Setting temperaturefPress button H upwards or downwards
respectively.
To suit personal comfort, the interior temperature
can be adjusted between 61°F and 85°F/16 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Automatic control is no longer active.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 D.fPress button B (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.
ECO – 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 ECO button E.
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.

Maintenance, Car Care
How Emission Control Works When an automobile engine is running, it uses en-
ergy generated through the combustion of a mix-
ture of air and fuel. Depending on whether a car is
driven fast or slowly or whether the engine is cold
or hot, some of the fuel (hydrocarbons) may not
be burned completely, but may be discharged into
the engine crankcase or exhaust system. Additon-
al hydrocarbons may enter the atmosphere
through evaporation of fuel from the fuel tank.
These hydrocarbons (HC), when released into the
air, contribute to undesirable pollution.
In addition, carbon monoxide (CO) and oxides of
nitrogen (NOx) contribute to engine emissions.
They, too, are formed during the combustion proc-
ess and discharged into the exhaust system.
To reduce these pollutants, your Porsche is
equipped with a precisely calibrated fuel injection
system to assure a finely balanced air/fuel mixture
under all operating conditions.
Oxygen sensor The oxygen sensor, installed in the exhaust pipe
continuously senses the oxygen content of the
exhaust and signals the information to an electron-
ic control unit. The control unit corrects the air/
fuel ratio, so the engine always receives an accu-
rately metered air/fuel mixture. Crankcase ventilation Through crankcase ventilation, undesirable emis-
sions from the engine crankcase are not permit-
ted to reach the outside atmosphere. These emis-
sions are recirculated from the crankcase to the
air intake system. From here the emissions mix
with the intake air and are later burned in the en-
gine. Catalytic converters The catalytic converters are efficient “clean-up”
devices built into the exhaust system of the vehi-
cle. The catalytic converters burn the undesirable
pollutants in the exhaust gas before it is released
into the atmosphere.
The exclusive use of unleaded fuel is critical-
ly important for the life of the catalytic con-
verters. Therefore, only unleaded fuel must
be used. The catalytic converters will be damaged by:
– push or tow starting the vehicle
– misfiring of the engine
– turning off the ignition while the vehicle is mov-
ing or
– driving until the fuel tank is completely empty
– by other unusual operating conditions.
fDo not continue to operate your vehicle under
these conditions, since raw fuel might reach
the catalytic converters. This could result in
overheating of the converters. Federal law pro-
hibits use of leaded fuel in this car.

Automatic car washes
Optional add-on parts or parts which project
beyond the contours of the vehicle may be
damaged by design features (e.g. brushes) of au-
tomatic car washes.
The following parts are particularly
susceptible to damage:
– Convertible top (hot wax treatment cannot be
used, as the wax attacks the convertible top
material)
– Windshield wipers (always switch them off to
prevent them wiping unintentionally in intermit-
tent or sensor operation)
– External antennas (always unscrew)
– Roof Transport System (always remove com-
pletely)
–Rear spoiler
– Wheels (the wider the rim and the lower the tire
height, the greater the risk of damage)
– High-gloss wheels (to prevent these from get-
ting scratched, do not clean with the wheel-
cleaning brushes of the car wash).
fPlease consult the operator before using auto-
matic car washes.
fWash and dry by hand all points not reached by
a car wash, such as door and lid seams or
door sills. Note
Automatic car washes spray water at odd angles
and high pressures, which are not seen in normal
driving. Therefore, water can sometimes find its
way into the passengers compartment during or
shortly after the car wash.
Door lock fTo prevent the door lock from freezing during
the cold season, the lock cylinder should be
covered during a wash.
fShould the lock freeze, use an ordinary de-icer.
In many cases, a well warmed key can help.
Never use excessive force.
