Maintenance and care
COROLLA_TMMMS_TMMC_U (OM02494U)
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.
●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 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 vehi-
cle is driven 40 or more times.
Contact your Toyota dealer to prepare the vehicle for re-testing.
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 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 sev-
eral driving trips
If your vehicle does not pass the I/M test
5549-1. Specifications
COROLLA_TMMMS_TMMC_U (OM02494U)■Non-recommendation of the use of gasoline containing MMT
Some gasoline contains an 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.
■If your engine knocks
●Consult your Toyota dealer.
●You may occasionally notice light knocking for a short time while accelerat-
ing or driving uphill. This is normal and there is no need for concern.
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 three-way catalytic
converters causing the emission control system to malfunction.
●Do not use gasohol other than the type previously stated.
Other gasohol may cause fuel system damage or vehicle performance
problems.
●Using unleaded gasoline with an octane number or rating lower than the
level previously stated will cause persistent heavy knocking.
At worst, this will lead to engine damage.
■Fuel-related poor driveability
If poor driveability (poor hot starting, vaporization, engine knocking, etc.) is
encountered after using a different type of fuel, 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.
