Level gage

When the ignition is on the fuel level is displayed.
f Please see 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 a small quantity of fuel
is added to a nearly emp-
ty fuel tank, the fuel ga ge cannot measure the add-
ed fuel accurately. The „remaining range“ readout
will also be incorrect.
Warning light “A” When the engine is running, the warning light
of the level gage lights up if less than approx.
2.6 U.S. gallons (10 liters) of fuel remains in the
tank.
Additionally, a warning is displayed in the on-board
computer.
f Fill up at the next opportunity.
Caution!
To prevent damage to the emission control
system and engine.
f Never drive the tank completely out of fuel.
f Avoid high cornering speeds after the warning lights have come on.
f Please see the chapter “EMISSION CONTROL
SYSTEM” on Page 198. If the level gage 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.
f To remedy the fault, go to an authorized
Porsche dealer.

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.
f In 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.
f Stop 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.
f Have the fault remedied at the nearest authorized Porsche dealer immediately.

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
refueling, 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.
