Seat adjustment for the passenger's seat
Danger!
Safety belts only offer protection when the
backrest is upright and the belts are properly
positioned on the body. Improperly positi-
oned safety belts can cause serious personal
injury or death in an accident.
fDo not operate the car with the driver or
passenger backrests excessively reclined.
fPorsche recommends the use of L.A.T.C.H.
(Lower Anchorage and Tether for Children)
equipped Porsche child seat.
Do not install a child restraint system in
the Sports bucket seat.
The Sports bucket seat cannot be equipped with the LATCH system.
If the seat is in an extreme position (e.g., the
backrest is in contact with the engine compart-
ment wall), the backrest can warp. Warping of the
backrest can lead to malfunctions.
fCorrect the seat adjustment.
Ensure that the seat is not jammed and is self-
supporting.
Ensure that the backrest is in the upright
position.fDo not transport a load and objects behind and
under the passenger's seat.
If the load or objects are under the seat, it can
cause malfunctions.
If the weight on the passenger's seat is reduced
significantly, e.g., by supporting weight on the
armrest, the passenger's airbag can be switched
off.
fSelect an upright seat position, and do not
support weight on the armrests or lean out of
the window.
Always keep feet in the footwell while driving.
Do not put feet on the dashboard or the seat
area. Do not lean against the inside of the door
or outside the window while the vehicle is
moving.
If the passenger's seat is warped significantly, a
message is displayed on the on-board computer:
fCorrect the seat adjustment.

Operation, Safety
Brake booster The brake booster assists braking only when
the engine is running.
When the car is moving while the engine is not
running, or if the brake booster is defective, more
pressure on the brake pedal is required to bring
the car to a stop.
If this happens, ABS and PSM will also not
operate.
Moisture or road salt on brakes affects braking.
Brakes will dry after a few cautious brake applica-
tions.
Warning!
Risk of an accident, resulting in serious
personal injury or death.
Driving through water may reduce the
traction.
Moisture on brakes from road water, car
wash, or coating of road salt may affect
braking efficiency.
fCautiously apply brakes to test brakes after exposure to road water, etc.
Brake wear Your car has excellent brakes, but they are still
subject to wear. The rate at which they wear
depends on how the brakes are used.
fHave the brake system inspected at the
intervals recommended in your Maintenance
Booklet.
Brake system warning light
You can check the functionality of the brake
system warning light by switching the ignition to
the “On” position and verifying that the warning
light illuminates.
If the warning lights in the instrument panel and on-
board computer stay on when the engine is
running or come on while driving, the brake pads
are worn excessively.
fDo not continue to operate the vehicle.
Have your authorized Porsche dealer inspect
or replace the brake pads.
Brake pads Wear on the brake pads and brake discs depends
to a great extent on the driving style and the condi-
tions of use and therefore cannot be expressed in
actual miles on the road.
The high-performance brake system is designed
for optimal braking effect at all speeds and tempe-
ratures.
Certain speeds, braking forces and ambient
conditions (such as temperature and humidity)
therefore might cause “brake noises”. This also
applies after completion of the breaking-in period
required for the new brake components.
New brake pads or linings
New brake pads and brake discs have to be
“broken in”, and therefore only attain optimal
friction when the car has covered several hundred
miles or km.
The slightly reduced braking ability must be
compensated for by pressing the brake pedal
harder. This also applies whenever the brake pads
and brake discs are replaced.

Operation, Safety When the ignition is switched on the ABS warning
light will light up while the system is electronically
interrogated and goes out when the engine is
started if the check is not yet complete.
If the ABS warning lamp fails to go out, this
indicates that ABS has been deactivated due to a
fault. If the warning lights in the instrument panel
and on-board computer light up while you are
driving, this indicates that a fault has occurred. In
both cases, normal braking, as in vehicles without
ABS, is still retained.
The ABS system should, however, be examined at
an authorized Porsche dealer immediately to
prevent the occurrence of further faults.
fIf the ABS system becomes inoperative, take
your vehicle to your authorized Porsche dealer
immediately.
Warning!
Risk of an accident, resulting in serious
personal injury or death.
The control unit of the ABS brake system is
set for standard tire size. If non-standard
tires are installed, the control unit may misin-
terpret the speed of the vehicle, because of
the variant data it receives from the sensors
on the axles.
fUse only tire makes and types tested by Porsche.

