My sensors started to go off all the time, last year. Dealership replaced the Parking Sensor. $489 plus service. Afterward, I asked, "if they should be kept on all the time, like I was doing all this time, or only, if needed for parking?" Was told, "Makes no difference." Hate to think I have a bad habit, or was given vague advice from service rep. So, whats the verdict?

 

Ive had other brands of cars over the years with parking sensors that didn't have a switch like the LS to turn them on or off. They were always on. So I'd have to say that it shouldn't matter.
