The temperature has dropped over the last few days and I find the Juke is struggling to cope. Below about -20C the heated rear window does not clear completely. The heating struggles to keep the side windows clear at the front. The side windows at the rear always have ice on them, so I assume passengers sitting in the rear seats would be cold. The temperature for the driver and front passenger is OK, barely, but this is with the heating on full. I don't know what it will be like when the real winter comes. Even my wife's car, a soft top, copes with cold weather better than this. The only thing that does seem up to the job is the seat heating, which is plenty warm enough.
