General maintenance should be pe rformed on a daily basis. This can
be done by yourself or by a Lexus dealer.

Guide”, “Warranty and Service Guide” , “Owner’s Manual Supplement” or

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.
