It is possible to set whether automatic start for the auxiliary heater should be activated or deactivated.
Tap Settings in the Top view in the center display.
Tap Climate.
Select Additional Heater to activate/deactivate automatic start for the auxiliary heater.
Note
If automatic start of the auxiliary heater is deactivated, this may impair comfort in the passenger compartment since the climate system then does not have a heat source during electrical operation.
