Emission inspection and
maintenance (I/M) programs
The OBD system determines that a problem exists somewhere in the emission
control system. Your vehicle may not pa ss the I/M test and may need to be
repaired. Contact your Lexus dealer to service the vehicle.
●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 com-
pletely 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.
The error code in the OBD system will not be cleared unless the vehicle is driven
40 or more times.
Contact your Lexus dealer to prepare the vehicle for re-testing.
Some states have vehicle emission inspection programs which include OBD
(On Board Diagnostics) checks. The OBD system monitors the operation of
the emission control system.

Maintenance and care
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 or rags, in the engine com-
partment.
●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 fans or radiator grille
Be sure the engine switch is off. With the engine switch in IGNITION ON mode, the
electric cooling fans may automatically start to run if the air conditioning is on and/or
the coolant temperature is high. ( P. 461)
■When working on or under the vehicle
Do not get under the vehicle with just the jack supporting it.
Always use automotive jack stands or other solid supports.
■Safety glasses
Wear safety glasses to prevent flying or fallin g 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.

Maintenance and care
■Tire inflation pressure check interval
You should check tire inflation pressure every two weeks, or at least once a month. Do
not forget to check the spare.
■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
●Reduced fuel efficiency
●Reduced driving comfort and tire life
●Reduced safety
●Damage to the drive train
If a tire needs frequent inflating, have it checked by your Lexus dealer.
■Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
●Check only when the tires are cold.
If your vehicle has been parked for at le ast 3 hours and has not been driven for more
than 1 mile or 1.5 km, you will get an accur ate cold tire inflation pressure reading.
●Always use a tire pressure gauge.
The appearance of the tire can be misleading. In addition, tire inflation pressure that is
even just a few pounds off can affect ride quality and handling.
●Do not reduce tire inflation pressure after driv ing. It is normal for tire inflation pressure
to be higher after driving.
●Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is balanced.

Fuel pump shut off system
Follow the procedure below to restart the engine after the system is activated.
Turn the engine switch to AC CESSORY mode or turn it off.
Restart the engine.
To minimize the risk of fuel leakage wh en the engine stalls or when an airbag
inflates upon collision, the fuel pump shut off system stops the supply of fuel to
the engine.

■Before starting the engine
Inspect the ground under the vehicle.
If you find that fuel has leaked onto the ground, the fuel system has been damaged and
is in need of repair. Do not restart the engine.
