cooling PORSCHE 911 GT3 2010 5.G Owners Manual

6Service brakeBoth the standard brake system with composite
brake discs and the Porsche Ceramic Composite
Brake (PCCB) are high-performance brake
systems, designed specifically for driving on race
circuits.
Certain speeds, braking forces and ambient condi-
tions (e. g. temperature and humidity) therefore
might cause brake noises. This also applies after
completion of the running-in phase required for the
new brake components.
Wear on the different components of the braking
system, such as brake pads and brake discs,
depends to a great extent on the individual driving
style and the conditions of use and therefore
cannot be expressed in actual miles on the road.
The values communicated by Porsche are based
on normal operation adapted to traffic. Wear incre-
ases considerably when the vehicle is driven on
race tracks or through an aggressive driving style.
fPlease consult an authorized Porsche dealer
about the current guidelines in effect before
such use of your vehicle.
Aerodynamic componentsTo benefit from the high driving performance
without impairing the driving safety or the service
life of the vehicle components, certain vehicle
parts must be always fully operational while
driving.
fRegularly check your vehicle for signs of
damage.
Damaged, worn or missing aerodynamic
components such as spoilers or underside
panels affect driving behaviour and must there-
fore be replaced immediately.
To optimize the cooling of the brake discs, air
brake spoilers are fitted to the front and rear
running gear control arms as well as special air
brake ducts on the rear axle.
If these air-brake spoilers or air-brake ducts are
not fitted and there is a high thermal demand on
the braking system, the service life of the brake
discs could be reduced.
Brake wear expectations are based on normal
operations in street traffic. Wear increases consi-
derably when the vehicle is driven on race tracks
or with an aggressive driving style. Wear will also
increase considerably if the brakes are not
warmed up before being raced.
The aerodynamic stability of the vehicle is influ-
enced considerably at high speeds by the front lip.Due to the reduced ground clearance required for
optimization of road handling, the front lip and the
air-brake spoilers have to be placed in exposed
positions to fulfil their function. They can be
damaged, for example by ground or curbstone
contact.
SeatingYour car has two seats.
The area behind the seats is not intended for
passengers.
Danger!
In the event of an accident, serious personal
injury or death can result.
fNever allow anyone to sit in the area behind the
seats.
Persons occupying the area to the rear of the
two seats will not have a safety belt or airbag
protection, and in the event of an accident,
would be thrown around within or to the
outside of the vehicle compartment with
probable serious personal injury or death as the result.

Operation, Safety
65
Lowering front axle fPress button in the center console.
The vehicle is lowered to the basic level.
The light-emitting diode in the button and in the
tachometer goes out.
Caution!
Risk of damage through bottoming out the
vehicle.
fDo not lower the vehicle when it is positioned above an obstacle.
Notes on operation
Warning messageFront axle lift system faults are indicated by
a warning message on the on-board computer.
fPlease see the chapter “WARNINGS ON THE
INSTRUMENT PANEL AND THE ON-BOARD
COMPUTER” on Page 148.
– When raised, the damping properties of the
front axle change and noise may be heard in
the area of the front axle coil springs during
steering movements.
– The doors must be closed when lowering the
front axle.
–The blowing-off procedure may result in
system-related hissing noise. This does not
represent a malfunction in the lift system.– During extended vehicle immobilization, the
pressure accumulator may be completely
emptied. In this case, the first time the axle is
raised, a period of up to 2 minutes may elapse
before the vehicle height is reached and “LIFT”
is displayed.
– A flashing LED in the button indicates that the
system is currently not available. Possible
causes may be:
> Automatic overload protection is active.
The system will be available again
following a brief cooling-down phase.
The cooling-down phase may be
extended when outside temperatures
are very high.
> The speed threshold of 30 mph
(50 km/h) has been exceeded. The
system will be available again once the
speed falls below the threshold.
> If automatic lowering is actuated by
exceeding a speed of approx. 30 mph
(50 km/h) in combination with hard
acceleration, the required lowering
duration may mean that “LIFT not
lowered” is displayed. The display goes
out again as soon as the front axle has
been completely lowered.

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.

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

Coolant LevelfPlease see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on Page 157.
The cooling system is filled at the factory with a
permanent coolant.
It provides year-round protection from corrosion
and freezing down to –31 °F/–35 °C
.
fOnly use antifreeze authorized by Porsche.
Checking coolant level The expansion tank with its filler orifice is in the
left-hand side of the engine compartment.
fCheck the coolant level regularly through the
transparent expansion tank.
When the engine is cold and the car is level the
fluid level must lie between the “MIN” and “MAX”
markings. Topping off coolant
Warning!
Danger of serious personal injury or death
from scalding. Coolant is hazardous to your
health, and may be fatal if swallowed.
fDo not open the cap of the expansion tank
while the engine is hot.
fAllow the engine to cool down before opening
the cap and protect your hands, arms and face
from any possible escape of hot coolant.
fKeep coolant out of children’s reach.
fAlso, keep coolant away from your pets.
They can be attracted to it should there be a
spill, or to used coolant left in an open
container. Coolant can be deadly to pets if consumed.1. Switch engine off and let it cool.
Please see the chapter “COOLING SYSTEM” on
Page 112.
2. Cover the expansion tank cap with a thick rag.
Open cap slowly and carefully and allow
overpressure to escape.
Then unscrew cap completely.
3. Only add a mixture of antifreeze and water in
equal parts, and do not exceed the “MAX”
mark.
Antifreeze in coolant:
50% gives protection down to –31 °F/–35 °C
60% gives protection down to –58 °F/–50 °C
4. Screw cap firmly on.
If in an emergency pure water has been added, the
mix ratio must be corrected at an authorized
Porsche dealer.
Marked loss of coolant indicates leakage in the
cooling system.
The cause should immediately be remedied at an
authorized Porsche dealer.
