Tap the symbol in the center of the climate bar to open Climate view in the center display.
Tap Use heat from drive to start climate comfort.
The climate comfort retaining function will be activated/deactivated and the button light will go on/off.
Note
Maintained climate comfort is not possible when there is not sufficient residual engine heat to maintain the climate settings in the passenger compartment, or if the outside temperature is above approximately 20 °C (68 °F).
Note
Climate comfort maintenance will be deactivated if the vehicle is locked from the outside in order to avoid using residual engine heat unnecessarily. This function is intended to be used to maintain climate comfort when the driver or a passenger remains in the vehicle after the engine is turned off.
The climate comfort retaining function is limited in duration in cold weather depending on the amount of residual warmth available.
