If the Light Is Flashing, If the Light Is On Steady | Buick 2000

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 doesn't come on, have it repaired.

This light will also come on during a malfunction in one of two ways:

DLight Flashing --A misfire condition has been detected. A misfire increases vehicle emissions and may damage the emission control system on your vehicle. Dealer or qualified service center diagnosis and service may be required.

DLight On Steady --An emission control system malfunction has been detected on your vehicle. Dealer or qualified service center diagnosis and service may be required.

If the Light Is Flashing

The following may prevent more serious damage to your vehicle:

DReducing vehicle speed.

DAvoiding hard accelerations.

DAvoiding steep uphill grades.

DIf you are towing a trailer, reduce the amount of cargo being hauled as soon as it is possible.

yellow blue

If the light stops flashing and remains on steady, see ªIf the Light Is On Steadyº 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 ªIf the Light Is On Steadyº following. If the light is still flashing, follow the previous steps, and drive the vehicle to your dealer or qualified service center for service.

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 ªFilling Your Tankº 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.
