Using this Carrera GO! PAW Patrol battery set is easy. First, make sure the batteries are properly installed in the cars. Then, place the track pieces together to form the 14.10 ft. long track. Put Chase and Rubble's cars on the track and let the race begin. When playing, keep the track on a flat surface to prevent the cars from falling off. Avoid rough handling of the cars as it may damage them. After each play session, store the cars and track pieces in a safe place. Occasionally, clean the cars and track with a soft, dry cloth to keep them in good condition.
