components contain or emit chemicals known to the State of California to
cause cancer and birth defects and other reproductive harm. Work in a
well ventilated area.

●

Oils, fuels and fluids contained in vehicles as well as waste produced by
component wear contain or emit chemicals known to the State of
California to cause cancer and birth defects or other reproductive harm.
Avoid exposure and wash any affected area immediately.

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. 231)

■

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 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.

●

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.
