Operation, Safety
When the ignition is switched on the ABS warning
light will light up while the system is electronically
interrogated and goes o
ut when the engine is
started if the check is not yet complete.
If the ABS warning lamp fails to go out, this indi-
cates 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 driv-
ing, 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 pre-
vent the occurrence of further faults.
f If the ABS system becomes inoperative, take
your vehicle to your authorized Porsche dealer
immediately.
Warning!
Risk of an accident, resulting in serious per-
sonal 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 mis-
interpret the speed of th e vehicle, because of
the variant data it rece ives from the sensors
on the axles.
f Use only tire makes and types tested by Porsche.
Clutch Pedal The clutch pedal must be depressed fully
before the starter will engage.
Warning!
Risk of an accident, resulting in serious per-
sonal injury or death.
f Always check the movement of the clutch ped-
al before driving and make sure that it is not
obstructed by a floor mat or any other object.
f Secure the floor mat to prevent it from sliding
into positions that could interfere with the safe
operation of your vehicle.
Your Porsche dealer will be glad to offer you
nonskid floor mats of the correct size.
To avoid damage to the clutch and transmis-
sion:
f Always depress the clutch pedal fully when
changing gears.
f Do not hold the car on a steep grade with the clutch pedal partially depressed.
Should the free travel of the clutch pedal suddenly
become larger, it could me an a malfunction of the
clutch.
f See your Porsche dealer for correction.

Porsche Stability Management
(PSM)PSM is an active control system for stabilization of
the vehicle approaching the performance limits of
driving maneuvers.
Warning!
Risk of an accident, resulting in serious per-
sonal 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.
f Adapt 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 acceleration PSM 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 in
formation light on the
instrument panel flashes.
– Hydraulic noises can be heard.
– The vehicle decelerate s and steering-wheel
forces are altered as the 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.
Examples of PSM control operations– If the front wheels of the vehicle drift on a
bend, the rear wheel on the inside of the bend
is braked and the engine power is reduced if
necessary.
– If the rear of the vehicle swings out on a bend, the front wheel on the outside of the bend is
braked.Additional braking functions– Pre-filling the brake system:The brake system is prepared for possible
subsequent emergency braking if the acceler-
ator pedal is released suddenly and quickly.
The brake system is prefilled and the brake
pads are already applied gently to the brake
discs.
– Brake booster: In the event of an emergency braking operation
where the pedal force is insufficient, a brake
booster provides the braking pressure neces-
sary for maximum deceleration at all 4 wheels.Advantages of PSM– Best possible traction and lane-holding ability in all driving situations – even on road surfaces
with varying friction.

64
Operation, Safety
– 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 stabilizes the vehicle as required during dynamic driving maneuvers (e.g. rapid
steering movements, during lane changes or
on alternating bends).
– Improved braking stability on bends and on different or varying road surfaces.
– It improves braking function and shortens stopping distance in the event of emergency
braking.
Readiness for operationPSM is switched on automatically every time you
start the engine.
PSM should always be switched on during
“normal” driving.
However, it may be advantageous 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 PSMf Press PSM OFF button.
PSM is switched off after a short delay.
The light-emitting diode in the button is lit up.
When the PSM is switched off, the PSM multi-
functional light on the instrument panel is lit
and a message is shown on the on-board
computer.
An acoustic signal also sounds.
Note
When PSM is switched off, the additional braking
functions are deactivated. Automatic reactivation
in emergency situations is linked to the PSM
control. The following functions stabilize the vehicle in
emergency situations, even with PSM switched
off:
– When PSM is off, the vehicle is stabilized as
soon as one of the two front wheels enters the
ABS control range.
– When PSM is off and Sport mode is on, the vehicle is stabilized as soon as both front
wheels enter the ABS control range.
One-sided spinning of the wheels is prevented,
even with PSM switched off.
Switching PSM back onf Press PSM OFF button.
PSM is switched on after a short delay.
The light-emitting diode in the button and the
PSM multifunctional li ght on the instrument
panel go out.
The on-board computer shows a message.

Operation, Safety

Sport modeA sportier car set-up is obtained when Sport or
Sport Plus mode is switched on.
PSM interventions are later than in Normal mode;
the vehicle can be maneuverd with greater agility
at its performance limits, without dispensing with
the assistance of PSM in emergency situations.
This helps to achieve optimal lap times, particu-
larly on race circuits and a dry road surface.
– The multifunctional light on the instrument panel lights up for a lamp check when the
ignition is switched on.
– The light indicates a control operation by flashing, including when PSM is switched off
(brake control in the ev ent of one-sided wheel
spin).
– In conjunction with a message on the on-board computer, the light indicates that PSM is
switched off.
An acoustic signal also sounds.
– The light indicates a faul t in conjunction with a
message on the on-board computer.
PSM is out of order. f
Please have the fault remedied at an author-
ized Porsche dealer.
