Winter can take a toll on your battery and other parts of the car. Make sure your battery is fully powered and functioning properly. You should also check your other key components, everything works harder in the winter when it gets colder. Have your tires, brakes and radiator checked. You should also check your oil, coolant, windshield washer and other vital fluids. Have them inspect fluids, hoses, belts and windshield wiper blades.
Last thing you want is to be stranded and cold in the winter. Carry a blanket and water just in case.
