City Safety and delayed evasivemaneuvers
City Safety can assist the driver by automaticallybraking the vehicle when it is not possible toavoid a collision by steering alone.
City Safety assists the driver by periodicallyattempting to predict possible "escape routes" tothe sides of the vehicle in the event a slow-mov-ing or stationary vehicle were to be detected at alate stage.
Your vehicle (1) cannot detect any potential escaperoutes for veering away from the vehicle ahead (2) andmay therefore apply the brakes at an earlier stage.
Own vehicle
Slow-moving/stationary vehicles
City Safety will not intervene to automaticallyapply the brakes if it is possible for the driver toavoid a collision by steering the vehicle.
However, if City Safety determines that an eva-sive maneuver would not be possible due to traf-fic in the adjacent lane(s), the function can assistthe driver by automatically starting to apply thebrakes at an earlier stage.

WARNING
The possibility of City Safety predicting acertain situation is supplementary driversupport intended to improve driving safety– it cannot handle all situations in all traf-fic, weather and road conditions.
City Safety is not a substitute for the driv-er's attention and judgment. The driver isalways responsible for ensuring the vehi-cle is driven in a safe manner, at theappropriate speed, with an appropriatedistance to other vehicles, and in accord-ance with current traffic rules and regula-tions.

Limitations of City Safety during evasive
maneuvers
NOTE
The function uses the vehicle's combinedcamera and radar unit, which has certain gen-eral limitations; see sections "Camera limita-tions" and "Radar sensor limitations".

City Safety braking for oncomingvehicles
City Safety can help you apply the brakes for anoncoming vehicle in your lane.
If an oncoming vehicle veers into your lane and acollision is unavoidable, City Safety can helpreduce your vehicle's speed to attempt to miti-gate the force of the collision.
Own vehicle
Oncoming vehicles
The following criteria must be met for the func-tion to work:
your vehicle's speed must be above 4 km/h(3 mph)
the road must be straight
your lane must have clear side lane markings
your vehicle must be positioned straight inyour lane
the oncoming vehicle must be positionedwithin your vehicle's lane markings
the oncoming vehicle's headlights must beon
the function can only handle “front-to-front”collisions
the function can only detect vehicles withfour wheels
the function requires functioning ElectricSeat Belt Tensioners (see section “Seatbelt tensioners”).

NOTE
The function uses the vehicle's combinedcamera and radar unit, which has certain gen-eral limitations; see sections "Camera limita-tions" and "Radar sensor limitations".
WARNING
The "City Safety braking for oncomingvehicles" function is supplementary driversupport intended to help improve drivingsafety – it cannot handle all situations inall traffic, weather and road conditions.
Warnings and brake interventions due toan imminent collision with an oncomingvehicle always come very late.
Never wait for a collision warning or forCity Safety to intervene. If you notice anyhazard or other potentially dangerous sit-uation, always fully apply the brakes.
City Safety is not a substitute for the driv-er's attention and judgment. The driver isalways responsible for ensuring the vehi-cle is driven in a safe manner, at theappropriate speed, with an appropriatedistance to other vehicles, and in accord-ance with current traffic rules and regula-tions.

City Safety limitations
City Safety functionality may be reduced in cer-tain situations.

Surroundings
Low objects
Hanging objects, such as flags for overhangingloads or accessories such as auxiliary lights orfront protective grids that extend beyond theheight of the hood, may limit City Safety function-ality.

Slippery road conditions
The extended braking distance on slippery roadsmay reduce City Safety's capacity to help avoid acollision. In these types of situations, the Anti-lock Braking System and Electronic Stability Con-
trol (ESC68) will help provide optimal brakingpower with maintained stability.

Backlighting
The visual warning signal in the windshield maybe difficult to detect in bright sunlight, if there arereflections, or if the driver is wearing sunglassesor not looking straight ahead.

