How the solar sensor affects the IHKA regulation on the driver's side and on the front-passenger side is not
programmed separately.
MAX cooling (IHKA only)
The MAX button makes it possible for the user to select maximum cooling with just one press of a button at the
IHKA controls.
When the MAX button is pressed, all functions, including the defrost function, are deactivated. The air-
conditioning function is activated (if it was not already activated) and defined settings are selected
(e.g. temperature control is deactivated, ventilation flaps are fully opened).
Residual heat (IHKA only)
The residual-heat function allows the waste heat from the engine to be used to heat up the vehicle interior when
the engine is not running (e.g. during a stop at a level crossing). The residual-heat function is only possible for a
certain run-down period (15 minutes from terminal 15 OFF). The auxiliary water pump is activated to circulate
the water.

•
Terminal 15 OFF

•
Run-down period active (up to 15 minutes after terminal 15 OFF)
