Getting Ready for Cold Weather Make sure you have a sturdy ice scrapper and snowbrush. Because cold weather reduces tire pressure, check them more often.
Cold weather affects battery efficiency.
Most cold-weather breakdowns occur because batteries are not delivering full cranking power. Make sure your battery is fully charged and the battery cables are free of corrosion. In severe winter temperatures, you may need to change the grade of your engine oil. See you Owner's Manual for the winter oil viscosity grade recommended for your vehicle's engine. Use snow tires if you live in or travel through snow belts.
