General instructions for air-conditioning
compressor– Can switch off briefly if engine is under an ex-
treme load to ensure sufficient engine cooling.
– Switches off automatically at temperatures be-
low approx. 37°F/3°C and cannot be switched
on, even manually.
– Operates most effectively with windows
closed.
If the car has been in the sun for a long time, it
is a good idea to ventilate the interior briefly
with the windows open.
– Depending on the outside temperature and hu-
midity, condensation can drip from the evapo-
rator and form a pool under the vehicle.
This is normal and not a sign of leakage.
– If uncooled air flows out when the lowest tem-
perature has been set, switch off the air-condi-
tioning compressor and have the fault repaired
at an authorized Porsche dealer. Air distribution to footwell

Warning!
There is a danger of accident if you set or
operate the on-board computer, radio, navi-
gation system, telephone or other equipment
when driving.
This could distract you from the traffic and
cause you to lose control of the vehicle re-
sulting in serious personal injury or death.
fOperate the components while driving only if
the traffic situation allows you to do so safely.
fCarry out any complicated operating or setting procedures only with the vehicle stationary.The reception conditions for the radio module inte-
grated in the PCM change continuously as you
drive. Interference from buildings, terrain and the
weather is unavoidable.
FM stereo reception is particularly susceptible to
varying reception conditions.
Electronic accessories should only be retrofitted
by a qualified specialist workshop.
Accessories which have not been tested and
approved by Porsche may impair radio reception.
NavigationWhen put into operation for the first time, a
distance of approx. 30 miles (50 km) must be
driven in order for the navigation system to
complete the process of fine calibration.
The same applies when the tires are changed (e.g.
summer/winter tires) or new tires fitted.
Full location accuracy is not yet achieved during
the fine-calibration process.
If the vehicle has been transported (e.g. ferry, car
train), the system may take a few minutes to deter-
mine the current location after it has been
switched on.
Serious tire slip (e.g. spinning wheels on snow)
may result in temporarily inaccurate navigation.
When the battery has been disconnected, it may
take up to 15 minutes before the navigation
system is operational again.

Car Audio Operation/Tips FM reception
A vehicle is not an ideal place to listen to a radio.
Because the vehicle moves, reception conditions
are constantly changing.
Buildings, terrain, signal distance and noise from
other vehicles are all working against good recep-
tion.
Some conditions affecting FM may appear to be
problems when they are not.
The following characteristics are completely nor-
mal for a given reception area, and they do not in-
dicate any problem with the radio itself.
Note
Electronic accessories should only be installed by
your authorized Porsche dealer.
Equipment which has not been tested and ap-
proved by Porsche may impair radio reception. Fading and drifting
FM range is limited to about 25 miles (40 km),
except for some high power stations.
If a vehicle is moving away from the desired sta-
tion’s transmitter, the signal will tend to fade and/
or drift. This condition is more prevalent with FM
than AM, and is often accompanied by distortion.
Fading and drifting can be minimized to a certain
degree by careful attention to fine tuning or selec-
tion of a stronger signal.
Static and fluttering
When the line-of-sight link between a transmitter
and vehicle is blocked by large buildings or moun-
tains, the radio sound may be accompanied with
static or fluttering because of the characteristic of
FM.
In a similar effect, a fluttering noise is sometimes
heard when driving along a tree-lined road.
This static and fluttering can be reduced by adjust-
ing the tone control for greater bass response un-
til the disturbance has passed. Multipath
Because of the reflecting characteristics of FM,
direct and reflected signals may reach the antenna
at the same time (multipath) and cancel each other
out.
As a vehicle moves through these electronic dead
spots, the listener may hear a momentary flutter
or loss of reception.
Station swapping
When two FM stations are close to each other, and
an electronic dead spot, such as static or multi-
path area, interrupts the original signal, some-
times the stronger second signal will be selected
automatically until the original one returns.
This swapping can also occur as you drive away
from the selected station and approach another
station of a stronger signal.

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 Economy Fuel economy will vary depending on where,
when and how you drive, optional equipment
installed, and the general condition of your
car.
A car tuned to specifications and correctly
maintained, will help you to achieve optimal
fuel economy.
fHave your vehicle tuned to specifications.
Air cleaner should be dirt free to allow proper
engine “breathing”.
Battery should be fully charged.
Wheels should be properly aligned.
Tires should be inflated at correct pressure.
fAlways monitor your fuel consumption.
fDrive smoothly, avoid abrupt changes in speed
as much as possible.
fAvoid jack rabbit starts and sudden stops.
fDo not drive longer than necessary in the lower
gears. Shifting into a higher gear early without
lugging the engine will help save fuel.
fProlonged “warm up” idling wastes gas. Start
the vehicle just before you are ready to drive.
Accelerate slowly and smoothly.
fSwitch off the engine if stationary for longer
periods. fAny additional weight carried in the vehicle re-
duces fuel economy. Always keep cargo to a
minimum and remove all unnecessary items.
fOrganize your trips to take in several errands
in one trip.
fAll electrical accessories contribute to in-
creased fuel consumption.
fOnly switch on the air conditioning when neces-
sary.
fDo not drive with the Roof Transport System
mounted unless you need it.
The EPA estimated m.p.g. is to be used for
comparison purposes, actual mileage may
be different from the estimated m.p.g.,
depending on your driving speed, weather
conditions and trip length. Your actual
highway mileage will probably be less than
the estimated m.p.g.
fPlease observe all local and national speed
limits.
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 prop-
er service facilities, tools or diagnostic equip-
ment;
– replacement parts may not be available or very
difficult to get.
Porsche cannot be responsible for the
mechanical damage that could result
because of inadequate fuel, service or parts
availability.
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.
