[DiLucille]

Items included in the second car maintenance are: replacing engine oil, air conditioning filter, oil filter, and air filter. The engine's working condition will also be checked, such as whether the pipeline connections are normal, if there are any leakage points, if the engine's working sound is normal, and if there are any abnormal noises. The vehicle will also be lifted to check for any scratches or corrosion on the chassis components, as well as to inspect the braking system, suspension system, and the inner side of the tires to ensure everything is normal, thereby guaranteeing future usage safety. If the inspection and maintenance during the second maintenance are done thoroughly, it can improve the overall condition of the car and ensure driving safety. After the second maintenance, the car's performance and overall condition can enter a stable period, and usually, only the maintenance of wear-prone parts needs attention.
