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 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 retailer 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 302. 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. 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. 200
