In one embodiment, sensor 160 provides an indication of a temperature of the air within the interior of the respective CVT unit 122, air intake system 124, and exhaust system 126 to an engine control module 162 which includes logic to control the operation of power source 106. When a monitored air temperature exceeds a threshold amount, engine control module 162 responds by at least one of limiting an output speed of output shaft 120 of power source 106, limiting a speed of vehicle 100, and indicating an overheat condition to an operator of vehicle 100 through a gauge 164 within an operator area of vehicle 100. Exemplary indicators of an overheat condition include a light, a warning message on a display, and other suitable ways of communicating a condition to an operator. By limiting an engine speed or a vehicle speed, the temperature of the air in an interior of CVT unit 122 is reduced and a temperature of a drive belt in the interior of CVT unit 122 is reduced. This reduces the risk of a drive belt failure.
