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. 3 °C and cannot be switched
on, even manually.
– Operates most effectively with the windows
closed.
If the vehicle 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 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.
Consult a qualified specialist workshop. We
recommend that you use a Porsche partner for
this work since these are staffed with trained
personnel and have the necessary parts and
tools.
