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. 14 in.
(35 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 150.
Warning!
Risk of accidents. Even when using
ParkAssist, the driver is still responsible for
taking due care when parking and when
assessing obstacles.
f
Do not reverse any further once a continuous
tone sounds.
Risk of collision!
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.
