Good car maintenance is all about spotting the problem before it can cause real harm. One thing you need to check is your car's accessory belt drive system and the most important part of it is the belts. Be aware of any noise coming from the engine, particularly in the areas where these belts are installed. Then check if the belts are misaligned or already worn out, especially if there are cracks. If yes, then it’s time to have them replaced by an expert mechanic. To better understand the accessory belt drive system, check out these slides from Gates Australia.
