Tachometer The tachometer shows the engine speed in revolu-
tions per minute (rpm).
The beginning of the red marks at the right end of
the scale indicates the maximum permissible en-
gine rpm.
A speed limiter prevents the engine from being
overrevved during acceleration. Before reaching
this area, the next higher gear should be select-
ed.
Shift to the next lower gear when the engine rpm
drops below 1,500 rpm.
Caution!
To avoid severe engine damage.
fAlways observe the engine rpm before down-
shifting to a lower gear, so you do not exceed the maximum engine rpm.
Flashes in synchronism with the turn signals.
Left arrow – left turn signals
Right arrow – right turn signals
fIf the frequency of the display becomes notice-
ably faster, check the operation of the turn sig-
nals.
Lights when high beam or headlight flasher is
switched on.
The indicator light goes out when the high beams
are switched off.
The indicator light flashes in the event of cornering
light failure.
Gear Shift Indicator “A”(in vehicles with manual transmission)The consumption-orientated gear shift indicator A
on the display panel of the on-board computer
assists a fuel-saving driving style. The gear shift
indicator lights up as a recommendation to shift
up to the next-higher gear depending on the
selected gear, engine rpm and accelerator pedal
position.
fWhen the gear shift indicator A lights up,
change to the next higher gear to decrease
fuel consumption.

Check Engine
(Emission Control)The emission control system detects malfunctions
early that could, for example, cause increased
pollutant emissions or consequential damage.
Faults are indicated by a continuously lit or
flashing instrument panel warning light.
The faults are recorded in the control unit's fault
memory.
The warning light in the instrument panel lights up
when the ignition is switched on as a bulb check
and goes out approx. 4 seconds after the engine
starts. If the warning light does not light up, have
the bulb replaced promptly.
The warning light in the instrument panel flashes to
indicate operating states (e.g. engine misfiring)
which might cause damage to certain parts of the
emission control system.
fIn this case, immediately reduce the engine
load by easing off the accelerator.
fIn order to avoid consequential damage to the
engine or emission control system (e.g. cata-
lytic converter), have the fault diagnosed and
rectified immediately at the nearest authorized
Porsche dealer.If the warning light in the instrument panel lights up
permanently without flashing before and remains
on while driving, it suggests:
– a potential engine control problem and the
need for system service or
– an improperly fastened tank cap or
– the vehicle was refueled while the engine was
running.
fStop immediately at a suitable and secure
place and check tank cap for proper fastening.
If tank cap was fastened correctly, see your au-
thorized Porsche dealer for service as soon as
possible.
Caution!
If the check engine warning light in the in-
strument panel is flashing, serious catalytic
converter damage and power loss will soon
occur.
Prolonged driving with the check engine war-
ning light on could cause damage to the
emission control system. It also could affect
fuel economy and driveability.
fHave the fault remedied at the nearest authorized Porsche dealer immediately.The central warning light on the instrument panel
lights up if there are warning messages in the
INFO menu.
The messages can be called in the on-board
computer INFO menu:
fPlease see the chapter “INFO WARNING MES-
SAGES” on Page 132.
The warning light on the instrument panel lights
up:
– if the handbrake is on,
– if the brake fluid level is low,
– if the brake pads have reached the wear limit,
– if the brake circuit division is defective.
Additionally, a warning is displayed by the on-
board computer.
fPlease see the chapter “WARNINGS ON THE
INSTRUMENT PANEL AND THE ON-BOARD
COMPUTER” on Page 158.

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.

puter display changes to the “Continue/Reset” se-
lection.
fSelect “Reset” with the operating lever.fPush operating lever forward.
The display returns to the “Start timing”
selection.

The on-board computer display then returns to the
“Stop timing/Intermediate time” selection.
fYou can stop the stopwatch or measure anoth-
er intermediate time.In order to start timing a new lap:
The “New lap?” selection appears for 5 seconds
after selection of “Intermediate time”.
fSelect “New lap?” with the operating lever and
push the operating lever forwards.The new lap is displayed on the on-board compu-
ter and the PCM. Timing on the on-board computer
and on the PCM begins from zero. The stopwatch
in the instrument panel continues to show the total
time.
