Press the settings symbol
.

Go to Heater.
Enable the additional heater.
The auxiliary heater starts automatically when heat is required while driving.
Note
If you deactivate the auxiliary heater's automatic start, it may impact comfort in the passenger compartment. This is because the climate control system will then have a reduced source of heating during your drive.
