Abstract
An alarm is emitted when a vehicle attempts to start when the speed ratio of a toroidal continuously variable transmission is small. A sensor (63. 67. 73) detects that the speed ratio is smaller than a predetermined range. A microprocessor (61) controls an alarm (68) to operate when an ignition switch (66) is in a position for starting an engine, while the speed ratio is smaller than the predetermined range.
