298If City Safety has prevented a collision, the vehi- cle will be kept at a standstill until the drivertakes action. If the vehicle has slowed to avoidcolliding with the vehicle ahead, your speed willbe reduced to that vehicle's speed. When auto-brake is triggered, the seat belt pre- tensioners may also be activated, see the article"Seat belts" for additional information. Auto-braking can be cancelled if the driver presses hard on the accelerator pedal. When City Safety applies the brakes, the brake lights will illuminate. When City Safety is triggered and applies the brakes, a text message will be displayed in theinstrument panel.

City Safety warning level settings
City Safety is always activated but the function's warning distance can be adjusted.
NOTE
City Safety cannot be turned off and activates automatically each time the engine is started.
Setting a warning level (distance)
The distance set for warnings determines the system's responsiveness and sets the distance atwhich visual, audible and tangible (haptic) warn-ings will be triggered. To do so:1. Tap
Settings in the center display's Top
view.
2. Tap
My CarIntelliSafeCity Safety.
3. Choose among
Earlier, Normal or Later.
Begin by choosing
Earlier. If too many warnings
are given, change to Normal.
If the driver feels that warnings are given too often, the warning level can be lowered. Thismeans that warnings will be provided later, result-ing in fewer warnings being given. The setting
Later should only used in exceptional
circumstances, e.g., for a more dynamic driving style.
WARNING
• No automatic system can be guaranteed to function 100% correctly in all situa-tions. For that reason, never test CitySafety by driving toward a person orobject. This could result in serious injuryor death.
• Even if the setting
Earlier has been
selected, warnings may be perceived as being given late, e.g., if the difference inspeed is great or if the vehicle aheadbrakes suddenly.
• City Safety can provide a warning for apotential collision but it can never shortenthe driver's reaction time.
• To help make City Safety as effective as possible, always using the setting
Earlieris recommended.
NOTE
•
Due to local traffic regulations in certain markets, Rear Collision Warning (RCW) will
not activate the rear turn signals.
That part of the function will be deacti- vated.
• The use of the rear turn signals will alsobe deactivated if the City Safety warning level is set at
Later. See also the section

Detecting obstructions with City Safety
City Safety can detect vehicles, cyclists, large animals and pedestrians.
VehiclesCity Safety detects most types of vehicles that are either stationary, moving in the same direc-tion as your vehicle or those described in the arti-cle "City Safety in crossing traffic." In order for City Safety to detect a vehicle in darkness, its headlights and taillights must be onand clearly visible.
Cyclists
Optimal example of what the system considers to be a cyclist: clear body/bike contours
To help function optimally, City Safety's function for cyclist detection needs clear informationabout the bike itself and the rider's head, arms, shoulders, legs, the upper and lower parts of thebody and a cyclist's normal pattern of movement.
• If major parts of the cyclist's body are notvisible to the camera, the system cannotdetect the cyclist.
• The cyclist must be an adult riding a bikeintended for an adult.
WARNING
City Safety is designed to be a supplementary driving aid and cannot detect all cyclists in allsituations, such as:
• a partially obscured cyclist.
• a cyclist whose clothing prevents a clear view of the person's body contours.
• a cyclist transporting a large object.
The driver is always responsible for operating the vehicle in a safe manner.

