Emission ControlThe emission control system detects malfunctions
early that could, for example, cause increased pol-
lutant emissions or consequential damage.
Faults are indicated by the warning light in the in-
strument panel by being continuously lit or flash-
ing.
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 lamp check
and goes out approx. 4 seconds after the engine
starts.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.
The warning light in the instrument panel is lit
continuously after the critical range is left.
fIn order to avoid consequential damage to the
engine or emission control system (e.g. cata-
lytic converter) go immediately to the nearest
authorized Porsche dealer to have the fault
diagnosed and rectified.
Caution!
Risk of damage. If the warning light in the in-
strument panel continues flashing even when
you have eased off the accelerator pedal,
the emission control system may overheat.

Make sure that combustible materials, such as
dry grass or leaves, cannot come into contact
with the hot exhaust system.
fSwitch off the engine.
