CHRONO
StopwatchYou can use the stopwatch to measure time inter-
vals, e.g. on the race circuit or on work-related
journeys. Measured lap times can be stored and
evaluated if the vehicle is equipped with Porsche
Communication Management (PCM).
fPlease observe the chapter “Sport display” in
the separate PCM operating instructions.Stopwatch on the instrument panel
The stopwatch has an analogue and a digital dis-
play.
The large pointer of the analogue display meas-
ures the seconds. The two small pointers measure
hours and minutes. The display re-starts at zero af-
ter 12 hours.
Seconds and increments of 1/100th of a second
can be read on the digital display.
The digital display and the display in the on-board
computer can indicate up to 99 hours and
59 minutes.
The stopwatch can be swivelled both to the left
and to the right.
Stopwatch displays:
– on the stopwatch on the instrument panel,
– in the on-board computer menu CHRONO,
– on the performance display in the PCM.
Starting/stopping stopwatch
All stopwatch displays are started and stopped via
the on-board computer menu CHRONO.Note on operation
When you leave the CHRONO menu while the stop-
watch is running, measurement will continue.
The stopwatch stops after the ignition is switched
off. If the ignition is switched on again within ap-
prox. 4 minutes, the stopwatch will continue to
run.
The only way to reset the stopwatch to zero is by
selecting “Reset” in the CHRONO menu.

OIL
Display and measurement of the engine
oil level
Caution!
Risk of engine damage.
fRegularly check the oil level after refuelling.
fDo not allow the oil level to fall below the mini-mum mark.
Conditions for measuring the oil level
1. It is important to ensure that the vehicle is
horizontal for correct oil level measurement
to occur.
2. Engine is off.
3. Ignition on.Oil return time
Before the oil level is measured, the engine oil has
to have flowed back into the oil pan.
The time taken for the engine oil to flow back de-
pends on the engine temperature and how long
the engine has been stopped.
This waiting time is counted down in the on-board
computer display when the ignition is switched on.
The oil level display segments start to “cycle”.
fIt is best to measure the engine oil level before
embarking on a journey (if the vehicle has not
been driven for an extended period) or with the
engine at operating temperature. Shorter wait-
ing times are achieved in this way.Initiating oil level measurement
fSwitch ignition on (do not start the engine).
The engine-oil level measurement display ap-
pears in the on-board computer.
fAllow waiting time to elapse.
fOnce the measurement has been completed,
you can read off the engine oil level on the seg-
ment display.
– If the segments are filled in up to the top line,
the oil level has reached the maximum mark.
fUnder no circumstances add engine oil.

102
Controls, Instruments – If the bottom segment is filled in, the oil level
has reached the minimum mark.
fAdd engine oil immediately.
– If the segment flashes, the oil level has
dropped to below the minimum mark.
fAdd engine oil immediately.
The difference between the minimum and maxi-
mum marks on the segment display is approx.
1.2 liters.
Each segment of the display corresponds to ap-
prox. 0.4 liter.
fAdd engine oil if necessary.
Please observe the chapter “ENGINE OIL LE-
VEL” on Page 181.
Before adding oil, switch ignition off.
fNever add more engine oil than required
to reach the maximum mark.Oil level measurement during refuelling
The oil level is automatically measured during re-
fuelling.
Preconditions
1. Ignition is switched off.
2. If the engine is at operating temperature, at
least 5 minutes must elapse between parking
the vehicle and starting the engine.
3. Refuelling completed within 15 minutes.
When the ignition is switched on, the engine oil lev-
el is shown on the segment display.
Measurement will be stopped if the above require-
ments are not met.
fStart oil level measurement in the “OIL“ menu
or
fStart oil level measurement by switching on
the ignition.
Failure
A failure of the oil level display is indicated by a
warning message in the on-board computer.The oil level measurement can also be
initiated in the “OIL” menu:
Switching on selection field “D”
fPush operating lever forward.
Initiating measurement
fSelect “OIL” with the operating lever.
fPush operating lever forward.
fSelect “Start” and push the operating lever for-
ward.
Measurement is started.

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.

Warnings on the instrument panel and the on-board computerIf a warning message appears, always refer to the corresponding chapters in the Owner’s Manual.
Warning messages are issued only if all measurement preconditions are met. Therefore, check all fluid levels regularly –
in particular, always check the engine oil level after refuelling.

Controls, Instruments Operational readiness of the emergency flasher
does not depend on the ignition lock and turn sig-
nal lever position.
fIf your car is disabled or parked under emer-
gency conditions switch on the emergency
flasher in the dashboard.
All turn signals and the indicator light in the
switch flash with the same frequency.
Warning!
Risk of an accident.
fWhenever stalled or stopped for emergency re-
pairs, move the car well off the road. Switch on
the emergency flasher and mark the car with
road flares or other warning devices.
fDo not remain in the car. Someone approach-
ing from the rear may not realize your vehicle
is stopped and cause a collision.
Danger of fire.
fDo not park or operate the vehicle in areas
where the hot exhaust system may come in
contact with dry grass, brush, fuel spill or
other flammable material.
Hot engine compartment components can
burn skin on contact.
fBefore working on any part in the engine com-
partment, turn the engine off and let it cool down sufficiently.
