Seat Adjustment
Warning!
The seat may move unexpectedly if you
attempt to adjust while driving. This could
cause sudden loss of control or personal in-
jury.
fDo 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 safety belts or safety
belts worn by passengers in an excessively
reclined position can cause serious personal
injury in an accident.
fDo not operate the car with the driver or
passenger backrests excessively reclined
(see “Seat position”).
In the cabriolet, the windstop may be
damaged during seat adjustment and when
folding back the front-seat backrest.
fAdjust seat so that the seat backrest does not touch the windstop.
Seat position An 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 Tiptronic S:
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 and the steering-wheel
position so that your wrist 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 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.

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.

Controls, Instruments If the warning lights in the instrument panel and on-
board computer go on while driving, the brake flu-
id level may be too low, or (if the brake pedal travel
has increased) one of the two brake circuits may
have failed.
A greater braking pressure will be required, stop-
ping distances will be longer and the braking be-
havior will change, particularly in curves.
With correctly adjusted brakes, and a correctly
working brake system, the pedal travel to the
point of brake actuation should be 1-3/16 in. to
1-9/16 in. or 30 to 40 mm.
Whenever the brake pedal travel exceeds this dis-
tance, have the brake system checked.
Brake pedal
Warning!
Risk of an accident.
Any obstruction of the brake pedal could
increase the stopping distance.
fAlways check the movement of the brake pedal
before driving and make sure that it is not ob-
structed 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.
Note
In case one of the two brake circuits fails, in-
creased 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 or driving position 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.

Danger!
Engine exhaust fumes have many compo-
nents which you can smell. They also contain
carbon monoxide (CO), which is a colorless
and odorless gas.
Carbon monoxide can cause unconscious-
ness and even death if inhaled.
fNever start or let the engine run in an en-
closed, unventilated area.
It is not recommended to sit in your car for pro-
longed periods with the engine on and the car
not moving.
An unattended vehicle with a running engine
is potentially hazardous.
If warning lights should come on to indicate
improper operation, they would go unno-
ticed.
fNever leave the engine idling unattended.
Danger of fire.
fDo not park or operate the vehicle in areas
where the hot exhaust system may come in
contact with dry grass, brush, fuel spill or oth-
er flammable material.
