How should I understand the "3-year or 30,000 km maintenance cycle for the range extender after its first service"? What other maintenance precautions are there?
First of all, both "3 years for the whole vehicle" and "30,000 km for the range extender" refer to the maintenance cycle of the range extender, not the maintenance cycle of the whole vehicle. If either of these two conditions is met, the range extender needs to be maintained, whichever comes first.
All models in the Xiaomi Pengcheng series are equipped with the same range extender and follow this maintenance standard, with no differences between high and low trims.
In addition, routine maintenance items such as the vehicle's air conditioning filter, brake fluid, chassis inspection, and three-electric system testing should still be carried out at the store normally according to official maintenance specifications. After the vehicle is officially launched, maintenance information will be detailed in the user manual. At that time, you will also be able to view it in the infotainment system and the Xiaomi EV App.
