regarding the use of cellular telephones
Some states may prohibit the use of cellular
telephones while driving a vehicle. Check the laws
and regulations on the use of cellular telephones
in the areas where you drive.
Danger!
Risk of an accident.
Serious personal injury or death can result in
the event of an accident.
Looking away from the road or turning your
attention away from your driving can cause
an accident and serious or fatal injury.
When using your cellular telephone, you should
always:
fGive full attention to your driving - pull off the
road and park before making or answering a
call if traffic conditions so require; and
fKeep both hands on the steering wheel - use
hands-free operation (if available) - pull off the
road and park before using a hand-held telephone. It is essential to observe the telephone
manufacturer's instructions before operating
the telephone.
Any portable telephone or radio transmitter which
is used in a Porsche must be properly installed in
accordance with the technical requirements of
Porsche.
The transmission power must not exceed
10 W.
The devices must possess a type approval for
your vehicle and have an “e” symbol.
If you should require equipment with transmission
power values greater than 10 W, please consult
your authorized Porsche dealer for this purpose.
The dealer is familiar with the technical require-
ments for installing devices of this kind.
The antennas for all radios and telephones with a
transmitting antenna must be externally mounted.
The improper installation of radios or telephones
or use of a radio or telephone with a transmitting
antenna inside the car may cause the warning
lights to come on.
Improper installation of such equipment can
create a discharged battery or excessive current
draw from added equipment.

A- Light-emitting diode for status identificationHomeLinkThe programmable HomeLink replaces up to three
original hand-held transmitters used to operate
various devices (e.g. garage door, gate to the
property, alarm system).
You can program buttons 1 to 3 with a frequency
of an original handheld transmitter.

Otherwise, range restrictions cannot be ruled
out.
fBefore selling the vehicle, delete the
programmed signals of the HomeLink.
fPlease read the instructions for the original
hand-held transmitter to find out whether the
original transmitter is equipped with fixed or
changeable code.
fAlways fit new batteries in your hand-held trans-
mitter before programming the transmitter.
Allocating signals to the buttonsfPlease follow the operating instructions for the
original hand-held transmitter.

Recommendation: 72 °F/22 °C.
If “LO” or “HI” appears on the display, the system
is operating at maximum cooling or heating
power.
Automatic control is no longer active.
Note
If the preselected temperature is changed, the
blower speed can increase automatically in
automatic mode.
The desired temperature is reached more quickly
this way.
Sensors
To avoid affecting the performance of the air-
conditioning 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

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.
