Cross Traffic Alert (CTA) * limitations
CTA functionality may be reduced in certain sit- uations.
LimitationsCTA has limitations in certain situations, for example, the CTA sensors cannot "see" throughother parked vehicles or obstructions. The following are several examples where CTA's "field of vision" may initially be limited andapproaching vehicles cannot be detected untilthey are too close:
The vehicle is pulled far into a parking space
In angled parking spaces, CTA may be "blind" on one side
CTA's blind area
CTA's "field of vision"
However, as you back your vehicle out of a park- ing space, CTA's "field of vision" expands. Examples of other limitations include:
• Dirt, ice or snow obstructing the sensors may reduce the system's function or make itimpossible to detect other vehicles orobjects.
• CTA is deactivated if a trailer's wiring is con-nected to the vehicle's electrical system.
MaintenanceThe CTA sensors are located on the inside of therear fenders/bumper.

Road Sign Information (RSI) *
limitations
The RSI function may be limited in certain situa- tions.
RSI may have difficulty reading signs that are:
• Faded
• Located in a curve
• Twisted or damaged
• Positioned high above the road
• Obstructed (by bushes, etc.)
• Partially covered by snow, ice, etc.
• If the digital maps used by the Sensus Navigation system
* are not up-to-date or do
not contain speed information 6
.
The camera used by RSI has certain limitations. See the article "Camera limitations" for additionalinformation.
NOTE
RSI may perceive certain types of bicycle holders (with wiring attached to the trailerelectrical socket) as a trailer, which may resultin faulty speed limit information to the driver.

Driver Alert Control (DAC)
DAC is intended to alert the driver if his/her driv- ing becomes erratic due to e.g., distraction orfatigue.
DAC is designed to help detect a slowly chang- ing driving pattern. It is primarily intended to be used on main roads and is not meant for use incity traffic. The function activates initially when the vehicle's speed first exceeds 40 mph (65 km/h) andremains active as long the speed remains aboveapprox. 37 mph (60 km/h)
A camera monitors the traffic lane's side marker lines and compares the direction of the road withthe driver

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.
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 selector in N or if R has been selected.
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.

Park Assist limitations
The Park Assist system has certain limitations.
NOTE
A trailer hitch whose wiring is integrated with the vehicle's electrical system will be takeninto account when measuring the availablespace behind the vehicle.
NOTE
• The system will not detect high objects, such as a loading dock, etc.
• Certain materials or fabrics may not bedetected by the sensors. Objects made ofthese materials or people wearing cloth-ing made of these fabrics may not bedetected.
• Children or animals near the vehicle maynot always be detected.
• Objects such as chains, thin shiny polesor low objects may temporarily not bedetected by the system. This may resultin the pulsing tone unexpectedly stoppinginstead of changing to a constant tone asthe vehicle approaches the object. Insuch cases, use caution when backing upor stop the vehicle to help avoid damage.
• In certain circumstances, the park assistsystem may give unexpected warning sig-nals that can be caused by externalsound sources that use the same ultra-sound frequencies as the system. Thismay include such things as the horns ofother vehicles, wet tires on asphalt, pneu-matic brakes, motorcycle exhaust pipes,other vehicles with similar ultrasound sys-tems, etc. This does not indicate a fault inthe system.
Cleaning the sensors
Location of the Park Assist sensors
The sensors must be cleaned regularly to ensure that they work properly. Clean them with waterand a suitable car washing detergent.
NOTE
If the sensors are obstructed by e.g., dirt, snow, or ice, this could result in false warningsignals from the park assist system or thesystem may not function at all.

Backing up
Location of the rear Park Assist Camera (generic illus- tration)
The rear camera shows a wide area behind the vehicle and on certain models, part of the bumperand the trailer hitch (if installed) will be visible. Some objects on the screen may appear to “lean” slightly, which is normal.
WARNING
People/objects/obstructions displayed on the center console screen may be closer to thevehicle than they appear.
Front camera
Location of the front Park Assist Camera (generic illus- tration)
The front camera is located behind the grill and can be useful when driving off in areas with lim-ited visibility (hedges, bushes, etc). It is active atspeeds up to approx. 16 mph (25 km/h) and isautomatically turned off when the vehicleexceeds this speed. However, if the vehicle's speed does not exceed 30 mph (50 km/h) and its speed goes under14 mph (22 km/h) within 60 seconds after thecamera has been switched off, the front camerawill reactivate.
NOTE
The front camera will only reactivate automati- cally if Auto Camera Reverse Activation
has been selected in SettingsMy CarPark Assist.
Side camera
The side cameras are located in the respective door mirrors and show views along the sides ofthe vehicle.

trajectory lines and fields
The Park Assist Camera system uses trajectory lines and fields to indicate the vehicle's positionin relation to its immediate surroundings.
Trajectory lines
Sample guidelines
The trajectory lines are intended to show the position of the vehicle's outermost dimensionsbased on the current position of the steeringwheel to help simplify parallel parking, backinginto tight spaces or when attaching a trailer. The lines on the screen are projected as if they were a path on the ground around the vehicleand are directly affected by the way in which thesteering wheel is turned. This enables the driverto see path the vehicle will take, even if he/sheturns the steering wheel. These lines also indicate the outermost limits thatany object (door mirrors, corners of the body, atrailer hitch, etc.) extends out from the vehicle,even when it turns.
NOTE
When backing up with a trailer, the trajectory lines show the path that the
vehicle will take,
not the trailer. Trajectory lines will not be displayed while zooming in.
WARNING
Keep in mind that when the rear camera has been selected, the image on the screen onlyshows the area behind the vehicle. The drivermust always watch for people, animals, othervehicles, etc., near the sides or the front of thevehicle when turning while backing up. The opposite is true when the front camera is selected. Please note that the trajectory lines show the shortest path. Be sure that the vehicle
