2010 PORSCHE 911 GT3 heating

Automatic air conditioning system, Heated rear window/Door mirror heating
99
Setting temperaturefPress button F 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Automatic control is no longer active.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 C.fPress button A (switch on or off).
The windshield is defogged or defrosted as
quickly as possible.
Air flows to the windshield only.
The light-emitting diode in the button lights up.
AC OFF – switching compressor for air-
conditioning system 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 is
always switched on in automatic mode.
The compressor can be switched off to save fuel,
but control comfort is then limited:
fPress AC OFF button D.
The compressor is switched off.
The light-emitting diode in the button lights up.
fIf the interior temperature is too high, switch
compressor back on or press AUTO button.
To dry incoming air in damp weather, do not
switch off the air-conditioning compressor.
This prevents fogging of windows.fPress button K upwards or downwards respec-
tively.
The preset blower speed is increased or decre-
ased.
The speed stages are indicated by a bar display.
If the button is pressed downwards at the lowest
blower stage, the blower and automatic control
are switched off. “OFF” will appear on the display
field.
Pressing the button upwards or pressing the
AUTO button switches the blower and automatic
control back on again.
Warning!
Risk of accident due to impaired vision,
resulting in serious personal injury or death.
In recirculating-air setting, the windows may
fog up.
fOnly select recirculating-air setting for short
periods.
fIf the windows fog up, switch recirculating-air
setting off immediately by pressing the
circulating-air button again and select the “Defrost windshield” function.

fPress button E.
The outside-air supply is interrupted and only
the inside air is circulated.
The light-emitting diode in the button lights up.
Over approx. 37 °F/3 °C
If the air-conditioning compressor was off, it
switches on automatically. The duration of recircu-
lating-air setting is not limited.
Below approx. 37 °F/3 °C
The air-conditioning compressor is switched off.
Recirculating-air setting is automatically ended
after approx. 3 minutes.
Air distributionThe individual air distributions can be combined as
desired.
Recommended setting in Summer:
Air distribution to central and side vents.
Recommended setting in Winter:
Air distribution to footwell and windshield.fPress button H.
The air flows to the footwell.
The selection appears on the display panel.
fPress button I.
The air flows from the central and side vents.
Vents must be open.
The selection appears on the display panel.
fPress button J.
The air flows to the windshield.
The selection appears on the display panel.
Note on operation
fOn vehicles with the Sport Chrono Package
Plus, individual air conditioning settings can be
stored on your vehicle key.
Please see the chapter “Individual Memory” in
the separate PCM Owner’s Manual.
General instructions for air-conditioning
compressor– Can switch off briefly if engine is under an
extreme load to ensure sufficient engine
cooling.
– Switches off automatically at temperatures
below approx. 37 °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, 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 vehicle.
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
repaired at an authorized Porsche dealer. Air distribution to footwell

How Emission Control Works When an automobile engine is running, it uses
energy generated through the combustion of a
mixture of air and fuel. Depending on whether a
car is driven fast or slowly or whether the engine
is cold or hot, some of the fuel (hydrocarbons)
may not be burned completely, but may be
discharged into the engine crankcase or exhaust
system. Additonal hydrocarbons may enter the
atmosphere through evaporation of fuel from the
fuel tank. These hydrocarbons (HC), when
released into the air, contribute to undesirable
pollution.
In addition, carbon monoxide (CO) and oxides of
nitrogen (NOx) contribute to engine emissions.
They, too, are formed during the combustion
process and discharged into the exhaust system.
To reduce these pollutants, your Porsche is
equipped with a precisely calibrated fuel injection
system to assure a finely balanced air/fuel mixture
under all operating conditions.
Oxygen sensor The oxygen sensor, installed in the exhaust pipe
continuously senses the oxygen content of the
exhaust and signals the information to an
electronic control unit. The control unit corrects
the air/fuel ratio, so the engine always receives an
accurately metered air/fuel mixture. Crankcase ventilation Through crankcase ventilation, undesirable
emissions from the engine crankcase are not
permitted to reach the outside atmosphere. These
emissions are recirculated from the crankcase to
the air intake system. From here the emissions
mix with the intake air and are later burned in the
engine. Catalytic converters The catalytic converters are efficient “clean-up”
devices built into the exhaust system of the
vehicle. The catalytic converters burn the undesi-
rable pollutants in the exhaust gas before it is
released into the atmosphere.
The exclusive use of unleaded fuel is criti-
cally important for the life of the catalytic
converters. Therefore, only unleaded fuel
must be used.The catalytic converters will be damaged by:
– push or tow starting the vehicle
– misfiring of the engine
– turning off the ignition while the vehicle is
moving or
– driving until the fuel tank is completely empty
– by other unusual operating conditions.
fDo not continue to operate your vehicle under
these conditions, since raw fuel might reach
the catalytic converters. This could result in
overheating of the converters. Federal law
prohibits use of leaded fuel in this car.

Practical Tips, Emergency Service
Connect jumper cables in the following
sequence: Always observe the sequence below:
1. Connect the positive lead (red) to the
positive terminal of the discharged battery
first, then connect it to the positive terminal of
the donor battery.
2. First connect the negative cable (black) to
the negative terminal of the donor battery, then
connect it to a suitable grounding point on the
vehicle with the discharged battery.
This grounding point must lie as far as possible
from the battery.
For example, a solid metal part or the engine
block are suitable grounding points.
If no suitable grounding points are to be found
on either vehicle, the negative cable must
carefully be connected directly to the negative
terminal of the battery.
If a suitable grounding point is to be found only
on the donor vehicle, the negative cable must
first be connected to the terminal of the
discharged battery, then to the grounding point
of the donor vehicle.
3. Run the engine of the donor car at a higher
speed.4. Start the engine.
An attempted start using jumper cables should
not last more than 15 seconds. Then allow a
waiting period of at least one minute.
fNote
Before disconnecting the jumper cables,
electrical loads such as the heated rear
window and the heating fan blower should be
switched on (the vehicle’s lights must not be
switched on). This reduces voltage peaks
which may occur when disconnecting the
jumper cables.
With the engine running, remove both jumper
cables in reverse order.10_GT3_21.book Seite 218 Donnerstag, 4. Juni 2009 12:48 12
