ABSTRACT:
A method for indicating a running condition of a vehicle having an engine and a manual transmission generates a direction of an up-shift operation according to detected results of the throttle position, the gear position, the vehicle speed, and the engine load. The direction of the up-shift operation is basically generated when the throttle valve is open, a medium speed gear is engaged, and the vehicle speed is above a predetermined level. Besides, the generation of the direction of the up-shift operation is stopped when the load of the engine suitably detected by the pressure in the intake manifold is in a medium load range.
