Audible signals from the park assist
system
The Park Assist system uses an intermittent
tone that pulses faster as you come close to an
object, and becomes constant when you are
within approximately 1 ft (30 cm) of an object
behind the vehicle. If the volume of another
source from the audio system is high, this will
be automatically lowered.
Faults in the system
If the information symbol illumi-
nates and
PARK ASSIST
SERVICE REQUIRED is shown
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 technician.
CAUTION
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,
motorcycle exhaust pipes, etc. This does
not indicate a fault in the system.
Cleaning the sensors
Park assist sensors
The sensors must be cleaned regularly to
ensure that they work properly. Clean them
with water and a suitable car washing deter-
gent.
Ice and snow covering the sensors may cause
incorrect warning signals.
NOTE
If the sensors are obstructed by e.g., dirt,
snow, or ice, this could result in false warn-
ing signals from the park assist system.
