Instrumentation Light is blinking: Engine misfire is occurring which could damage your catalytic converter. You should drive in a moderate fashion (avoid heavy acceleration and deceleration) and have your vehicle serviced at the first available opportunity. Under engine misfire conditions, excessive exhaust temperatures could damage the catalytic converter, the fuel system, interior floor coverings or other vehicle components, possibly causing a fire. Check fuel cap (if equipped) Momentarily illuminates when the CHECK ignition is turned to the ON position FUEL to ensure your bulb is working. CAP When this light turns on, check the fuel filler cap. Continuing to operate the vehicle with the check fuel cap light on, can activate the Service Engine Soon/Check Engine warning light. When the fuel filler cap is properly re-installed, the light(s) will turn off after a period of normal driving. This period will vary depending on driving conditions. It may take a long period of time for the system to detect an improperly installed fuel filler cap. For more information, refer to Fuel filler cap in the Maintenance and care chapter.
