72 UNDERSTANDING YOUR INSTRUMENT PANEL 16. Malfunction Indicator Light This light is part of an onboard diagnostic system called OBD that monitors engine control systems. The light will be illuminated when the key is in the ON/RUN position before engine start. If the bulb does not come on when turning the key from OFF to ON/RUN, have the condition checked promptly. Certain conditions such as a loose or missing gas cap, poor fuel quality, etc., may illuminate the light after engine start. The vehicle should be serviced if the light stays on through several of your typical driving cycles. In most situations, the vehicle will drive normally and will not require towing. If the Malfunction Indicator Light flashes when the engine is running, serious conditions may exist that could lead to immediate loss of power or severe catalytic converter damage. The vehicle should be serviced as soon as possible if this occurs. 17. Odometer/Trip Odometer Reset Knob Press this knob to switch between the odometer and trip odometer. While the trip odometer is being displayed, press and hold this knob for a few seconds to reset the trip odometer to zero miles/kilometers. 18. Odometer/Trip Odometer Shows the total distance the vehicle has been driven. U.S. Federal regulations require that upon transfer of vehicle ownership, the seller certify to the purchaser the correct mileage that the vehicle has been driven. Therefore, if the odometer reading changes during repair or replacement, be sure to keep a record of the reading before and after the service so the correct mileage can be determined. 19. Door Ajar Indicator This vacuum fluorescent indicator illuminates when a door is not completely closed. If the door is open for more than 8 minutes and the ignition key is in the OFF position, the indicator will turn off.
