To use the Hot Wheels RC Barbie SUV, first, make sure the batteries are properly installed in both the vehicle and the remote control. Then, place your two full - size Barbie dolls inside the SUV. You can use the rear storage to keep their accessories. Use the remote control to drive the SUV indoors or outdoors for exciting adventures. When you want to customize it, use the sticker sheet provided. Remember, dolls and accessories are sold separately. For maintenance, keep the SUV clean by using a dry cloth. Avoid getting it wet as it may damage the electronic components. Also, store the vehicle in a cool, dry place when not in use. And since it's for ages 4 and up, adult supervision is recommended to ensure safe play.
