Rollover Protection System The Rollover Protection System on the Cabriolet
consists of two supplemental safety bars that to-
gether with the front windshield frame help to cre-
ate occupant survival space in case of rollover. Be-
cause of the extreme and unpredictable forces
which can be encountered in a rollover, it is not
possible to guarantee that occupants will be pro-
tected from all contact with exterior objects or the
ground. However, the Rollover Protection System
is designed to maintain the occupant survival
space.
The Rollover Protection System is activated auto-
matically in the event of an accident or extreme
driving situation.
The protective devices are located behind each
rear seat and rapidly deploy within a fraction of a
second.
They can deploy under:
– Extreme tilting of the vehicle.
– Loss of ground contact (e.g. Going over the
crest of a hill at high speed).
Danger!
Risk of death or serious injury.
fDo not block area of supplemental safety bars
with objects.
In the event of a deployment event, such
objects could potentially prevent such deploy-
ment from occuring, or such objects could
impact the car occupants at high speed.
fDo not tamper with or work on wiring and or
components of Rollover Protection System.
fAll work regarding this system must be carried
out by your authorized Porsche dealer.
fCheck functions and periodic service intervals
according to maintenance schedule (see your
authorized Porsche dealer).
To avoid damage to the convertible top:
fIf the supplemental safety bars are extended
for any reason, do not open or close converti-ble top. If a fault is present in the Rollover Protection Sys-
tem, a message appears in the on-board compu-
ter.
Extension of the supplemental safety bars is no
longer ensured.
fSee your authorized Porsche dealer immedi-
ately and have the fault remedied.
Lowering the supplemental safety bars
after deployment fHave this work performed by an authorized
Porsche dealer.

Parking Aids Parking assistantWhen the driver backs up, the parking assistant
system indicates the distance between the car
and a large obstacle behind it, by means of signal
tones.
Warning!
Risk of serious personal injury or death.
Parking assistant cannot detect small ob-
jects such as children and pets.
Despite use of the parking assistant system,
the driver is still responsible for taking due
care and assessing obstacles when backing
up.
fMake sure that no persons, especially small
children, animals or obstacles are within the maneuvring area.
The parking assistant system is activated auto-
matically when reverse gear is selected and the ig-
nition is on.
Note
Be aware that the parking assistant system is
not switched on if the car rolls backward without
reverse gear being engaged.
Ultrasound sensors
Sensors
Four ultrasound sensors in the rear bumper meas-
ure the distance to the closest obstacle.
– Range middle sensors around 60 in./150 cm
– Range outer sensors around 24 in./60 cm
Obstacles cannot be detected in the “blind” sen-
sor area (e.g. near the ground).
Note
The sensors must always be kept free of dust, ice
and snow in order to ensure that they are fully
functional.
Caution!
To avoid damaging the sensors:
fMaintain sufficient distance when cleaning with steam-jet units.

Retractable Rear SpoilerThe rear spoiler reduces rear axle lift, particularly
at high speeds.
Warning!
Risk of accident. If the rear spoiler cannot be
extended, driving stability will be adversely
affected by increased rear axle lift, which
could lead to loss of control.
fAdapt your driving style and speed to the
changed driving behaviour.
fHave the fault remedied at an authorized
Porsche dealer.
Risk of injury during manual retraction or
extension of the rear spoiler with the vehicle
stationary.
fMake 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 spoiler.
fDo not push the vehicle at the spoiler.
Automatic modeThe limits for automatic extension and retraction
of the spoiler depend on various circumstances
(e.g. driving speed, engine compartment temper-
ature).
Engine compartment temperature
under 122°F/55°C
Spoiler extends at 75 mph/120 km/h and
retracts at 37 mph/60 km/h.
Engine compartment temperature
over 140°F/60°C
Spoiler extends at 50 mph/80 km/h and retracts
at 19 mph/30 km/h.
If automatic control fails, a warning message is
displayed by the on-board computer.

Clutch Pedal The clutch pedal must be depressed fully
before the starter will engage.
Warning!
Risk of an accident.
fAlways 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.
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
nonskid floor mats of the correct size.
To avoid damage to the clutch and transmis-
sion:
fAlways depress the clutch pedal fully when
changing gears.
fDo 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 mean a malfunction of the
clutch.
fSee your Porsche dealer for correction.
Parking Brake Parking brake force is mechanically transferred to
the rear wheels by means of cables.
fUse the parking brake only after the vehicle
has come to a full stop.
Setting the parking brake fPull the lever all the way up (arrow).
With the ignition on, the parking brake warning
lights in the instrument panel and on-board
computer will come on if the lever is even
slightly raised. A firm pull upward is required to
properly engage the parking brake.
If the brake is not fully set, the vehicle may roll
without control.
fMove the selector lever to “P” (Tiptronic) or
move the gearshift lever to reverse or first
gear (Manual transmission).
fBefore exiting the vehicle, make sure that the
parking brake is fully set 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.Releasing the parking brakefPull the lever slightly up as you depress the re-
lease button, and then push the lever all the
way down.

The warning lights in the instrument panel and on-
board computer will go out after the parking brake
is fully released.
The warning lights are not an indicator that the
parking brake is fully set; 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, always set the parking
brake by pulling all the way up on the lever.
fMove the 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.
Brakes fMake 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 or
100 km/h, for example, it is not twice but four
times longer than 30 mph or 50 km/h. Tire trac-
tion 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 Compos-
ite 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 de-
pend on the amount of time the vehicle was
parked, whether granular or liquid road salt 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 function Your 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 and the other operates
the rear.
If one brake circuit has failed, the other will still op-
erate. 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.
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 cir-
cuit, 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 deal-er for repair.
