Tilt the cab roof forward to place the Chase race car into the driver’s seat, before pushing the patroller forward on six real working wheels. Then, when it’s time for a high-speed rescue, remove Chase from the Cab, close the roof, then put Chase on top of the cab to engage the transformation, which pops the trailer's roof open to convert it into a launch ramp, and lowers the side walls to reveal a staging area and additional vehicle storage space! When playtime is over, fold the ramp and raise the walls to return into truck-mode, so you can pack up your toy car in the patroller, then take them with you anywhere, for exciting action on the go!
