Decelerating Option 1
fPull operating lever towards the steering wheel
(position 2) until the desired speed is reached.
The speed reached is maintained and stored
when the lever is released.
Option 2
fBriefly move lever towards the steering wheel
(position 2) (a maximum of 10 times).
The speed is reduced by 1 mph (1.6 km/h)
each time.
Interrupting automatic speed control
operation fPull operating lever downwards briefly
(position 3) or
fOperate brake or clutch pedal or
fSwitch Tiptronic transmission to selector lever
position N.
fPlease observe the chapter “TIPTRONIC S” on
Page 147.
The speed driven before the interruption remains
stored in the memory.
Automatic speed control operation is
interrupted automatically:
– If the set vehicle speed is exceeded by more
than approx. 16 mph (25 km/h) for longer than
20 seconds.
– If the actual vehicle speed falls to approx.
6 mph (10 km/h) below the set vehicle speed
for longer than 5 seconds (upward slopes).
– For PSM control operations.
Resuming the stored speed fBriefly push operating lever upwards
(position4).
The speed control accelerates/decelerates
the vehicle to the stored speed.
The stored speed should only be recalled when
traffic conditions and the road surface so permit.Switching automatic speed control
readiness off fPress button A on the automatic speed control
lever.
The green readiness light in the speedometer
goes off.
When the vehicle is parked and the ignition
switched off, the memory is cleared.
Important note
On upward or downward slopes, the set speed
cannot always be maintained by the automatic
speed control.
To obtain sufficient engine braking or a better en-
gine-speed range, therefore, you have to select a
lower gear.

mode off immediately by pressing the
air-circulation button again and selecting the “Defrost windshield” function.
Switching circulating-air mode on or off
fPress circulating-air button C.
The light-emitting diode in the button lights up.

ECO – switching the air-conditioning
compressor 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 can be
switched on or off manually.
The compressor can be switched off manuall to
save fuel.
fPress ECO button E.
The light-emitting diode in the button lights up.
The compressor is switched off.
fIf the interior temperature is too high, switch
on the compressor again.
To dry incoming air in damp weather, do not
switch off the air-conditioning compressor.
This prevents misting of windows.AC max operationIn AC max operation, the interior of your vehicle is
cooled as quickly as possible.
fPress AC max button H.

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°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 D.

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 manually to
save fuel, but control comfort is then limited:
fPress ECO button E.

Information on air-conditioning
compressor– May switch off briefly to ensure sufficient
engine cooling if the engine is operating under
extreme load.
– Operates most effectively with the windows
closed.
If the vehicle has been in the sun for a long
time, it is a good idea to ventilate the interior
briefly with the windows open.
– Depending on the outside temperature and
humidity, 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
temperature has been set, switch off the air
conditioning compressor and have the fault
remedied.
Please contact your authorized Porsche dealer
for further information.

Operational readiness of the emergency flasher
does not depend on the ignition lock and turn sig-
nal lever position.
fIf your car is disabled or parked under emer-
gency conditions switch on the emergency
flasher in the dashboard (arrow).
All turn signals and the indicator light in the
switch flash with the same frequency.
Warning!
Risk of an accident.
fWhenever stalled or stopped for emergency re-
pairs, move the car well off the road. Switch on
the emergency flasher and mark the car with
road flares or other warning devices.
fDo not remain in the car. Someone approa-
ching from the rear may not realize your vehic-
le is stopped and cause a collision.
Danger of fire.
fDo not park or operate the vehicle in areas
where the hot exhaust system may come in
contact with dry grass, brush, fuel spill or
other flammable material.
Hot engine compartment components can
burn skin on contact.
fBefore working on any part in the engine com-
partment, turn the engine off and let it cool down sufficiently.
