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.
If the Light Is On Steady
You 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 352.
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.
