HVAC Menu

  1. turn the key in the second position
  2. turn the air conditioner on
  3. press the down-arrow button, the blue button (cold air) and the “ECON” button in the same time
    • To navigate through hidden or secret menu use only the blue and red buttons.
  4. press the “ECON” button to exit the hidden or secret menu
  5. turn the key off

Every code means something. For example CODE 01 = INTERIOR TEMPERATURE = 26° C
