The radar unit is placed inside the upper section of the windscreen together with the car's cameraunit.
IMPORTANT
Do not place, stick or mount anything on the outside or inside of the windscreen in front ofor around the camera and radar unit — thiscan interfere with camera and radar-depend-ent functions. This may mean that functions are reduced, deactivated completely or give incorrect func-tion response.
If the driver display shows this symbol with the message Windscreen
sensor Sensor blocked, see
Owner's manual, it means that the
camera and radar unit cannot detect other vehi- cles in front of the car.
The following table presents examples of possi- ble causes for a message being shown, alongwith the appropriate action:
Cause Action
The windscreen surface in front of the camera and radar unit is dirty or cov- ered with ice or snow. Clean dirt, ice and snow from the windscreen surface in front of the cameraand radar unit.
Thick fog and heavy rain or snow block the radar signals or the cameraview. No action. Sometimes the unit does not work during heavy rain or snowfall.

Limitations of the camera unit
The camera unit has certain limitations - which in turn also limits those functions that use the unit.
Impaired visionThe camera has limitations similar to the human eye, i.e. it can "see" worse in for example intensesnowfall or rain, dense fog, heavy dust stormsand snow flurries. Under such conditions, thefunctions of camera-dependent systems could besignificantly reduced or temporarily disengaged. Strong oncoming light, reflections in the carriage- way, snow or ice on the road surface, dirty roadsurfaces or unclear lane markings can also sig-nificantly reduce camera function when it is usedto scan the carriageway to detect pedestrians,cyclists, large animals and other vehicles.

WARNING
City Safety is an aid and does not work in all driving situations, traffic, weather and roadconditions. Warning only activated in the event of a high risk for collision. This section and the section"Limitations for City Safety" inform about limi-tations that the driver should be aware ofbefore using City Safety. Warnings and brake interventions for pedes- trians and cyclists are deactivated at vehiclespeeds above 70 km/h (43 mph). City Safety's auto-brake function can prevent a collision or reduce collision speed. Toensure full brake performance, the drivershould always depress the brake pedal - evenif the car auto-brakes. City Safety does not activates any auto-brake functions in the event of heavy acceleration. The driver is always responsible for maintain- ing the correct distance and speed - neverwait for a collision warning or for City Safetyto intervene.
Market limitationCity Safety is not available in all countries. If City Safety does not appear in the centre display's
Settings menu, the car is not equipped with this
function. Search path in the top menu:

Acoustic warning signal in the event of a risk of collision
Warning signal in the event of a risk of colli- sion
Distance measurement with the camera and radar unit
City Safety carries out three steps in the follow-ing order:
1. Collision warning
2. Brake support
3. Auto Brake
Collision warning
The driver is first warned of a potentially immi- nent collision. City Safety can detect pedestrians, cyclists or vehicles that are stationary or moving in the samedirection as the car and are ahead. City Safetycan also detect pedestrians, cyclists or large ani-mals that are crossing the road in front of the car. In the event of a risk of collision with a pedes- trian, large animal, cyclist or vehicle (includingvehicles described in the "City Safety in crosstraffic" section), the driver's attention is alerted bymeans of a red flashing warning signal, an acous-tic signal and a haptic warning in the form of abrake pulse. At lower speeds or with hard brakingor acceleration there will be no haptic warning.The brake pulse frequency varies according tothe car's speed.
Brake support
If the risk of collision has increased further after the collision warning then the brake support isactivated. Brake support reinforces the driver

Auto Brake
The automatic brake function is activated last. If in this situation the driver has not yet started to take evasive action and the risk of collision isimminent then the automatic braking function isdeployed - this takes place irrespective ofwhether or not the driver brakes. Braking thentakes place with full brake force in order toreduce collision speed, or with limited brake forceif it is sufficient to avoid a collision. In connection with automatic braking the seatbelt tensioner may also be activated. For more infor-mation see the "Seatbelt tensioner" section. In some situations, the action of Auto-brake may begin with light braking and then progress to fullbrake action. When City Safety has prevented a collision with a stationary object, the car remains stationary inanticipation of positive action by the driver. If thecar has been braked to avoid collision with aslower vehicle in front, its speed is reduced tomatch that of the vehicle in front.
NOTE
On cars with manual gearbox, the engine stops when the Auto-brake function has stop-ped the car, unless the driver has managed todepress the clutch pedal beforehand.
The driver can always interrupt a braking inter- vention by firmly depressing the acceleratorpedal.
NOTE
When City Safety™ brakes, the brake lights
come on.
When City Safety is activated and brakes the vehicle, the driver display shows a text messageto the effect that the function is/has been active.
WARNING
City Safety must not be used as an excuse for the driver to change his/her driving style. Ifthe driver relies solely on City Safety to do thebraking, there might be a risk of a collisionsooner or later.

