Auxiliary Heater And Parking Heater
WARNING: This page is about a different car, the 2010 Volvo V70, 2009 Volvo V70, and 2008 Volvo V70. However, it is still accessible from the selected car via links, so may be relevant.
If the driver has programmed the parking heater, but arrives early, the auxiliary heater takes over when the vehicle is started. The auxiliary heater then determines whether the heater should be active if the driver has not manually deactivated the function using the control stalk of the steering wheel module (SWM) (3/130).
