Technical Description: 

Interior Heating Performance: 

US Market: 

The average Outlet temperatures of the heater and DEF discharges shall be a minimum of 61°C when tested in the following conditions.

Air flow 425 kg/h in heater mode
Air flow 450 kg/h in DEF demist mode
Coolant flow 0.2 l/s (50% water, 50% glycol)
Ambient -20°C
Coolant In 85°C
Coolant dP <25 Pag

Defrosting and Defogging: 

Windshield and side window DEF:

HVAC FRT UNIT shall provide a DEF function which, if selected by the operator, defogs and defrosts the windshield and side window.

Windshield and side window defogging/refogging:

HVAC FRT UNIT shall provide a defogging/refogging function, if selected by the operator, defogs and refogs the windshield and side window.

Air Conditioning: 

The refrigerant system is used for cooling in both the HVAC and powertrain cooling systems. The air conditioning system blows cooled outside air into the passenger compartment. The air suctioned by the blower is filtered (particle and/or ionizer), mixed with warm air in the air distributor housing, and distributed via the air vents.

The different settings can be directly changed by touching the fields with blue borders. The particular field then lights up in color, and manual temperature, fan, seat heating (seat ventilation only with Plus equipment variant) settings can be made directly.

Swipe upwards in the climate bar to open the climate control panel:

The setting can be changed by touching the icons in the climate control panel. Active buttons are highlighted in color, and inactive icons are grayed out. The temperature, ventilation, seat heating (seat ventilation only in the Plus equipment variant) and, in addition, the air outlets can also be changed here.

Please see the operating instructions for an exact description of how to operate the C-App and the MHU.
