The following hints will optimise the performance of your roof air conditioner:
Improve the heat insulation of your vehicle by sealing gaps and hanging reflective
blinds or curtains on your windows.
If the vehicle has been subjected to direct sunlight for a long time: Operate the roof air conditioner in the “Ventilation” mode with the windows open for a
while before switching on the “Cooling” air conditioning mode.
Avoid opening doors and windows as far as possible in the “Cooling” mode.
Align the air nozzles sensibly.
