How to do it

  1. Have the battery load tested at a parts store or garage before the first cold snap.
  2. Check tire tread and pressure, since pressure drops as the air cools, or fit winter tires if you drive in snow.
  3. Fill the washer tank with a winter-rated fluid that will not freeze.
  4. Replace wiper blades that streak or chatter.
  5. Check the coolant level in the see-through reservoir with the engine cold.
  6. Pack an ice scraper, a snow brush, a blanket, gloves, a small shovel and a bag of sand or cat litter.
  7. Keep the fuel tank at least half full in winter.
  8. On snow or ice, slow down, brake and steer gently, and leave several times your normal following distance; take a winter driving course if you are new to it.

Stop and call a professional if

  • The battery tests weak, or the car cranks slowly on cold mornings: have the battery and charging system checked by a mechanic before it strands you.
  • Coolant is low again soon after topping up, or you see a leak: have the cooling system checked by a mechanic.

Common mistakes

  • Topping up with summer washer fluid that freezes in the lines.
  • Driving off with only a peephole scraped in the windshield.
  • Assuming all-season tires grip like winter tires on ice.

Quick self-check

Three questions. Your last score is kept in this browser.

1. What happens to tire pressure as it gets colder?
2. Which washer fluid belongs in the tank in winter?
3. How should you drive on snow or ice?
