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 (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 increa-
sed 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 li-
mits. 
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
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 239. 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.
