Cold weather puts extra strain on car batteries because chemical reactions slow down in low temperatures, reducing battery power by up to 50%.

**Battery Care Essentials**
Keep your battery terminals clean and corrosion-free. Check that battery cables are secure and undamaged. If your car struggles to start on cold mornings, the battery may need testing or replacement.

**Cold-Weather Tips**
- Park in a garage or sheltered spot if possible.
- Reduce battery drain by turning off lights and accessories before starting.
- Use block heaters if available in your area.
- Keep your Hyundai well-maintained-a tuned engine starts more easily.
