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 Your Tank” in the Index. 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.

Did you just drive through a deep puddle of water?

If so, your electrical system may be wet. The condition

will usually be corrected when the electrical system

dries out. A few driving trips should turn the light off.

Have you recently changed brands of fuel?

If so, be sure to fuel your vehicle with quality fuel. See

“Fuel” in the Index. Poor fuel quality will cause your

engine not to run as efficiently as designed. You may

notice this as stalling after start

-up, stalling when you put

the vehicle into gear, misfiring, hesitation on acceleration

or stumbling on acceleration. (These conditions may go

away once the engine is warmed up.) This will be detected

by the system and cause the light to turn on.

If you experience one or more of these conditions,

change the fuel brand you use. It will require at least

one full tank of the proper fuel to turn the light off.

If none of the above steps have made the light turn off,

have your dealer or qualified service center check the

vehicle. Your dealer has the proper test equipment and

diagnostic tools to fix any mechanical or electrical

problems that may have developed.
