After the vehicle arrives at the 4S store, inspect the paint surface, tires, and nameplate. The specific details are as follows: Inspect the paint surface: The uniformity and smoothness of the seams are the key points to check. It is best to compare with two vehicles of the same model. The gaps between the doors, bumper, and engine hood should be consistent. If the gaps are too large or the width differs from other vehicles, choose carefully. Inspect the tires: The sidewalls of new car tires should have no damage, and the front tire sidewalls and tread should show no puncture marks. It is best if the tire hairs on both front and rear tires are intact, at least the rear tire hairs should be visible. If there are no traces of tire hairs on the front and rear wheels but the odometer shows only a few kilometers, it is abnormal. Inspect the nameplate: Each vehicle's nameplate corresponds to the unique engine number and chassis number of the vehicle. Verify these numbers with the certification code to ensure consistency. Check the manufacturing date on the nameplate; the gap between the delivery time and the manufacturing time should not exceed three months.

When I take my car to the 4S dealership, I usually have them go through all the basic items. First, check if the engine oil is dirty and needs changing, and top up the coolant if the level is low. Tire pressure and tread wear should be inspected to ensure stability on the road—no underinflation or cracks. The lighting system can’t be overlooked either; check if the headlights and turn signals are working to avoid hazards when driving at night. Pay special attention to the braking system—pad thickness and hydraulic fluid levels—because failure could be disastrous. The air conditioning filter should be cleaned to maintain fresh air. Also, run an ECU scan to uncover hidden trouble codes and prevent minor issues from becoming major problems. Regular maintenance like this makes the car more reliable, especially for family vehicles—it’s all about peace of mind. Extending the car’s lifespan and avoiding constant repairs makes the cost worthwhile.

I pay close attention to technical details and always remind the dealership staff to perform professional diagnostics. Beyond basic items like engine oil and coolant, an ECU scan of the engine control unit is essential to check for sensor or wiring anomalies. Wheel dynamic balancing must be precisely adjusted to prevent alignment issues affecting handling. The braking system requires thorough inspection of discs and fluid levels to ensure quick response. Air conditioning efficiency should be tested, especially before summer to confirm cooling performance. Battery health checks should include voltage monitoring to avoid unexpected stalls. Cleaning the air filter improves combustion efficiency. Relying on professional tools simplifies maintenance and reduces sudden breakdowns. With numerous electronic components in modern vehicles, comprehensive inspections ensure reliability and boost driving confidence.

Safety is the top priority, so as soon as I arrived at the 4S dealership, I had them closely inspect the brakes and lights. They checked the thickness of the brake pads and the wear on the brake discs to ensure stable emergency stops. The brightness of the lights was adjusted correctly to avoid accidents during night driving. The suspension system was thoroughly examined, checking the shock absorbers and stability to prevent loss of control when hitting potholes. The airbag system was scanned with tools to confirm it was fully functional. The wipers and battery voltage were also verified. These priority items ensure safe driving, especially on highways or in harsh weather conditions—life should never be taken lightly. Addressing minor issues promptly helps prevent accidents on the road.
