Using this remote - control car is super easy. First, make sure the car and the controller are fully charged. Then, turn on the controller and the car, and they'll pair automatically. Use the controller's joysticks to move the car forward, backward, left, and right. When you're done playing, turn off both the car and the controller to save battery. As for maintenance, keep the car clean by using a soft cloth to wipe off dust. Don't expose it to water or extreme temperatures. If you notice any loose parts, fix them right away to keep the car in top shape.
