Shifting Gear Shifting gear on the steering wheel
With the toggle switches on the steering wheel,
you can change temporarily from automatic
selection mode D to manual mode M.
Advantages:
– Shifting down before bends and on entering bu-
ilt-up areas.
– Shifting down on downward slopes (engine bra-
king).
– Shifting down for brief spurts of acceleration.
– Selecting 1st gear for moving off.
The manual selection mode remains engaged:
– for cornering (depending on the lateral
acceleration) 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),
– if you depress the accelerator to kickdown,
– after moving off. Temporary change-down
Conditions:
Speed is higher than approx. 33 mph (54 km/h).
fDepress accelerator quickly.
The Tiptronic changes temporarily to the spor-
tiest gear-changing map, i.e. to the highest
possible gear-changing points. Correspondin-
gly, the transmission shifts down immediately
by one or two gears.
Ending the function:
fRelease the accelerator markedly. Kickdown
The kickdown function is active in selector lever
position D, even if you temporarily change to ma-
nual mode M using the toggle switches on the
steering wheel.
fFor optimum acceleration, e.g. when overta-
king, depress the accelerator pedal beyond
the full-throttle point (kickdown).
The transmission shifts down depending on the
speed of travel and engine speed.
Upward shifts occur at the highest possible engine
speeds.
These gear-changing speeds remain active until
the accelerator is released to approx. 80% of the
wide open throttle position.

WindstopfMake sure that all windstop parts are fastened
securely, especially when driving with the
convertible top open.
Note
When the convertible top is closed, it is a good
idea to remove the center section of the windstop
to permit good ventilation of the interior or for
demisting the rear window.
This is particularly the case in cold, wet weather.
Removing outer windstop partsfPress windstop parts to the rear and up out of
the roll-over bar and take it out.Installing outer windstop partsfFirst insert the windstop parts in the roll-over
bar from the rear, then push it up into the bar.

Maintenance, Car Care
Exercise Extreme Caution when
Working on your Vehicle
Danger!
Ignoring the following instructions may cau-
se serious personal injury or death.
fThe engine compartment of any motor vehicle
is a potentially hazardous area. If you are not
fully familiar with proper repair procedures, do
not attempt the adjustments described on the
following pages.
This caution applies to the entire vehicle.
fO 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.
fEnsure that there are no open flames in the
area of your vehicle at any time when fuel fu-
mes might be present. Be especially cautious
of such devices such as hot water heaters
which ignite a flame intermittently.
fBefore 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.
fBe alert and cautious around engine at all ti-
mes 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 or the se-
lector lever is in position P or N. fIn particular, be very careful to ensure that
items of clothing (ties, shirt, sleeves etc.), je-
welry, 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 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 and exercise extreme caution.
fYour Porsche is equipped with an electronic ig-
nition system. When the ignition is on, high vol-
tage is present in all wires connected with the
ignition system; therefore, exercise extreme
caution when working on any part of the engine
while the ignition is on or the engine is running.
fAlways place the vehicle on stable supports if
work has to be carried out under the vehicle.
Jacks are not suitable for this kind of work.
fWhen 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 can-
not be started.
Remove the ignition key. fDo not smoke or allow an open flame around
the battery or fuel.
Keep a fire extinguisher in close reach.
fIncomplete or improper servicing may cause
problems in the operation of the car. If in doubt
about any servicing, have it done by your au-
thorized Porsche dealer.
Improper maintenance during the warranty pe-
riod may affect your Porsche warranty cove-
rage.
fSupplies 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.
fSome countries require additional tools and
special spare parts to be carried.
Please make enquiries before driving abroad.
Power measurements Power measurements on dynamometers are not
approved by Porsche.

Operating Your Porsche in other
Countries Government regulations in the United States and
Canada require that automobiles meet specific
emission regulations and safety standards. There-
fore, cars built for the U.S. and Canada differ from
vehicles sold in other countries.
If you plan to take your Porsche outside the conti-
nental limits of the United States or Canada, there
is the possibility that
– unleaded fuel may not be available;
– unleaded fuel may have a considerably lower
octane rating. Excessive engine knock and se-
rious damage to both engine and catalytic con-
verters could result;
– service may be inadequate due to lack of pro-
per service facilities, tools or diagnostic equip-
ment;
– replacement parts may not be available or very
difficult to get.
Porsche cannot be responsible for the me-
chanical damage that could result because
of inadequate fuel, service or parts availabi-
lity.
If you purchased your Porsche abroad and want to
bring it back home, be sure to find out about ship-
ping and forwarding requirements, as well as cur-
rent import and customs regulations.

Maintenance, Car Care
Fuel Recommendations Your Porsche is equipped with catalytic conver-
ters and must use UNLEADED FUEL ONLY.
Your engine is designed to provide optimum per-
formance and fuel economy using unleaded premi-
um fuel with an octane rating of 98 RON
(93
CLC or AKI). Porsche therefore recom-
mends the use of these fuels in your vehicle.
Porsche also recognizes that these fuels may not
always be available. Be assured that your vehicle
will operate properly on unleaded premium fuels
with octane numbers of at least 95
RON
(90 CLC or AKI), since the engine’s ”Electronic
Oktane™ knock control“ will adapt the ignition ti-
ming, if necessary.
T h e u s e o f U N L E A D E D F U E L O N LY i s c r i t i c a l l y
important to the life of the catalytic conver-
ters. Deposits from leaded fuels will ruin the
converters and make it ineffective as an
emission control device.
Cars with catalytic converters have a smaller fuel
tank opening, and gas station pumps have smaller
nozzles. This will prevent accidental pumping of
leaded fuel into cars with catalytic converters. Unleaded fuels may not be available outside the
continental U.S. and Canada. Therefore, we re-
commend you do not take your car to areas or
countries where unleaded fuel may not be availab-
le.
Octane ratings Octane rating indicates a fuel’s ability to resist de-
tonation. 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 (antiknock index) octane rating
usually displayed on U.S. fuel pumps is calculated
as research octane number 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 alcohol and ether Some areas of the U.S. require oxygenated fuels
during certain portions of the year. Oxygenated fu-
els are fuels which contain alcohols (such as me-
thanol or ethanol) or ether (such as MTBE).
Under normal conditions, the amount of these
compounds in the fuel will not affect driveability.
You may use oxygenated fuels in your Porsche,
provided the octane requirements for your vehicle
are met. We recommend, however, to change to a
different fuel or station if any of the following pro-
blems occur 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. RON MON+

