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.
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 330
.
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.
