Driving with Launch Control
Driving with Launch Control allows you to achieve
maximum acceleration from a standing start. It is
intended to provide you with a unique enjoyment of
your vehicle under controlled circumstances and
is not intended to be used in any location where it
could be a nuisance to other persons.
Warning!
There is a risk of endangering other road
users if you use this Control in an improper
location or in a situation where other persons
might need to take evasive action due to the
rapid acceleration that this technology
permits.
fLaunch Control is designed to be used in a
controlled environment on closed circuit
driving courses where no vehicle cross traffic
or pedestrian traffic is present.
fUse Launch Control only if conditions permit it
to be applied in a safe manner. fDo not use Launch Control if there is a possibi-
lity it could endanger other persons. Such a
possibility exists if you cannot see that you
have a clear road with no possibility of cross
traffic in your intended direction of driving. Caution!
Stress on components increases dramatically
when starting with maximum acceleration in
comparison with normal driving off. Use of
Launch Control will inevitably reduce the life
of the engaged engine and transmission
components.
Preconditions:
– Launch Control should only be used when the
engine has reached operating temperature.
– “Sport Plus” mode must be switched on (light-
emitting diode in button is on and “SPORT
PLUS” is displayed on the on-board computer).
1. Press the brake with your left foot.
2. Quickly press down the accelerator fully
(kickdown activated) and hold.
The engine speed will flatten out at around
6500 rpm.
“Launch Control active” is displayed on the
on-board computer.3. Release the brake within a few seconds.
Remaining stationary for a long time with
“Launch Control active” can lead to overload-
ing of the transmission.
In order to protect the transmission, the engine
power is then reduced and the “Launch Control
active” process is cancelled.
Shifting gears on the steering wheel
With the shift buttons on the steering wheel, you
can change temporarily from automatic selection
mode D to manual mode M.
For example:
– Shifting down before bends and on entering
built-up areas.
– Shifting down on downward slopes
(engine braking).
– Shifting down for brief spurts of acceleration.
Manual selection mode remains engaged:
– for cornering (depending on the lateral acceler-
ation) and overrunning,
– when the vehicle is stationary (e.g. at a
junction).
The system leaves manual selection mode:
– automatically after approx. 8 seconds (unless
cornering or overrunning),
– after driving off.

Maintenance, Car Care
Brake Fluid LevelfPlease see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on Page 206.
fUse only new (unused) Original Porsche
brake fluid.
Warning!
Brake fluid is hazardous to your health, and
may be fatal if swallowed.
Brake fluid also attacks paintwork.
fKeep brake fluid out of children’s reach.
fTake care while topping off brake fluid not to
soil the luggage compartment or items of lug-gage.
Example: 911 Carrera, 911 Carrera SChecking the brake fluid levelThe reservoir for the hydraulic braking and clutch
systems is located in the luggage compartment.
1. Open and remove cover flap A.
2. Regularly check the brake-fluid level on the
transparent expansion tank through the
window B.
The fluid level should always lie between the
minimum and maximum marks.A slight decrease in the fluid level due to wear and
automatic readjustment of the disc brakes is
normal.
If, however, the fluid level falls markedly or below
the minimum mark, the braking system may have
developed a leak.
fHave the brake system checked without delay
at an authorized Porsche dealer.

