186 UNDERSTANDING YOUR INSTRUMENT PANEL 27. Malfunction Indicator Light (MIL) The Malfunction Indicator Light (MIL) is part of an onboard diagnostic system, called OBD, that monitors engine and automatic transmission control systems. The light will illuminate when the key is in the ON position, before engine start. If the bulb does not come on when turning the key from OFF to ON, have the condition checked promptly. Certain conditions such as a loose or missing gas cap, poor fuel quality, etc., may illuminate the MIL 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 MIL 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. 28. Cruise Indicator - If Equipped This indicator lights when the electronic speed control system is turned on. 29. Odometer/Trip Odometer Reset Button Press this button to change the display from odometer to either of the two trip odometer settings. When the trip odometer is displayed, press once for Trip A, and press again for Trip B. If the instrument cluster is a base cluster (no separate compass/temperature display), press the button a third time for outside ambient temperature on the odometer display. Press and hold the button for two seconds to reset the trip odometer to 0 miles (0 km). The odometer must be in trip mode to reset. Press this button to view the compass display (if equipped). Refer to "Compass/Trip Computer" in this section.
