Parking Aids - Porsche 911 Turbo Driver Manual

Parking Aids

ParkAssist
When the driver backs up, ParkAssist indicates the
distance between the car and an obstacle by
means of signal tones.
d
Warning!
Risk of accident. Even when using
ParkAssist, the driver is still responsible for
taking due care when parking and when
assessing obstacles.
f Make sure that no persons, animals or
obstacles are within the manoeuvring area.
ParkAssist is activated automatically when
reverse gear is selected and the ignition is on.
Note
ParkAssist is not switched on if the car rolls
backward without reverse gear engaged.
Ultrasound sensors
Sensors
Four ultrasound sensors in the rear bumper
measure the distance to the closest obstacle.
– Range of middle sensors: Approx. 150 cm
– Range of outer sensors: Approx. 60 cm
Obstacles cannot be detected within the blind
sensor area (e.g. near the ground).
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 To avoid damaging the sensors, maintain
sufficient distance when cleaning with steam-
jet units.
Signal tones/function
When reverse gear is selected, ParkAssist
confirms that it is switched on by issuing a short
signal tone.
A detected obstacle is signalled by
an intermittent tone. The intervals decrease
as the obstacle is approached.
If the distance drops to less than approx. 30 cm),
a continuous tone sounds. This continuous tone
can stop if the obstacle is approached even
closer.
f Set the radio volume so that the signal tones
are not drowned out.
Limits of ultrasonic measurement
– ParkAssist cannot detect sound-absorbing
obstacles (e.g. winter driving, powder 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.