Setting the warning distance for City Safety
City Safety is always activated, but it is possible to select the warning distance for the function.
NOTE
The City Safety function cannot be deacti- vated. It is activated automatically when theengine/electric operation is started andremains switched on until the engine/electricoperation is switched off.
The warning distance determines the sensitivity of the system and regulates the distance atwhich the visual, acoustic and haptic warningsshall be triggered. 1. Tap on
Settings in top view in the centre
display.
2. Press
My CarIntelliSafe.
3. Under
City Safety Warning, select Late,Normal or Early to set the desired warning
distance.
If the
Early setting produces too many warnings,
which could be perceived as irritating in certain situations, then use the
Normal or Late warning
distance. If warnings are perceived as being too frequent or disturbing then the warning distance can bereduced. This would lead to the system warning

has the opportunity to avoid a collision via a steering manoeuvre. However, if City Safety anticipates that an evasive manoeuvre is not possible due to traffic in anadjacent lane, the function can assist the driverby automatically starting to brake at an earlierstage.
WARNING
City Safety's ability to anticipate a certain sit- uation is an aid, and does not work in all driv-ing situations or traffic, weather and road con-ditions. The driver always bears ultimate responsibility for ensuring that the vehicle is driven safelyand that applicable laws and road traffic regu-lations are followed.

Limitations of City Safety
The City Safety function may have limitations in certain situations.
Surroundings
Low objects
Low-hanging objects, e.g. a flag/pennant for pro- jecting load, or accessories such as auxiliarylamps and bull bars that are higher than the bon-net limit the function.
Skidding
On slippery road surfaces the braking distance is extended, which may reduce the capacity of CitySafety to avoid a collision. In such situations, theanti-lock brakes and the stability control ESC willgive the best possible braking force with main-tained stability.
Oncoming light
The visual warning signal in the windscreen may be difficult to notice in the event of strong sun-light, reflections, when sunglasses are beingworn or if the driver is not looking straight ahead.
Heat
In the event of high passenger compartment temperature caused by e.g. strong sunlight, thevisual warning signal in the windscreen may betemporarily disengaged.
The camera and radar unit's field of view
The camera's field of vision is limited, which is why pedestrians, large animals, cyclists and vehi- cles in some situations cannot be detected, orthey are detected later than anticipated. Dirty vehicles may be detected later than others and if it is dark, motorcycles may be detected lateor not at all. If a text message in the driver display indicates that the camera and radar unit is obstructed, CitySafety may be unable to detect pedestrians, largeanimals, cyclists, vehicles or road lines ahead ofthe car. This means that the functionality of CitySafety may be reduced. However, an error message is not shown in all situations where the windscreen sensors areobstructed. The driver must therefore take care tokeep the area of windscreen in front of the cam-era and radar unit clear.
IMPORTANT
Maintenance and replacement of City Safety components must only be performed by aworkshop - an authorised Volvo workshop isrecommended.
Driver intervention
Reversing
When your own car is reversing, City Safety is temporarily deactivated.

Indicator lamp
The BLIS button in the centre display's func- tion view activates/deactivates the function.
Principle of Blind Spot Information
Zone in blind spot
Zone for quickly approaching vehicle.
The BLIS function is active at speeds above 10 km/h (6 mph). The system is designed to react when: • your car is overtaken by other vehicles
• another vehicle is quickly approaching your car.
When BLIS detects a vehicle in Zone 1 or aquickly approaching vehicle in Zone 2, the indica-tor lamp on the door mirror on the affected sideilluminates with a constant glow. If the driver acti-vates the direction indicator on the same side asthe warning, the indicator lamp will change over from a constant glow to flashing with a moreintense light.
NOTE
The lamp illuminates on the side of the car where the system has detected the vehicle. Ifthe car is overtaken on both sides at thesame time then both lamps illuminate.
WARNING
Blind Spot Information does not work on sharp bends. Blind Spot Information does not work when the car is reversing.
WARNING
Blind Spot Information is a supplementary aid and does not work in all situations. Blind Spot Information is no substitute for a safe driving style and the use of rearview anddoor mirrors. Blind Spot Information can never replace responsibility and attention by the driver. It isalways the driver
