Information on air-conditioning
compressorThe 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. 37.4°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.
Notes on operation
Depending on the outside temperature and humid-
ity, condensation can drip from the evaporator
and form a pool under the car.
This is normal and not a sign of leakage.
If uncooled air flows out when the lowest temper-
ature has been set (“LO”), switch off the air-condi-
tioning compressor and have the fault remedied at
an authorized Porsche dealer.
REST modeUsing engine residual heat
The residual heat of the engine can be used to
heat the interior up to 20 minutes after the ignition
has been switched off.
fPress REST button N.
The air-conditioning settings cannot be
changed in REST mode.
Ending the function
fPress REST button N.
Note on operation
If the battery positive voltage is too low, REST
mode is automatically ended.