Maintenance, Car Care

fAlways apply a fresh coating of suitable pre-
servative to unprotected areas after cleaning
the underside of the body, the transmission,
the engine or carrying out repairs to under-
body, engine or transmission components.
Effective rust-proofing is particularly important
during the cold weather season. If your car is driv-
en frequently in areas where salt has been spread
on the roads, the whole engine compartment
should be cleaned thoroughly after the winter to
prevent salt from causing any lasting damage. A
full under-body wash should also be performed at
the same time.Stainless steel exhaust tailpipesStainless steel exhaust tailpipes can discolor due
to soiling, strong heat, and combustion residues.
The original polish can be achieved again using
commercially available metal polishing paste or
metal polish.Light alloy wheels fPlease see the chapter “WASHING” on
Page 225.
Warning!
Danger of accident resulting in serious per-
sonal injury or death if cleaning agents (e.g.
wheel cleaning agents) come into contact
with the brake discs.The resulting film on the brake discs can im-
pair braking performance.
fMake sure that no cleaning agent comes into
contact with the brake discs.
fIf cleaning agent has come into contact with
the brake discs, thoroughly clean the brake
discs with a strong jet of water.
fPaying attention to any road users behind you,
dry the brake discs by applying the brakes at
short intervals.
Metal particles (such as brass or copper in brake
dust) must not remain too long on alloy wheels.
Contact corrosion can cause pitting.
Cleaners with an oxide-removing effect or the
wrong pH value, as are commonly used for other
metals, as well as mechanical tools and products,
will damage the oxide layer and are therefore
unsuitable.
fUse only cleaners for alloy wheels
(pH value 9.5). Products with the wrong
pH value can destroy the protective layer
on the wheels.
We recommend Porsche cleaner for alloy rims.
fIf possible, wash the wheels every two weeks
with a sponge or washing brush. If the wheels
are exposed to road salt, grit or industrial dust,
weekly cleaning is necessary.
Door, roof, lid and window seals
Caution!
The lubricant coating on the inner door
seals, convertible top and hardtop seals may
be damaged by unsuitable cleaning and care
agents.
fDo not use any chemical cleaning agents or
solvents.
fDo not use any preservative agents.
fWash dirt (e.g. abrasion, dust, road salt and
grit) from all seals regularly using warm soapy
water.
fIf there is a risk of frost, protect the outer door
seals and lid seals against freezing into place
with a suitable care product.Headlights, lights, interior and exterior
plastic parts, adhesive filmsUse only clean water and a little dishwashing
detergent to clean light lenses, plastic headlight
lenses, plastic parts and surfaces.
Do not clean when dry.
Use a soft sponge or a soft, lint-free cloth. Gently
wipe the surface without applying too much
pressure.
An interior window cleaner can also be used to
clean plastic surfaces (always read the cleaning
instructions on the container). We recommend
Porsche interior window cleaner.

Maintenance, Car Care fGently wipe the surface without applying too
much pressure.
fDo not clean when dry.
fNever use other chemical cleaners or
solvents.
fRinse cleaned surfaces with clear water.
Leather Characteristics and special features
The natural surface markings of leather, e.g.
creases, healed scars, insect sting marks, struc-
tural differences and slight variations in shade and
grain add to the attractiveness of the natural leath-
er product.
Observe the following care instructions:
Caution!
The leather will be damaged by the use of
unsuitable cleaning and care agents and by
incorrect treatment.
fDo not use caustic cleaners or hard cleaning
aids.
fPerforated leather must under no circumstances get wet on its reverse side.
fClean all types of leather regularly to remove
fine dust using a soft, damp, white woollen
cloth or a commercially available microfibre
cloth.fRemove heavy contamination with a leather
cleaner.
Always read the instructions for use given on
the containers.
We recommend Porsche leather cleaner.
Treat cleaned leather only with a leather care pro-
duct.
We recommend the Porsche leather care product.
Cleaning airbags covers
Danger!
There is a danger of serious personal injury
or death if the airbag system is impaired by
improper cleaning work.
fDo not make any modifications whatsoever on
individual components such as the padded
covers of the steering wheel, passenger side
instrument panel, the front seats and the door
linings.
fLet your authorized Porsche dealer clean these components.

ries includes mats of the correct size and with the
appropriate fastening.
Warning!
Risk of an accident resulting in serious per-
sonal injury or death.
fAlways check the movement of the pedals be-
fore driving and make sure that they are 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 - do not install them
loosely in the vehicle.
Your Porsche dealer will be glad to offer you nonskid floor-mats of the correct size.

