Benefits & Arguments
Comfortably warm interior
Aids defrosting of the windows
Protects the engine by preheating the coolant prior to starting
This system is particularly recommended for vehicles with BlueTEC engines which will be
used in very cold climate regions. Since these engines are extremely efficient, their
thermal energy may not always be sufficient, at extremely low ambient temperatures, to
guarantee a comfortable level of warmth in the cab. The stationary heating function
allows the interior to be warmed even before the engine is started, so the driver can step
into a pleasantly warm vehicle right from the start.
Remarks
Note:
As of 01/2010 US emission regulations require the heater booster to be only optional with
outside temperatures below < 4∘C (39.2∘F).
