engine might not run as smoothly. This could
lead to costly repairs that might not be
covered by your warranty.
Notice: Modifications made to the engine,
transaxle, exhaust, intake, or fuel system
of your vehicle or replacement tires that do not
match your vehicle's original tires can affect
your vehicle's emission controls and may
cause this light to come on. Modifications to
these systems could lead to costly repairs not
covered by your warranty. This may also
result in a failure to pass a required Emission
Inspection/Maintenance test. See Accessories
and Modifications on page 264.
When the ignition is on, this light should come on
and should go out after a few seconds as a
check to show you it is working. If the light does
not come on, have it repaired.
This light will also come on during a malfunction in
one of two ways:
•
Light Flashing — A misfire condition has
been detected. A misfire increases vehicle
emissions and may damage the emission
control system on your vehicle. Diagnosis and
service may be required.
•
Light On Steady — An emission control
system malfunction has been detected on your
vehicle. Diagnosis and service may be
required.
