Using the product is super easy! First, put your Hot Wheels car on the manual elevator and push it to the top of the parking garage. Then release the car down the ramp. As it goes through each level, there are three random activators. You never know when they'll trigger the shark to break through and try to eat your car. Your goal is to get the car to the end of the track. When you do, the shark gets locked in a cage, and you can drive the track without the shark attacking. You can use the one Hot Wheels vehicle that comes with the set, or add your own (you'll need to buy additional vehicles separately). You can also connect this set to other Hot Wheels sets and track pieces to make a really cool city. Just remember, the colors and decorations on the set might be a bit different from what you see in the picture. When it comes to maintenance, keep the set clean. You can use a dry cloth to wipe off any dust. If you have any small parts, make sure to keep them in a safe place so you don't lose them. And have a lot of fun with your Hot Wheels adventures!
