gine compartment lid closed during operation
of the convertible top with the rocker switch?
Are electrical fuses defective?
Please observe the chapter “ELECTRICAL SYS-
TEM” on Page 232.

Maintenance, Car Care
Changing the brake fluid Brake fluid absorbs moisture from the air over
time. This accumulation of water lowers the boil-
ing point and, under certain operating conditions,
can affect the braking action.
Therefore have the brake fluid changed in accord-
ance with the change intervals stated in the
brochure “Maintenance”. – The warning lights on the instrument panel and
on the on-board computer indicate an insuffi-
cient brake fluid level.
– If the warning light lights up on the instrument
panel and the warning message appears on
the on-board computer in combination with a
larger pedal travel, a brake circuit may have
failed.
If the warning lights should light up whilst
driving:
fStop immediately in a suitable place.
fDo not continue driving.
Consult an authorized Porsche dealer.

Fuel
Warning!
Fuel is highly flammable and harmful to
health.
fFire, open flame and smoking are prohibited
when handling fuel.
fAvoid contact with skin or clothing.
fDo not inhale fuel vapors.
To prevent damage to the emission control
system and engine:
fNever drive the tank completely out of fuel.
fAvoid high cornering speeds after the warning lights have come on.
fPlease observe the chapter “EMISSION CONT-
ROL SYSTEM” on Page 191.
Please observe the chapter “FUEL ECONOMY”
on Page 187.
Please observe the chapter “LEVEL GAUGE”
on Page 86.
Check engine warning light
If the warning lights in the instrument panel and on-
board computer come on and remain on while
driving, it suggests:
– an improperly fastened tank cap or
– refuelling with engine running.
Opening the filler flap The filler opening is under the filler flap in the front
right fender.
fWith the vehicle unlocked, press on the front
part of the filler flap (arrow) to open the flap.
The filler flap is centrally locked along with the oth-
er locks. If there is a defect in the automatic unlocking
system:
fOpen the passenger door.
fPull the ring in the right-hand door aperture
(arrow).

Maintenance, Car Care 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 (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 meth-
anol 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 prob-
lems 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.
Fuels containing MMT Some North American fuels contain an octane en-
hancing additive called methylcyclopentadienyl
manganese tricarbonyl (MMT).
If such fuels are used, your emission control sys-
tem performance may be negatively affected.
The check engine warning light on your instrument
panel may turn on.
If this occurs, Porsche recommends you stop us-
ing fuels containing MMT.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.
fNever carry additional fuel in portable contain-ers in your vehicle. RON+MON

Practical Tips, Emergency Service

Replacing battery The service life of the battery is subject to normal
wear; it depends greatly on care, climatic condi-
tions, and driving conditions (distances, loads).
fOnly use an original Porsche battery, with the
correct part number, as a replacement.
fPlease observe the disposal instructions for
batteries.
Putting vehicle into operationAfter the battery is connected or after an exhaus-
tively discharged battery is charged, the multi-
functional PSM light lights up on the instrument
panel and a message appears on the on-board
computer to indicate a fault.
This fault can be remedied with a few simple
steps:
1. Start the engine.
2. With the vehicle stationary, perform a few
steering movements to the left and right and
then drive a short distance in a straight line
until the multifunctinal PSM light goes out and
the message on the on-board computer
disappears.
3. If the warnings do not disappear, then:
Drive carefully to the nearest authorized
Porsche dealer.
Have the fault remedied.
4. After the warnings disappear:
Stop the vehicle in a suitable place.
fPerform adaptation of the power windows:
Please observe the chapter “STORING END
POSITION OF THE WINDOWS” on Page 29.Ignition key/ignition lock
fDo not insert the ignition key into the ignition
lock if the vehicle battery is discharged.
The ignition key can no longer be removed.
The key cannot be removed until the vehicle elec-
trical system is supplied with power again.
fPlease observe the chapter “EMERGENCY UN-
LOCKING OF THE LUGGAGE COMPARTMENT
LID” on Page 235.
fPlease observe the chapter “EMERGENCY
STARTING WITH JUMPER CABLES” on
Page 242.
