General instructions for air-conditioning
compressor
– Can switch off briefly if engine is under an ex-
treme load to ensure sufficient engine cooling.
– Switches off automatically at temperatures be-
low 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 hu-
midity, condensation can drip from the evapo-
rator and form a pool under the vehicle.
This is normal and not a sign of leakage.
– If uncooled air flows out when the lowest tem-
perature has been set, switch off the air-condi-
tioning compressor and have the fault repaired
at an authorized Porsche dealer.
