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 58
) 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.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain generallimitations.

Rear Collision Warning *59
The Rear Collision Warning 60
(RCW) function
can help the driver avoid rear-end collisions from vehicles approaching from behind.
The function can alert drivers of following vehi- cles of the risk of a collision by rapidly flashingthe turn signals. If, at a speed below 30 km/h (20 mph), the function detects that the vehicle is in dangerof being hit from behind, the seat belt tension-ers may tension the front seat belts. TheWhiplash Protection System will also be acti-vated in a collision. Immediately before a collision from behind, the function may also activate the brakes inorder to reduce the forward acceleration of thevehicle during the collision. However, thebrakes will only be applied if your vehicle isstationary. The brakes will be immediatelyreleased if the accelerator pedal is depressed. The function is automatically activated each time the engine is started.
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.

BLIS
*
The BLIS 62
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).

Cross Traffic Alert *67
Cross Traffic Alert(CTA) is a supplementary driver support system to BLIS 68
that is
intended to help the driver detect vehicles crossing behind the vehicle while backing up. The auto-brake subfunction can help the
driver stop the car if there is a risk of collision with an unobserved vehicle.
Examples of areas in which CTA can help the driver detect obstacles while backing up.
CTA supplements BLIS by detecting traffic crossing from the side, e.g. when backing outof a parking space. CTA is primarily designed to detect vehicles, but in certain cases can also detect pedes-trians or smaller 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 approaching your vehicle from the side:
an audible signal will sound from eitherthe left or right speaker, depending onwhich side of your vehicle the object isapproaching from.
an icon will illuminate in the
Park Assist
System graphic on the screen.
an icon will appear in the Park Assist Cam- era's Top view.

If the driver does not pay attention to the warning from CTA and a collision is unavoida- ble, the
auto brake function will intervene to
stop the vehicle and a text will be shown onthe instrument panel to explain why the vehi-cle was braked.
