Emission inspection and maintenance (I/M) programs

Some states have vehicle emission inspection programs which include OBD (On
Board Diagnostics) checks. The OBD system monitors the operation of the emis-
sion control system.

When 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
Lexus dealer to service the vehicle.

Situations your vehicle may not pass the I/M test

Your vehicle may not pass the I/M test in the following situations:

●

When the battery is disconnected or discharged
Readiness codes that are set during ordinary driving are erased. Also, depend-
ing 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 temporary 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.

When your vehicle does not pass the I/M test

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

Do-it-yourself service precautions

If you perform maintenance by yourself, be sure to follow the correct procedure as
given in the section for each part.

WARNING

The engine compartment contains many mechanisms and fluids that may move suddenly,
become hot, or become electrically charged. 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 battery. Fuel and
battery fumes are flammable.

●

Be extremely cautious when working on the battery. It contains poisonous and corro-
sive sulfuric acid.

■

When working near the electric cooling fan or radiator grille

Be sure the engine switch is OFF.
With the engine switch in ON, the electric cooling fan may automatically start to run if the
air conditioning is on or the coolant temperature is high.

■

Safety glasses

Wear safety glasses to prevent flying or falling material, fluid spray, etc., from getting in
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.
