- Battery – Cold weather is hard on batteries, so it’s wise to check the battery and charging system for optimum performance. Because batteries don’t always give warning signs before they fail, it is advisable to replace batteries that are more than three years old.
- Antifreeze – Antifreeze (coolant) should be flushed and refilled at least every two years in most vehicles. As a reminder, do not add 100 percent antifreeze as full-strength antifreeze actually has a lower freeze point than when mixed with water.
- Brakes – Have the brake system checked. Brakes are critical to vehicle safety and particularly important when driving on icy or snow-covered roads.
- Tires – Check the tire tread depth and tire pressure, including the spare. If snow and ice are a problem in your area, consider special tires designed to grip slick roads. During winter, tire pressure should be checked weekly as tires lose pressure when temperatures drop.
- Oil – Be diligent about changing the oil at recommended intervals and check the fuel, air and transmission filters at the same time. Consider changing to low-viscosity oil in winter, as it will flow more easily between moving parts when cold. In sub-zero driving temperatures, drop oil weight from 10-W30 to 5-W30 as thickened oil can make it hard to start the car.
- Lights & Wipers – Make sure all exterior and interior lights are working so you can see and be seen. Check the fluid level in the windshield washer reservoir and replace wiper blades that are torn, cracked or don’t properly clean your windshield.
