Operation, Safety
Seat Adjustment and Head
Restraints
Warning!
The seat may move unexpectedly if you
attempt to adjust while driving. This could
cause sudden loss of control, resulting in se-
rious personal injury or death.
f Do not adjust seats while the vehicle is in mo-
tion.
The backrest locks must be engaged at all
times while the vehicle is in motion.
Safety belts only offer protection when the
backrest is upright and the belts are properly
positioned on the body.
Improperly positioned sa fety belts or safety
belts worn by passengers in an excessively
reclined position can cause serious personal
injury or death in an accident.
f Do not operate the car with the driver or
passenger backrests excessively reclined
(see “Seat position”).
Risk of injury if persons or animals are in the
movement range of the seat during seat
adjustment.
f Adjust the seat so that no-one is put at risk.
Caution!
Risk of damage to windshield, sun visor, etc.
when the seat is adjusted or folded back or
forward.
f Adjust the seat so that the s e a t b a c k re s t i s n o t in contact with any other object.
The driver and passenger seats provide
integrated head restraints in the backrests. The
head restraints are not adjustable. Warning!
All occupants, including the driver, should not
operate a vehicle or sit in a vehicle's seat until the
head restraints and backrests, respectively, are
placed in their proper posi tions so that the risk of
neck injuries is minimize d in the event of a crash.
For proper positioning of the head restraint, the
seatback's inclination should be adjusted such
that the head restraint is in an upright position.
Driver and passenger should be seated upright
and in the center of their seats.
Seat positionAn ergonomically correct sitting position is
important for safe and fatigue-free driving.
We recommend the following procedure for adjust-
ing the driver’s seat to suit individual
requirements:
1. Vehicles with manual transmission:
Adjust the seat until, with the clutch pedal fully
depressed, your leg remains at a slight angle.
Vehicles with Porsche Doppelkupplung
(PDK):
Adjust the seat until, with your left foot on the
footrest, your left leg remains at a slight angle.
2. Rest your outstretched arm on the steering wheel.
Set the backrest angle (not applicable for
Sports bucket seat) and the steering-wheel
position so that your wr ist rests on the outer
rim of the steering wheel. At the same time,
the shoulders must still be in noticeable
contact with the backrest.
3. Adjust the seat height (not applicable for
Sports bucket seat) to give yourself enough
headroom and a good overview of the vehicle.
4. Electrically adjustable seat: Adjust the seat angle until your thighs rest
lightly on the seat cushion.

fUsing accessories not approved by Porsche
can cause the weight sensing system to be im-
paired.
f Do not squeeze objects, such as the fire extin-
guisher, or first aid kit under the seat.
f Only have seats removed and installed by an
authorized Porsche dealer so that weight sens-
ing components will not be damaged.
f Give your passenger all of the information in
this chapter.
Note
Airbag components (e.g. steering wheel, door lin-
ing, seats) may be disassembled only by an autho-
rized Porsche dealer.
When disposing of a used airbag unit, our safety
instructions must be followed. These instructions
can be obtained at any authorized Porsche dealer.
Function of the airbag systemAirbags are a supplemental safety system. Your
primary protection comes from your safety belts.
The front airbags are triggered during a frontal
collision of sufficient force and direction.
In the event of a side impact of corresponding
force, the side airbag on the impact side is
triggered.
The inflation process gene rates the amount of gas
required to fill the airbags at the necessary pres-
sure in fractions of a second.
Airbags help to protect the head and upper body,
while simultaneously damp ing the motion of the
driver and passenger in the impact direction in the
event of a frontal impact or side impact.
In order to help provide protection in severe colli-
sions which can cause death and serious injury,
airbags must inflate extremely rapidly. Such high
speed inflation has a negative but unavoidable
side effect, which is that it can and does cause in-
juries, including facial an d arm abrasions, bruising
and broken bones. You can help minimize such in-
juries by always wear ing your safety belts.
There are many types of accidents in which air-
bags are not expected to deploy. These include
accidents where the airbags would provide no be-
nefit, such as a rear impact against your vehicle.
Other accidents where the airbags are designed
not to deploy are those where the risk of injury
from the airbag deployment could exceed any pro-
tective benefits, such as in low speed accidents or higher speed accidents where the vehicle decele-
rates over a long time. Since airbag deployment
does not occur in all accidents, this further em-
phasizes the need for yo
u and your passenger to
always wear safety belts.
Your vehicle is equipped with a crash sensing and
diagnostic module. This module will record the
use of the seat belt restraint system by the driver
and passenger when the airbags and/or belt ten-
sioner work.
Advanced AirbagYour vehicle is equipped with a weight sensing sys-
tem for the passenger's seat in accordance with
U.S. Federal Motor Vehicle Safety Standard 208.
Depending on the weight acting on the passen-
ger's seat, the passenger's airbag will automati-
cally be switched on and off.
Depending on the angle and force of impact, the
passenger's airbag which is activated will be trig-
gered during a collision.
Precondition for switching the passenger's airbag
on and off, depending on weight:
– Vehicles equipped with key-operated airbag deactivation device:
Switch position AUTO.
– Ignition key is inserted.
Improper handling of the weight sensing
system can unintentional ly impair switching
the passenger's airbag off and on.

