General information regarding the
on-board computer functionsRange on remaining fuel
The range on remaining fuel is continuously recal-
culated during the journey based on the fuel level,
current consumption and average consumption.
The more the fuel level falls, the more spontan-
eously the display reacts. For this reason, the
range on remaining fuel is not displayed if less
than 9 miles (15 kilometers).
If the vehicle's inclination changes while driving or
refuelling, incorrect range information may tempo-
rarily be given.
Note
If the tank is nearly empty and you top up with only
a small quantity of fuel, an accurate range on re-
maining fuel is impossible.Average consumption and average speed
The values displayed are based on the distance
travelled since the last reset to “zero”.
You can set the starting time for a measurement
before or during the trip.
Switching the ignition off does not reset the meas-
urements. It is therefore possible to collect values
over long periods.
Disconnecting the car battery will cause these
memories to be erased.

Shifting Gear
Manual Transmission, ClutchThe positions of the gears are shown on the shift
diagram on the gearshift lever.
Warning!
Risk of accident.
fDo not obstruct the pedal travel with floor mats
or other objects.
Nonskid floor mats of the correct size are
available at your authorized Porsche dealer.
To avoid damage to the clutch and transmis-
sion:
fAlways depress the clutch pedal fully when
changing gears. Make sure that the gearshift
lever is completely engaged.
fOnly shift into reverse when the car has come to a complete stop.fWhen shifting gears, always ensure that the
clutch pedal is fully depressed and the gear
has fully engaged.
fSelect reverse only when vehicle is stationary.
fSelect an appropriately low gear on upward
and downward slopes.
This will ensure optimum use of engine power
and engine braking.
When reverse gear is selected and the ignition is
on, the backup lights are illuminated.
Permitted engine speedfYou should change into a higher gear before
the needle reaches the red mark on the ta-
chometer, or ease off the accelerator.
If the red zone is reached during acceleration, fuel
feed is interrupted.
Caution!
Risk of engine damage (overrevving) when
shifting down to a lower gear.
fTake care not to exceed the maximum permit-ted engine speed when shifting down.
