4-2. Maintenance
Emission inspection and maintenance (I/M) programs
Some states have vehicle emission in spection programs which include OBD
(On Board Diagnostics) checks. The OBD system monitors 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 Lexus dealer to service the
vehicle.
■ Your vehicle may not pass the I/M test:
●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 as a temporary malfunc-
tion and your vehicle may not pass the I/M test.
■ When the malfunction indicator lamp goes off after several driving
trips
The error code in the OBD system will not be cleared unless the vehi-
cle is driven 40 or more times.
■ If your vehicle does not pass the I/M test
Contact your Lexus dealer to prepare the vehicle for re-testing.

Maintenance and care
CAUTION
The engine compartment contains many mechanisms and fluids that may move sud-
denly, 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, 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 or rags, in the engine
compartment.
●Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes are flam-
mable.
■When working near the electric cooling fan
Be sure the ignition switch is in the “LOCK” position.
With the ignition on, the electric cooling fan may automatically start to run if the air
conditioning is on. ( P. 2 6 1 )
■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 filters
Driving with the air cleaner filters remo ved may cause excessive engine wear due
to dirt in the air. Also a backfire could cause a fire in the engine compartment.
