Controls, Safety, Instruments The voltmeter indicates the battery voltage.
Normal range: 12 to 16 volts.
The voltage may drop considerably when the
vehicle is being started.
If the indicator is continually below 12 volts
when the engine is running:
fPlease have the battery charging system
checked at an authorized Porsche dealer.
Battery/alternatorA warning message will appear on the multi-pur-
pose display of the instrument panel if the voltage
drops significantly.
fStop in a safe place and switch off the engine.
Possible causes
– Defect in the battery charging system
– Broken drive belt
Warning!
Risk of accident and risk of engine damage.
A broken drive belt means there is no power
assistance to the steering (more effort is re-
quired to steer) and engine cooling fails.
fDo not continue driving.
fHave the fault remedied at your nearest autho-
rized Porsche dealer.
Danger of steering assistance failing during
a long journey in the water if the drive belt
slips.
fIf the steering assistance fails, more effort will be required to steer.

General informationRange on remaining fuel
The range on remaining fuel is continuously
recomputed while driving based on fuel level,
current consumption and average consumption.
Average speed
The displayed values are based on the distance
travelled since the last reset to “zero”.
Note on operation
Switching the ignition off does not reset the
measurements. Values can thus be collected over
long periods. Disconnecting the vehicle battery
clears the memories.
Further on-board computer functions can be dis-
played in the PCM.
Please follow the separate operating instructions
for PCM.

ECON modeThe outside air that is flowing in does not dry up if
the air-conditioning compressor is switched off.
Warning!
Risk of accident due to hampered vision.
If the air-conditioning compressor is
switched off, the windows may mist up.
fDo not switch off the air-conditioning compres-sor in damp weather.
Switching air-conditioning compressor off
Whenever outside temperatures exceed 37.4°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 ECON button M.
The ECON logo appears on the air-conditioning
display panel.
The air-conditioning compressor is switched
off.
Switching air-conditioning compressor on
fIf the interior temperature is too high:
Press ECON button Mor
Press AUTO button C.
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