Porsche Stability Management
(PSM)PSM is an active control system for stabilization of
the vehicle during extreme driving maneuvers.
Warning!
Risk of an accident, resulting in serious
personal injury or death.
The increased control that is provided should
not induce you to take greater risks with your
safety. The limits dictated by the laws of
physics cannot be overcome, even with PSM.
The risk of accidents due to inappropriate
speed cannot be reduced, even by PSM.
The driver bears the responsibility for all
driving maneuvers.
fAdapt your driving style to the prevailing road
and weather conditions.
fObey all traffic laws.
Sensors at the wheels, brakes, steering system
and engine continuously measure:
–Speed
– Direction of travel (steering angle)
– Lateral acceleration
– Rate of turn about the vertical axis
– Longitudinal accelerationPSM uses these values to determine the direction
of travel indicated by the driver.
PSM intervenes and helps to correct the course if
the actual direction of motion deviates from the
chosen course (steering-wheel position):
It brakes individual wheels as needed. In addition,
the engine power may be manipulated in order to
stabilize the vehicle.
The events below inform the driver of PSM control
operations and warn him/her to adapt his/her
driving style to the road conditions:
– The multifunctional information light on the
instrument panel flashes.
– Hydraulic noises can be heard.
– The vehicle decelerates and steering-wheel
forces are altered as PSM controls the brakes.
– Reduced engine power.
– The brake pedal pulsates and its position is
changed during braking.
In order to achieve full vehicle deceleration,
foot pressure must be increased after the
brake pedal has begun vibrating.
Advantages of PSM– Improved traction and lane-holding ability in all
driving situations – even on road surfaces with
varying friction.
– The system compensates for undesired lateral
vehicle reactions when the driver releases the
accelerator pedal or brakes when cornering.
This compensation functions up to the
maximum lateral acceleration.
– PSM actively helps stabilize the vehicle as
required during dynamic driving maneuvers
(e.g. rapid steering movements, during lane
changes or on alternating bends).
– Improved braking stability in curves and on
different or varying road surfaces.

Operation, Safety Readiness for operation
PSM is switched on automatically every time you
start the engine.
PSM should always be switched on during
“normal” driving.
However, it may make sense to switch off PSM
temporarily in exceptional situations, for example:
– On a loose surface or in deep snow,
– when “rocking the vehicle free” and
– when using snow chains.
Switching off PSMPSM can be switched off in 2 stages:
– Stage 1 SC OFF:
Switch off Stability Control (SC).
– Stage 2 SC+TC OFF:
Also switch off Traction Control (TC).
Danger!
There is a risk of accident due to loss of
control of the vehicle. There is no stabilizing
brake control in either switch-off stages
(even when the brakes are used).
fPSM should always be switched on during
“normal” driving. This particularly applies in wet conditions.
Switching off Stability Control (SC)Precondition:
The light-emitting diode in the SC+TC OFF button
must be off.
fPress SC OFF button.
Stability Control is switched off after a short
delay.
The light-emitting diode in the button is lit up.
When the system is switched off, the multi-
functional PSM light on the instrument panel
is lit and the message “SC OFF” appears
continuously on the on-board computer.
An acoustic signal also sounds.
– When Stability Control is switched off, sportier
Traction Control is activated.
– Brake control is deactivated.
– The ABS remains active.Switching Stability Control (SC) back onfPress SC OFF button.
Stability Control is switched on after a short
delay.
The light-emitting diode in the button and the
multi-functional PSM light on the instrument
panel go out.
The on-board computer shows a message.

Operation, Safety
Sport modeWhen the Sport mode is switched on, the exhaust
gas back pressure in the lower and middle ranges
is reduced in the variable exhaust system. This
serves to produce a marked increase in torque in
the engine speed range from approx. 3000 rpm
and 4000 rpm. The best values for vehicle accele-
ration and low-end torque are achieved when
Sport mode is switched on.
Switching Sport mode on and off
fPress button in the centre console.
When Sport mode is switched on, the light-
emitting diode in the button is lit.
Note on operation
After the ignition is switched off, Sport mode is
automatically reset to Normal mode.10_GT3_21.book Seite 62 Donnerstag, 4. Juni 2009 12:48 12
