Using this Carrera Go slot racing system is easy. First, set up the 5.4 - meter racetrack according to your preference. Place the police car and the yellow sports car on the track. Connect the transformer to power up the system. Each player can hold a controller and start racing. Press the turbo button on the controller when you want to speed up, especially when going through the looping or fly - over. As for the lap counter, it will keep track of how many laps you've completed. When you're done playing, carefully put away all the parts in a safe place. Keep the cars and the track clean by using a soft cloth. Avoid getting the electronic parts wet. If you notice any loose parts, make sure to fix them before the next play session.
