Break-in Hints
for the first 1.000 miles/
1.600 kilometers
There are no specific break-in rules for your
Porsche; however, by observing a few pre-
cautions during the first miles, you can in-
crease the service life and performance of
your engine.
During the first 1.000 miles/1.600 km,
w o r k i n g components of the engine adjust to
each other to a certain degree. Therefore:
A v o i d full throttle starts and abrupt stops.
Change speeds frequently. Vary the throttle
load.
Do not exceed max. engine speed of 5.000
rpm (revolutions per minute).
Do not run a cold engine at high rpm or in
Neutral.
Do not let the engine labor, especially when
driving uphill. Shift to the next proper gear
in time (use the most favorable rpm range).
There may be as slight stiffness in the steer-
ing, gearshifting or other controls during the
break-in period, which will gradually dis-
appear.
Never lug the engine in high gear at low
speeds. This rule applies all the time, not
just during the break-in period.
Maximum engine speed
The red mark on the tachometer dial serves
as an optical reminder not to overrev the en-
gine. The speed limiting governor prevents
all
overrevving the engine under load by limit-
ing the engine speed. The tolerance of the
speed governor is + 200 rpm.
Breaking in brake pads
Brake pads do not have maximum braking
efficiency when the car is new. Therefore
more pedal force is necessary during the
first 120 miles/200 km. This also applies to
replacement brake pads.
Breaking in new tires
N e w tires do not have maximum traction.
They tend to be slippery. Break in new tires
by driving at moderate speeds during the
first 60 to 120 miles/100 to 200 k m .
