General instructions for air-conditioning compressor
– Can switch off briefly if engine is under an extreme load to ensure sufficient engine cooling.
– Switches off automatically at temperatures below approx. 37 °F/3 °C and cannot be switched on, even manually.
– Operates most effectively with windows closed.
If the car has been in the sun for a long time, it is a good idea to ventilate the interior briefly with the windows open.
– Depending on the outside temperature and humidity, condensation can drip from the evaporator and form a pool under
the vehicle. This is normal and not a sign of leakage.
– If uncooled air flows out when the lowest temperature has been set, switch off the airconditioning compressor and have
the fault repaired at an authorized Porsche dealer.
