## Winter Readiness Checklist

Winter driving demands vehicle prep and smart habits. Castle CDJR of Naperville can help you get ready for cold, snow, and ice.

### Critical Checks

**Battery:** Cold reduces battery power by up to 50%. Have yours tested; replace if it's 3+ years old.

**Tires:** Winter tires grip better than all-seasons below 45F. Check pressure monthly (cold air contracts, lowering PSI).

**Fluids:** Use winter-grade oil; top off coolant and windshield washer fluid (winter formula).

**Brakes:** Clear, responsive brakes are non-negotiable. Have pads and lines inspected.

**Lights & wipers:** Ensure all lights work; replace worn wiper blades.

### Supplies to Keep

Jump cables, blanket, flashlight, first-aid kit, sand/kitty litter, and jumper cables belong in every winter vehicle.
