yesterday in the am, we got a little snow, as i started backing out of my driveway, the sensor sound was continuous, i think the sensor is so sensitive, the waves reflected off the snow and set it off as if i was going to hit something large...there was only about 1 inch of snow on the ground. strange huh?

 

when I took my delivery yesterday, my MA told me about the backup sensor. He mentioned that sometimes it will continuously beep if it's snowing, probably because the sensors on the rear bumper are covered by snow or something else. That makes sense to me.
