A method for controlling an engine of a vehicle going downhill with a throttle operator in an idle position, and a driven pulley of a CVT initially having a driven pulley speed below a predetermined driven pulley speed, includes: determining a first speed, the first speed being proportional to the driven pulley speed; as the driven pulley speed increases and the driven pulley speed is below the predetermined driven pulley speed, increasing an actual engine speed as the driven pulley speed increases; the actual engine speed being an engagement speed when the driven pulley speed is the predetermined driven pulley speed; and as the driven pulley speed continues to increase and the driven pulley speed is above the predetermined driven pulley speed: controlling the engine to operate under conditions corresponding to an engine braking speed thereby causing engine braking, the engine braking speed being less than the actual engine speed.
