Shifting Gears
Porsche Doppelkupplung (PDK)The Porsche Doppelkupplung (PDK) is a seven-
speed transmission with an “automatic” and a
“manual” selection mode.
In automatic selection mode (selector lever
position D), gear changing is automatic.
You can change temporarily from automatic to
manual mode using the shift buttons on the
steering wheel.
In manual selection mode (selector lever
position M), you change gear using the shift
buttons on the steering wheel or with the PDK
selector lever.
You can change between se lector lever position D
and M as you wish while driving.
Note
f Take care not to operat e the shift buttons on
the steering wheel in advertently in either
automatic or manual mode, thereby triggering
undesired gear changes.
Changing the selector lever positionThe selector lever is locked when the ignition is
switched off.
When the ignition is switched on, the selector lever
can be moved from position P and N only when
the release button is pressed, and when the brake
pedal is pressed.
Release button
The release button ( arrow) in the selector lever
prevents the gear from being changed unintention-
ally.
The release button must be pressed when shifting
to position R or P.
StartingThe engine can be started only if the brake
pedal is depressed and the selector lever is in
position P or N.Driving offf Only select the desired position for driving off
( D, M or R ) when the engine is idling and the
brake pedal is depressed.
f Since the vehicle creeps when in gear, do not
release the brake until you want to move off.
f After selecting a gear, do not accelerate until
you can feel that the gear is engaged.
Driving off on hills
The Drive-Off Assistant assists the driver when
moving off on hills. The vehicle is held on the slope
for a short time during the change from the brake
pedal to the accelerator in order to allow driving
off directly after the brake is released.
f Please see the chapter “DRIVE-OFF ASSIS-
TANT” on Page 177.

Shifting Gears
Selector lever positionsP – Parking lockfEngage parking lock only when vehicle is
stationary.
If selector-lever position P is flashing in the
instrument cluster, the parking brake is not
engaged. The vehicle can roll away.
Engage selector-lever position P again by
moving the selector lever out of R.
f Engage parking lock after applying the
handbrake and release it before releasing the
handbrake.
The ignition key can be withdrawn only in
selector lever position P.R – Reverse gearf Select 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.
f Only select the desired position for driving off
(D, M or R) when the engine is idling and the
brake pedal is depressed.
D - Automatic selection modeSelect position D for “normal” driving. The gears
are shifted automatically according to the acceler-
ator position and speed.
Depending on the way the vehicle is driven
(economical, comfortable or sporty driving style)
and on the resistance (e.g. uphill), the gear-
changing points are shifted towards higher or
lower engine-speed ranges.
The accelerator position, driving speed, engine
speed, longitudinal and lateral acceleration and
the road profile all have an influence on the gear-
changing characteristic.
Unwanted upward shifts, e.g. before bends, are
prevented by swiftly releasing the accelerator
pedal.
Depending on lateral acceleration, upward
changes on bends are not made until the engine-
speed limit is reached.
Under braking, and depending on the amount of
deceleration, the PDK transmission changes down
earlier.
For subsequent cornering, the right gear is
engaged when pressure is applied to the brakes
before the bend. The bend is taken in the right
gear, and when you accelera te out of the bend you
do not have to change down. With a sporty driving style, downshifts are already
initiated when the brake pedal is touched lightly.
This further enhances
a dynamic driving style.
The PDK transmission temporarily changes to the
sportiest gear-changing map, i.e. to the highest
possible gear-changing poin ts, if the accelerator
pedal is pressed quickly. The transmission accord-
ingly shifts down immediately by one or two gears
(temporary change-down).
The transmission no longer selects 7th gear at
high driving speeds.
Sport mode
(“Sport” and “Sport Plus” modes)
“Sport” mode activated:
The PDK transmission switches to a sporty gear-
changing map and shortens the gear shifting
times.
A sporty driving style is recognised more quickly
and the gear-changing speeds are adapted to
driving performance.
Deceleration downshifts are commenced earlier.
Downshifts are already carried out in the case of
slight decelerations, even at higher engine
speeds.

