72 Instrument Cluster Fasten Safety belt It will illuminate and a chime will sound to remind you to fasten your safety belt. High Beam It will illuminate when the headlamp high beam is switched on. It will flash when you use the headlamp flasher. Low Fuel Level It will illuminate when the fuel level is low or near empty. Refuel as soon as possible. Low Tire Pressure Warning It will illuminate when your tire pressure is low. If the lamp remains on with the engine running or when driving, check your tire pressure as soon as possible. The lamp also illuminates momentarily when you switch the ignition on to confirm the lamp is functional. If it does not illuminate when you switch the ignition on, or begins to flash at any time, have the system checked by your authorized dealer. Overdrive Off (if equipped) It will illuminate when the overdrive function of the transmission has been turned off. If the light does not illuminate, have the transmission serviced soon, or damage may occur. Powertrain Malfunction/Electronic Throttle Control It will illuminate when a powertrain fault has been detected. Contact your authorized dealer as soon as possible. Service Engine Soon The service engine soon indicator light illuminates when the ignition is first turned to the on position to check the bulb and to indicate whether the vehicle is ready for Inspection/ Maintenance (I/M) testing. Normally, the "service engine soon" light will stay on until the engine is cranked, then turn itself off if no malfunctions are present. However, if after 15 seconds the "service engine soon" light blinks eight times, it means that the vehicle is not ready for I/M testing. See the Readiness for inspection/maintenance (I/M) testing in the Fuel and Refueling chapter.
