Talking Car

Queen Munchkin here; This morning I made the car talk. I was laying in Bobs' lap and when I jumped down my paw hit the button on his keys to make the car start talking. He pulled it out and started pushing the button over and over trying to get it to stop, but it took him about 6 tries. Now if I can just figure out what; "Beep, beep, beep, beep, beep!" means?
