Driving on racetracks puts high pressure on brake
pads and brake disks.
e If the brake fluid is more than 12 months old:
Replace brake fluid before driving on a track.
e
Have the brake pads and brake disks checked for
wear before and after driving on tracks.
Tires
The tires are also subject to high stress when the
vehicle is driven around a track.
e Have the tires checked for wear before and after
driving on tracks.
e Do not fit racing tires. Racing tires are not ap-
proved by Porsche.
Engine oil
e Add engine oil up to the maximum mark before
driving on tracks.
e Check the engine oil level before and after driving
on tracks.
>
Please see chapter "Engine Oil" on page 123.
Central lock
e Check the tightening torque of the central bolts
before and, if necessary, during and after driving
on racetracks.
e After every racetrack operation check all com-
ponents of the central lock for wear and, if nec-
essary, replace.
> Please see chapter "Changing wheels with a
central lock" on page 311.

sports driving training, motorsport events)" on
page 319.
Before driving abroad
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 seri-
ous damage to both engine and catalytic con-
verters could result,
– Service may be inadequate due to lack of proper
service facilities, tools or diagnostic equipment,
– Replacement parts may not be available or very
difficult to get.
– The authorized Porsche dealer may not be able to
carry out all repair work.
– Technical adjustments need to be made to the
vehicle,
– Some countries require additional tools and spe-
cial spare parts to be carried in your vehicle,
make enquiries before driving abroad.
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 current
import and customs regulations.
Data processing in the vehicle
Electronic control units are installed in your vehicle.
Some of these are required for the operational safety
of your vehicle, while others provide assistance while
driving (driver assistance systems). Moreover, your
vehicle offers comfort and entertainment functions
which are also made possible through electronic
control units.
Storing technical data in the vehicle
Electronic control units have data memories that can
temporarily or permanently store technical informa-
tion about vehicle status, component stress, servic-
ing requirements, events or faults. Generally
speaking, this technical information documents the
status of a component, module, system or environ-
ment such as:
– Operating states of system components (e.g. fill
levels)
– Status messages about the vehicle and its indi-
vidual components
– Malfunctions and faults in important system
components (e.g. lights, brakes)
