Winter Car Maintenance Checklist for 2024
British winters can be unpredictable, and preparing your car for the cold months is essential for safety and reliability. Whether you drive a BMW, Mercedes-Benz, Audi, or any other vehicle, this winter maintenance checklist will help keep you safe on the road.
Tyres: Your First Line of Defence
Check your tyre tread depth — the legal minimum is 1.6mm, but for winter safety, we recommend at least 3mm. Consider switching to winter tyres if you regularly drive in cold conditions, as they provide significantly better grip below 7 degrees Celsius. Check tyre pressures weekly during winter, as cold temperatures cause pressure to drop. Don't forget to check your spare tyre or ensure your tyre repair kit is complete and within its expiry date.
Battery Health
Cold weather is the biggest killer of car batteries. A battery that's been fine all summer can fail at the first frost. If your battery is more than three years old, have it professionally tested. Keep terminals clean and free of corrosion. Modern premium vehicles with numerous electrical systems place heavy demands on batteries, so it's worth investing in a quality replacement if yours is showing signs of weakness.
Lights and Visibility
With shorter days and often poor weather conditions, visibility is critical. Check all lights are working correctly — headlights, tail lights, brake lights, fog lights, and indicators. Clean your headlight lenses, as they can become cloudy over time, reducing their effectiveness. Ensure your windscreen wipers are in good condition and top up your screen wash with a winter-grade solution that won't freeze.
Fluids and Antifreeze
Check your coolant level and ensure it contains the correct antifreeze concentration — your handbook will specify the right mix. Check engine oil level and condition; if it's due for a service, get it done before winter sets in. Power steering fluid, brake fluid, and transmission fluid should all be at the correct levels.
Emergency Kit
Prepare a winter emergency kit for your boot: a blanket, torch with spare batteries, ice scraper and de-icer, jump leads, high-visibility vest, mobile phone charger, and some snacks and water. If you regularly drive in rural areas, consider adding a small shovel and some grit or cat litter for traction on icy surfaces.
Heating and Climate Control
Test your heating system before you really need it. Run the air conditioning for a few minutes to keep the system lubricated and to help demist windows effectively. If your car has heated seats, heated steering wheel, or heated windscreen, check they're all functioning correctly. These features aren't just luxuries in winter — they're genuine safety aids.
