Parking Heater

NOTE: OFF cannot be selected as long as the parking heater signal is active. This means that the selection can only be cancelled by either cancelling it in the DCC or the timer or by switching on the ignition.

A parking heater can be switched on using a timer or using the DCC trip computer and a signal is then sent to the ACC control module for the parking heater. Provided that the ignition is off, this results in the following selections:
- Air-mixing damper - normal automatic control
- Air-mixing damper - "defrost" and "hear" (damper angle 135° - 112.5°).
- Air recirculation flap - "Recirculation" when outside temperature is below -10 °C (14 °F) or "Fresh air" when outside temperature is above -8 °C (17.5 °F).
- Ventilation fan - motor current about 5.5 A.
- Electrically heated rear window and electrically heated door mirrors - OFF
- Rear door fans - OFF
- Air conditioning - ON (signal to A/C relay)
- Temperature display - last temperature selected (LO = +16 °C or 61 °F).
- LEDs - function normal
- Manual selection - all selections except OFF are possible.
