Solution

1. Battery Maintenance

Check Charge: Test battery voltage with a multimeter; replace if below 12.4 volts.
Clean Terminals: Disconnect the battery, clean terminals with a wire brush, and apply terminal protector.

2. Tire Preparation

Install Winter Tires: Remove all-season tires and install winter tires; check for proper inflation (typically 2-3 PSI lower than summer settings).
Tread Depth: Ensure tread depth is at least 6/32 inches for winter tires.

3. Fluid Checks

Engine Oil: Switch to a winter-grade oil if not already done; consult owner's manual for specifications.
Antifreeze: Check coolant mixture; it should be 50/50 antifreeze and water for optimal freezing protection.
Windshield Washer Fluid: Use a winter formula to prevent freezing.

4. Heating and Defrosting System

System Check: Test the heating and defrosting systems to ensure they are functioning properly.
Replace Filters: Change the cabin air filter for better airflow and heating efficiency.

5. Wiper and Lighting Maintenance

Wiper Blades: Replace wiper blades with winter-rated ones for improved visibility.
Check Lights: Ensure all headlights, taillights, and signal lights are functional and replace any burned-out bulbs.
