Parking heater (optional extra)
The start time of the heater is programmed as follows:
- the desired parking function is selected by turning the ring on the control stalk
- the desired time is selected by turning the ring on the control stalk
- press the RESET button.
Direct start can also be used to start the heater.
The climate control module (CCM) is activated when the engine coolant temperature (ECT) is greater than +20 °C. The blower fan starts and distributes the air in the passenger compartment.
Certain conditions must be met before the heater can start. These are:
- Quantity of fuel greater than 4 liters
- No diagnostic trouble codes (DTCs) that will prevent starting are stored in the central electronic module (CEM)
- The airbags have not deployed.
When the conditions are met, the heater glow plug is activated for 1 minute. If the voltage has dropped below 11.5 V, the climate control module (CCM) is switched off. The heater and the climate control module (CCM) are stopped if the voltage falls below 11.3 V. A message indicating low battery voltage is displayed in the driver information module (DIM). These voltage values apply even if the heater is operating normally.
To minimize the risk of the fuel pump for the heater failing due to lack of use, the central electronic module (CEM) sends a signal every week to the combustion preheater module (CPM) to activate the pump for approximately 1 second. This takes place when the ignition is switched off.
Remote start of parking heater (Applies from and incl. structure week 201020)
With remote start of parking heater it is possible to set timers for the parking heater as well as direct start of the parking heater via a computer with internet connection or via mobile telephone. Only applies to vehicles with Phone module (PHM).