should be free of dirt and salt deposits.
fFill up the fuel tank.
fChange the oil and oil filter, and run the engine
for several minutes.
fIncrease the tire pressure to 50 psi (3.5 bar).
It is not recommended to lift the vehicle, due to
the possibility of corrosion on shock absorber
piston shafts.
The vehicle should be moved slightly, approxi-
mately every four weeks, to prevent flat spot
on the tires. Climate control
The air conditioning system should be in good
working condition and fully charged.
Windshield/Headlight washer
fCheck and correct antifreeze/cleaning solution
level as necessary.
Electrical system
fRemove the battery from the vehicle and store
it in a cool dry place, not on a cement floor.
When the battery is disconnected, the
alarm system is deactivated.
fRecharge the battery every 3 months. If the
battery remains in the vehicle with the cables
connected, it is necessary to check, remove
and recharge the battery every 2-3 weeks.
Do not fast charge the battery.
fPlease see the chapter “BATTERY” on
Page 261.
Vehicle interior
The interior must be dry, especially in the area of
the floor carpets. The use of drying agents (Silica-
Gel) is recommended in vehicles with leather inte-
rior and in areas with high humidity. The recom-
mended amount is 3 fabric bags of 1.1 lbs.
(500 grams) each placed on the floor carpets.
Windows, doors and lids must be closed. The air
vents should be opened.

Practical Tips, Emergency Service and a half (1-1/2) times as well on the government
course as a tire graded 100.
The relative performance of tires depends upon
the actual conditions of their use, however, and
may depart significantly from the norm due to var-
iations in driving habits, service practices and dif-
ferences in road characteristics and climate.
Traction AA, A, B, C
The traction grades, from highest to lowest, are
AA, A, B, and C and they represent the tire’s ability
to stop on wet pavement as measured under con-
trolled conditions on specified government test
surfaces of asphalt and concrete.
A tire marked C may have poor traction perform-
ance.
Warning!
The traction grade assigned to this is based on
braking (straight-ahead) traction tests and does
not include cornering (turned) traction, accelera-
tion, hydroplaning or peak traction characteris-
tics.
Temperature A, B, C
The temperature grades are A (the highest), B and
C, representing the tire’s resistance to the gener-
ation of heat and its ability to dissipate heat when
tested under controlled conditions on a specified
indoor laboratory test wheel.
Sustained high temperatures can cause the mate-
rial of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden tire failure.
The grade C corresponds to a level of perform-
ance which all passenger car tires must meet un-
der the Federal Motor Vehicle Safety Standard No.
109.
Grades B and A represent higher levels of per-
formance on the laboratory test wheel than the
minimum required by law.
Warning!
The temperature grade for this tire is established
for a tire that is properly inflated and not overload-
ed.
Excessive speed, underinflation, or excessive
loading, either separately or in combination, can
cause heat buildup and possible tire failure, result-
ing in serious personal injury or death. Tire pressures
Warning!
Incorrect tire pressure causes increased tire
wear and adversely affects road handling.
This could lead to tire failure, resulting in loss
of control, leading to serious personal injury
or death.
fAlways use an accurate tire pressure gage
when checking inflation pressures.
fDo not exceed the maximum tire pressure list-
ed on the tire sidewall.
Please see the chapter “TIRE PRESSURE PLA-
TE” on Page 285.fCold tire inflation pressure means: all tires
must be cold, ambient temperature maximum
(68 °F/20 °C)
, when adjusting the inflation
pressure.
Avoid sunlight striking the tires before measur-
ing cold pressures, since the pressures would
rise from temperature influence.
fValve caps protect the valve from dust and dirt,
and thus from leakage.
Always screw caps tightly down.
Replace missing caps immediately.
fUse only plastic valve caps.
fDo not use commercially available sealant or
tire inflating bottles. Only use Porsche
approved tire sealant.
fPlease see the chapter “TIRE PRESSURES FOR
COLD TIRES (68 °F / 20 °C)” on Page 289.
