Thanks Jonathan. I had no problems up in KS when the temp dropped to single digits. I did allow extra time for the glow plug. Mine is remote start, so the computer is smart enough to figure it all out.I live in CT and haven't had a problem starting up, as long as your battery's charged you should be fine. On really cold days sometimes I let it glow twice, by turning the key almost all the way but without ignition. If you're going reeeaaaally far north, you may want some fuel additive to prevent gelling, but I haven't had experience with that myself.
