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.
fStop as soon as possible in a safe place.
Make sure that combustible materials, such as
dry grass or leaves, cannot come into contact
with the hot exhaust system.
fSwitch off the engine.
fContact your nearest authorized Porsche deal-er to have the fault rectified.

Automatic driving light assistantThe driving light assistant is a comfort function.
Your Porsche’s driving light (low beam) is switched
on and off automatically, irrespective of the ambi-
ent brightness.
Despite possible support by the driving light assis-
tant, it is the responsibility of the driver to switch
on the driving light using the conventional light
switch in accordance with the relevant national
regulations.
Activating the headlights using the driving light as-
sistant does not therefore absolve the driver
of responsibility for the correct operation of the
driving light.
The low beam is switched on automatically in the
following situations:
–Dusk
–Darkness
– Travelling through tunnels
– Rain (in conjunction with the rain sensor)
– Highway driving
Note on operation
Fog is not recognised.
fIn the event of fog, the driving light must be
switched on manually.
Warning!
Risk of accident due to driving without lights.
fAlways carefully monitor the automatic driving light control.
Highway function
The light is switched on at speeds of over 87 mph
(140 km/h). If you are travelling slower than
40 mph (65 km/h), the driving light is switched off
after a delay of approx. 2 minutes, if the external
lighting conditions permit.
Rain function
The driving light is switched on after five seconds
of continuous wiper operation.
The driving light is switched off approx. 4 minutes
after the wipers have stopped.
Bi-Xenon main headlights with
dynamically controlled cornering lightThe Bi-Xenon main headlights are equipped with
an additional light in vehicles with a cornering
light. As a result of its particular positioning, the
additional light provides significantly better lane
lighting to the left and right of the main light beam.
