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 moni-
tors the operation of th e 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 Toyota 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 se t 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 mal-
function 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
vehicle is driven 40 or more times.
■ If your vehicle does not pass the I/M test
Contact your Toyota dealer to prepare the vehicle for re-testing.

■Toyota does not recommen d gasoline containing MMT
Some gasoline contains octane enhancing additive called MMT (Methylcy-
clopentadienyl Manganese Tricarbonyl).
Toyota does not recommend the use of gasoline that contains MMT. If fuel
containing MMT is used, your emission control system may be adversely
affected.
The malfunction indicator lamp on the instrument cluster may come on. If
this happens, contact your Toyota dealer for service.
NOTICE
■ Notice on fuel quality
●Do not use improper fuels. If improper fuels are used the engine will be
damaged.
● Do not use leaded gasoline.
Leaded gasoline can cause damage to your vehicle’s catalytic converters
causing the emission control system to malfunction.
● Do not use gasohol other than that stated here.
Other gasohol may cause fuel system damage or vehicle performance
problems.
● Using unleaded gasoline with an octane number or rating lower than that
stated here will cause persistent heavy knocking.
At worst, this will lead to engine damage.
■ Fuel-related poor driveability
If after using a different type of fuel, poor driveability is encountered (poor
hot starting, vaporization, engine knocking, etc.), discontinue the use of that
type of fuel.
■ When refueling with gasohol
Take care not to spill gasohol. It can damage your vehicle's paint.
