Camera and radar sensor's field of vision
The camera and radar sensor have limited fieldsof vision. In some situations they may detect avehicle, large animal, pedestrian or cyclist laterthan expected or not detect them at all.
Other vehicles that are dirty may be detectedlater than others and in dark conditions, motorcy-cles may be detected late or not at all.
If a text message is displayed in the instrumentpanel indicates that the camera or radar sensorare blocked, it may be difficult for City Safety todetect a vehicle, pedestrian or cyclist and thesystem's functionality may be reduced.

WARNING
Text messages may not be displayed in all sit-uations in which the camera and/or radarsensor are blocked. It is therefore essential tokeep the windshield in front the camera/radarsensor clean and free from snow, ice, etc.
Camera and radar sensor components shouldonly be serviced or replaced by a trained andqualified Volvo service technician.

Action by the driver
Backing up
City Safety is temporarily deactivated while thevehicle is backing up.

Low speed
City Safety is not activated at very low speeds(under approx. 3 mph (4 km/h). This means that
the system will not be triggered if your vehicleapproaches a vehicle ahead at very low speed,such as when parking.
Active driver
Action by the driver always has priority. For thisreason, City Safety may not react or react laterthan expected in situations in which the driver isactively operating the vehicle, even if a collision isimminent. This is also done to help eliminateexcessive warnings.

Other limitations
City Safety uses the vehicle's camera and radarsensor, which have certain general limitations.See the articles "Camera limitations" and "Radarsensor limitations" for additional information.
WARNING
•Warnings and braking may be delayed ornot occur at all if traffic, weather or otherconditions prevent the camera and/orradar sensor from detecting pedestrians,cyclists, large animals or other vehiclescorrectly.
•Other vehicles can only be detected indarkness if their headlights and taillightsare clearly visible.
•The sensors have a limited range forpedestrians and cyclists. The systemfunctions best at relative speeds up to30 mph (50 km/h). For stationary orslow-moving vehicles, the system func-tions best at speeds up to approx.43 mph (70 km/h).
•If there is a risk of colliding with a largeanimal, City Safety can reduce the vehi-cle's speed by up to 9 mph (15 km/h).Warnings and braking are most effectiveat speeds above 43 mph (70 km/h) andless effective at lower speeds.

WARNING
•Warnings for stationary or slow-movingvehicles and large animals may be impe-ded by darkness or poor visibility.
•Warnings and braking for pedestrians andcyclists will not be provided at speedsabove approx. 43 mph (70 km/h).

•Do not place, attach or mount any objectson the inside or outside of the windshieldnear or over the sensor. This could affectthe camera-based functions.
•Objects, snow, ice or dirt in the camera'sfield of vision may result in certain func-tions being reduced or disabled, or theymay respond incorrectly.

Blind Spot Information (BLIS)*limitations
Blind Spot Information functionality may bereduced in certain situations.
•Dirt, ice and snow on the sensors mayreduce functionality and prevent the systemfrom providing warnings.
•Do not attach any objects, tape, decals, etc.,on the surface of the sensors.
•BLIS is deactivated if a trailer is attached tothe vehicle's electrical system.

Maintenance
The BLIS/CTA6 sensors are located on theinside of the rear fenders/bumper.
Keep the highlighted area clean (on both sides of thevehicle)
For the system to function optimally, the areaover and around the sensors must be kept clean.
CAUTION
Repairs to the BLIS/CTA systems and/orrepainting the rear bumper should only bedone by a trained and qualified Volvo servicetechnician.

•Blind Spot Information (BLIS)* (p. 339)
•Cross Traffic Alert (CTA)* (p. 341)
Cross Traffic Alert (CTA)*
Cross Traffic Alert (CTA) is a supplementary partof Blind Spot Information and is intended todetect vehicles crossing behind your vehiclewhile you are backing up.
When does Cross Traffic Alert function
Principle for CTA
CTA supplements BLIS by warning the driver ofcrossing traffic behind your vehicle, for example,when backing out of a parking space.
It is primarily designed to detect another vehiclebut in certain cases may also detect pedestriansor smaller objects such as bicycles.
CTA is only activated when the vehicle is rollingrearward or backing up and is activated automati-cally when the gear selector is put in reverse.

Cross Traffic Alert (CTA)* limitations
CTA functionality may be reduced in certain sit-uations.

Limitations
CTA has limitations in certain situations, forexample, 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 oneside
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 mayreduce 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.

Maintenance
The CTA sensors are located on the inside of therear fenders/bumper.
Keep the highlighted area clean (on both sides of thevehicle)
For the system to function optimally, the areaover and around the sensors must be kept clean.
Do not attach any objects, tape, decals, etc., onthe surface of the sensors.
CAUTION
Repairs to the BLIS/CTA systems and/orrepainting the rear bumper should only bedone by a trained and qualified Volvo servicetechnician.

Cross Traffic Alert (CTA)* symbolsand messages
In situations where Blind Spot Informationand/or Cross Traffic Alert are not functioning
properly or if the function is interrupted, a sym-bol and a text message may be displayed in theinstrument panel. Follow the instructions provi-ded.
The following table lists several symbols and messages:

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.
