Environmentally friendly vehiclesModern environmental technology ensures compli-
ance with all emission laws applicable worldwide.
It has the following advantages:
– Rapid “operational readiness” of the catalytic
converters ensures low emissions, even in
short-trip operation.
– Reliable operation and good emission control
over a long useful life.
fPlease observe the chapter “FUEL ECONOMY”
on Page 258.
Recycling –
for a Porsche, this is virtually an
academic questionMore than two-thirds of all Porsches ever built are
still running.
But, just in case recycling is ever necessary,
we take the following precautionary
measures:
– Utilisation-friendly design.
– Identification of materials.
– Use of recyclable materials.
– Reusable components designed for simple
removal.
Emission control is built inInnovative engine technology combines high
engine performance and environmental compati-
bility.
The engine diagnosis system electronically
monitors the components and systems that affect
exhaust gases.
This continuous monitoring and fault storage
enables swift, reliable diagnosis and fault detec-
tion.
Faults are indicated to the driver by the “Emission
control” warning light and display.
fPlease observe the chapter “EMISSION CONT-
ROL” on Page 79.

Controls, Safety, Instruments 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 stalk to position 0 and then to
position1 – switching on is confirmed by one
wipe of the windscreen – or
fOperate windscreen washer system 5–
switching on is confirmed by three wipes of the
windscreen – or
fChange the sensitivity of the rain sensor with
four-stage switch A.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.
2 – Front windshield wiper – slow
fMove wiper stalk upwards to the second click.
3 – Front windshield wiper – fast
fMove wiper stalk upwards to the third click.
At speeds of less than approx. ca. 2.5 mph
(4 km/h), rain sensor operation mode is automat-
ically activated if the windshield wiper is switched
on. If you exceed a speed of approx. 5 mph
(8 km/h), the system switches to the pre-selected
wiper level.
4 – Front windshield wiper – one-touch oper-
ation
fMove wiper stalk downwards. The front wind-
shield wipers go through one wipe cycle.5 – Front windshield wipers and washer sys-
tem
fPull wiper stalk towards the steering wheel.
The washer system sprays and wipes while the
lever is pulled towards the steering wheel.
When the wiper lever is released, a few drying
wipes are executed.
Headlight washer (on vehicles with Bi-Xe-
non headlights):
The washer sprays only while low beam or high
beam is switched on.
To activate the headlight washer system, the
wiper lever must be pulled for a longer period
of time.
The spray duration is limited.
Maintenance note
fIf heavily soiled, repeat wash.
fPersistent dirt (e.g. insect remains) should be
regularly removed.
Please observe the chapter “CAR CARE IN-
STRUCTIONS” on Page 265.
Thefront windscreen washer nozzles are heat-
ed when the ignition is on, as a precaution against
freezing.

Information on air-conditioning
compressorThe air-conditioning compressor:
– Can switch off briefly if engine is under an ex-
treme load to ensure sufficient engine cooling.
– Switches off automatically at temperatures be-
low approx. 37.4°F (3°C) and cannot be
switched on, even manually.
– Operates most effectively with windows
closed.
If the car has been in the sun for a long time,
however, it is a good idea to ventilate the
interior briefly with the windows open.
Notes on operation
Depending on the outside temperature and humid-
ity, 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 temper-
ature has been set (“LO”), switch off the air-condi-
tioning compressor and have the fault remedied at
an authorized Porsche dealer.
REST modeUsing engine residual heat
The residual heat of the engine can be used to
heat the interior up to 20 minutes after the ignition
has been switched off.
fPress REST button N.
The air-conditioning settings cannot be
changed in REST mode.
Ending the function
fPress REST button N.
Note on operation
If the battery positive voltage is too low, REST
mode is automatically ended.
