ParkAssist
ParkAssist provides a visual and audible indication
to the driver of the distance between the vehicle
and an obstacle.
ParkAssist is switched on automatically when the
ignition is switched on and remains active up to a
speed of approx. 14 km/h (9 mph).
ParkAssist is switched off automatically at higher
speeds. ParkAssist is switched on again automat-
ically when the speed drops below approx.
14 km/h (9 mph).
ParkAssist is activated together with the corre-
sponding monitoring range depending on the
position of the Tiptronic selector lever or gearshift
lever.
– ParkAssist is activated automatically when
reverse gear is selected and the ignition is on.
Tiptronic selector lever position:
– P – ParkAssist is not activated.
– R, N – ParkAssist is activated for the front and
rear areas.
– D, M – ParkAssist is activated for the front
area.
Gearshift lever position:
– R – ParkAssist is activated for the front and
rear areas.
– in all other gearshift positions – ParkAssist
is activated for the front area.
Note
On vehicles with manual transmission, ParkAssist
is not switched on in the rear area if the vehicle
rolls backward without reverse gear engaged.
Warning!
Risk of accident. Even when using
ParkAssist, the driver is still responsible for
taking appropriate care when parking and
when assessing obstacles.
f Make sure that no persons, animals or obsta-
cles are within the manoeuvring area.
Switching ParkAssist on and off
f Switch ParkAssist on and off using button A in
the roof console.
When ParkAssist is switched off, the indicator
light in the button lights up.
Note on operation
It is recommended to switch off ParkAssist when
driving on unpaved surfaces and off-road.
Parking 255
Front ultrasound sensors
Sensors
Six ultrasound sensors in the front and rear
bumpers measure the distance to the closest
obstacle.
– Range of outer sensors
(front and rear):
approx. 60 cm
– Range of front middle sensors (arrow):
approx. 120 cm
Rear ultrasound sensors
– Range of rear middle sensors (arrow)
(on vehicles without spare wheel bracket):
approx. 150 cm
– Range of rear middle sensors
(on vehicles with spare wheel bracket):
approx. 120 cm
Obstacles cannot be detected in the “blind”
sensor area (above and below the sensors).
Maintenance notes
f The sensors must always be kept free of dust,
ice and snow in order to ensure that they are
fully functional.
f Do not damage sensors by abrasion or
scratching.
f Maintain 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 tyres that have not been recom-
mended 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.
On 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 area
Warning 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 roof lining at the rear of the vehicle.
The warning indicators for the respective
monitoring areas (left and right) are subdivided
into one green, 4 yellow and 2 red LED segments.
C - Rear display – right monitoring area
D - Rear display – left monitoring area
If ParkAssist is activated, the green LED
segments 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 LED segments lights up, depending
on the distance to the obstacle.
If the first yellow LED segment lights up, the
obstacle is still 120 cm (front) or 120 to 150 cm
(rear) away.
A brief signal tone sounds when reversing.
An intermittent tone sounds when the distance
becomes less than approx. 60 cm. The fourth
yellow LED segment lights up.
If the distance becomes less than approx. 25 cm
(on vehicles with trailer coupling: approx. 35 cm),
a continuous tone sounds. The second red LED
segment lights up.
f Set the radio volume so that the signal tones
are not drowned out.
You can have the volume of the signal tones
adjusted to your own requirements.
f Consult a qualified specialist workshop. We
recommend that you use a Porsche partner for
this work since these are staffed with trained
personnel and have the necessary parts and
tools.
Note on operation
If the obstacle is approached even closer after the
continuous tone sounds and the second red LED
segment lights up, the system may not be able to
recognise the obstacle any longer.
Parking 257
Limits of ultrasonic measurement
– ParkAssist cannot detect sound-absorbing
obstacles (e.g. powdery snow),
– sound-reflecting obstacles (e.g. glass
surfaces, flat painted surfaces),
– and very thin obstacles.
Other sources of ultrasound (e.g. pneumatic
brakes of other vehicles and jackhammers) may
interfere with detection of obstacles.
Fault indication without warning tone
All red LED segments of the active warning indica-
tors light up when there is a temporary fault in
ParkAssist as a result of other ultrasound sources.
Note
Correct operation is no longer guaranteed if there
is a temporary fault (e.g. caused by ice formation
or heavy soiling on the sensors).
The system detects the temporary fault. All LED
segments light up until a speed of 14 km/h
(9 mph) is reached.
ParkAssist is ready for operation again when the
interference is no longer present.
Fault indication with warning tone
In the event of a permanent fault in ParkAssist,
the red LED segments of the active warning indica-
tors light up and a continuous tone sounds for
three seconds after a transmission range has
been selected.
Possible causes
– Defect or system fault.
f Switch ParkAssist off.
When ParkAssist is switched off, the indicator
light in the button lights up.
Please observe the chapter “SWITCHING
PARKASSIST ON AND OFF” on Page 254.
f Have the fault remedied. Consult a qualified
specialist workshop. We recommend that you
use a Porsche partner for this work since
these are staffed with trained personnel and
have the necessary parts and tools.
Driving with a trailer
The ParkAssist rear monitoring area is switched
off when the trailer’s power supply is plugged in.
