Abstract

A method for indicating a shift operation for a manual transmission gear includes a step for comparing a detected vehicle speed with a reference speed which is determined and changed on the basis of a detected engine temperature and a step for indicating the shift operation on this basis of a result of the comparison. When a temperature parameter relating to the engine operation is lower than a predetermined reference temperature value, the reference vehicle speed is raised so that the indication of the shift operation will not be generated.
