Faults in the system
If the information symbol illuminates and
Park Assist syst Service required
on the information display, this indicates that
the system is not functioning properly and
has been disengaged. Consult a Volvo
retailer or authorized Volvo service techni-
cian.
CAUTION
04
In certain circumstances, the park assist
system may give unexpected warning sig-
nals that can be caused by external sound
sources that use the same ultrasound fre-
quencies as the system. This may include
such things as the horns of other vehicles,
wet tires on asphalt, pneumatic brakes, mo-
torcycle exhaust pipes, etc. This does not
indicate a fault in the system.

Cleaning the sensors
The sensors must be cleaned regularly to
ensure that they work properly. Clean them
with water and a suitable car washing deter-
gent.
