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 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 mpg. is to be used for
comparison purposes, actual mileage may
be different from the estimated mpg.,
depending on your driving speed, weather
conditions and trip length. Your actual
highway mileage will probably be less than
the estimated mpg.
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;
– se rvice ma y be inade qua te 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.

Alcantara fDo not use a leather care product to clean
Alcantara.
For regular care it is sufficient to clean the cover
with a soft brush.
Heavy abrasion or rubbing when cleaning causes
a lasting change in the surface.
Cleaning when lightly soiled
fWet a soft cloth with water or a neutral soap
solution and wipe off the dirt.
Cleaning when heavily soiled
fWet a soft cloth with lukewarm water or
thinned white spirit and dab the dirt from the
outside in. Cleaning Safety belts fUse mild detergent to clean soiled belts.
fWhen drying, avoid direct sunlight.
fOnly use suitable cleaning agents.
fDo not tint or bleach the belts.
The belt fabric could be weakened, thus affec-
ting safety.
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 50 psi (3.5 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
working 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 see the chapter “BATTERY” on
Page 261.

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.
