[Alaina]

Sedans should be maintained approximately every 5,000 kilometers or every 6 months. Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the vehicle, also known as car servicing. The purpose of car maintenance is to keep the vehicle clean, ensure normal technical conditions, eliminate potential hazards, prevent failures, slow down the deterioration process, and extend the service life. Maintenance items include: 1. Replacement of engine oil and oil filter, mainly for the maintenance of the lubrication system, which effectively lubricates various components of the car engine to prevent excessive wear; 2. Replenishment of brake fluid and transmission oil; 3. Spark plugs are consumables and should be checked during each maintenance; 4. Replacement of the air filter to filter the air before it enters the cylinder, removing impurities, dust, sand, and other foreign particles.
