Very simple, start the Bluetooth, and the "Do Not Disturb" mode when connected to the car, to drive calmly with the hands-free of the car.

To deactivate it you have multiple options:

- Move away from the car and the Bluetooth of the car is disconnected
- Reopen the app
- Manually disable Bluetooth

For its optimal operation, the following configurations must be carried out (in this way we prevent the operating system from closing it while we are inside the car and allowing it to turn itself off when leaving the car):

- Disable energy saving mode for the app
- Put the lock in the task manager (doing it once is enough)
