respective remote control when switching off the
ignition and locking the vehicle. The "Air flow OFF"
setting is stored for approx. 60 minutes and the
"Circulating air ON" setting is stored for approx.
20 minutes.
REST mode
Using engine residual heat
The residual heat of the engine can be used to
heat the interior for up to 20 minutes after the
ignition has been switched off.

Warning!
Risk of accident due to hampered vision.
The outside air that is flowing in is not dried
in Econ mode. The windows may mist up.
f Do not switch on ECON mode in damp
weather.
In ECON mode, the air-conditioning compressor is
switched off and this deactivates the cooling
function (e.g. to save fuel).
The air-conditioning compressor is always
switched off at temperatures below 3 °C.

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 vehicle.
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.
