Automatically Controlled
Four-Zone Air ConditioningDepending on various factors (e.g. ambient tem-
perature, sunlight, air quality), the air-conditioning
system controls the preset interior temperature
fully automatically.
Temperature, air quantity and air distribution can
be set individually for the front left, front right, rear
left and rear right air-conditioned areas.If necessary, the automatic system can be manu-
ally influenced.
This individual adjustment is shown on the air-con-
ditioning display panel.
DisplayThe air-conditioning display panel shows the fol-
lowing:
– Air quantity
– Selected interior temperature
– Individual settings
– Time that is identical to that shown in the in-
strument panel.

Setting temperatureTo suit personal comfort, the interior temperature
for each of the four air-conditioned areas can be
adjusted between 61°F and 85°F (16°C and
29.5°C).
Recommendation: 72°F (22°C)
fPush temperature button up or down.
ButtonH:
Left air-conditioned area at the front or rear.
Button R:
Right air-conditioned area at the front or rear.
The selected temperature is shown on the
display above the button.
If “LO” or “HI” appears on the display, the system
is operating at maximum cooling or heating pow-
er.
If the preselected temperature is changed, the air
quantity blowing out can adjust automatically in au-
tomatic mode.
The desired temperature is reached more quickly
this way.

fOnly select recirculating-air mode for short
periods.
fIf windows mist up, end circulating-air mode by
pressing the circulating-air button again and selecting the function “Defrost windshield”.
fPress button D on the front control panel
twice.
Indicator light in button lights up.
The outside-air supply is interrupted and only
the inside air is circulated.
Note on operation

If the air-conditioning compressor is
switched off, the windows may mist up.
fDo not switch off the air-conditioning compres-sor in damp weather.
Switching air-conditioning compressor off
Whenever outside temperatures exceed 37.4°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 ECON button N on the front control pan-
el. The air-conditioning compressor is
switched off.

fIf the interior temperature is too high:
Press ECON button Nor
Press the AUTO button C.
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 inte-
rior 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.

Parking HeaterThe parking heater features two functions: parking
heating and parking ventilation.
The parking heater is ready for use regardless of
the ignition key position.
The parking heater is also used as an auxiliary
heater. Operation of the parking heater is clearly
audible when outside temperatures are low, even
if the parking heater has been manually switched
off.
Danger!
Risk of poisoning due to carbon monoxide
(CO). The parking heater consumes fuel and
emits exhaust fumes. Exposure to such
fumes can cause unconsciousness, serious
personal injury or death.
fSwitch off the parking heater before refuelling.
fDo not operate the parking heater in enclosed spaces (e.g. a garage).
The parking heater is operated using the following
buttons on the front air-conditioning control panel:
Switch parking heater on and off
Activate program
Start programming
Call memories
Set ON times
Activate heating function

Car Audio Operation/TipsFor radio operation see your radio manual
which is included with your on-board litera-
ture.FM receptionA vehicle is not an ideal place to listen to a radio.
Because the vehicle moves, reception conditions
are constantly changing.
Buildings, terrain, signal distance and noise from
other vehicles are all working against good recep-
tion.
Some conditions affecting FM may appear to be
problems when they are not.
The following characteristics are completely nor-
mal for a given reception area, and they do not in-
dicate any problem with the radio itself.
Note
Electronic accessories should only be installed by
your authorized Porsche dealer.
Equipment which has not been tested and ap-
proved by Porsche may impair radio reception.Fading and drifting
FM range is limited to about 25 miles (40 km), ex-
cept for some high power stations.
If a vehicle is moving away from the desired sta-
tion's transmitter, the signal will tend to fade and/
or drift. This condition is more prevalent with FM
than AM, and is often accompanied by distortion.
Fading and drifting can be minimized to a certain
degree by careful attention to fine tuning or selec-
tion of a stronger signal.
Static and fluttering
When the line-of-sight link between a transmitter
and vehicle is blocked by large buildings or moun-
tains, the radio sound may be accompanied with
static or fluttering because of the characteristic of
FM.
In a similar effect, a fluttering noise is sometimes
heard when driving along a tree-lined road.
This static and fluttering can be reduced by adjust-
ing the tone control for greater bass response un-
til the disturbance has passed.Multipath
Because of the reflecting characteristics of FM, di-
rect and reflected signals may reach the antenna
at the same time (multipath) and cancel each other
out.
As a vehicle moves through these electronic dead
spots, the listener may hear a momentary flutter
or loss of reception.
Station swapping
When two FM stations are close to each other, and
an electronic dead spot, such as static or multi-
path area, interrupts the original signal, some-
times the stronger second signal will be selected
automatically until the original one returns.
This swapping can also occur as you drive away
from the selected station and approach another
station of a stronger signal.
