This may prevent more serious damage to your
vehicle. This system is also designed to assist your
service technician in correctly diagnosing any
malfunction.
Notice: If you keep driving your vehicle with
this light on, after awhile, your emission
controls may not work as well, your fuel
economy may not be as good, and your engine
may not run as smoothly. This could lead to
costly repairs that may 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.
