Driving and Driving Safety
Parking BrakeThe parking brake acts on the rear wheels and
serves to secure the car while parked.
fUse the parking brake only after the vehicle
has come to a full stop.
Applying the parking brakefPress down firmly on the foot pedal.
The warning light in the instrument panel lights
up.
A message will be displayed on the multi-
purpose display of the instrument panel if the
parking brake is not released before moving
off.
If the brake is not fully set, the vehicle may roll
without control.
fBefore exiting the vehicle, make sure that the
parking brake is fully applied and the vehicle is
not moving at all.
Danger!
Risk of serious personal injury or death. A
partially engaged parking brake may allow
the vehicle to roll, causing serious personal
injury or death to any person in its path.
fEngage the parking brake fully.
fPlease see the chapter “OVERVIEW OF
WARNING MESSAGES” on Page 149.fPress on the footbrake and pull handle A of the

Driving and Driving Safety Brake system warning light
You can check the functionality of the brake sys-
tem warning light by switching the ignition to the
“On” position and verifying that the warning light
illuminates.
The warning light in the instrument panel lights up.
A message will be displayed on the multi-purpose
display of the instrument panel if the brake fluid
level is too low, or (if the brake pedal travel has in-
creased) one of the two brake circuits has failed.
A greater braking pressure will be required, stop-
ping distances will be longer and the braking
behavior will change, particularly in curves.
With correctly adjusted brakes and a correctly
working brake system, the pedal travel to the
point of brake application should be 1-3/16 in. to
1-9/16 in. (30 to 40 mm). Whenever the brake
pedal travel exceeds this value, have the brake
system checked.
Brake pedal
Warning!
Risk of an accident, resulting in serious per-
sonal injury or death.
Any obstruction of the brake pedal could in-
crease the stopping distance.
fAlways check the movement of the brake pedal
before driving and make sure that it is not
obstructed by a floor mat or any other object.
fSecure 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
floor mats of the correct size including a securing possibility.
Note
In case one of the two brake circuits fails,
increased pedal travel is required to bring your
vehicle to a full stop.
Warning!
To avoid overheating and premature wear of
the brakes:
fBefore descending a steep grade, reduce
speed and shift the transmission into a lower
gear to control speed.
fDo not “ride the brakes” by resting your foot on
the pedal when not intending to apply brake
pressure.
fDo not hold the pedal down too long or too
often. This could cause the brakes to get hot and not function properly.

Brake boosterThe 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.
Moisture, road salt or grit on brakes affects
braking.
Brakes will dry after a few cautious brake applica-
tions.
Warning!
Risk of an accident, resulting in serious per-
sonal injury or death.
Driving through water may reduce the trac-
tion. Moisture on brakes from road water, car
wash, or a coating of road salt or grit may
affect braking efficiency.
fCautiously apply brakes to test brakes after exposure to road water, etc.
Brake wearYour 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 inter-
vals recommended in your Maintenance Book-
let.
Brake system warning light
You can check the functionality of the brake sys-
tem warning light by switching the ignition to the
“On” position and verifying that the warning light
illuminates.
A warning message will be displayed on the multi-
purpose display of the instrument panel if the
brake pads are worn, excessively.
fDo not continue to operate the vehicle.
Have your authorized Porsche dealer inspect
or replace the brake pads.
fPlease see the chapter “OVERVIEW OF
WARNING MESSAGES” on Page 149.
Brake pads and brake discsWear on the brake pads and brake discs depends
to a great extent on the driving style and the con-
ditions 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 tem-
peratures.
Certain speeds, braking forces and ambient
conditions (such as temperature and humidity)
therefore might cause the brakes to squeal.

