Rain sensorThe rain sensor on the windshield measures the
amount of rainfall (snowfall too). Wiper speed is
automatically adjusted accordingly.
Switching on
fMove wiper lever upwards to the first click.
Switching off
fMove wiper lever to position 0.
The rain sensor remains switched off if the wiper
lever is already in position 1 when the ignition is
switched on.To switch the rain sensor on again:
fMove wiper lever to position 0 and then to
position 1 or
fOperate windshield washer system 5 or
fChange the sensitivity of the rain sensor with
four-stage switch A.
Switch-on is confirmed by one wipe of the
windshield.
On vehicles with the Sport Chrono Package Plus,
further rain sensor functions can be selected via
the PCM.
fPlease see the chapter “Individual Memory” in
the separate PCM Owner’s Manual.
Changing the sensitivity of the rain sensor
Sensitivity can be set with switch A in 4 stages:
fAdjust switch A upwards –
high sensitivity.
The setting is confirmed by one wipe of the
windshield.
fAdjust switch A downwards –
low sensitivity.Maintenance note
fPeriodically clean the wiper blades with a
window cleaner, especially after the vehicle
has been washed in a car wash. We recom-
mend Porsche window cleaner. If they are very
dirty (e.g. with insect remains), they can be
cleaned with a sponge or cloth.
If the wiper blades rub or squeak, this may be as
a result of the following:
– If the vehicle is washed in an automatic car
wash, wax residues may be adhering to the
windshield. These wax residues can only be
removed by using a window cleaner concen-
trate.
fPlease see the chapter “WASHER FLUID” on
Page 170.
fPlease contact your authorized Porsche dealer
for further information.
– The wiper blades may be damaged or worn.
fReplace damaged wiper blades as soon as
possible.

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
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Automatic control is no longer active.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
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 decre-
ased.
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.

Warning!
Your vehicle has also been equipped with a Tire
Pressure Monitoring (TPM) malfunction indicator
when the system is not operating properly.
The TPM malfunction indicator is combined with a
low tire pressure telltale.
When the system detects a malfunction, the
telltale will flash for approx. one minute and then
remain continuously illuminated. This sequence
will continue upon subsequent vehicle start-ups as
long as the malfunction exists.
When the malfunction indicator is illuminated, the
system may not be able to detect or signal low tire
pressure as intended.
TPM malfuntions may occur for a variety of
reasons, including the installation of replacement
or alternate tires or wheels on the vehicle that
prevent the TPM from functioning properly.
Always check the TPM malfunction telltale after
replacing one or more tires or wheels on your
vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPM to continue to
function properly.The warning light in the speedometer lights up:
– When a loss in pressure has been detected.
– When learning newly mounted wheels/wheel
sensors, as long as the vehicle’s own wheels
have not yet been recognized.
In the event of a defect in Tire Pressure Monitoring
or a temporary fault, the warning light in the
speedometer flashes for approx. one minute and
then remains continuously illuminated.
The tire pressure warning light in the instrument
panel goes out only when the cause of the fault
has been rectified.
Partial monitoringMonitoring of the other wheels is continued if there
is a fault in one or two wheel transmitters.
– The tire pressure warning light lights up.
– The message “TPM partial monitoring” is
displayed on the on-board computer.
– No tire pressures are displayed on the on-
board computer for wheels with faulty wheel
transmitters.
No monitoringIn the event of faults the Tire Pressure Monitoring
cannot monitor the tire pressure.
The warning light on the instrument panel flashes
for approx. one minute and then remains conti-
nuously illuminated and a corresponding message
appears on the on-board computer.
Monitoring is not active when:
– the Tire Pressure Monitoring is faulty,
– wheel transmitters for the Tire Pressure
Monitoring are missing,
– during the learning phase after the tire settings
have been updated,
– after a wheel change without updating the tire
settings,
– more than four wheel transmitters are
detected,
– there is external interference by other radio
sources, e.g. wireless headphones,
– tire temperatures are too high.

INSTRUMENT PANEL AND THE ON-BOARD
COMPUTER” on Page 148.
