for longer than 60 seconds (upward slopes).
– For PSM control operations.
Resuming the stored speed f Briefly push operating lever upwards
(position 4).
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 f Press button A on the automatic speed control
lever.
The green readiness light in the speedometer
goes off.
Note

Car Telephone and
Aftermarket Alarms Important legal and safety information
regarding the use of cellular telephones
Some states may prohibit the use of cellular tele-
phones 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.
Severe 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 seri ous or fatal injury.
When using your cellular telephone, you should al-
ways:
f Give full attention to your driving - pull off the
road and park before making or answering a
call if traffic conditions so require; and
f Keep both hands on the steering wheel - use
hands-free operation (if available) - pull off the
road and park before using a hand-held tele-phone. 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 tele phone with a transmitting
antenna inside the car may cause the warning
lights to come on.
Improper installation of such equipment can cre-
ate a discharged battery or excessive current
draw from added equipment. If aftermarket systems are
installed by non-dealer-
ship technicians or outside the selling dealer,
problems may result. Installation of aftermarket
equipment is not covered under the New Car War-
ranty.
f Consult your authorized Porsche dealer about
the installation of non Porsche approved equip-
ment.
Reception quality
The reception quality of your car telephone will
change constantly when you are driving. Interfer-
ence caused by buildings, landscape and weather
is unavoidable. It may become particularly difficult
to hear when using the hands-free function due to
external noise such as engine and wind noise.
Automatic car-wash
f Unscrew external antennas before using an au-
tomatic car-wash.

Automatic air conditioning system, Heated rear window/Door mirror heating
Information on air-conditioning
compressor– May switch off briefly to ensure sufficient engine cooling if the engine is operating under
extreme load.
– The air-conditioning compressor switches off automatically at temperatures below approx.
37 °F/3 °C and cannot be switched on, even
manually.
– 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 hu- midity, condensation can drip from the evapo-
rator 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 auth orized Porsche dealer
for further information.

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.
f Always 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
f If 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(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.
f When the gear shift indicator A lights up,
change to the next higher gear to decrease
fuel consumption.
