Note: this vehicle requires four AA batteries, two of which are used for the remote control and two for the car. How to install the car battery: First, observe the cross design on the back of the car. Press the top body shell and gently push it backwards to open the entire top body shell while lifting the top body shell. Then install the battery. This remote control mini car is exquisite in workmanship, rich in colors, and varied in styles. The design of the four directions, left, right, front, and rear, makes it easy for children aged 3 to 7 to master the remote control. The remote control distance is about 20 meters, the design of large-wheeled off-road vehicles, and the experience of high-speed racing, both indoors and outdoors, provide more fun for children. PRECAUTIONS: DANGER OF DROWNING - small parts, not for children under 3 years old.
