The best time to service your vehicle is before winter. If servicing is not possible, you can carry out your own checks.
This should include:
Regularly checking the antifreeze concentration in the cooling system and topping it up to the appropriate winter level.
Checking the operation of wipers and the condition of the windshield, and refilling windshield washer fluid.
Checking all lights and immediately replacing any faulty bulbs.
Checking the battery and replacing it at the first sign of a problem.
Checking the brakes for proper function.
Inspecting tires for damage such as cracks, cuts, or bulges on the sidewalls. Any damage should be addressed immediately, as it can lead to slow air leaks or tire blowouts at higher speeds. The minimum tread depth should be 3 mm, and any tire with less than 2 mm tread should be replaced immediately. Never drive with underinflated tires – the idea that softer tires provide better grip is a myth.
