Parking 227
Information
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
high-pressure cleaning equipment.
The sensors will be damaged if the pressure
is too high.
Signal tones/function
When reverse gear is selected, ParkAssist
confirms that it is switched on by issuing a short
signal tone.
If the vehicle has front ParkAssist, no signal tone
will be issued when reverse gear is selected.
Instead, the ParkAssist visual display will
appear on the central screen of the Porsche
communication system.
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. 14 in.
(35 cm), a continuous tone sounds.
f Set the radio volume so that the signal tones
are not drowned out.
You can adjust the volume of the signal tones to
your own requirements.
For information on changing the signal tone
volume:
f Please see the chapter “ADJUSTING VOLUME
OF WARNING AND INFORMATION TONES” on
page 137.
Even when using ParkAssist, the driver is still
responsible for taking due care when parking and
when assessing obstacles.
A continuous tone sounds when there is a risk of
collision.
f Do not drive rearward any further once
a continuous tone sounds.
Limits of ultrasonic measurement
– ParkAssist cannot detect sound-absorbing
obstacles (e.g. winter driving, powder snow),
– sound-reflecting obstacles (such as glass
surfaces and flat painted surfaces),
– and very thin obstacles (e.g. thin posts).
Other ultrasound sources (such as the pneumatic
brakes of other vehicles and jack hammers) can
interfere with the detection of obstacles.
Deactivating ParkAssist
f Press button A on the overhead operating
console.
The indicator light on the button lights up.
ParkAssist is switched off.
Fault indication
Correct operation is no longer guaranteed if there
is a temporary fault (e.g. caused by ice formation
or heavy soiling on the sensors).
