Every time we leave our LR3 parked outside in winter (Milwaukee WI) we end up with 2 system faults "special systems not available": 1) for over head Rosen DVD inop and 2) for terrain response system. i understand the DVD not working when cold but terrain response?? gee there is a snow/ice setting and i suspect it might be cold when you have snow and ice, hey?? anyone have similar problems? we just had lr3 up at our cottage for weekend where we have no garage and the terrain response was inop all weekend due to being parked outside in cold.
