Level gauge

When the ignition is on the fuel level is displayed.
fPlease observe the chapter “CAPACITIES” on
Page 271.
If the vehicle’s inclination changes (e.g. going up
or downhill), minor deviations in the indication may
occur. Note
If the tank is near empty and you top up with only
a small quantity of fuel, this cannot be registered
by the level gauge and calculation of the range re-
maining is impossible.
Warning light “A” When the engine is running, the warning light
of the level gauge lights up if less than approx.
2.6 U.S. gallons (10
liters) of fuel remains in the
tank or the range on remaining fuel falls below ap-
prox. 30 miles (50 km).
Additionally, a warning is displayed in the on-board
computer and the central warning light lights up.
fFill up at the next opportunity.
Caution!
To prevent damage to the emission control
system and engine.
fNever drive the tank completely out of fuel.
fAvoid high cornering speeds after the warning lights have come on.
fPlease observe the chapter “EMISSION CONT-
ROL SYSTEM” on Page 190.If the level gauge warning light flashes, there
has been a system fault.
Additionally, a warning is displayed in the on-board
computer.
There will then be no reserve warning.
fTo remedy the fault, go to an authorized
Porsche dealer.

ter.
If the warning is displayed by the on-board
computer while the engine is running or while
driving:
fStop the car in a safe place and stop the
engine.
Possible causes
– Defect in the battery charging system.
– Broken drive belt. Warning!
Risk of an accident and risk of engine dam-
age.
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.
fHave the fault remedied at the nearest author-ized Porsche dealer. 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
– refueling 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.

Operation, controlsIt is not possible to describe all details of the on-
board computer functions in this Owner’s Manual.
However, the examples will quickly familiarize you
with the operational principle and help you to
navigate through the menu structure.
You can restore the factory default settings at any
time by using the “SET” menu.

OIL
Display and measurement of the engine
oil level
Caution!
Risk of engine damage.
fRegularly check the oil level after refueling.
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.

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 178.
Before adding oil, switch ignition off.
fNever add more engine oil than required
to reach the maximum mark.Oil level measurement during refueling
The oil level is automatically measured during re-
fueling.
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. Refueling 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.
Measurement is started.

the accelerator.
The automatic speed control is operated with the
lever on the steering wheel.
Warning!
Risk of accident and consequent personal in-
jury. A constant speed may not be safe in
heavy traffic, or on winding or slippery
roads.
With the speed control system engaged, the
engine speed will not return to idle when re-
moving the foot from the accelerator pedal.
fDo not use the speed control when it may be
unsafe to keep the car at a constant speed.
fObserve all local and national speed limits. Switch automatic speed control readiness
