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.

interior briefly with the windows open.
Notes on operation
Depending on the outside temperature and humid-
ity, condensation can drip from the evaporator
and form a pool under the car.
This is normal and not a sign of leakage.
If uncooled air flows out when the lowest temper-
ature has been set (“LO”), switch off the air-condi-
tioning compressor and have the fault remedied at
an authorized Porsche dealer.
