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Automatic control is no longer active.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.

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.
f Press button I.
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.
The selection appears on the display panel.
Note on operation
f On 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 th e 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.

ambient brightness by the light sensor in the
tachometer.
In addition, when the car lights are switched on,
the instrument and switch symbol brightness can
be manually adjusted.
Warning!
Risk of loss of control or accident, resulting
in serious personal injury or death.
f Do not reach through the steering-wheel spokes while driving.

Tachometer The tachometer shows the engine speed in revolu-
tions per minute (rpm).
The beginning of the red marks at the right end of
the scale indicates the maximum permissible en-
gine rpm.
A speed limiter prevents the engine from being
overrevved during acceleration. Before reaching
this area, the next higher gear should be select-
ed.
Shift to the next lower gear when the engine rpm
drops below 1,500 rpm.
Caution!
To avoid severe engine damage.
f Always observe the engine rpm before down-
shifting to a lower gear, so you do not exceed the maximum engine rpm.
Flashes in synchronism with the turn signals.
Left arrow – left turn signals
Right arrow – right turn signals
f If the frequency of the display becomes notice-
ably faster, check the operation of the turn sig-
nals.
Lights when high beam or headlight flasher is
switched on.
The indicator light goes out when the high beams
are switched off.
The indicator light flashes in the event of cornering
light failure.
Gear Shift Indicator(in vehicles with manual transmission)The consumption-orientated gear shift indicator A
on the display panel of the on-board computer
assists a fuel-saving driving style. The gear shift
indicator lights up as a recommendation to shift
up to the next-higher gear depending on the
selected gear, engine rpm and accelerator pedal
position.
f When the gear shift indicator A lights up,
change to the next higher gear to decrease
fuel consumption.

perature
The pointer may move up to the red area when en-
gine is heavily loaded and outside temperature is

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.
f Pull off the road, turn off the engine and allow
to cool.
f Check radiator and air passages in front end of
car for obstructions.
f Check coolant level.
If necessary, add coolant and have fault reme-
died at an authorized Porsche dealer.
Please see the chapter “COOLANT LEVEL” on
Page 197.
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.
f Switch engine off and allow to cool.
f Add coolant after the engine has cooled to the
touch.
f Have the cause of the fault remedied at an au-
thorized Porsche dealer.
Please see the chapter “COOLANT LEVEL” on
Page 197.
Caution!
Risk of engine damage.
f If the warning lights come on even though cool-
ant level is correct, do not continue driving.
f Have the fault remedied at the nearest authorized Porsche dealer.
