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.
