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.

Instruments, On-Board Computer, Warnings The oil pressure is controlled as required and
should be at least 3.5 bar at an engine speed of
5000 rpm.
The engine oil pressure varies depending on the
engine speed, engine load and engine tempera-
ture.If oil pressure drops abruptly and a message
is displayed on the on-board computer when
the engine is running on or when driving:
fStop immediately in a suitable place.
fSwitch off the engine.
fCheck whether there is an obvious oil leak on
or under the car.
fIf no oil leak can be detected: With the engine
idling, measure the oil level with the on-board
computer.
fPlease see the chapter “OIL DISPLAY AND
MEASUREMENT OF THE ENGINE OIL LEVEL”
on Page 153.
fPlease see the chapter “ENGINE OIL LEVEL”
on Page 208.
fAdd engine oil if necessary.
Caution!
Risk of engine damage.
fDo not continue driving if there is an obvious oil
leak.
fDo not continue driving if the warning lights
come on even though oil level is correct.
fHave the fault remedied at the nearest authorized Porsche dealer.If the battery voltage drops abruptly, a warning
message will be displayed by the on-board compu-
ter.
If the warning is displayed by the on-board
computer while the engine is running or while
driving:

engine.
Possible causes
– Defect in the battery charging system.
– Broken drive belt.
Warning!
Risk of engine damage with resultant loss of
control and accident, leading to serious per-
sonal injury or death.
A broken drive belt means there is no power
assistance to the steering (more effort is re-
quired to steer) and coolant pump function
will stop.
fDo not continue driving.

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.

154
Instruments, On-Board Computer, Warnings 6. If the segments are filled in up to the top line,
the oil level has reached the maximum mark.
Under no circumstances add engine oil.7. If the bottom segment is filled in, the oil level
has reached the minimum mark.
Add engine oil immediately.
8. If the bottom segment flashes, the oil level has
dropped to below the minimum mark.
Add engine oil immediately.
The difference between the minimum and
maximum marks on the segment display is
approx. 1.3 quarts (1.25 litres).
One segment of the display corresponds to a
top-up quantity of approx. 0.42 quarts (0.4 litre).
fAdd engine oil if necessary.
Switch off ignition before adding engine oil.fPlease see the chapter “ENGINE OIL LEVEL”
on Page 208.
fNever add more engine oil than required
to reach the maximum mark.
Failure
A failure of the oil level display is indicated by a
warning message on the on-board computer.
“Check engine oil level” display
The on-board computer display “Check engine oil
level” is an additional measurement that takes
place in the background while driving.
The display depends on the distance travelled.
This display appears if the oil level has reached the
minimum mark or if the oil level is well above the
maximum mark.
This message must be acknowledged by
measuring the engine oil level manually using the
on-board computer.
fPlease see the chapter “INITIATING OIL LEVEL
MEASUREMENT” on Page 153.
If oil level measurement was initiated manually on
the on-board computer and no oil was added, the
message “Check engine oil level” is displayed
again when the vehicle is driven.
