What are the three red and yellow lights on the ceiling?
There are three lights that come on briefly when the vehicle is in reverse.
That is your back up warning system...as you back closer to an object the first yellow light comes on, then the second and finally ....just before you back into the object the red light comes on. you can experiment....back toward a solid object until the second light comes on .....stop the car, put it in park , get out and see how close you are to the object.
My warning stays on red
GuruVPNMX..... your warning is broke
