California Proposition 65 Warning
Warning!
Engine exhaust, some of its constituents, and
certain vehicle components contain or emit chemi-
cals known to the State of California to cause
cancer and birth defects or other reproductive
harm.
In addition, certain fluids contained in vehicles and
certain products of component wear contain or
emit chemicals known to the State of California to
cause cancer and birth defects or other reproduc-
tive harm.Hot Exhaust Pipes
Warning!
Risk of burn injury when standing near or
coming into contact with the exhaust pipe.
The exhaust pipe is hot when the vehicle is running
and remains hot for some time after the vehicle is
turned off.
fTo prevent injury, make a point of noting where
your vehicle’s exhaust pipe is, avoid placing
your legs near the exhaust pipe when loading
and unloading cargo in the rear, and closely
supervise children around the vehicle during
time when the exhaust pipe could be hot. A hot exhaust pipe can cause serious burns.
Portable Fuel Containers
Danger!
Portable fuel containers may leak, whether
they are full or partially empty. Fuel leaking
from a portable container carried in your
vehicle could, in case of an accident, cause
a fire or explosion, resulting in serious
personal injury or death.
fNever carry additional fuel in portable contai-ners in your vehicle.
Vehicles with SportDesign package
Caution!
Risk of damage. On vehicles with Sport-
Design package, front, rear, and side
member trim are painted and located lower
on the vehicle. Off-road driving can seriously
damage these trim parts.
fWhen driving off-road, make sure these parts
are not damaged.
fMake sure there is sufficient clearance
between obstacles and the underside of the
vehicle.
fAvoid driving through water.
fDo not use side member trim as a running board.
Porsche Ceramic Composite Brake
(PCCB)fPlease see the chapter “BRAKES” on
Page 163.
The high-performance brake system is designed
for optimal braking effect at all speeds and tempe-
ratures.
Certain speeds, braking forces and ambient condi-
tions (such as temperature and humidity) therefore
might cause brake noises.
Wear on the different components and braking
system, such as brake pads and brake discs,
depends to a great extent on the individual driving
style and the conditions of use and therefore
cannot be expressed in actual miles on the road.
The values communicated by Porsche are based
on normal operation adapted to traffic. Wear incre-
ases considerably when the vehicle is driven on
race tracks or through an aggressive driving style.
fPlease consult an authorized Porsche dealer
about the current guidelines in effect before
such use of your vehicle.

The warning lights will go out after the parking
brake is fully released.
The warning lights are not an indicator that the
parking brake is fully applied; it is only intended to
be a warning to release the parking brake before
driving the car.
Caution!
A partially engaged brake will overheat the
rear brakes, reduce their effectiveness and
cause excessive wear.
fRelease the parking brake fully.
fWhen parking your car, press down firmly on
the foot pedal.
fMove the Tiptronic selector lever to “P”
(Tiptronic) or move the gearshift lever to
reverse or first gear (Manual transmission).
fOn hills also turn the front wheels towards the
curb.
BrakesfMake it a habit to check the operation of your
brakes before driving.
Keep in mind that the braking distance increases
very rapidly as the speed increases. At 60 mph
(100 km/h), for example, it is not twice but four
times longer than 30 mph (50 km/h). Tire traction
is also less effective when the roads are wet or
slippery.
fTherefore, always maintain a safe distance
from the car in front of you.Vehicles without Porsche Ceramic
Composite Brake (PCCB)Even though the brake discs consist of alloyed
grey cast iron, they will unavoidably start to cor-
rode if your car is parked for an extended period.
The brakes will tend to “rub” as a result.
The nature, extent and effects of corrosion
depend on the amount of time the vehicle was
parked, whether road salt or grit was spread and
whether grease-dissolving agents were used in
car washes.
If the braking comfort is noticeably impaired, we
recommend having the brake system checked by
experts at an authorized Porsche dealer.
Brake system functionYour Porsche is equipped with a power assisted
hydraulic dual circuit brake system with disc
brakes at the front and rear.
Both circuits function independently. One brake
circuit operates the front left and rear right wheel
and the other operates the front right and rear left
wheel.
If one brake circuit has failed, the other will still
operate. However, you will notice an increased
pedal travel when you apply the brakes.Failure of
one brake circuit will cause the stopping distance
to increase.
Warning!
Risk of an accident, resulting in serious per-
sonal injury or death.
In the unlikely event of hydraulic failure of
one brake circuit:
fPush the brake pedal down firmly and hold it in
that position. A mechanical linkage activates
the second circuit, and you will be able to bring
the vehicle to a stop.
fAfter bringing your vehicle to a complete stop,
avoid driving the vehicle and instead have it
towed to the nearest authorized Porsche dealer for repair.

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.

