Emission inspection and maintenance (I/M) programs

Some states have vehicle emission inspection programs which

include OBD (On Board Diagnostics) checks. The OBD system moni-

tors the operation of the emission control system.

■

If the malfunction indicator lamp comes on

The OBD system determines that a problem exists somewhere
in the emission control system. Your vehicle may not pass the I/
M test and may need to be repaired. Contact your Scion dealer
to service the vehicle.

■

Your vehicle may not pass the I/M test in the following situa-
tions:
● When the battery is disconnected or discharged

Readiness codes that are set during ordinary driving are
erased.
Also, depending on your driving habits, the readiness codes
may not be completely set.

● When the fuel tank cap is loose

The malfunction indicator lamp comes on indicating a tempo-
rary malfunction and your vehicle may not pass the I/M test.

■

When the malfunction indicator lamp still remains on after
several driving trips

The error code in the OBD system will not be cleared unless the
vehicle is driven 40 or more times.

■

If your vehicle does not pass the I/M test

Contact your Scion dealer to prepare the vehicle for re-testing.

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.

■

When working near the electric cooling fans or radiator grille

Be sure the engine switch is off.
With the ignition on, the electric cooling fans may automatically start to run if
the air conditioning is on and/or the coolant temperature is high. (

P. 245)

■

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.

CAUTION

■

Pre-driving check

Check that the hood is fully closed and locked.
If the hood is not locked properly, it may open while the vehicle is in motion
and cause an accident, which may result in death or serious injury.

■

After installing the support rod into the slot

Make sure the rod supports the hood securely from falling down on to your
head or body.

NOTICE

■

When closing the hood

Be sure to return the support rod to its clip before closing the hood. Closing
the hood without returning the support rod properly could cause the hood to
bend.

■

When raising your vehicle

Make sure to observe the following precautions to reduce the possibility of
death or serious injury.

●

When using a floor jack, follow the instructions of the manual provided with
the jack.

●

Do not use the jack that was supplied with your vehicle.

●

Do not put any part of your body underneath the vehicle when it is sup-
ported only by the floor jack.

●

Always use floor jack and/or automotive jack stands on a solid, flat, level
surface.

●

Do not start the engine while the vehicle is supported by the floor jack.

●

Stop the vehicle on level, firm ground, firmly set the parking brake and shift
the shift lever in P (automatic transmission) or R (manual transmission).

●

Make sure to set the floor jack properly at the jack point.
Raising the vehicle with an improperly positioned floor jack will damage
the vehicle and may cause the vehicle to fall off the floor jack.

●

Do not raise the vehicle while someone is in the vehicle.

●

When raising the vehicle, do not place any objects on top of or underneath
the floor jack.

●

Lift up the vehicle using a floor jack
such as the one shown in the illustra-
tion.

Engine oil

With the engine at operating temperature and turned off, check the oil
level on the dipstick.

■

Checking the engine oil

Park the vehicle on level ground. After warming up the engine
and turning it off, wait more than 5 minutes for the oil to drain
back into the bottom of the engine.

Holding a rag under the end, pull
the dipstick out.

Wipe the dipstick clean.

Flat dipstick: Reinsert the dipstick fully.

Non-flat dipstick: Reinsert the
non-flat dipstick fully with its pro-
truding areas (

 in the illustra-

tion) pointing towards the
engine.

Engine oil consumption

A certain amount of engine oil will be consumed while driving. In the follow-
ing situations, oil consumption may increase, and engine oil may need to be
refilled in between oil maintenance intervals.

●

When the engine is new, for example directly after purchasing the vehicle
or after replacing the engine

●

If low quality oil or oil of an inappropriate viscosity is used

●

When driving at high engine speeds or with a heavy load, or when driving
while accelerating or decelerating frequently

●

When leaving the engine idling for a long time, or when driving frequently
through heavy traffic

CAUTION

■

Used engine oil

●

Used engine oil contains potentially harmful contaminants which may
cause skin disorders such as inflammation and skin cancer, so care
should be taken to avoid prolonged and repeated contact. To remove used
engine oil from your skin, wash thoroughly with soap and water.

●

Dispose of used oil and filters only in a safe and acceptable manner. Do
not dispose of used oil and filters in household trash, in sewers or onto the
ground. Call your Scion dealer, service station or auto parts store for infor-
mation concerning recycling or disposal.

●

Do not leave used engine oil within the reach of children.

Engine coolant

The coolant level is satisfactory if it is between the “F” and “L” lines on
the reservoir when the engine is cold.

Reservoir cap

Full

Low

If the level is on or below the “L”
line, add coolant up to the “F” line.
(

P. 341)

■

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.

CAUTION

■

When the engine is hot

Do not remove the radiator cap. 
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.

NOTICE

■

When adding coolant

Coolant is neither plain water nor straight 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 damaging parts or paint.