Heat
If the temperature in the passenger compartmentis high due to e.g. bright sunlight, the visual warn-ing signal in the windshield may be temporarilydisabled.
Camera and radar sensor's field of vision
The camera's field of vision is limited and in cer-tain situations, it may be unable to detect pedes-trians, large animals, cyclists or vehicles, or it maydetect them later than expected.
Vehicles that are dirty may be detected later thanclean vehicles, and in dark conditions, motorcy-cles may be detected late or not at all.
If a text message displayed in the instrumentpanel indicates that the camera/radar sensor isobstructed, it may be difficult for City Safety todetect pedestrians, large animals, cyclists, vehi-cles or lane markings in front of the vehicle. CitySafety functionality may therefore be reduced.
Text messages may not be displayed for all situa-tions in which the windshield sensors areblocked. The driver must therefore always keepthe windshield in front of the camera/radar sen-sor clean.

CAUTION
Maintenance and replacement of City Safetycomponents may only be performed by aworkshop – an authorized Volvo workshop isrecommended.
Driver intervention
Backing up
City Safety is temporarily deactivated when thevehicle is backing up.

Low speed
City Safety is not activated at very low speedsunder 4 km/h (3 mph). The system will thereforenot intervene in situations in which your vehicle isapproaching another vehicle very slowly, such aswhen parking.

Active driver
Action by the driver always has priority. CitySafety will therefore not react or will react at alater stage with a warning or intervention in situa-tions in which the driver is clearly steering andoperating the accelerator pedal, even if a collisionis unavoidable.
An active and aware driving style may thereforedelay collision warnings and intervention in orderto minimize unnecessary warnings.

Other limitations
WARNING
Warnings and brake interventions can betriggered late or not at all if the traffic sit-uation or external influences prevent thecamera and radar unit from properlydetecting pedestrians, cyclists, large ani-mals or vehicles ahead of the vehicle.
To be able to detect vehicles at night, itsfront and rear lights must work and illumi-nate clearly.
The camera and radar unit have a limitedrange for pedestrians and cyclists – thesystem can provide effective warningsand brake interventions if the relativespeed is lower than 50 km/h (30 mph).For stationary or slow-moving vehicles,warnings and brake interventions areeffective at vehicle speeds of up to70 km/h (43 mph). Speed reduction forlarge animals is less than 15 km/h(9 mph) and can be achieved at vehiclespeeds over 70 km/h (43 mph). At lowerspeeds, the warning and brake interven-tion for large animals is less effective.
Warnings for stationary or slow-movingvehicles and large animals can be disen-gaged due to darkness or poor visibility.
Warnings and brake interventions forpedestrians and cyclists are disengagedat vehicle speeds over 80 km/h(50 mph).
Do not place, affix or mount anything onthe inside or outside of the windshield, orin front of or around the camera andradar unit – this could disrupt camera-based functions.
Objects, snow, ice or dirt in the area ofthe camera sensor can reduce the func-tion, disengage it completely or give animproper function response.

NOTE
The function uses the vehicle's combinedcamera and radar unit, which has certain gen-eral limitations; see sections "Camera limita-tions" and "Radar sensor limitations".

Cross Traffic Alert*
CTA77 is a supplementary driver support system
to BLIS78 that is intended to help the driverdetect vehicles crossing behind the vehiclewhile backing up.
CTA overview.
CTA supplements BLIS by detecting traffic cross-ing from the side, e.g. when backing out of aparking space.
CTA is primarily designed to detect vehicles, butin certain cases can also detect pedestrians orsmaller objects such as bicycles.
CTA is only active when the vehicle is movingbackward or if reverse gear is engaged.
If CTA detects that something is approachingyour vehicle from the side:
an audible signal will sound from either theleft or right speaker, depending on whichside of your vehicle the object is approachingfrom.
an icon will illuminate in the PAS79 graphicon the screen.
an icon will appear in the Park Assist Cam-era's Top view.
Illuminated CTA icon in the PAS graphic80 on thescreen.

WARNING
The Cross Traffic Alert function is supple-mentary driver support intended to facili-tate driving and make it safer – it cannothandle all situations in all traffic, weatherand road conditions.
The responsibility for reversing the vehiclesafely and using good judgment alwaysrests with the driver.
Cross Traffic Alert is not a substitute forthe driver's attention and judgment. Thedriver is always responsible for ensuringthe vehicle is driven in a safe manner, atthe appropriate speed, with an appropri-ate distance to other vehicles, and inaccordance with current traffic rules andregulations.
