can alert the driver with light,
sound and pulsations in the brake pedal to help the driver detect pedestrians, cyclists,large animals and vehicles that appear sud-denly.
Location of the camera and radar sensor.
City Safety can help prevent a collision or lower the vehicle's speed at the point ofimpact. City Safety is an aid intended to assist the driver if a collision with a pedestrian, large ani-mal, cyclist or vehicle is imminent. City Safety can help the driver avoid a collision when e.g. driving in stop-and-go traffic, whenchanges in the traffic ahead and driver distrac-tion could lead to an incident. The function assists the driver by automati-cally applying the brakes if there is an immi-nent risk of a collision and the driver does notreact in time by braking and/or steering away. City Safety activates a brief, forceful braking in an attempt to stop your vehicle immediatelybehind the vehicle or object ahead. City Safety is activated in situations in which the driver should have applied the brakesmuch earlier, which means that the systemwill not be able to assist the driver in all situa-tions. City Safety is designed to be activated as late as possible to help avoid unnecessary inter-vention. Automatic braking will only be appliedafter or during a collision warning. Normally, the occupants of the vehicle will not be aware of City Safety except when the sys-tem intervenes when a collision is imminent.
WARNING

The function is supplementary driver support intended to facilitate drivingand help make it safer – it cannot han-dle all situations in all traffic, weatherand road conditions.
The driver is advised to read all sec-tions in the Owner's Manual about thisfunction to learn of its limitations,which the driver must be aware ofbefore using the function.
Driver support functions are not a sub-stitute for the driver's attention andjudgment. The driver is always respon-sible for ensuring the vehicle is drivenin a safe manner, at the appropriatespeed, with an appropriate distance toother vehicles, and in accordance withcurrent traffic rules and regulations.

can help the driver avoid a colli-
sion with a vehicle, cyclist or large animal ahead by reducing the vehicle's speed usingits automatic braking function.
If the difference in speed is greater than the speeds specified below, the City Safety auto-brake function cannot prevent a collision, butit can 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 speedby up 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).
Large animals
If there is a risk of colliding with a large ani- mal, City Safety can help reduce your vehicle'sspeed by up to 15 km/h (9 mph). The braking function for large animals is pri- marily intended to mitigate the force of a colli-sion at higher speeds. Braking is most effec- tive at speeds above 70 km/h (43 mph) andless effective at lower speeds.

Limitations of City Safety in crossing traffic
In certain situations, it may be difficult for
City Safety to help the driver avoid a collisionwith crossing traffic.
For example:
on slippery roads when Electronic Stability Control (ESC) is actively operating
if an approaching vehicle is detected at alate stage
if the oncoming vehicle is partiallyobstructed by another vehicle or object
if the oncoming vehicle's headlights areoff
if the oncoming vehicle is moving errati-cally and e.g. suddenly changes lanes at alate stage.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain generallimitations.

City Safety steering assistance for evasive maneuver City Safety steering assistance can help the driver steer away from a vehicle/obstaclewhen it is not possible to avoid a collision bybraking alone. City Safety steering assistanceis always activated and cannot be switchedoff.
Your vehicle swerves away
Slow-moving/stationary vehicle or obsta- cle.
City Safety helps provide assistance bystrengthening the driver's steering move-ments, but only if the driver has begun evasiveaction and the system detects that the driver'ssteering movements are not sufficient to avoida collision. The brake system is used simultaneously to further strengthen steering movements. The function also helps stabilize the vehicle after ithas passed the obstacle. City Safety steering assistance can detect:
vehicles
cyclists
pedestrians
large animals

City Safety steering assistance limitations during evasivemaneuvers
City Safety steering assistance may have lim- ited functionality in certain situations and notintervene, e.g.:
at speeds outside the range of 50-100 km/h (30-62 mph)
if the driver does not take evasive action
if speed-dependent power steering wheelresistance is working at reduced power –e.g. during cooling due to overheating.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain generallimitations.

