4-2. Maintenance
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.
nIf 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.
nYour vehicle may not pass the I/M test in the following situations:
lWhen 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.
lWhen 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.
nWhen 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.
nIf your vehicle does not pass the I/M test
Contact your Lexus dealer to prepare the vehicle for re-testing.

Maintenance and care
nTire 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.
nEffects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
lReduced fuel efficiency
lReduced driving comfort and tire life
lReduced safety
lDamage to the drive train
If a tire needs frequent inflating, have it checked by your Lexus dealer.
nInstructions for checking tire pressure
When checking tire inflation pressure, observe the following:
lCheck only when the tires are cold.
If your vehicle has been parked for at least 3 hours and has not been driven for
more than 1 mile or 1.5 km, you will get an accurate cold tire inflation pressure
reading.
lAlways use a tire pressure gauge.
The appearance of the tire can be misleading. In addition, tire inflation pressures
that are even just a few pounds off can degrade ride and handling.
lDo not reduce tire inflation pressure after driving. It is normal for the tire infla-
tion pressure to be higher after driving.
lNever exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is bal-
anced.

position sensor, driver's seat belt buckle switch, front passenger occupant classifi-
cation system, “AIR BAG ON” indicator light, “AIR BAG OFF” indicator light, front

interconnecting wiring and power sources. ( →P. 1 0 9 )
nFront passenger detection sensor, passenger seat belt reminder and warning
buzzer
lIf luggage is placed on the front passenger seat, the front passenger detection
sensor may cause the warning light to flash and the warning buzzer to sound
even if a passenger is not sitting in the seat.
lIf a cushion is placed on the seat, the sensor may not detect a passenger, and the
warning light may not operate properly.
nElectric power steering system warning light
When the voltage is low or drops, the power steering warning light may come on.
nIf the malfunction indicator lamp comes on while driving
First check the following:
lIs the fuel tank empty?
If it is, fill the fuel tank immediately.
lIs the fuel tank cap loose?
If it is, tighten it securely.
The lamp will go off after several driving trips.
If the light does not go off even after several trips, contact your Lexus dealer as soon
as possible.
