Automatic air conditioning system, Heated rear window/Door mirror heating
107
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Automatic control is no longer active.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:
fDo not cover the sun sensor on the instrument
panel or the temperature sensor C.fPress 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:
fPress AC OFF button D.
The compressor is switched off.
The light-emitting diode in the button lights up.
fIf 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.fPress 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.
fOnly select recirculating-air setting for short
periods.
fIf the windows fog up, switch recirculating-air
setting off immediately by pressing the
circulating-air button again and select the “Defrost windshield” function.

Automatic air conditioning system, Heated rear window/Door mirror heating 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.fPress button H.
The air flows to the footwell.
The selection appears on the display panel.
fPress button I.
The air flows from the central and side vents.
Vents must be open.
The selection appears on the display panel.
fPress button J.
The air flows to the windshield.
The selection appears on the display panel.
Note on operation
fOn vehicles with the Sport Chrono Package
Plus, individual air conditioning settings can be
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.
– 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
temperature has been set, switch off the air-
conditioning compressor and have the fault
repaired at an authorized Porsche dealer. Air distribution to footwell

Pointer to the left – engine cold
fAvoid high engine speeds and heavy engine
loading. Pointer in the middle – normal operating tem-
perature
The pointer may move up to the red area when en-
gine is heavily loaded and outside temperature is
high, but should return to “normal” when engine
load is reduced.
Warning light “A” If the coolant temperature is too high, the warn-
ing light comes on.
Additionally, a warning is displayed in the on-board
computer.
fPull off the road, turn off the engine and allow
to cool.
fCheck radiator and air passages in front end of
car for obstructions.
fCheck coolant level.
If necessary, add coolant and have fault reme-
died at an authorized Porsche dealer.
Please see the chapter “COOLANT LEVEL” on
Page 207.
Note
To prevent excessive temperatures, the cooling-
air passages must not be restricted by coverings
(e.g. films, “stone guards”). If the coolant level is too low, the warning light
flashes.
Additionally, a warning is displayed in the on-board
computer.
fSwitch engine off and allow to cool.
fAdd coolant after the engine has cooled to the
touch.
fHave the cause of the fault remedied at an au-
thorized Porsche dealer.
Please see the chapter “COOLANT LEVEL” on
Page 207.
Caution!
Risk of engine damage.
fIf the warning lights come on even though cool-
ant level is correct, do not continue driving.
fHave the fault remedied at the nearest authorized Porsche dealer.
Engine compartment blower fan In addition, this warning light flashes to indicate a
fault in the engine compartment blower fan.
fHave the cause of the fault remedied at an
authorized Porsche dealer.

Coolant LevelfPlease see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on Page 206.
The cooling system is filled at the factory with a
permanent coolant.
It provides year-round protection from corrosion
and freezing down to –31 °F/–35 °C
.
fOnly use antifreeze authorized by Porsche.
Checking coolant level The expansion tank with its filler orifice is in the en-
gine compartment.
fCheck the coolant level regularly through the
transparent expansion tank.
When the engine is cold and the car is level the
fluid level must lie between the “MIN” and “MAX”
markings. Topping off coolant
Warning!
Danger of serious personal injury or death
from scalding. Coolant is hazardous to your
health, and may be fatal if swallowed.
fDo not open the cap of the expansion tank
while the engine is hot.
fAllow the engine to cool down before opening
the cap and protect your hands, arms and face
from any possible escape of hot coolant.
fKeep coolant out of children’s reach.
fAlso, keep coolant away from your pets.
They can be attracted to it should there be a
spill, or to used coolant left in an open contain-er. Coolant can be deadly to pets if consumed.1. Switch engine off and let it cool.
Please see the chapter “COOLING SYSTEM” on
Page 120.
2. Cover the expansion tank cap with a thick rag.
Open cap slowly and carefully and allow over-
pressure to escape.
Then unscrew cap completely.
3. Only add a mixture of antifreeze and water in
equal parts, and do not exceed the “MAX”
mark.
Antifreeze in coolant:
50% gives protection down to –31 °F/–35 °C
60% gives protection down to –58 °F/–50 °C
4. Screw cap firmly on.
If in an emergency pure water has been added, the
mix ratio must be corrected at an authorized
Porsche dealer.
Marked loss of coolant indicates leakage in the
cooling system.
The cause should immediately be remedied at an
authorized Porsche dealer.
