Car maintenance is a key process to ensure vehicle performance and safety, mainly consisting of three categories: daily maintenance, periodic maintenance, and non-periodic maintenance. Periodic maintenance is categorized by mileage or time intervals: primary maintenance (7,500 to 15,000 kilometres or 6 months) emphasizes lubrication and tightening, including oil and filter changes, and inspections of coolant and brake fluid; secondary maintenance (15,000 kilometres or 12 months) is more comprehensive, involving air filter replacement and brake system inspections. Non-periodic maintenance includes break-in maintenance for new vehicles, seasonal adjustments (e.g., battery checks in winter and air conditioning system cleaning in summer), and maintenance for long-term parked vehicles. For routine items, engine oil and filters should be replaced every 5,000 to 10,000 kilometres, air filters inspected or replaced every 10,000 kilometres, brake fluid renewed every 2 years or 40,000 kilometres, and tyre pressure checked monthly with regular rotation. Owners should strictly adhere to the vehicle manual's recommendations and adjust maintenance intervals appropriately based on driving conditions (e.g., dusty environments or frequent short trips) to prolong vehicle lifespan and ensure road safety.
