Temperature gaugePointer below 180°F (80°C) – engine cold
fAvoid high engine speeds and heavy engine
loading.
Pointer between 180°F (80°C) and 260°F
(100°C) – normal operating temperature
Pointer may move up to the red area when engine
is heavily loaded and outside temperature is high.
Engine coolant temperature warningA warning message will appear on the multi-pur-
pose display of the instrument panel if the engine
coolant temperature is too high.
fSwitch engine off and let it cool.
fCheck radiator and air passages in front end of
car for obstructions.
fCheck coolant level.
Add coolant if necessary.
Please have the fault remedied at an autho-
rized Porsche dealer.
fPlease observe the chapter “COOLANT LEVEL”
on Page 249.
Note on operation
To prevent excessive temperatures, the cooling
air guides must not be restricted by covers
(e.g. films, “stone guards”).
Engine coolant level warningA warning message will appear on the multi-pur-
pose display of the instrument panel if the engine
coolant level is too low.
fSwitch engine off and let it cool.
fTop up coolant.
Please have the cause of the fault remedied at
an authorized Porsche dealer.
fPlease observe the chapter “COOLANT LEVEL”
on Page 249.
Caution!
Risk of engine damage.
fDo not continue driving if the warning persists
even when the engine coolant level is correct.
fHave the fault remedied at your nearest autho-rized Porsche dealer.
Cooling System

78
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.

display on the display above the button.
If the air quantity was reduced so much that “OFF”
appears on the display, the outside-air supply is
interrupted.
Warning!
Risk of accident due to hampered vision. If
the air quantity is “OFF”, the windows may
mist up.

quantity blowing out can adjust automatically in au-
tomatic mode.
The desired temperature is reached more quickly
this way.fPush button G up or down to adjust the air
quantity.
The selected air quantity is shown in a bar
display on the display above the button.

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

(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.

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
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.
