Specific operation steps are as follows: 1. Press the brake pedal of the BYD S7, turn on the ignition switch, and use the buttons on the steering wheel to enter and adjust the menu. Press the one-touch start button of the BYD S7 to start the engine. 2. All dashboard lights of the BYD S7 illuminate, indicating that the entire vehicle's electronic system is powered on. 3. Enter the maintenance menu option in the combination instrument panel and set the maintenance time (use the up and down buttons to increase or decrease the maintenance time by 15 days). 4. Touch the (Maintenance Option) on the central multimedia display screen to set the maintenance mileage (use the up and down buttons to increase or decrease the maintenance mileage by 500km). 5. Adjust the popped-up maintenance date and mileage, exit the maintenance menu, and complete the setup.
I've driven the BYD S7 many times myself, and the steps to reset the maintenance light are quite simple: First, turn the ignition switch to the OFF position, ensuring the car is completely shut down. Then, press and hold the TRIP button on the dashboard—that small button displaying the mileage—without releasing it. Next, turn the key to the ON position but do not start the engine. At this point, you'll see the maintenance indicator light begin to flash or change. Hold for about 10 to 15 seconds until the light turns off or stabilizes. Release the button, turn off the key, and then restart the car to check if the light has disappeared. I usually also confirm the vehicle is in P (Park) to prevent accidents, as the button position may vary slightly in different model years of the S7. If you have the manual, it's good to check. The maintenance light reminds you to change the oil or filter. Resetting it yourself saves a trip to the shop, but make sure to follow the scheduled maintenance. Otherwise, engine carbon buildup can affect performance, and in the long run, regular maintenance can save you a lot on repair costs.
When resetting the maintenance light, I first turn off the ignition to ensure the car is stationary and vibration-free. Hold down the TRIP button, turn the key to the ON position, observe the indicator light flashing, wait for about ten seconds before releasing, then turn off the key to verify once more. If unsuccessful, it might be due to poor button contact or a software bug—don't force it; it's best to consult the manual or a professional. As long as the battery isn't disconnected during the operation, it's simple and safe. If the maintenance light isn't reset, it will keep beeping annoyingly, but it's significant as it helps track oil life and prevents missing maintenance that could harm the engine. From my experience, not resetting it might lead to slower acceleration or increased fuel consumption. So learning this small trick makes daily driving more worry-free.
