Winter checklist
Winter is tough on your vehicle. Start by getting your battery tested: cold weather reduces its capacity by 30 to 50%, and a battery over 4 years old could fail at the worst possible moment. Check the condition and pressure of your winter tires — tread depth should be at least 3.5 mm for good grip on snow and ice. Top up with winter-grade washer fluid that resists freezing down to -20°C. Inspect all lights (headlights, taillights, fog lights) since they get much more use with shorter days. Make sure the heating and defroster are working properly. Finally, keep emergency gear in the trunk: an ice scraper, a blanket, and jumper cables.
Summer checklist
Summer is the season for long trips and hot weather. Get your air conditioning checked before you head out — a poorly maintained system can harbor bacteria and lose efficiency. Check your coolant level: engine overheating can happen quickly in hot weather, especially in traffic jams. Check tire pressure (when cold), since heat expands the air and alters pressure. Inspect your windshield wiper blades: streaks across the glass reduce visibility during summer thunderstorms. Have your brakes checked before your vacation departure — pads, discs and brake fluid level. One final tip: check your spare tire or puncture repair kit — it's something we never think about enough.
Spring checklist
Spring is the perfect time to erase the traces of winter. Wash the underbody and wheel wells thoroughly to remove road salt, which promotes corrosion. Check your shock absorbers — winter potholes have put them to the test. Replace the air and cabin filters: they've accumulated moisture and impurities over the winter. Inspect your summer tires before mounting them back on: tread depth, uneven wear, and pressure. This is also a good time to check the brakes (discs and pads) and get an oil change if it's due. Finally, inspect the accessory belt and hoses — cold weather can make them brittle.
