NOTE
•
Front park assist is disengaged auto-
matically when the parking brake is
applied.
•
If the vehicle is equipped with front
and rear park assist, both systems will
be deactivated by pressing the button.
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 in front of or behind the vehicle. If the
volume of another source from the audio sys-
tem is high, this will be automatically lowered.
If there are objects within this distance both
behind and in front of the vehicle, the signal
alternates between front and rear speakers.
Faults in the system
If the yellow warning symbol illu-
minates and PARK ASSIST
SERVICE REQUIRED
on the information display, this
indicates that the system is not
functioning properly and has been disen-
gaged. Consult a trained and qualified 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.

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.

If the sensors are obstructed by e.g., dirt,
snow, or ice, this could result in false
warning signals from the park assist sys-
tem.
