4-2. Maintenance
■Allow inspection and repairs to be performed by a Lexus dealer
●Lexus technicians are well-trained specialists and are kept up to date with the
latest service information. They are well informed about the operations of all
systems on your vehicle.
●Keep a copy of the repair order. It proves that the maintenance that has been
performed is under warranty coverage. If any problem should arise while your
vehicle is under warranty, your Lexus dealer will promptly take care of it.
CAUTION
■Hazardous materials
●Engine exhaust, some of its constituents, and a wide variety of automobile com-
ponents contain or emit chemicals known to the State of California to cause can-
cer 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 compo-
nent 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.
●Battery posts, terminals and related accessories contain lead and lead com-
pounds which are known to cause brain damage. Wash your hands after han-
dling. (→P. 3 3 3 )
●Used engine oil contains chemicals that have been shown to cause cancer in lab-
oratory animals. Avoid prolonged and repeated contact. Always protect your

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 oper-
ation 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. Cont act 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 du ring 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 mal-
function and your vehicle may not pass the I/M test.
■ When the malfunction indicator la mp goes off after several driv-
ing 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 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.
■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, inverter, 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 or 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
corrosive sulfuric acid.
■When working near the electric cooling fan or radiator grille
Be sure the engine switch is in “LOCK”.
With the engine switch is in the “ACC” or “ON” position, the electric cooling fan
may automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. (→P. 3 2 9 )
■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 filter
Driving with the air cleaner filter removed may cause excessive engine wear due to
dirt in the air. Also a backfire could cause a fire in the engine compartment.
