UP-Shift Indicator Lamp

The upshift indicator lamp is located in the instrument panel cluster assembly and is controlled by the powertrain control module. The purpose of the upshift indicator is to provide a display that indicates to the driver when to upshift the manual transaxle for optimum fuel economy. The powertrain control module determines the optimal upshift point based on engine speed and load. The upshift indicator lamp will not be operational under any of the following conditions:
^ The vehicle's speed is less than 5 km/h (3 MPH).
^ The engine is idling or the engine is running under a heavy load.
^ The engine's speed is less than 1500 RPM.
