A method of operating a vehicle, the vehicle comprising:an engine;a throttle operator being moveable by a driver of the vehicle;a throttle valve regulating airflow to the engine, a throttle valve position being based at least in part on the throttle operator position;a continuously variable transmission (CVT) operatively connected to the engine, the CVT including a driving pulley, a driven pulley, and a belt operatively connecting the driving pulley to the driven pulley;at least one ground engaging member operatively connected to the driven pulley and comprising at least one of: a wheel and a track;a piston operatively connected to the driving pulley for applying a piston force to the driving pulley when actuated and thereby changing an effective diameter of the driving pulley; anda control unit for controlling actuation of the piston and the piston force. The method further comprises: determining a driven pulley speed of the driven pulley; detecting an uphill stand condition indicative of the vehicle being stopped on an uphill; and, responsive to the detection of the uphill stand condition, controlling the piston force based on the driven pulley speed.
