Check Your Tires

As temperatures drop, tire pressure can decrease, leading to reduced traction on icy or snowy roads. Make sure to check your tire pressure regularly and inflate them according to the manufacturer's recommendations. Additionally, consider switching to winter tires, which are designed to provide better grip in cold conditions.

Inspect Tire Tread

The tread on your tires is crucial for maintaining control on slippery surfaces. Use the penny test to check tread depth: insert a penny into the tread with Lincoln's head down. If you can see the top of his head, it's time to replace your tires. Ensuring adequate tread depth will help you stay safe during winter driving.

Test the Battery

Cold weather can significantly reduce a car battery's performance. Before winter sets in, have your battery tested to ensure it is holding a charge and functioning properly. If your battery is more than three years old, consider replacing it to avoid getting stranded in the cold.

Clean and Protect

Corrosion can form around battery terminals, so clean them with a mixture of baking soda and water. After cleaning, apply a thin layer of petroleum jelly to the terminals to prevent further corrosion. This small step can help extend your battery's life.

Check Fluids

Fluids are essential for your car's operation, and several require special attention in winter. Check your antifreeze levels and ensure the mixture is appropriate for colder temperatures. Also, use winter-grade oil that flows better in cold weather.

Windshield Wiper Fluid

Switch to a windshield wiper fluid with antifreeze properties to prevent it from freezing. Additionally, inspect your wiper blades and replace them if they are worn or damaged to maintain visibility during snowstorms.

Prepare an Emergency Kit

Having an emergency kit in your car can be a lifesaver during winter. Include items such as a flashlight, blankets, non-perishable snacks, a first-aid kit, and a snow shovel. These items will be invaluable if you become stranded or need to provide assistance to others on the road.

Additional Safety Items

  • Jumper cables
  • Ice scraper and snow brush
  • Portable phone charger

Keeping these items in your car ensures you're prepared for any unexpected winter challenges.

Inspect Your Heating System

Your car's heating system is crucial for comfort and safety during winter. Make sure it's working properly before the cold hits. If you notice any issues, such as strange smells or reduced airflow, have it checked by a professional mechanic.

Defrost Functionality

The defrost system is essential for keeping your windshield clear. Test it to ensure it’s working effectively, as a clear view is vital for safe winter driving. If it's not functioning well, it might be time for maintenance or repairs.
