The warning light in the instrument panel comes
on when the ignition is first turned on and remains
on briefly as a bulb check. If the light does not
come on, have the bulb replaced promptly.
If the warning lights in the instrument panel and on-
board computer come on and remain on while
driving, it suggests:
– a potential engine control problem and the
need for system service or
– an improperly fastened tank cap or
– refuelling with engine running.
Although the vehicle is usually driveable and will
not require towing, see your dealer for service as
soon as possible.
Caution!
If the Check engine light in the instrument
panel is flashing, severe catalytic converter
damage and power loss will soon occur.
Prolonged driving with the Check engine light
on could cause damage to the emission con-
trol system. It also could affect fuel economy
and driveability.
fHave the fault remedied at the nearest author-ized 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 observe the chapter “INFO WARNING
MESSAGES” on Page 102.
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 observe the chapter “WARNINGS ON

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.

Controls, Instruments Tire pressure function of the on-board
computer
The tire pressure function of the on-board
computer displays the tire pressures (actual
pressure) dependent on temperature in the four
wheels.
You can watch the tire pressure rise as the
temperature increases while driving.
This display is only for information.
fUnder no circumstances should the tire
pressures be changed based on this display.
Displaying the tire pressure function of the
on-board computer
fPush operating lever up or down until the tire
pressure function of the on-board computer
appears.
(The selection field must be switched off.)Pressure info in Tire pressure menu
In accordance with physical principles, the air
pressure changes as the temperature changes.
The tire pressure increases or decreases by
around 1.5 psi (0.1 bar) for every 18°F (10°C)
change in temperature.
The tire pressure monitoring takes this relation-
ship between tire pressure and temperature into
account.
You can read the tire pressures to be
corrected in this display.
The tire pressure to be corrected (refill pressure)
is indicated on the displayed wheel.
Example: If “ –1.5 psi (–0.1 bar)” is displayed,
1.5 psi (0.1 bar) must be added to this tire.
Note
The Tire pressure menu can only be called up
when the vehicle is stationary.Calling up the “Info pressure” display
fPush operating lever forward in order to switch
on the selection field.
fSelect “TPC” with the operating lever.
fPush operating lever forward.
The display changes to the Tire pressure
menu.
fSelect “Info pressure” with the operating lever.
fPush operating lever forward.
Note
After the ignition is switched on, it can take up to
approx. 1 minute before all tire pressures are
displayed. Dashes (“-.-”) appear instead of the tire
pressures.

System learningThe tire pressure monitoring begins to “learn” the
wheels after a wheel change, wheel transmitter
replacement or update of the tire settings. During
this process, the tire pressure monitoring recog-
nises the tires and their locations. The on-board
computer displayes the message “TPC inactive –
system learning”.
The tire pressure monitoring requires a certain
amount of time to learn the wheels. During this
time, the current tire pressures are not available
on the on-board-computer:
– The display of the Tire pressure function of the
on-board computer shows lines.
– The required pressures for cold tires at 68°F
(20°C) are indicated in the Info pressure
display in the Tire pressure menu.
– Tire pressure warnings are issued without tire
pressure and position information (figure) as
soon as the vehicle’s own wheels have been
detected and the tire pressure warning light
has gone out.Position and pressure information is displayed as
soon as the tire pressure monitoring has assigned
the wheels identified as belonging to the vehicle to
the correct wheel positions.
The wheel learning process takes place
exclusively when the vehicle is being driven.
fManually check the tire pressure at all wheels
and correct the tire pressure to the required
value.
Changing a wheel and replacing tiresfNew wheels must be fitted with radio transmit-
ters for the tire pressure monitoring.
Before tires are changed, the battery charge
state of the wheel transmitters should be
checked at an authorized Porsche dealer.
fSwitch the ignition off when changing a wheel.
The tire settings on the on-board computer must
be updated after changing a wheel.
A message appears if the characteristics of the
new tires do not agree with the on-board computer
settings.
fUpdate the on-board computer settings when
the vehicle is stationary the next time.

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.
