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. 
f Always monitor your fuel consumption. 
f Drive smoothly, avoid abrupt changes in speed 
as much as possible. 
f Avoid jack rabbit starts and sudden stops. 
f Do not drive longer than necessary in the lower 
gears. Shifting into a higher gear early without 
lugging the engine will help save fuel. 
f Prolonged “warm up” idling wastes gas. Start 
the vehicle just before you are ready to drive. 
Accelerate slowly and smoothly. 
f Switch off the engine if  stationary for longer 
periods.  f
Any additional weight carried in the vehicle re-
duces fuel economy. Always keep cargo to a 
minimum and remove all unnecessary items. 
f Organize your trips to take in several errands 
in one trip. 
f All electrical accessories contribute to in-
creased fuel consumption. 
f Only switch on the air conditioning when neces-
sary. 
f Do not drive with the Ro of 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. 
f Please 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 ma y be inadequa 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.
