If a diesel engine car has a parking heater, the car will have both the additional heater and parking heater functions.

If the parking heater has been programmed and the driver comes to the car earlier than anticipated, the additional heater will not engage until the car is started. The additional heater then determines if the heater should be on or off, even if the driver attempts to disengages the heater using the control stalk.