Driving and Driving Safety New brake pads or linings
New brake pads have to be “broken in”, and there-
fore only attain optimal friction when the car has
covered several hundred miles or km.
The slightly reduced braking ability must be com-
pensated for by pressing the brake pedal harder.
This also applies whenever the brake pads and
brake discs are replaced.
Warning!
fDo not obstruct the pedal travel with floor mats
or other objects.
The brake booster is ready for operation only
while the engine is running.
If the engine is switched off or there is a defect in
the brake booster, much greater force has to be
applied to the pedal when braking.
fPlease see the chapter “TOWING” on
Page 342.
In heavy rain, while driving through water or after
leaving a car wash, the braking action may be
delayed and increased pressure may be required.
fFor this reason, keep further back from the ve-
hicle in front and “dry” the brakes by applying
them at intervals. Make sure that following traf-
fic is not affected.
After a long drive over salted or sanded roads, a
coating may form on the brake discs and pads
that significantly reduces friction and thus braking
action.fEven though the brake discs consist of alloyed
grey cast iron, they will unavoidably start to
corrode if your car is parked for an extended
period. The brakes will tend to “rub” as a
result.
The nature, extent and effects of corrosion
depend on the amount of time the vehicle was
parked, whether road salt or grit was spread
and whether grease-dissolving agents were
used in car washes (not on vehicles with
Porsche Ceramic Composite Brake).
To prevent corrosion of the brake discs, “brake
them dry” before parking the car (not on
vehicles with Porsche Ceramic Composite
Brake).
If the braking comfort is noticeably impaired,
we recommend having the brake system
checked by experts at an authorized Porsche
dealer.
fTo relieve the braking system on downhill
stretches, change down to a lower gear in
enough time to obtain engine braking.
If engine braking is insufficient on steep
stretches, operate the footbrake at intervals.
Continuous braking overheats the brakes and
reduces the braking effect.
fPlease see the chapter “BRAKE-FLUID LEVEL”
on Page 257.

Selector lever positionIndicator for selector lever position and
engaged gearWhen the engine is running, the selector lever
position and engaged gear are indicated.
Selector Lever PositionsP – Parking lockIn selector lever position P, the driven wheels are
mechanically locked.
fEngage parking lock only when vehicle is
stationary.
fEngage parking lock after applying the
parking brake and release it before releasing
the parking brake.
fAlways apply the parking brake before leaving
the vehicle.
The ignition key can be withdrawn only in selector
lever position P.R – ReversefSelect reverse only if car is stationary and the
brake is applied.N – NeutralSelector lever position N must be selected for
towing or in car washes, for example.
fSelect the desired position for moving off
(D, M or R) only when the engine is idling and
when depressing the brake pedal.
D - Automatic selection mode (in the road
driving program)fUse selector lever position D for “normal”
driving.
The gears are shifted automatically according
to the accelerator position and speed.
Depending on the way the vehicle is driven and on
the resistance (e.g. uphill), the gear-changing
points are shifted towards higher or lower engine-
speed ranges. Movement of the accelerator,
driving speed, longitudinal and lateral acceleration
and the road profile all have an influence on the
gear-changing characteristic.
When PSM is switched off, transmission gear
changes are done at higher engine speeds.
Unwanted upward shifts, e.g. before corners, are
prevented by swiftly releasing the accelerator
pedal.
Depending on lateral acceleration, upward
changes on corners are not made until the engine-
speed limit is reached.
During braking, and depending on the amount of
deceleration, the Tiptronic changes down earlier.
For subsequent cornering, the right gear is
engaged when pressure is applied to the brakes
before the corner.

Porsche Stability Management (PSM)PSM is an active control system for stabilization of
the vehicle during extreme driving maneuvers. It
operates together with the Porsche Traction
Management (PTM) system.
PSM makes use of both the ABD and TCS
systems, as well as the known functions of the
anti-lock brake system (ABS) and engine drag
torque control system (MSR).
Warning!
In spite of the advantages of PSM, it is still the
driver’s responsibility to adapt her/his driving style
and maneuvers in line with road and weather
conditions, as well as the traffic situation.
The increased safety that is provided should not
induce you to take greater risks with your safety.
The limits set by the physics of driving cannot be
overcome, even with PSM.
Risks of accident due to inappropriate speed
cannot be reduced by PSM.Advantages of PSM
– Best possible traction and lane-holding ability
in all driving situations – even on road surfaces
with varying friction.
– The system compensates for undesired vehi-
cle reactions (load-alteration effect) when the
driver releases the accelerator pedal or brakes
on bends. 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 corners and on
different or varying road surfaces.
– Improved brake functioning and reduced
stopping distance in the event of emergency
braking.Readiness for operation
PSM is switched on automatically every time you
start the engine.
Function
Sensors at the wheels, brakes, steering system
and engine continuously measure:
– Driving speed
– Direction of travel (steering angle)
– Lateral acceleration
– Longitudinal acceleration
– Rate of turn about the vertical axis
PSM uses these values to determine the direction
of travel desired by the driver.
PSM intervenes and corrects the course if the
actual direction of motion deviates from the
desired course (steering-wheel position):
It brakes individual wheels as needed. If neces-
sary, PSM additionally influences the engine power
or the gear-changing characteristic of the
Tiptronic in order to stabilize the vehicle.
