My 2002 Sonata, which I have been VERY happy with, just had its first\nhiccup.\n\nWe had been driving around with it all Friday evening. On Saturday we\ngot up to snow (I live in NJ outside Philly and we got quite a bit of\nthe white stuff). The car seemed okay but just wouldn't start.\n\nI had to jump it from the other car and now it seems to be fine.\n\nI can guess that perhaps we left a door open but I didn't think so.\n\nThe key question is, are the standard batteries not that great? Should\nI take the car in for service now? Should I just get a better grade\nbattery and forego the warranty?\n\nFinally, anyone know how to get the climate control system back from\nCelsius settings to Farenheit?
