Solution

1. Battery Maintenance

Sub-steps:
- Remove the battery terminals (negative first, then positive).
- Clean the terminals and connector surfaces with a wire brush.
- Test the battery charge using a multimeter (should be above 12.6 volts).
- If necessary, replace with a battery rated for cold weather (higher CCA - Cold Cranking Amps).

2. Engine Oil Change

Sub-steps:
- Drain the existing oil using an oil pan.
- Replace with winter-grade synthetic oil (5W-30 or as specified in the owner’s manual).
- Replace the oil filter while the oil is draining.
- Refill the engine with the new oil and check the level.

3. Windshield Washer Fluid Preparation

Sub-steps:
- Drain the existing washer fluid reservoir.
- Refill with a winter-specific washer fluid that has a lower freezing point.
- Run the washer system to ensure the new fluid is distributed through the lines.

4. Door Seal and Lock Care

Sub-steps:
- Inspect all door seals for cracks or wear; replace if necessary.
- Lubricate door locks and seals with silicone spray or lock lubricant.
- Ensure that all locks operate smoothly without resistance.

5. Coolant System Check

Sub-steps:
- Check the coolant level in the reservoir.
- Test the antifreeze mixture using a hydrometer; ensure it is at least a 50/50 ratio with water.
- Top off or replace the coolant if necessary.
