A tu po angielsku:
1. Make sure all windows & doors are closed.
2. Turn ignition switch to on (don't start car). Wait 10 seconds.
3. Flash highbeams 5 times using the "flash to pass" stalk on the side of the steering wheel (on/off, on/off, on/off, on/off, on/off).
4. Press brake pedal 3 times in 10 seconds.
5. The battery light on instrument cluster will flash indicating the BMS has been reset.