The manual selection mode remains engaged:
– For passing
– Depending on lateral acceleration
– When the vehicle is stationary (e.g. at a
junction).
The system leaves manual selection mode:
– Automatically after around 8 seconds
(unless car is subject to high lateral accelera-
tion, is passing or stationary),
– if you depress the accelerator to kickdown.
Kickdown
The kickdown function is active in selector lever
position D.
fFor optimum acceleration, e.g. when overta-
king, depress the accelerator pedal beyond
the full-throttle point (kickdown).
The transmission shifts down depending on the
speed of travel and engine speed.
Upward shifts occur at the highest possible engine
speeds.
These gear-changing speeds remain active until
the accelerator is released to approx. 80% of the
full-throttle position.
Tip on driving
Unlike in the on-road driving program, an automa-
tic upshift is not performed in manual selection
mode M when the engine-speed limit is reached.
M - Manual selection mode (in the on-
road driving program)
Warning!
The kickdown function is not active in manual
selection mode “M”.
The kickdown function cannot be used to
downshift in manual selection mode “M”.
fTherefore shift down manually when accelera-ting (e.g. to overtake).Shifting up
fPress upper part (+) of a rocker switch A or
fPush selector lever B forward in the M gate.
Shifting down
fPress lower part (–) of a rocker switch A or
fPush selector lever B back in the M gate.
Depending on driving speed and engine speed,
you can shift up or down at any time. Gear
changes which would exceed the upper or lower
engine-speed limit are not executed by the control
unit.
You can change down two gears by quickly pres-
sing rocker switches A or selector lever B twice.
If PSM is active and the engine-speed limit is
reached, an automatic upward shift is performed
or, just before idling speed is reached, a down-
ward shift is performed.
fSelect an appropriately low gear on upward
and downward slopes.
This will ensure optimum use of engine power
and engine braking.
If manual mode fails, the control electronics
switch to automatic mode.
In this event, the instrument panel will display
selector lever position D.
fTo remedy the fault, please consult an
authorized Porsche dealer.

StoppingfFor a brief stop (e.g. at a traffic light), leave the
selector lever in drive position and hold the
vehicle with the brake pedal.
fDo not hold the car on a slope using the acce-
lerator. Use the brake pedal or the parking
brake instead.
fBefore leaving the vehicle, always apply the
handbrake and move the selector lever to
position P.
Tip on driving
In selector lever positions D and M, the hillholder
function makes it easier to move off from a stand-
still on an upward slope when the engine is run-
ning. The driver does not have to apply the brake.

ParkingfGo easy on the accelerator.
fWhen parking or maneuvring in a small space,
control the speed by careful use of the foot-
brake.Driving in winterIn wintry road conditions it is advisable to take
steep inclines in manual mode M. This prevents
the occurrence of gear changes that could cause
wheelspin.
Limp-home modeIf there is a fault in the transmission:
–An X appears instead of the current gear
indicator on the multi-purpose display of the
instrument panel.
The transmission no longer shifts.
fTo remedy the fault, immediately consult an
authorized Porsche dealer.
Warning!
Reverse gear lock monitoring is disabled in
the emergency running program.
Damage to the vehicle may result as well as
loss of control, if the vehicle is moving for-
ward fast enough to cause rear wheel lockup.
fDo not shift into R while the vehicle is moving forward.
Tip on driving
3rd or 5th gear in selector position D and reverse
gear R are now available and will allow you to
reach the nearest authorized Porsche dealer.
fPlease go to your authorized Porsche dealer
as soon as possible.
Selector lever emergency releaseIn the event of an electrical fault, the selector lever
lock in position P can be manually released (for
towing the vehicle, for example).
1. Fold up armrest.
2. Remove key B from the lower storage tray
(underneath the rubber mat) in the center
console.

emitting diodes next to the rocker switch (illustra-
tion).
The corresponding indicator lights on the instru-
ment panel and light-emitting diodes beside the ro-
cker switch flash several times during the shif-
ting process.Tip on driving center differential lock
When the center differential lock C is fully enga-
ged, there is no longer any speed difference bet-
ween the front and rear axles. If, for example, both
wheels at the front axle lose traction on an icy
road or soft surface, the rigidly linked drive wheels
will permit the car to continue moving neverthe-
less.
Tip on driving rear-differential lock
When the rear differential lock D is fully engaged,
there is no longer any speed difference between
the two rear wheels. If, for example, one drive
wheel at the rear axle loses traction on an icy road
or soft surface, the rigidly linked drive wheels will
permit the car to continue moving nevertheless.
Note on operation
The rear differential lock can be engaged only
while the engine is running.