functionality may be reduced in
certain situations.
Surroundings
Low objects
Hanging objects, such as flags for overhang- ing loads or accessories such as auxiliarylights or front protective grids that extendbeyond the height of the hood, may limit City Safety functionality.
Slippery road conditions
The extended braking distance on slippery roads may reduce City Safety's capacity tohelp avoid a collision. In these types of situa-tions, the Anti-lock Braking System and Elec- tronic Stability Control (ESC 61
) are designed
for optimal braking power with maintained stability.
Backlighting
The visual warning signal in the windshield may be difficult to detect in bright sunlight, ifthere are reflections, or if the driver is wearingsunglasses or not looking straight ahead.
Heat
If the temperature in the passenger compart- ment is high due to e.g. bright sunlight, thevisual warning signal in the windshield may betemporarily disabled.
Camera and radar sensor's field of vision
The camera's field of vision is limited and in certain situations, it may be unable to detectpedestrians, large animals, cyclists or vehicles,or it may detect them later than expected. Vehicles that are dirty may be detected later than clean vehicles, and in dark conditions,motorcycles may be detected late or not at all. If a text message displayed in the instrument panel indicates that the camera/radar sensoris obstructed, it may be difficult for City Safetyto detect pedestrians, large animals, cyclists,vehicles or lane markings in front of the vehi-cle. City Safety functionality may therefore bereduced. Text messages may not be displayed for all sit- uations in which the windshield sensors areblocked. The driver must therefore alwayskeep the windshield in front of the camera/radar sensor clean.
CAUTION
Only a workshop may perform mainte- nance on driver support components – anauthorized Volvo workshop is recom-mended.

Driver intervention
Backing up
City Safety is temporarily deactivated when the vehicle is backing up.
Low speed
City Safety is not activated at very low speeds under 4 km/h (3 mph). The system will there-fore not intervene in situations in which yourvehicle is approaching another vehicle veryslowly, such as when parking.
Active driver
Action by the driver always has priority. City Safety will therefore not react or will react at alater stage with a warning or intervention insituations in which the driver is clearly steeringand operating the accelerator pedal, even if acollision is unavoidable. An active and aware driving style may there- fore delay collision warnings and interventionin order to minimize unnecessary warnings.
Other limitations
WARNING
The driver support system only issues a warning for obstacles detected by its radarsensor – thus, a warning may come after adelay or not at all. Never wait for a warning or assistance. Apply the brakes when necessary.
WARNING
Warnings and brake interventions can be triggered late or not at all if the traf-fic situation or external influences pre-vent the camera and radar unit fromproperly detecting pedestrians,cyclists, large animals or vehiclesahead of the vehicle.
To be able to detect vehicles at night,its front and rear lights must work andilluminate clearly.
The camera and radar unit have a lim-ited range for pedestrians and cyclists– the system can provide effectivewarnings and brake interventions if therelative speed is lower than 50 km/h(30 mph). For stationary or slow-mov-ing vehicles, warnings and brake inter-ventions are effective at vehicle speedsof up to 70 km/h (43 mph). Speedreduction for large animals is less than15 km/h (9 mph) and can be achievedat vehicle speeds over 70 km/h(43 mph). At lower speeds, the warn-ing and brake intervention for large ani-mals is less effective.
Warnings for stationary or slow-mov-ing vehicles and large animals can bedisengaged due to darkness or poorvisibility.
Warnings and brake interventions for pedestrians and cyclists are disen-gaged at vehicle speeds over 80 km/h(50 mph).
Do not place, affix or mount anythingon the inside or outside of the wind-shield, or in front of or around the cam-era and radar unit – this could disruptcamera-based functions.
Objects, snow, ice or dirt in the area ofthe camera sensor can reduce thefunction, disengage it completely orgive an improper function response.

WARNING
The City Safety auto-brake function can prevent a collision or reduce colli-sion speed, but to ensure full brakeperformance the driver should alwaysdepress the brake pedal – even whenthe car auto-brakes.
The warning and steering assistanceare only activated if there is a high riskof collision – you must therefore neverwait for the collision warning or CitySafety to intervene.
Warnings and brake interventions forpedestrians and cyclists are disen-gaged at vehicle speeds over 80 km/h(50 mph).
City Safety does not activate auto-braking intervention during heavyacceleration.

The BLIS 65
function is designed to help pro-
vide assistance in heavy traffic with several lanes moving in the same direction by helpingthe driver to detect the presence of vehiclesin the "blind spot" area behind and to the sideof the vehicle.
Location of BLIS indicator light.
BLIS is a driver support system designed to alert the driver of:
vehicles in your "blind spot"
vehicles approaching rapidly in adjacentlanes.
BLIS overview
Blind spot zone
Rapidly approaching vehicle zone.
The system is designed to react to:
vehicles passing your vehicle
vehicles that are rapidly approaching your vehicle from behind.
When BLIS detects a vehicle in zone 1 or arapidly approaching vehicle in zone 2, an indi-cator light will illuminate in the relevant rear-view mirror and glow steadily. If the driverthen uses the turn signal on the side in whichthe warning has been given, the indicator lightwill become brighter and begin flashing. BLIS is active when your vehicle is traveling at a speed over 10 km/h (6 mph).
