This light comes on, as a check to show it is working,

when the ignition is turned ON/RUN but the engine is not

running. If the light does not come on, have it repaired.

This light also comes on during a malfunction in

one of two ways:

• Light Flashing — A misﬁre condition has been

detected. A misﬁre increases vehicle emissions and

could damage the emission control system on your

vehicle. Diagnosis and service might be required.

• Light On Steady — An emission control system

malfunction has been detected on your vehicle.

Diagnosis and service might be required.

If the Light is Flashing

The following can prevent more serious damage to

your vehicle:

• Reduce vehicle speed.

• Avoid hard accelerations.

• Avoid 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 the vehicle.

Turn the ignition 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/retailer

for service as soon as possible.

If the Light Is On Steady

You might 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 allows fuel to evaporate into the atmosphere.

A few driving trips with the cap properly installed should

turn the light off.

Did you just drive through a deep puddle of water?

If so, your vehicle’s electrical system might be wet.

The condition is usually corrected when the electrical

system dries out. A few driving trips should turn the

light off.
