Information on air-conditioning
compressor
The air-conditioning compressor:
– May switch off briefly to ensure sufficient
engine cooling if the engine is operating under
extreme load.
– Switches off automatically at temperatures
below approx. 37.4 °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,
however, 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 eva-
porator and form a pool under the car.
This is normal and not a sign of leakage.
f If uncooled air flows out when the lowest
temperature has been set ("LO"), switch off the
air-conditioning compressor and have the fault
remedied at an authorized Porsche dealer.
