Start with the owner's manual for your exact model and year—it lists the official service intervals and the required fluid specifications. If the manual is only in Chinese, ask the exporter for the English version, or check the manufacturer's website and owner community forums for your region. After the car arrives, do a baseline service even if the seller says it was just serviced: engine oil and filter, air filter, cabin filter, brake fluid check, coolant, and a 12V battery test. From then on, follow the "severe" or "extreme conditions" schedule rather than the normal one—dusty roads, short trips, and hot or very cold climates all count as severe duty, and intervals are usually shorter. Keep every invoice and record. A documented maintenance history makes warranty claims easier and protects resale value.

Most new car manufacturers' e-SIMs are directly soldered onto the T-Box motherboard (surface-mounted) and cannot be removed and replaced like a phone. Unauthorized desoldering of the motherboard may cause complete communication failure in the vehicle, and we strictly prohibit this operation.

It does not affect basic driving and regular speed cruise, but it will trigger a fault alert for advanced driver assistance on the dashboard. The LiDAR assembly is extremely expensive, so we focus on checking the integrity of the glass cover with a strong flashlight during inspections.
