You turn the key to start. The engine then shakes and judders by itself and then you chose a car by clicking on the right arrow and then start. In the race, when the lights go out you hold the up arrow until the rev counter is in the red. you then take your finger off the up arrow and press the right arrow, before holding the up arrow again. If you are confused, there are clearer instructions in the game.
