CauseAction
The area of the windshield in front of the camera/radar sensor is dirty or covered by ice or snow. Clean the windshield in front of the camera/radar sensor and remove dirt, ice andsnow.
Thick fog, heavy rain or snow is blocking the radar signals or thecamera's range of visibility. No action. Heavy precipitation may sometimes prevent the camera/radar sensor fromfunctioning.
Water or snow is spraying/swirling up and blocking the radar signalsor the camera's range of visibility. No action. Very wet or snow-covered roads may sometimes prevent the camera/radar sensor from functioning.
There is dirt between the inside of the windshield and the camera/radar sensor. Consult a workshop to have the area of the windshield on the inside of the camera'scasing cleaned. An authorized Volvo workshop is recommended.
Bright sunlight No action. The camera/radar sensor will reset automatically when lighting conditionsimprove.
NOTE
Keep the windshield in front of the camera and radar unit clean.
High temperaturesIf the temperature in the passenger compartment is very high, the camera/radar sensor will switchoff temporarily for approx. 15 minutes after theengine is started to protect its electronic compo-nents. When the temperature has cooled suffi-ciently, the camera/radar sensor will automati-cally restart.
Damaged windshield
CAUTION
If there are cracks, scratches or stone chips on the windshield in front of any of the cam-era and radar unit "windows" and this coversan area of about 0.5 × 3.0 mm(0.02 × 0.12 in.) or more, contact a workshopto have the windshield replaced – an author-ized Volvo workshop is recommended. Failure to take action could result in reduced performance for the driver support systemsthat use the camera and radar unit.
It could cause functions to be reduced, deac- tivated completely or produce an incorrectfunction response. To avoid the risk of loss of function, malfunc- tion or reduced function of the driver supportsystems that use the radar unit, the followingalso apply:
• Volvo advises
against repairing cracks,
scratches or stone chips in the area infront of the camera and radar unit – theentire windshield should instead bereplaced.
• Before replacing the windshield, contactan authorized Volvo workshop to verify

City Safety
™
City Safety can alert the driver with light, sound and pulsations in the brake pedal to help thedriver detect pedestrians, cyclists, large animalsand vehicles that appear suddenly – the vehiclewill then attempt to automatically brake if thedriver does not act within a reasonable amountof time.
Location of the camera and radar sensor 75
.
City Safety can help prevent a collision or lower the vehicle's speed at the point of impact. City Safety is an aid intended to assist the driver if a collision with a pedestrian, large animal,cyclist or vehicle is imminent. City Safety can help the driver avoid a collision when e.g. driving in stop-and-go traffic, when changes in the traffic ahead and driver distractioncould lead to an incident. The function assists the driver by automatically applying the brakes if there is an imminent risk ofa collision and the driver does not react in time bybraking and/or steering away. City Safety activates a brief, forceful braking in an attempt to stop your vehicle immediately behindthe vehicle or object ahead. City Safety is activated in situations in which the driver should have applied the brakes much ear-lier, which means that the system will not be ableto assist the driver in all situations. City Safety is designed to be activated as late as possible to help avoid unnecessary intervention. Normally, the occupants of the vehicle will not be aware of City Safety except when the systemintervenes when a collision is imminent.

WARNING
•The City Safety function is supplementary driver support intended to help improvedriving safety – it cannot handle all situa-tions in all traffic, weather and road condi-tions.
• The City Safety auto-brake function canprevent a collision or reduce collisionspeed, but to ensure full brake perform-ance the driver should always depress thebrake pedal – even when the car auto-brakes.
• The warning and steering assistance areonly activated if there is a high risk of col-lision – you must therefore never wait forthe collision warning or City Safety tointervene.
• Warnings and brake interventions forpedestrians and cyclists are disengagedat vehicle speeds over 80 km/h(50 mph).
• City Safety does not activate auto-brakingintervention during heavy acceleration.
• 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.
• The driver is advised to read all sections in the Owner's Manual that relate to CitySafety to learn about factors such as itslimitations and what the driver should beaware of before using the system (seethe list of links for all subsections).

City Safety parameters and sub-functions
City Safety can help avoid a collision with a vehi- cle, cyclist or large animal ahead by reducing thevehicle's speed using its automatic braking func-tion. If the difference in speed is greater than the speeds specified below, the City Safety auto-brake function cannot prevent a collision, but itcan help mitigate its effects.
Vehicles
City Safety can help prevent a collision with a vehicle ahead by reducing your vehicle's speedby up to 60 km/h (37 mph).
Cyclists
City Safety can help prevent a collision with a cyclist ahead by reducing your vehicle's speed byup to 50 km/h (30 mph).
Pedestrians
City Safety can help prevent a collision with a pedestrian ahead by reducing your vehicle'sspeed by up to 45 km/h (28 mph).

340and lower body in combination with normal human 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 riding on 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 the cyclist 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 ensuring that the vehicle is driven correctly and with asafety distance suitable for the speed.
Pedestrians
Optimal examples of what the system considers to be a pedestrian: clear body contours.
For optimal performance, the system's function for 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 a contrast 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 dark conditions 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 in clothing 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 ensuring
that the vehicle is driven correctly and with a safety distance suitable for the speed.

Large animals
Optimal examples of what City Safety would interpret as a large animal: stationary or moving slowly and with clearbody contours.
For optimal performance, the system's function for 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 the function's camera, the system will not be able todetect the animal. City Safety can detect large animals even in dark conditions 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 from behind.
• 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 ensuring that the vehicle is driven correctly and with asafety distance suitable for the speed.

City Safety in crossing traffic
City Safety can assist the driver when turning in the path of an oncoming vehicle in an intersec-tion.
: Sector in which City Safety can detect an oncoming
vehicle in crossing traffic.
In order for City Safety to detect an oncoming vehicle in situations where there is a risk of a col-lision, that vehicle must be within the sector inwhich City Safety can analyze the situation. The following criteria must also be met:
• your vehicle's speed must be at least 4 km/h (3 mph)
• your vehicle must be making a left turn
• the oncoming vehicle's headlights must beon

Limitations of City Safety incrossing traffic
In certain situations, it may be difficult for City Safety to help the driver avoid a collision withcrossing traffic.
For example:
• on slippery roads when Electronic Stability Control (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 camera unit, which has some general limitations – see thesection "Camera unit limitations".

City Safety and delayed evasivemaneuvers City Safety can assist the driver by automatically braking the vehicle when it is not possible toavoid a collision by steering alone.
City Safety assists the driver by periodically attempting 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 escape routes 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 automatically apply 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 a certain 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.

WARNING
•Warnings and brake interventions can be triggered 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 for pedestrians 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.
