A method of protecting the high voltage DC bus of a hybrid vehicle as well as to a hybrid vehicle and controller configured to implement the method. The method involves detecting a plurality of requests to start the vehicle and, in response to at least the first request, precharging and energizing the high voltage DC bus without starting the engine. When one or more further requests are detected the engine is started and the high voltage DC bus is energized if each of the further requests is detected within a respective predetermined time interval from the preceding request. Starting the engine provides an audible feedback to the driver that the vehicle is ready for operation, thereby preventing overheating of the precharging circuit.
