Abstract
A temperature warning method of a friction element for issuing a warning depending on temperature of the friction element arranged between a power source and a driving wheel, includes issuing the warning when the temperature of the friction element exceeds an upper limit temperature, and making a period of time, from when the temperature of the friction element exceeds the upper limit temperature until when the warning is issued, longer when the temperature of the friction element exceeds the upper limit temperature for a first time than when the temperature of the friction element exceeds the upper limit temperature for a second or subsequent time.