Maintenance, Car Care
Exercise Extreme Caution when
Working on your Vehicle
Danger!
Ignoring the following instructions may
cause serious personal injury or death.
f The engine compartment of any motor vehicle
is a potentially hazardou s area. If you are not
fully familiar with proper repair procedures, do
not attempt the adjustments described on the
following pages.
This caution also applies to the entire vehicle.
f O n l y w o r k o n y o u r v e h i c l e o u t d o o r s o r i n a w e l l
ventilated area.
f Ensure that there are no open flames in the
area of your vehicle at any time when fuel
fumes might be present. Be especially cau-
tious of such devices such as hot water heat-
ers which ignite a flame intermittently.
f Before working on any part in the engine com-
partment, turn the engine off and let it cool
down sufficiently. Hot engine compartment
components can burn skin on contact.
f Be alert and cautious around engine at all
times while the engine is running.
If work has to be performed with the engine
running, always set the parking brake, and
make sure the shift lever is in neutral position
or the PDK selector lever in position P or N . f
In particular, be very careful to ensure that
items of clothing (ties, shirt, sleeves etc.),
jewelry, long hair, hand or fingers cannot get
caught in the engine-compartment blower, fan,
belts or other moving parts.
The radiator and radiator fans are in the front
of the car.
The engine-compartment blower is mounted in
the engine-compartment.
The fans can start or continue running as a
function of temperature, even with the engine
switched off.
Carry out work in these areas only with the en-
gine off, the ignition switched off, and exercise
extreme caution.
f Your Porsche is equipped with an electronic ig-
nition system. When the ignition is on, high
voltage is present in all wires connected with
the ignition system; therefore, exercise ex-
treme caution when working on any part of the
engine while the ignition is on or the engine is
running.
f Always support your car with safety stands if it
is necessary to work under the car.
f When working under the car without safety
stands but with the wheels on the ground,
make sure the car is on level ground, the
wheels are blocked, and that the engine
cannot be started.
Remove the ignition key. f
Do not smoke or allow an open flame around
the battery or fuel.
Keep a fire extinguisher in close reach.
f Incomplete or improper servicing may cause
problems in the operation of the car. If in doubt
about any servicing, have it done by your
authorized Porsche dealer.
Improper maintenance during the warranty
period may affect your Porsche warranty cov-
erage.
f Supplies of fluids, e.g. engine oil, brake fluid or
coolant, are hazardous to your health.
Keep these fluids out of children’s reach and
dispose of them in accordance with the appro-
priate regulations.
f Some countries require additional tools and
special spare parts to be carried in your vehi-
cle.
Please make enquiries before driving abroad.

health.
f Fire, open flame and smoking are prohibited
when handling fuel.
f Avoid contact with skin or clothing.
f Do not inhale fuel vapors.
To prevent damage to the emission control
system and engine:
f Never drive the tank completely out of fuel.
f Avoid high cornering speeds after the warning lights have come on.
f Please see the chapter “FUEL ECONOMY” on
Page 194.
Please see the chapter “EMISSION CONTROL
SYSTEM” on Page 198.

Unleaded fuels may not be available outside the
continental U.S. and Canada. Therefore, we rec-
ommend you do not take your car to areas or
countries where unleaded fuel may not be availa-
ble. Octane ratings Octane rating indicates a fuel’s ability to resist det-
onation. Therefore, buying the correct octane gas
is important to prevent engine “damage”.
The RON octane rating is based on the research
method. The CLC (U.S. Cost of Living Council oc-
tane rating) or AKI ( anti knock index) octane rating
usually displayed on U.S. fuel pumps is calculated
as research octane numb er plus motor octane
number, divided by 2, that is written as:
The CLC or AKI octane rating is usually lower than
the RON rating:
For example: 95 RON equals 90 CLC or AKI
Fuels containing ethanolDo not use any fuels containing more than 10 per-
cent ethanol by volume.
We recommend, however, to change to a different
fuel or station if any of the following problems oc-
cur with your vehicle:
– Deterioration of driveability and performance.
– Substantially reduced fuel economy.
– Vapor lock and non-start problems, especially at high altitude or at high temperature.
– Engine malfunction or stalling. Portable Fuel Containers
Danger!
Portable fuel containers, full or partially
empty, may leak causing an explosion, or re-
sult in fire in case of an accident.
f Never carry additional fuel in portable contain-ers in your vehicle.
Fuel Evaporation Control Fuel tank venting The evaporation chamber and the carbon canister
prevent fuel from escaping to the atmosphere at
extreme high outside temperatures, when driving
abruptly around curves and when the car is parked
at an incline or in any other nonlevel position. Vapor control system and storage When the fuel tank is filled, vapors are collected in
the evaporation chamber by a vent line leading the
vapors to the carbon canister where they are
stored as long as the engine does not run. Purge system When the engine is running, the fuel vapors from
the canister will be mixed with fresh air from the
ambient air of the canister. This mixture will be
directed to the intake air housing by the tank vent
line, mixed with the intake air and burned during
normal combustion.

