Even in Mississippi, where winters are relatively mild compared to northern states, cold weather can create challenges for your vehicle. Freezing temperatures, occasional ice, and winter storms require some extra preparation. Here's how to winterize your car and stay safe on the road.

1. Check Your Battery

Cold weather reduces battery capacity significantly. A battery that struggles in summer may fail completely when temperatures drop. We recommend having your battery tested before winter arrives.

Warning signs of a failing battery:

• Engine cranks slowly when starting
• Dashboard lights dim when idling
• Vehicle is more than 4 years old
• Previous jump-start required

2. Inspect Coolant and Antifreeze

Proper coolant mixture prevents freezing and protects your engine from corrosion. We recommend a 50/50 mix of antifreeze and distilled water for most vehicles.

Check for:

• Proper coolant level
• No discoloration or contamination
• No leaks visible under the vehicle

3. Evaluate Your Tires

Even in Mississippi, we can see temperatures below freezing and occasional ice on bridges and overpasses.

• Tread depth: At least 2/32" for safe driving, 4/32"+ for better traction
• Tire pressure: Check monthly as tires lose 1 PSI per 10°F temperature drop
• Sidewall damage: Look for cracks, bulges, or embedded objects

4. Replace Wipers and Fluid

Winter road spray and slush require effective wipers and freeze-resistant washer fluid.

• Install winter blades if you experience heavy ice buildup
• Use freeze-resistant washer fluid (not plain water)
• Carry an ice scraper in your vehicle

5. Check Oil Viscosity

If you use conventional oil, consider switching to a lower viscosity oil in winter. Thinner oil flows more easily when cold, reducing engine wear on startup.

Check your owner's manual for the recommended viscosity grade for cold weather operation.

6. Inspect Brakes Thoroughly

Wet, slick roads require reliable brakes. Have your brake pads, rotors, and calipers inspected before winter weather arrives.

Watch for:

• Longer stopping distances
• Grinding or squealing sounds
• Soft or spongy brake pedal
• Vehicle pulling to one side under braking

7. Keep Your Gas Tank Full

A full tank prevents fuel lines from freezing and adds weight for better traction. Keep your tank at least half full during winter months.

8. Prepare an Emergency Kit

Even on short trips, winter conditions can strand you. Keep these items in your vehicle:

• Blankets and warm clothing
• Flashlight with extra batteries
• First aid supplies
• Non-perishable snacks and water
• Jumper cables
• Ice scraper
• Road flares or warning triangles

9. Know Your Heating System

Test your heater and defroster before you need them. If warm air doesn't come on quickly or windows fog excessively, have the system checked.
