Malfunction Indicator Lamp MALFUNCTION INDICATOR LAMP On V6 and 4-cylinder ULEV This indicator should light when the ignition switch is ON (II), and go out after the engine starts. If it comes on at any other time, it indicates one of the engine's emissions control systems may have a problem. Even though you may feel no difference in your car's performance, it can reduce your fuel economy and cause your car to put out excessive emissions. Continued operation may cause serious damage. If you have recently refueled your car, the cause of this indicator coming on could be a loose or missing fuel fill cap. Check the cap and tighten it until it clicks several times. Replace the fuel fill cap if it is missing. Tightening the cap will not make the indicator turn off immediately; it takes at least three driving trips. If the indicator remains on past three driving trips, or the fuel cap was not loose or missing, have the car checked by the dealer as soon as possible. Drive moderately until the dealer has inspected the problem. Avoid full-throttle acceleration and driving at high speed. You should also have the dealer inspect your car if this indicator comes on repeatedly, even though it may turn off as you continue driving.

If it comes on at any other time, it indicates one of the engine's emissions control systems may have a problem. Even though you may feel no difference in your car's performance, it can reduce your fuel economy and cause your car to put out excessive emissions. Continued operation may cause serious damage. If you keep driving with the malf unction indicator lamp on, you can damage your car's emissions controls and engine. Those repairs may not be covered by your car's warranties.
