If The Light Is Flashing - Pontiac 2007 G5 Owner's Manual

This light should come on, as a check to show you it
is working, when the ignition is on and the engine is
not running. 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 you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible
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.
