Ultrasound 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
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. 12 in.
(30 cm), a
continuous tone
sounds.
f
Set the radio volume so that the signal tones
are not drowned out.
The volume of the signal tones can be changed
individually.
For information on changing the signal tone
volume:
f
Please see the chapter “ADJUSTING
PARKASSIST VOLUME” on page 112.
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,
clothing made from fabric or fur),
– sound-reflecting obstacles (such as glass
surfaces and flat painted surfaces),
– and very thin obstacles (e.g. thin posts).
Other ultrasound sources (e.g. pneumatic brakes
of other vehicles, sweeping machines and jack
hammers) can interfere with the detection of
obstacles.
