant temperature
warning light flashes or comes on. In this case, immediately stop the vehi-
cle in a safe place, and check the engine after it has cooled completely.

■Indicators
The indicators inform the driver of the operating state of the
vehicle’s various systems.
*1: These lights turn on when the engine switch is turned to the ON posi-
tion to indicate that a system check is being performed. They will turn
off after the engine is started, or after a few seconds. There may be a
malfunction in a system if a light does not come on, or if the lights do
not turn off. Have the vehicle inspected by your Scion dealer.

CAUTION
■When working on the engine compartment
●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, see a doctor.
■ When working near the electric cooling fan or radiator grille
Be sure the engine switch is in the LOCK position.
With the engine switch in the ON position, the electric cooling fan may \
auto-
matically start to run if the air condi tioning system is on and/or the coolant
temperature is high. ( P. 216)
■ 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
Driving with the air cleaner removed may cause excessive engine wear due
to dirt in the air.

5-1. Essential information
If you think something is wrong
If you notice any of the following symptoms, your vehicle probably
needs adjustment or repair. Cont act your Scion dealer as soon as
possible.
■ Visible symptoms
●Fluid leaks under the vehicle
(Water dripping from the air c onditioning system after use is
normal.)
● Flat-looking tires or uneven tire wear
● High engine coolant temperatur e warning light flashes or
comes on
● Low engine coolant temperature indicator comes on or does
not come on continuously
■ Audible symptoms
●Changes in exhaust sound
● Excessive tire squeal when cornering
● Strange noises related to the suspension system
● Pinging or other noises related to the engine
■ Operational symptoms
●Engine missing, stumbling or running rough
● Appreciable loss of power
● Vehicle pulls heavily to one side when braking
● Vehicle pulls heavily to one side when driving on a level road
● Loss of brake effectiveness, s pongy feeling, pedal almost
touches the floor

278 5-2. Steps to take in an emergency
Stop the vehicle immediately.The following warnings indicate the possibility of damage to the vehi-
cle that may lead to an accident. Immediately stop the vehicle in a
safe place and contact your Scion dealer.
Warning lightWarning light/Details
Charging system warning light Indicates a malfunction in the vehicle’s charging sys-
tem.
Low engine oil pressure warning light Indicates that the engine oil pressure is too low.
(Flashes or comes on) High engine coolant temperature warning light
Indicates the engine is almost overheating.

5-2. Steps to take in an emergency
Add coolant if necessary.
Water can be used in an emer-
gency if coolant is unavailable.
Start the engine and turn the
air 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 a nd 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 (especially a tie, a scarf or a muffler) away from
the fan and belts. Failure to do so may cause the hands or clothing to be
caught, resulting in serious injury.
● Do not loosen the radiator cap and 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.

324 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.

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.
