Run-off Mitigation
Run-off Mitigation is designed to assist thedriver by helping return the vehicle to its trafficlane if it is about to go off the road.
Run-off Mitigation is active at speeds between
40–87 mph (65–140 km/h)10 on roads withclearly marked edges or side marker lines.
Run-off Mitigation uses a camera to monitor theedges of a road and its side marker lines. If thevehicle is about to cross the edge of the road orside marker line, Run-off Mitigation will attemptto actively steer the vehicle back onto the road. Ifthe attempt to steer the vehicle is not sufficient,the brakes will also be applied.
Run-off Mitigation does not provide steering orbraking assistance if a turn signal is being used.If the function detects that the vehicle is beingdriven actively, Run-off Mitigation activation maybe delayed for a short time.
The function has two activation levels:
•Steering assistance only
•Steering assistance and braking
Run-off Mitigation with steering assistance
only
Run-off Mitigation provides steering assistance

Park Assist*
The Park Assist system is designed to assist youwhen 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 tonethat 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 youare within approximately 1 ft (30 cm) of an objectand the highlighted sensor field is filled in.
While an audible signal is being given, its volumelevel can be raised/lowered using the >II controlin the center console or can be adjusted in thecenter displays Top view under Settings.
NOTE
Audible alerts will only be provided for objectsthat are directly in the vehicle's path.
WARNING
Park Assist is an information system, NOT asafety 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.
Rear park assist
The system's rear sensors are activated automat-ically when the engine is started and are active ifthe vehicle rolls rearward with the gear selectorin N or if R has been selected.
The distance monitored behind the vehicle isapproximately 5 ft (1.5 m). The audible signalcomes from the rear speakers.
The rear sensors will be deactivated automaticallywhen 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.
