Check Your Tires

As winter approaches, ensuring your tires are in top condition is crucial for safe driving. Cold temperatures can cause tire pressure to drop, so check your tire pressure regularly and inflate them to the recommended levels. Additionally, consider switching to winter tires, which provide better traction on icy and snowy roads.

Inspect Tire Tread

Beyond pressure, the tread depth is vital for maintaining grip on slippery surfaces. Use a tread depth gauge or the penny test—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.

Battery Health

Winter weather can be harsh on your vehicle's battery. Cold temperatures reduce a battery's cranking power, making it more difficult to start your engine. Have your battery tested to ensure it's holding a charge properly. If it's more than three years old, consider replacing it to avoid unexpected breakdowns.

Clean Battery Terminals

Corrosion can build up on battery terminals, impeding electrical flow. Regularly clean the terminals with a mixture of baking soda and water to prevent starting problems. Make sure the connections are tight and secure after cleaning.

Fluids and Oil

Proper fluid levels are essential for vehicle performance, especially in winter. Check and top off antifreeze, brake fluid, and windshield washer fluid. For oil changes, consider using a winter-grade oil that remains fluid in low temperatures, ensuring your engine runs smoothly.

Windshield Washer Fluid

A clear windshield is critical for safe driving. Use a winter formula windshield washer fluid that won't freeze and keep an extra bottle in your vehicle. Ensure your wiper blades are in good condition or replace them if they leave streaks.

Heating and Defrosting Systems

Efficient heating and defrosting systems are vital for comfort and visibility during winter months. Test your heater to ensure it warms the cabin effectively. Additionally, make sure the defroster vents are working properly to prevent ice and fog buildup on windows.

Check HVAC System

A functioning HVAC system is not just for comfort but also for safety. It helps maintain visibility by keeping your windows clear of fog and ice. Schedule a checkup if the system isn't performing as expected to avoid issues during colder days.
