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Automatic control is no longer active.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:
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
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.

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.
fAlways 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
fIf 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 “A”(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.
fWhen the gear shift indicator A lights up,
change to the next higher gear to decrease
fuel consumption.

Level gage

When the ignition is on the fuel level is displayed.
fPlease see the chapter “CAPACITIES” on
Page 290.
If the vehicle’s inclination changes (e.g. going up
or downhill), minor deviations in the indication may
occur. Note
If a small quantity of fuel is added to a nearly emp-
ty fuel tank, the fuel gage cannot measure the add-
ed fuel accurately. The „remaining range“ readout
will also be incorrect.
Warning light “A” When the engine is running, the warning light
of the level gage lights up if less than approx.
2.6 U.S. gallons (10
liters) of fuel remains in the
tank.
Additionally, a warning is displayed in the on-board
computer.
fFill up at the next opportunity.
Caution!
To prevent damage to the emission control
system and engine.
fNever drive the tank completely out of fuel.
fAvoid high cornering speeds after the warning lights have come on.
fPlease see the chapter “EMISSION CONTROL
SYSTEM” on Page 218.If the level gage warning light flashes, there
has been a system fault.
Additionally, a warning is displayed in the on-board
computer.
There will then be no reserve warning.
fTo remedy the fault, go to an authorized
Porsche dealer.

Check Engine
(Emission Control)The emission control system detects malfunctions
early that could, for example, cause increased
pollutant emissions or consequential damage.
Faults are indicated by a continuously lit or
flashing instrument panel warning light.
The faults are recorded in the control unit's fault
memory.
The warning light in the instrument panel lights up
when the ignition is switched on as a bulb check
and goes out approx. 4 seconds after the engine
starts. If the warning light does not light up, have
the bulb replaced promptly.
The warning light in the instrument panel flashes to
indicate operating states (e.g. engine misfiring)
which might cause damage to certain parts of the
emission control system.
fIn this case, immediately reduce the engine
load by easing off the accelerator.
fIn order to avoid consequential damage to the
engine or emission control system (e.g. cata-
lytic converter), have the fault diagnosed and
rectified immediately at the nearest authorized
Porsche dealer.If the warning light in the instrument panel lights up
permanently without flashing before and remains
on while driving, it suggests:
– a potential engine control problem and the
need for system service or
– an improperly fastened tank cap or
– the vehicle was refueled while the engine was
running.
fStop immediately at a suitable and secure
place and check tank cap for proper fastening.
If tank cap was fastened correctly, see your au-
thorized Porsche dealer for service as soon as
possible.
Caution!
If the check engine warning light in the in-
strument panel is flashing, serious catalytic
converter damage and power loss will soon
occur.
Prolonged driving with the check engine war-
ning light on could cause damage to the
emission control system. It also could affect
fuel economy and driveability.
fHave the fault remedied at the nearest authorized Porsche dealer immediately.The central warning light on the instrument panel
lights up if there are warning messages in the
INFO menu.
The messages can be called in the on-board
computer INFO menu:
fPlease see the chapter “INFO WARNING MES-
SAGES” on Page 132.
The warning light on the instrument panel lights
up:
– if the handbrake is on,
– if the brake fluid level is low,
– if the brake pads have reached the wear limit,
– if the brake circuit division is defective.
Additionally, a warning is displayed by the on-
board computer.
fPlease see the chapter “WARNINGS ON THE
INSTRUMENT PANEL AND THE ON-BOARD
COMPUTER” on Page 158.
