Information on air-conditioning
compressor– May switch off briefly to ensure sufficient
engine cooling if the engine is operating under
extreme load.
– Operates most effectively with the windows
closed.
If the vehicle 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
humidity, condensation can drip from the
evaporator and form a pool under the car.
This is normal and not a sign of leakage.
– If uncooled air flows out when the lowest
temperature has been set, switch off the air
conditioning compressor and have the fault
remedied.
Please contact your authorized Porsche dealer
for further information.

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 resul-
ting in serious personal injury or death.
fOperate the components while driving only if
the traffic situation allows you to do 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.
Accessories which have not been tested and
approved by Porsche may impair radio function
and reception.
NavigationWhen put into operation for the first time, a
distance of approx. 31 miles (50 km) must be dri-
ven in order for the navigation system to complete
the process of fine calibration.
The same applies when the tires are changed (e.g.
summer/snow 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 after
being switched on before it determines the current
location.
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 becomes operational again.

232. 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 appro-
ved by Porsche may impair radio function and re-
ception. Fading and drifting
FM range is limited to about 25 miles (40 km), ex-
cept for some high power stations.
If a vehicle is moving away from the desired stati-
on’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 adjus-
ting the tone control for greater bass response un-
til the disturbance has passed. Multipath
Because of the reflecting characteristics of FM, di-
rect 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, someti-
mes 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
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 to the correct pres-
sure.
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 (traffic lights, jams, level crossings). 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.
The EPA estimated m.p.g. is to be used for
comparison purposes, actual mileage may
be different from the estimated m.p.g., de-
pending on your driving speed, weather con-
ditions and trip length. Your actual highway
mileage will probably be less than the esti-
mated m.p.g.
fPlease observe all local and national speed lim-
its.

Emission Control System In the interest of clean air Pollution of our environment has become a prob-
lem 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 serv-
ice for the vehicle and to keep a record of all main-
tenance work performed. To facilitate record
keeping, have the service performed by author-
ized 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 de-
scribed in your Maintenance Booklet.
Lack of proper maintenance, as well as im-
proper use of the vehicle, will impair the func-
tion 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 vehi-
cle’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 operat-
ing 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 oth-
er 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.

How Emission Control Works When an automobile engine is running, it uses en-
ergy generated through the combustion of a mix-
ture of air and fuel. Depending on whether a car is
driven fast or slowly or whether the engine is cold
or hot, some of the fuel (hydrocarbons) may not
be burned completely, but may be discharged into
the engine crankcase or exhaust system. Addition-
al hydrocarbons may enter the atmosphere
through evaporation of fuel from the fuel tank.
These hydrocarbons (HC), when released into the
air, contribute to undesirable pollution.
In addition, carbon monoxide (CO) and oxides of
nitrogen (NOx) contribute to engine emissions.
They, too, are formed during the combustion proc-
ess and discharged into the exhaust system.
To reduce these pollutants, your Porsche is
equipped with a precisely calibrated fuel injection
system to assure a finely balanced air/fuel mixture
under all operating conditions. Oxygen sensor The oxygen sensor, installed in the exhaust pipe
continuously senses the oxygen content of the ex-
haust and signals the information to an electronic
control unit. The control unit corrects the air/fuel
ratio, so the engine always receives an accurately
metered air/fuel mixture.
Crankcase ventilation Through crankcase ventilation, undesirable emis-
sions from the engine crankcase are not permit-
ted to reach the outside atmosphere. These emis-
sions are recirculated from the crankcase to the
air intake system. From here the emissions mix
with the intake air and are later burned in the en-
gine. Catalytic converters The catalytic converters are efficient ”clean-up“
devices built into the exhaust system of the vehi-
cle. The catalytic converters burn the undesirable
pollutants in the exhaust gas before it is released
into the atmosphere.
The exclusive use of unleaded fuel is critical-
ly important for the life of the catalytic con-
verters. Therefore, only unleaded fuel must
be used.
The catalytic converters will be damaged by:
– push or tow starting the vehicle,
– misfiring of the engine,
– turning off the ignition while the vehicle is mov-
ing or
– driving until the fuel tank is completely empty,
– by other unusual operating conditions. fDo not continue to operate your vehicle under
these conditions, since raw fuel might reach
the catalytic converters. This could result in
overheating of the converters. Federal law pro-
hibits use of leaded fuel in this car.
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 fWhen the engine is running, the fuel vapors
from the canister will be mixed with fresh air
from the ambient air of the canister. This mix-
ture will be directed to the intake air housing by
the tank vent line, mixed with the intake air and
burned during normal combustion.