Power Steering
Warning!
Risk of accident resulti ng in serious personal
injury or death.
When the engine is stopped (e.g. when being
towed) or the hydraulic system fails, there is
no assistance for steering.
Therefore, substantially more force will have
to be exerted in order to steer.
f Exercise great care when being towed.
f Have the fault remedied at your nearest autho-rized Porsche dealer.
Note
The flow noise heard at full steering lock is system
related and does not indi cate a defect in the
steering system.
Checking hydraulic fluid f Please see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on Page 186.
The hydraulic fluid reservoir is located in the engi-
ne compartment.
Regular checking of hydraulic fluid is part of
servicing.
Air Filter A dirty air filter not only reduces engine perform-
ance, but can lead to premature engine wear.
Regular filter replacement is part of the routine
maintenance service.
f In dusty conditions, check the filter element
more frequently and replace if necessary.Combination Filter The fresh air passing through the combination fil-
ter into the passenger co mpartment is virtually
free of dust, pollen, and unpleasant odors.
f If the outside air is polluted by exhaust fumes,
press the circulating-air button.
A dirty filter can be the cause of reduced air flow:
f Have filter replaced by your authorized
Porsche dealer.
Regular filter replacement is part of the routine
maintenance service.
Fluids/Oils for Manual
Transmission and Porsche
Doppelkupplung (PDK)The transmission fluids/oils have to be checked
and changed at the intervals listed in your Mainte-
nance Schedule.
f Please see the chapter “CAPACITIES” on
Page 271.
Do not tow the car or run the engine without fluid/
oil in the transmission. The transmission may be
damaged by even a tiny speck of dirt, only a clean
funnel or spout must be used when adding fluid/
oil.
We recommend that you have the fluids/oils
changed at your Porsche dealer, who has the re-
quired lubricants and the necessary filling equip-
ment.
f If you suspect an oil leak in the transmission,
have your authorized Porsche dealer check it
out immediately.

Door lock fTo prevent the door lock from freezing during
the cold season, the lo ck cylinder should be
covered during a wash.
f Should the lock freeze, use an ordinary de-icer.
In many cases, a well warmed key can help.
Never use excessive force.Paint To protect the paint on yo ur vehicle in the best
possible way against mechanical and chemical
damage, you should
– preserve it regularly,
– polish it if necessary,
– remove spots and stains, and
– repair damaged paintwork.
f Do not apply care products containing silicone
to the convertible top and windows.
General information
f Never rub a dusty vehicle with a dry cloth,
because the grains of dirt will damage the
paintwork.
f Do not treat matt-painted components with
preservatives or polish es, otherwise the matt
effect will be lost. Preservation
The paint surface becomes dull over time due
to weathering.
f
Preserve paint regularly.
f Apply paint preservative after washing the
vehicle and polish it smooth to preserve the
paintwork.
This keeps the paint shiny and elastic. Dirt is
prevented from adhering to the paint surface and
industrial dust is prevented from penetrating
the paint.
Polishing
Do not resort to using Porsche polish until it be-
comes evident that the no rmal preservatives no
longer produce the desired finish.
Spots and stains
f Remove tar stains, grease, oil spots and dead
insects as soon as possible with Insect Remov-
er. They can cause discoloration if allowed to
remain on the paintwork.
f Wash the affected area immediately after treat-
ing it. Minor paint damage
f
Have minor paint damage, such as scratches,
scores or chips caused by flying stones, re-
paired immediately by your authorized
Porsche dealer before corrosion sets in.
However, if there are already traces of corrosion,
they must first be removed carefully and thorough-
ly. Coat the area with a rust-proofing primer and
finish off with a top coat. The paint code and color
number are found on the data bank in the Mainte-
nance booklet.
f Please see the chapter “VEHICLE DATA BANK”
on Page 264.
Engine compartment The engine compartment and the surface of the
engine are treated with a corrosion-inhibitor at the
factory.
If degreasing solvents are used to clean the en-
gine compartment or the engine is washed down,
the process almost invariably removes the corro-
sion-inhibiting coating. It is then absolutely neces-
sary to have a durable preservative applied to all
surfaces, body seams, joints and assemblies in
the engine compartment. This also applies when
corrosion-inhibitor parts are replaced.