Maintenance, Car Care
Emission Control System In the interest of clean air Pollution of our environment has become a pro-
blem that is of increasing concern to all of us. We
urge you to join us in our efforts for cleaner air in
controlling the pollutants emitted from the auto-
mobile.
Porsche has developed an emission control sys-
tem that controls or reduces those parts of the
emission that can be harmful to our environment.
Your Porsche is equipped with such a system.
Porsche warrants the Emission Control System in
your new car under the terms and conditions set
forth in the Warranty Booklet.
You, as the owner of the vehicle, have the
responsibility to provide regular maintenance ser-
vice for the vehicle and to keep a record of all
maintenance work performed. To facilitate record
keeping, have the service performed by authori-
zed Porsche dealers. They have Porsche trained
technicians and special tools to provide fast and
efficient service.
To assure efficient operation of the
Emission Control System fHave your vehicle maintained properly and in
accordance with the recommendations descri-
bed in your Maintenance Booklet.
Lack of proper maintenance, as well as impro-
per use of the vehicle, will impair the function
of the emission control system and could lead
to damage.
fDo not alter or remove any component of the
emission control system.
fDo not alter or remove any device, such as
heat shields, switches, ignition wires, valves,
etc., which are designed to protect your vehic-
le’s emission control system.
In addition to serious engine damage, this can
result in a fire if excess raw fuel reaches the ex-
haust system.
fDo not continue to operate your vehicle if you
detect engine misfire or other unusual opera-
ting conditions.
Parking
Warning!
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
other flammable material.
fIf your car catches on fire for any reason, call
the fire department.
Do not endanger your life by attempting to put out the fire.
Undercoating
Danger!
Danger of fire and serious personal injuries
or death.
fDo not apply additional undercoating or rust-
proofing on or near the exhaust manifold, ex-
haust pipes, catalytic converters or heat
shields. During driving the substance used for undercoating could overheat and ignite.

Maintenance, Car Care
Cleaning and preserving 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 engi-
ne 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.
Caution!
Risk of damage to the alternator.
fDo not point the cleaning jet directly at the al-ternator, or cover the alternator.
Effective corrosion-proofing is particularly impor-
tant during the cold weather season. If your car is
driven frequently in areas where salt has been
spread on the roads, the whole engine compart-
ment should be cleaned thoroughly after the win-
ter to prevent salt from causing any lasting dama-
ge. A full under-body wash should also be perfor-
med at the same time.
Windows The road dust which settles on the windshield and
windows contains particles of tire rubber and oil
residue. The interior trim and upholstery release
particles, particularly in strong sunlight, which col-
lect on the insides of the windows. These deposits
are augmented by impurities in the air which en-
ters the car through the fresh air vents.
fClean all windows regularly, inside and outside,
with Porsche window cleaner.
fIf you use a chamois leather for the windows,
do not use it for paintwork as it will otherwise
pick up a certain amount of preservative or po-
lish and could smear the windows and thus im-
pair vision.
fRemove dead insects with the Porsche insect
remover.
Note
Door windows feature a water-repellent (hydropho-
bic) coating which prevents soiling of the windows.
This coating is subject to natural wear and can be
renewed.
fConsult an authorized Porsche dealer.
Wiper blades Wiper blades that are in perfekt condition are vital
for a clear view.
fReplace the wiper blades twice per year (be-
fore and after the cold season) or whenever wi-
per performance deteriorates.
fPeriodically clean the wiper blades with
Porsche window cleaner, especially after the
vehicle has been washed in a car wash.
If they are very dirty (e.g. with insect remains),
they can be cleaned with a sponge or cloth. Undercoating The underside of your car is durably protected
against chemical and mechanical influences.
As it is not possible to exclude the risk of damage
to this protective coating in day to day driving, it
is advisable to have the underside of the car in-
spected at certain intervals - preferably before the
start of winter and again in spring - and the under-
coating restored as necessary.
Your authorized Porsche dealer is familiar with the
bodyseal treatment procedures and has the ne-
cessary equipment for applying factory approved
materials. We recommend that you entrust them
with such work and inspections.
Unlike conventional spray oils, undercoating and
rust-proofing compounds based on bitumen or
wax do not attack the sound-proofing materials ap-
plied at the factory.

Maintenance, Car Care
Storing your Porsche If you intend to store your Porsche for a prolonged
period, please consult your authorized Porsche
dealer. The staff will be glad to advise you on the
most suitable and necessary methods.
fClean your vehicle thoroughly inside and out-
side.
Clean the engine compartment.
The under carriage and chassis components
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 58 psi (4 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 wor-
king 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 observe the chapter “BULB CHART” on
Page 259. 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, lids and top must be closed. The
air vents should be opened.
