Using these Hot Wheels Monster Trucks is super easy. First, turn on the trucks and the remote controls. The 2.4 GHz frequency means you can play with both trucks at once without any issues. Simply use the remote to move the trucks forward, backward, left, and right. For some extra fun, prop a truck on its back tires and watch it drive on two wheels. You can also use the included ramp to launch the trucks into stunts or onto the crushable cars. When it comes to maintenance, keep the trucks clean. After playing on dirty or rough terrains, gently wipe them down with a soft cloth. Make sure to use the right batteries for the trucks and the remote controls. Keep small parts away from very young children as they could be a choking hazard. Also, don't let the trucks run out of battery for long periods as it may damage the battery. Have a blast playing with these awesome Monster Trucks!
