Pull our Prius on a dolly. Very first time taking off of dolly, every light on dash was on. A call to a very knowledgeable service manager said every thing was OK. Onboard computer said hey.. Rear wheels are going 60 miles an hour, but front wheels not turning???? Just turn on and drive around block, turn off, turn on. Guess computer learned, as has never happened again. Only thing is you need an extra set of yellow ramps to get loading angle so front air dam doesn't drag.
