Using this Maisto Tech RC Porsche Taycan Turbo S is easy. First, make sure the built - in lithium battery in the car and the two AAA batteries in the pistol controller are properly installed. Then, use the included USB cable to charge the car for about 45 minutes. Once charged, turn on both the car and the controller. You can now control the car within a range of 115 ft. (35 meters). Up to 4 players can have fun together at the same time. When not in use, store the car in a dry place. Avoid exposing it to extreme temperatures. If the car gets dirty, you can gently wipe it with a soft cloth. Remember, this car is suitable for kids aged 5 and up, so adult supervision is recommended for younger users.
