The technician will start the vehicle and turn on the air conditioning system, measuring the actual temperature at the vents at the lowest and highest settings with a thermometer; at the same time, they will connect a manifold pressure gauge to check if the refrigerant pressure in the high and low pressure lines is within the normal range, determining if there is a chronic refrigerant leak.

Many car owners do not have their first maintenance done at authorized dealerships, leading to gaps in early data. In such cases, we do not blindly trust the odometer; instead, we analyze the tire production dates and wear levels, as well as the depth of grooves on the brake disc edges, using the "gold standard" of physical wear to infer the intensity of early use.

We must inform you objectively: Most Chinese car manufacturers' connected services (cloud servers) are restricted by data security regulations and overseas network limitations. Once the vehicle leaves China, the factory-installed SIM card will become inactive. This means that official OTA upgrades and factory mobile app remote controls (like pre-cooling the car or unlocking doors) typically cannot be used overseas. The vehicle will operate as a standalone version, but this will not affect basic driving and physical button functions.
