The Late warning distance setting should there-fore only be used in exceptional cases, such aswhen a more dynamic driving style is preferred.

WARNING
No automatic system can guarantee100% correct function in all situations.You should therefore never test use ofCity Safety in the direction of people, ani-mals or vehicles – this could lead tosevere damage, serious personal injury oreven death.
City Safety warns the driver if there is arisk of collision, but the function cannotreduce the driver's reaction time.
Even if the warning distance has been setto Early, warnings may be perceived aslate in certain situations – e.g. when thereare large speed differences or if the vehi-cle ahead suddenly brakes heavily.
With the warning distance set to Early,warnings come further in advance. Thismay cause the warnings to come morefrequently than with warning distanceNormal, but is recommended since it canmake City Safety more effective.
NOTE
The warning with direction indicators for RearCollision Warning is deactivated if the colli-sion warning distance in the City Safety func-tion is set to the lowest level "Late".
The seat belt tensioning and braking func-tions remain active.

Detecting obstacles with City Safety
City Safety can help detect vehicles, cyclists,large animals and pedestrians.
Vehicles
City Safety detects most types of vehicles thatare either stationary, moving in the same direc-tion as your vehicle or those described in “CitySafety in crossing traffic” and City Safety brakingfor oncoming vehicles”.
For City Safety to be able to detect a vehicle inthe dark, its headlights and taillights must be onand clearly visible.

Cyclists
Optimal examples of what City Safety would interpret tobe a cyclist: clear body and bicycle shapes.
For optimal performance, the system's functionfor cyclist detection needs the clearest possibleinformation about the contours of the bicycle and

of the cyclist's head, arm, shoulders, legs, torsoand lower body in combination with normalhuman movements.
If large portions of the cyclist's body or the bicy-cle itself are not visible to the function's camera,it will not be able to detect a cyclist.
The system can only detect adult cyclists ridingon bicycles intended for adults.

WARNING
City Safety is supplementary driver support,but it cannot detect all cyclists in all situationsand, for example, cannot see:
partially obscured cyclists.
cyclists if the background contrast of thecyclist is poor - warning and brake inter-ventions may then be late or not occur atall.
cyclists in clothing that hides their bodycontour.
bikes loaded with large objects.
The driver is always responsible for ensuringthat the vehicle is driven correctly and with asafety distance suitable for the speed.
Pedestrians
Optimal examples of what the system considers to be apedestrian: clear body contours.
For optimal performance, the system's functionfor pedestrian detection needs the clearest pos-sible information about body and bicycle con-tours. This entails being able to detect the con-tours of the pedestrian's head, arm, shoulders,legs, torso and lower body in combination withnormal human movements.
In order to detect a pedestrian, there must be acontrast to the background, which could dependon clothing, weather conditions, etc. If there is lit-tle contrast, the person may be detected late ornot at all, which may result in a delayed reactionfrom the system or no reaction at all.
City Safety can detect pedestrians even in darkconditions if they are illuminated by the vehicle'sheadlights.

WARNING
City Safety is supplementary driver support,but it cannot detect all pedestrians in all sit-uations and, for example, cannot see:
partially obscured pedestrians, people inclothing that hides their body contour orpedestrians shorter than 80 cm (32 in.).
pedestrians if the background contrast ofthe pedestrians is poor - warning andbrake interventions may then be late ornot occur at all.
pedestrians who are carrying largeobjects.
The driver is always responsible for ensuringthat the vehicle is driven correctly and with asafety distance suitable for the speed.

Large animals
Optimal examples of what City Safety would interpret asa large animal: stationary or moving slowly and with clearbody contours.
For optimal performance, the system's functionfor detecting large animals (e.g. moose, horses,etc.) needs the clearest possible informationabout body contours. This entails being able todetect the animal straight from the side in combi-nation with normal movements for that animal.
If parts of the animal's body are not visible to thefunction's camera, the system will not be able todetect the animal.
City Safety can detect large animals even in darkconditions if they are illuminated by the vehicle'sheadlights.

WARNING
City Safety is supplementary driver support,but it cannot detect all large animals in all sit-uations and, for example, cannot see:
partially obscured larger animals.
larger animals seen from the front or frombehind.
running or fast moving larger animals.
larger animals if the contrast of the ani-mal's background is poor - warning andbrake interventions may then occur lateor not at all.
smaller animals such as cats and dogs.
The driver is always responsible for ensuringthat the vehicle is driven correctly and with asafety distance suitable for the speed.

WARNING
The "City Safety in crossing traffic" func-tion is supplementary driver supportintended to improve driving safety – itcannot handle all situations in all traffic,weather and road conditions.
Warnings and brake interventions due toa collision risk with an oncoming vehicleoften come very late.
Never wait for a collision warning or forCity Safety to intervene.
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 incrossing traffic
In certain situations, it may be difficult for CitySafety to help the driver avoid a collision withcrossing traffic.
For example:
on slippery roads when Electronic StabilityControl (ESC) is actively operating
if an approaching vehicle is detected at a latestage
if the oncoming vehicle is partially obstructedby another vehicle or object
if the oncoming vehicle's headlights are off
if the oncoming vehicle is moving erraticallyand e.g. suddenly changes lanes at a latestage.
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".

Market limitations
City Safety is not available in all countries. If CitySafety is not shown in the center display'sSettings menu, your vehicle is not equipped withthis function.
