Safety and Driving Pleasure
Running in the vehicle
The moving parts of a new vehicle must be run in. The
parts require the first 2,000 miles (3,000 km) for this
purpose. The oil and fuel consumption may be
somewhat higher than normal during this period.
During the running-in period, drive as follows:
e
Preferably take long trips. Avoid frequent cold
starts with short-distance driving whenever
possible.
e
Avoid full throttle starts and abrupt stops.
e
Do not participate in motorsport events, sports
driving training or similar events.
e
Avoid high engine speeds of 4,000 rpm or more.
Drive at low engine speeds when the engine is
cold.
e
Do not let the engine labor, especially when
driving uphill. Shift to the next lower gear in time
(use the most favorable rpm range).
e
Never lug the engine in high gear at low speeds.
This rule applies at all times, not just during the
break-in period.
There may be a slight stiffness in the steering gear-
shifting or other controls during the break-in period
which will gradually disappear.
Running in new brake pads
New brake pads and brake disks have to be “bedded
in” and therefore only attain optimal friction when the
vehicle has covered several hundred miles.
The somewhat reduced braking effect requires more
effort when braking. This is also the case after the
brake pads or brake disks have been replaced.
Observing the ground clearance
The vehicle may touch the ground as a result of the
low ground clearance.
e
Avoid steep ramps.
e
Drive carefully on the following:
– Steep slopes (e.g. parking garages)
– Curbs
– Uneven road surfaces
– Lifting platforms
Driving on race circuits
Compared to normal road use, when driving on
circuits the vehicle is subjected to disproportionately
higher loads. In pure racing vehicles these loads are
taken account of by regular maintenance and
component reconditioning intervals. These cover
checks and the replacement of individual compo-
nents where necessary after each use on the circuit,
as well as the reconditioning of entire assemblies
after certain periods of use.
e
Always make inquiries about the current stipula-
tions before driving on race circuits: Contact an
authorized Porsche dealer.
Following race circuit sessions, “cooling laps” must
be performed to control the temperature reduction of
chassis components which are subjected to particu-
larly strong thermal load. Instantaneous stopping of
the vehicle would result in a further rise in component
temperature due to stationary heat build-up. This can
irreparably damage individual components.
Brake system
Brake fluid absorbs moisture from the air over time.
This absorption of water lowers the boiling point and
can severely impair braking efficiency at high
temperatures.
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 circuit.
