Recommended Park Assist Pilot Maintenance - Volvo XC90 Owner's Manual

IMPORTANT
Objects e.g. chains, thin glossy poles or low
barriers may be in the "signal shadow" and
are then temporarily not detected by the sen-
sors - the pulsating tone may then unexpect-
edly stop instead of changing over to the
expected constant tone.
The sensors cannot detect high objects, such
as projecting loading docks.
•
In such situations, pay extra attention and
manoeuvre/reposition the car particularly
slowly or stop the current parking
manoeuvre - there may be a high risk of
damage to vehicles or other objects since
information from the sensors is not
always reliable in such situations.
IMPORTANT
In certain conditions the parking assistance
system may produce incorrect warning sig-
nals that are caused by external sound
sources with the same ultrasonic frequencies
that the system works with.
Examples of such sources include horns, wet
tyres on asphalt, pneumatic brakes, exhaust
noises from motorcycles, etc.
NOTE: The illustration is schematic - details may vary depending on car model.

NOTE
Since a towbar is configured with the car's
electrical system, towbar protrusion is
included when the function measures the dis-
tance to an object behind the car.
