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

Operation, Safety
63
The previously selected PASM mode is always
activated after the engine is started.
There is no automatic return to Normal mode after
the ignition is switched off.
PASM makes two running-gear setups available to
the driver: “Normal” and “Sport”.
The selection is made via a button on the center
console.
When in Normal mode the running gear is in a
basic setup for roads and circuits with “irregular”
surfaces.
Sport mode provides a shock-absorber setting
for particularly high driving dynamics (e.g. on level
circuits).
The variable suspension system selects the appro-
priate damping level for each wheel according to
the situation and conditions of driving.
Example:
If the vehicle is driven in a very sporty manner in
Normal mode, PASM automatically adapts the
shock-absorber behavior to the driving situation
accordingly.
Switching on PASM Sport modefPress PASM button in the center console.
When PASM Sport mode is switched on, the
light-emitting diode in the button is lit up and a
message is shown on the on-board computer.Switching off PASM Sport modefPress PASM button in the center console.
The light-emitting diode in the button goes out
and the on-board computer displays a
message.
Dynamic Engine Mounting (PADM)The dynamic engine mounting with variable
damping is a system for improving driving
dynamics and enhancing driving comfort.
Depending on the driving situation, the ideal
mounting stiffness and damping is automatically
selected in a range between an almost rigid
connection of the engine to the body (improved
driving dynamics) and a decoupling of the engine
from the body (improved driving comfort).Warning messageDynamic engine mounting faults are indicated by
a warning message on the on-board computer.

Operation, Safety
Front Axle Lift SystemThe front axle lift system enables the body to be
electropneumatically raised at the front by about
1.18 in. (30 mm) (front edge of front spoiler).
This in turn enables damage to the body to be
prevented, which e. g. may occur when driving
into multi-level parking garages with steep ramps
or over speed bumps.Readiness for operationThe front axle lift system is operational when the
engine is running and the vehicle is at a standstill
or up to a speed of approx. 30 mph (50 km/h).
The vehicle is automatically lowered to the basic
level again when a speed of approx. 30 mph
(50 km/h) is exceeded.
Raising front axle fPress button in the center console.
The vehicle is raised at the front axle within
approx. 3 seconds.
When the lift function is activated, the light-
emitting diode in the button is lit.The logo “LIFT” also appears next to the digital
speedometer when the front axle is fully raised.
Caution!
Risk of damage through uncontrolled
lowering of the front axle at engine standstill.
In this particular system, the retaining
position cannot be maintained in the upper
position over an extended period without
active replenishing of the pressure accumu-
lator or engine operation.
fAlways park the vehicle in the lowered position.
