Park Assist *
The Park Assist system is designed to assist you
when driving into parking spaces, garages, etc. An audible signal and symbols in the instrumentpanel and center display indicate the distance tothe object.
Display view showing object zones and sensor sectors
The center display shows an overview of the vehi- cle in relation to objects that have been detected. The highlighted sector shows which of the sen- sors has detected the object. The closer thehighlighted sector is to the vehicle symbol, thecloser the actual object is to your vehicle. The Park Assist system uses an intermittent tone that pulses faster as you come closer to anobject. Sound from the infotainment system willbe temporarily turned down. The audible signals for objects in front of and tothe sides are active while the vehicle is movingand will stop after the vehicle has been stoppedfor approx. 2 seconds. The audible signals forobjects behind the vehicle are active even whenthe vehicle has stopped moving. The audible signal becomes constant when you are within approximately 1 ft (30 cm) of an objectand the highlighted sensor field is filled in. While an audible signal is being given, its volume level can be raised/lowered using the
>II control
in the center console or can be adjusted in the center displays Top view under
Settings.
NOTE
Audible alerts will only be provided for objects that are directly in the vehicle's path.
WARNING
Park Assist is an information system, NOT a safety system. This system is designed to bea supplementary aid when parking the vehicle.It is not, however, intended to replace the driv-er's attention and judgement.

The distance monitored behind the vehicle is approximately 5 ft (1.5 m). The audible signalcomes from the rear speakers. The rear sensors will be deactivated automatically when towing a trailer if Volvo genuine trailer wir-ing is used. If a non-Volvo trailer hitch is beingused, it may be necessary to switch off the sys-tem manually.