ABS Brake System
(Antilock Brake System)The ABS system represents a major contribution
to the enhancement of active safety in your vehi-
cle. This system prevents the wheels from locking
in a panic stop on almost all road surfaces.
With the ABS system in your vehicle, the
following areas are enhanced:
Steering, vehicle remains steerable under all
braking forces when ABS is engaged.
Good directional control , no swerving caused
by locking of wheels under braking conditions.
Shorter stopping distance , stopping distances
are usually reduced because controlled braking is
maximized.
Prevention of wheel lock up , no brake- induced
sliding and thus no localized tire wear from emer-
gency braking.
The crucial advantage of the ABS system over a
conventional brake system is in the area of main-
taining directional control and maneuverability of
the car in emergency situations.
Warning!
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 ABS.
The risk of accidents due to inappropriate
speed cannot be reduced, even by the ABS.
The driver bears the responsibility for all
driving maneuvers.
f Adapt your driving style to the prevailing road
and weather conditions.
f Obey all traffic laws.
Other vehicles not equipped with the ABS
system may not be able to maintain control,
especially on wet or poor road surfaces and
thus may be more likely to impact you from
behind.
f To minimize that risk, use your ABS system to
increase your ability to maneuver to avoid dan-
gerous situations and not merely to try to stop in the shortest distance possible.
Operation of the ABS systemA wheel speed sensor is mounted to each of the
four wheels. If wheel lock -up of either of the front
wheels or the rear wheels is sensed during brak-
ing, the brake pressure is adjusted automatically
until the wheel no longer slips.
If braking forces approach the wheel lock-up point
for all wheels (panic brak ing) the ABS system will
intervene to provide a rapid rythmic braking. The
proper operation of ABS is perceived by the driver
as a pulsating brake pedal in conjunction with au-
dible noise and perhaps some vibration.
f If you experience these sensations while driv-
ing or a road surface with questionable trac-
tion, reduce vehicle speed appropriate for the
prevailing road conditions.
f If full braking should be necessary, press the
brake pedal all the wa y down throughout the
entire braking procedure, regardless of the pul-
sating pedal. Do not ease up on pressure ap-
plied to the pedal.
The functional readiness of all the main electrical
components of the ABS is checked by an
electronic monitoring system both before and
while you drive.

Sport ModeA sportier car set-up is obtained when Sport mode
is switched on. Interventions by the Porsche
control systems are intentionally shifted towards
greater agility and driving performance:
– PASM (Porsche Active Suspension Manage-ment) is automatically changed to Sport mode,
resulting in a stiffer suspension setup.
– When Sport mode is active, the PDK transmis- sion switches to a sporty gear-changing map
and shortens the gear shifting times. Gear
changes take place faster, but fuel consump-
tion is also increased.
PSM (Porsche Stability Management) control
gives a sportier road-feel to the vehicle. PSM
interventions take place later than in Normal
mode. The driver can maneuver the vehicle
with greater agility at its performance limits,
without having to dispense with the assistance
of PSM in emergency situations. This helps to
achieve optimal lap times, particularly on race
circuits with a dry road surface.
– The electronic accelerator pedal reacts sooner, and the engine is more responsive to
throttle inputs. When Sport mode is switched
on, this function is ac tivated only after the
driver has floored the accelerator pedal or
released it briefly.
– The rpm limiter characteristic is “harder”, i.e. the engine is immediately throttled when the
performance limits are reached (only in manual selection mode for vehicles with PDK transmis-
sion).
f Please observe the chap ters on PSM, PASM
and PDK.
Switching Sport mode on and offSwitching Sport mode on and off simultaneously
activates and deactivate s the Sport mode in
PA S M .
If PASM Sport mode was activated with the PASM
button, PASM remains active.
After the ignition is switched off, Sport mode is
automatically reset to Normal mode.
SPORT button
f Press SPORT button A in the center console.
When Sport mode is switched on, the light-
emitting diode in the SPORT button is lit.
A sporty gear-changing map is enabled and the
gear shifting times ar e shortened for the PDK
transmission.
A sporty driving style is recognized more quickly
and the gear-changing speeds are adapted to
driving performance.
Deceleration downshifts are commenced earlier.
Downshifts are made during slight decelerations,
even at higher engine speeds.
f Please see the chapter “SPORT MODE
(“SPORT” AND “SPORT PLUS” MODES)” on
Page 180. SPORT PLUS button
(only on vehicles with PDK transmission)
In “Sport Plus” mode, the PDK transmission
changes to a shift program designed for driving
on race circuits. 7th gear is not selected.
The gear-changing performance is enhanced
significantly again compared with “Sport” mode.

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.

Rear Spoiler The rear spoiler improves driving stability, espe-
cially at higher speeds.
Warning!
Risk of accident, resulting in serious perso-
nal injury or death.
If the spoiler cannot be extended, driving sta-
bility will be adversel y affected by increased
rear axle lift, which could lead to loss of con-
trol.
f Adapt your driving style and speed to the
changed driving conditions.
f Have the fault remedied at an authorized
Porsche dealer.
Risk of injury during manual retraction or
extension of the spoiler with the vehicle
stationary.
f Make sure that no persons or objects are
within the range of movement of the rear
spoiler.
Risk of damage from pushing the vehicle by
the rear spoiler.
f Do not push the vehicle at the rear spoiler.
Automatic control
(automatic mode)The rear spoiler extends at approx. 75 mph
(120 km/h) and retracts again at approx. 50 mph
(80 km/h).
If the automatic control fails, the warning light
lights up.
The warning light in the on-board computer lights
up when the rear spoiler does not extend over
75 mph (120 km/h) or its end position is not
reached.
Manual control
(manual mode)When the ignition is on, the rear spoiler can be
extended and retracted manually using the button
in the center console.
Note
When the rear spoiler is extended manually, the au-
tomatic control does not operate and the rear
spoiler must be manually retracted.
