6-2. Maintenance
Emission inspection and maintenance (I/M)
programs
The OBD system determines that a problem exists somewhere in the
emission control system. Your vehicl e may not pass 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 dur ing ordinary driving are erased.
Also, depending on your driving ha bits, the readiness codes may not be
completely set.
●When the fuel tank cap is loose
The malfunction indicator lamp co mes on indicating a temporary mal-
function and your vehicle may not pass the I/M test.
The error code in the OBD system will no t 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 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
Your vehicle may not pass the I/M test in the following situations:
When the malfunction indicator lamp still remains on after several
driving trips
If your vehicle does not pass the I/M test

Maintenance and care
Ti r e v a l v e
Tire pressure gauge
Remove the tire valve cap.
Press the tip of the tire pressure gauge onto the tire valve.
Read the pressure using the gauge gradations.
If the tire inflation pressure is not at the recommended level, adjust the
pressure.
If you add too much air, press the center of the valve to deflate.
After completing the tire inflation pressure measurement and adjust-
ment, apply soapy water to the valve and check for leakage.
Put the tire valve cap back on.
■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.

First check the following:
●Is the fuel tank empty?
If it is, fill the fuel tank immediately.
●Is the fuel tank cap loose?
If it is, tighten it securely.
The light will go off after several driving trips.
If the light does not go off even after several trips, contact your Lexus dealer as soon

■Electric power steering system warning light (warning buzzer)
When the 12-volt battery charge becomes insufficient or the voltage temporarily
drops, the electric power steering system warning light may come on and the warn-
ing buzzer may sound.
■When the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level. Pushing the tire
pressure warning reset switch will not turn off the tire pressure warning light.
