I Drove about 60 miles in heavy wet snow last evening. After about 20 miles I got the warning message that the auto braking system and smart cruise control were disabled. I thought that the normal cruise control would still work, but could not figure out how to turn it on. The other thing I noticed was ice building up on the led headlights distorting the light beam. It was about 32 degrees F. I suspect that if the headlights were incandescent, there would have been enough heat to keep the headlights clear. It was the worst snow conditions I have driven in for a long, I thought the Clarity handled very well. Does anyone know how to get the standard cruise control working when the radar unit is Wblocked?
