It is possible to set whether automatic start for the additional heater should be activated/deactivated.
Open the climate view in the centre display by tapping on the temperature button at the bottom centre of the centre display.
Press
Activate/deactivate automatic start of Heater.
Note
If the auxiliary heater's automatic starting is deactivated, this may impede comfort in the passenger compartment as the climate control system will then have no heat source during electrical operation.
