Automatic air conditioning system, Heated rear window/Door mirror heating
Air ConditioningAir quantity, air distribution, and temperature can
be set on the control panel.The display panel shows the following– Temperature
– Air-conditioning compressor on/off
–Blower speed
–AC max
– Air distribution
Setting temperaturefPress button F upwards or downwards
respectively.
The selected temperature is shown on the display
by a bar display.
If a bar cannot be seen , the temperature is set
to maximum cold .
If all bars can be seen, the temperature is set to
maximum warm.
Note
f For maximum cooling, activate AC max
button G.

B - Heated rear window
C - Te m p e r a t u r e s e n s o r
D - AC OFF button (air-conditioning compressor off/on)
E - Recirculating-air button
F - Temperature button
G - AC max
H - Air distribution to footwell
I - Air distribution to central and side vents
J - Air distribution to windshield
K - Blower speed buttonf Press button K upwards or downwards
respectively.
The preset blower speed is increased or de-
creased.
The blower speed is shown on the display by a bar
display.
The compressor is switched off at low blower
speeds.

Automatic air conditioning system, Heated rear window/Door mirror heating
Information on air-conditioning
compressor– May switch off briefly to ensure sufficient engine cooling if the engine is operating under
extreme load.
– The air-conditioning compressor switches off automatically at temperatures below approx.
37 °F/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 hu- midity, condensation can drip from the evapo-
rator and form a pool under the car.
This is normal and not a sign of leakage.
– If uncooled air flows out when the lowest temperature has been set, switch off the air
conditioning compressor and have the fault
remedied.
Please contact your auth orized Porsche dealer
for further information.

114
Automatic air conditioning system, Heated rear window/Door mirror heating
Setting temperaturefPress button F upwards or downwards
respectively.
To suit personal comfort, the interior temperature
can be adjusted between 61 °F and 85 °F/16 °C
and 29.5 °C.
Recommendation: 72 °F/22 °C.
If “LO” or “HI” appears on the display, the system
is operating at maximum cooling or heating pow-
er.
Automatic control is no longer active.
Note
If the preselected temperature is changed, the
blower speed can increase automatically in auto-
matic mode.
The desired temperature is reached more quickly
this way.
Sensors
To avoid affecting the performance of the air-con-
ditioning system:
f Do not cover the sun sensor on the instrument
panel or the temperature sensor C. f
Press button A (switch on or off).
The windshield is defogged or defrosted as
quickly as possible.
Air flows to the windshield only.
The light-emitting diode in the button lights up.
AC OFF – switching compressor for air-
conditioning system on and offThe air-conditioning compressor switches off
automatically at temperatures below approx.
37 °F/3 °C and cannot be switched on, even
manually.
Whenever outside temperatures exceed approx.
37 °F/3 °C, the air-conditioning compressor is
always switched on in automatic mode.
The compressor can be switched off to save fuel,
but control comfort is then limited:
f Press AC OFF button D.
The compressor is switched off.
The light-emitting diode in the button lights up.
f If the interior temperature is too high, switch
compressor back on or press AUTO button.
To dry incoming air in damp weather, do not
switch off the air-conditioning compressor.
This prevents fogging of windows. f
Press button K upwards or downwards respec-
tively.
The preset blower speed is increased or
decreased.
The speed stages are indicated by a bar display.
If the button is pressed downwards at the lowest
blower stage, the blower and automatic control
are switched off. “OFF” will appear on the display
field.
Pressing the button upwards or pressing the
AUTO button switches the blower and automatic
control back on again.
Warning!
Risk of accident due to impaired vision,
resulting in serious personal injury or death.
In recirculating-air setting, the windows may
fog up.
f Only select recirculatin g-air setting for short
periods.
f If the windows fog up, switch recirculating-air
setting off immediately by pressing the
circulating-air button again and select the “Defrost windshield” function.

Switching recirculating-air setting on or off
fPress button E.
The outside-air supply is interrupted and only
the inside air is circulated.
The light-emitting diode in the button lights up.
Over approx. 37 °F/3 °C
If the air-conditioning compressor was off, it
switches on automatically. The duration of recircu-
lating-air setting is not limited.
Below approx. 37 °F/3 °C
The air-conditioning compressor is switched off.
Recirculating-air setting is automatically ended
after approx. 3 minutes.Air distributionThe individual air distributions can be combined as
desired.
Recommended setting in Summer:
Air distribution to central and side vents.
Recommended setting in Winter:
Air distribution to footwell and windshield. f
Press button H.
The air flows to the footwell.
The selection appears on the display panel.

The air flows from the central and side vents.
Vents must be open.
The selection appears on the display panel.
f Press button J.
The air flows to the windshield.

stored on your vehicle key.
Please observe the chapter “Individual
Memory” in the separate PCM operating
instructions.
General instructions for air-conditioning
compressor– Can switch off briefly if engine is under an ex-
treme load to ensure sufficient engine cooling.
