If The Light Is Flashing; If The Light Is On Steady - Chevrolet 2006 Epica Owner's Manual

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 5-3.
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.

If the Light Is Flashing

The following may prevent more serious damage to
your vehicle:
•
Reducing vehicle speed
•
Avoiding hard accelerations
•
Avoiding steep uphill grades
If the light stops flashing and remains on steady,
see "If the Light Is On Steady" following.
If the light continues to flash, when it is safe to do
so, stop the vehicle. Find a safe place to park your
vehicle. Turn the key off, wait at least 10 seconds
and restart the engine. If the light remains on steady,
see "If the Light Is On Steady" following. If the light
is still flashing, follow the previous steps, and see
your dealer for service as soon as possible.

If the Light Is On Steady

You also may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install the
cap. See Filling the Tank on page 5-8. The diagnostic
system can determine if the fuel cap has been left off or
improperly installed. A loose or missing fuel cap will allow
fuel to evaporate into the atmosphere. A few driving trips
with the cap properly installed should turn the light off.
