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.

Windshield Wiper/Washer Stalk
Caution!
Danger of injury when the windshield wipers
operate unintentionally.
Risk of damage to the engine compartment
lid, windshield and wiper system.
fOnly wipe the windshield when sufficiently wet,
otherwise it could be scratched.
fLoosen frozen wiper blades before driving off.
fDo not operate headlight washer when it is
frozen.
fAlways switch off windshield wipers in car
wash to prevent them wiping unintentionally
(rain sensor operation).
fDo not operate headlight washer in car wash-
es.
fAlways switch off windshield wipers before
cleaning the windshield to avoid unintentional
operation (rain sensor operation).
fAlways hold the wiper arm securely when re-
placing the wiper blade.fAlways switch the windscreen wipers off (posi-
tion 0) before opening the engine compart-
ment lid. If the wiper arms are not in position
0, they will automatically move to this position
when the engine compartment lid is opened.
This will happen even if the ignition is off.
The wiper arms remain in this position until the
lid is closed and the wiper system is switched
off and then on again.
0 – Windshield wipers off
1 – Front windshield wiper – rain sensor op-
eration
fMove wiper stalk upwards to the first click.
Notes on operation
The amount of rain or snow which has settled on
the windshield is measured. Wiper speed is auto-
matically adjusted accordingly.

Controls, Safety, Instruments The rain sensor remains switched off if the wiper
lever is already in position 1 when the ignition is
switched on.
To switch the rain sensor on again:
fMove wiper stalk to position 0 and then to
position1 – switching on is confirmed by one
wipe of the windscreen – or
fOperate windscreen washer system 5–
switching on is confirmed by three wipes of the
windscreen – or
fChange the sensitivity of the rain sensor with
four-stage switch A.Changing the sensitivity of the rain sensor
Sensitivity can be set with switch A in 4 stages:
fAdjust switch A upwards –
high sensitivity.
The setting is confirmed by one wipe of the
windshield.
fAdjust switch A downwards –
low sensitivity.
2 – Front windshield wiper – slow
fMove wiper stalk upwards to the second click.
3 – Front windshield wiper – fast
fMove wiper stalk upwards to the third click.
At speeds of less than approx. ca. 2.5 mph
(4 km/h), rain sensor operation mode is automat-
ically activated if the windshield wiper is switched
on. If you exceed a speed of approx. 5 mph
(8 km/h), the system switches to the pre-selected
wiper level.
4 – Front windshield wiper – one-touch oper-
ation
fMove wiper stalk downwards. The front wind-
shield wipers go through one wipe cycle.5 – Front windshield wipers and washer sys-
tem
fPull wiper stalk towards the steering wheel.
The washer system sprays and wipes while the
lever is pulled towards the steering wheel.
When the wiper lever is released, a few drying
wipes are executed.
Headlight washer (on vehicles with Bi-Xe-
non headlights):
The washer sprays only while low beam or high
beam is switched on.
To activate the headlight washer system, the
wiper lever must be pulled for a longer period
of time.
The spray duration is limited.
Maintenance note
fIf heavily soiled, repeat wash.
fPersistent dirt (e.g. insect remains) should be
regularly removed.
Please observe the chapter “CAR CARE IN-
STRUCTIONS” on Page 265.
Thefront windscreen washer nozzles are heat-
ed when the ignition is on, as a precaution against
freezing.

Front ultrasound sensorsSensors
Six ultrasound sensors in the front and rear
bumpers measure the distance to the closest ob-
stacle.
– Range of outer sensors
(front and rear):
approx. 24 in. (60 cm)
– Range of front middle sensors (arrow):
approx. 48 in. (120 cm)
Rear ultrasound sensors– Range of rear middle sensors (arrow)
(only in vehicles without spare wheel bracket):
approx. 59 in. (150 cm)
– Range of rear middle sensors
(only in vehicles with spare wheel bracket):
approx. 48 in. (120 cm)
Obstacles cannot be detected in the "blind" sensor
area (above and below the sensors).Maintenance note
fThe sensors must always be kept free of dust,
ice and snow in order to ensure that they are
fully functional.
fDo not damage sensors by abrasion or
scratching.
fMaintain sufficient distance when cleaning with
steam-jet units.
The sensors will be damaged if the pressure is
too high.
Note on operation
The rear ultrasound sensors may not function
correctly if tires that have not been recommended
by Porsche are fitted on the spare wheel bracket.
If the spare wheel bracket is open, this may impair
the function of the rear ultrasound sensors.
In vehicles that have air suspension with level
control and height adjustment, the system may
not recognise obstacles near the ground at terrain
level or special terrain level.

A- Front display – left monitoring area
B- Front display – right monitoring areaWarning indicators, signal tones, distances
The warning indicator for the front area is located
on the dashboard.
The warning indicator for the rear area is located
in the rooflining at the rear of the loadspace.
The warning indicators for the various monitoring
areas (left and right) are subdivided respectively
into one green, 4 yellow and 2 red light segments.
C- Rear display – right monitoring area
D- Rear display – left monitoring areaIf ParkAssist is activated, the green light seg-
ments of the active warning indicators are lit up
continuously.
If the vehicle approaches an obstacle that has
been detected by the sensors, one or more of the
yellow or red light segments lights up, depending
on the distance to the obstacle.If the first yellow light segment lights up, the ob-
stacle is still 48 in. (120 cm) (to the front) or 48 in.
to 59 in. (120 to 150 cm) (to the rear) away.
A brief signal tone sounds when reversing.
Anintermittent tone sounds when the distance
becomes less than approx. 24 in. (60 cm). The
fourth yellow light segment lights up.
Acontinuous tone sounds when the distance be-
comes less than approx. 10 in. (25 cm) (on vehi-
cles with trailer coupling: approx. 14 in. (35 cm)).
Thesecond red light segment lights up.
If the obstacle is approached even closer, the sys-
tem may not be able to recognize the obstacle any
longer.
fSet the radio volume so that the signal tones
are not drowned out.
You can have the volume of the signal tones ad-
justed to your own requirements at your autho-
rized Porsche dealer.
Note on operation
If the obstacle is approached even closer after the
continuous tone sounds and the second red light
segment lights up, the system may not be able to
recognize the obstacle any longer.