Pedestrians
Optimal example of what the system considers to be a pedestrian: clear body contours
To help function optimally, City Safety's function for pedestrian detection needs clear informationabout the person's head, arms, shoulders, legs,the upper and lower parts of the body and a per-son's normal pattern of movement. In order to detect a pedestrian, there must be a contrast to the background. If there is little con-trast, the person may be detected late or not atall, which may result in a late or no reaction fromthe system.• If major parts of the pedestrian's body arenot visible to the camera, he/she may not bedetected.
• In order to detect a pedestrian, the systemmust have a full view of the person's entire body and the person must be at least 32 in.(80 cm) tall.
• City Safety can also help detect pedestriansin dark conditions if they are in the path ofthe vehicle's headlights.
WARNING
City Safety is designed to be a supplementary driving aid. It cannot detect pedestrians:
• who are partially obscured, wearing cloth- ing that prevents a clear view of the per-son's body contours or who are not atleast 32 in. (80 cm) tall.
• who have limited contrast to their immedi-ate background. A warning or brakingmay be delayed or not come at all.
• carrying a large object.
The driver is always responsible for operating
the vehicle in a safe manner.
Large animals
Examples of what City Safety considers to be large ani- mals: stationary or moving slowly with clear body con-tours
To function optimally, the system feature for detecting large animals (moose, horses, etc.)must receive as clear information about bodycontours as possible. This entails being able todetect the animal straight from the side andassumes that the animal has a normal pattern ofmovement. If parts of the animal's body are hidden from the camera, the system cannot detect this animal. City Safety can also help detect large animals in dark conditions if they are in the path of the vehi-cle's headlights.

DRIVER SUPPORT
301
WARNING
City Safety is designed to be a supplementary driving aid. It cannot detect large animals in all situations such as:• large animals that are partially obscured
• large animals straight from the front or rear
• large animals that are running or movingquickly
• large animals that have limited contrast totheir immediate background. A warning orbraking may be delayed or not come atall.
• smaller animals such as dogs or cats
The driver is always responsible for operating the vehicle in a safe manner.

City Safety in crossing traffic
City Safety can help the driver when turning in the path of an oncoming vehicle in an intersec-tion.
Turning at an intersection
1. The area in which City Safety can detect an oncoming vehicle
In order for City Safety to detect an approaching vehicle in situations where there is a risk of a col-lision, that vehicle must be within City Safety'srange (the red area in the illustration). The following criteria must also be met:
• your vehicle's speed must be at least 3 mph (4 km/h)
• the approaching vehicle's headlights must beon
• your vehicle must be making a left turn
WARNING
•City Safety is a supplementary driving aid and does not function in all driving situa-tions or in all traffic, weather or road con-ditions.
• Warnings and braking for an approachingvehicle will usually come at a very latestage.
• The driver is responsible for maintaining asafe distance and speed. Never wait for awarning or for City Safety to take action.
Limitations in crossing trafficIn certain situations, it may be very difficult forCity Safety to help the driver avoid a collision withan approaching vehicle in crossing traffic, forexample:
• on slippery roads when Electronic StabilityControl is active
• if the approaching vehicle is detected at alate stage
• If the approaching vehicle is partiallyobscured by another vehicle
• if the approaching vehicle moves erratically(e.g., sudden lane changes at a late stage)

The following table shows some of the situations that can cause the message to be displayed andsuggested actions.
Cause
Action
The area of the wind- shield in front of thecamera/radar sensor isdirty or covered by ice orsnow. Clean the wind-shield or removethe ice/ snow.
Thick fog or heavy rain/snow blocks reduces thecamera/radar sensor'srange of visibility. No action. Thedriver should beextra alert in condi-tions of this type.
There is dirt betweenthe inside of the wind-shield and the camera/radar sensor. Have the area ofthe windshieldcleaned by atrained and quali-fied Volvo servicetechnician.
CAUTION
•
Service and maintenance on City Safety may only be carried out by a trained andqualified Volvo service technician.
• If a crack, scratch or stone chip shouldoccur in the section of the windshield infront the camera/radar sensor, contact atrained and qualified Volvo service techni-cian to repair or replace the windshield.Failing to do so may result in reducedCity Safety functionality.
• This can also result in certain functionsbeing reduced or disabled, or they mayrespond incorrectly.
To help avoid the risk of incorrect, reduced ordisabled functionality for driver support sys-tems using the camera or radar sensors:
• Volvo recommends that cracks, scratchesor stone chips on the windshield in front of the camera/radar sensor should
not
be repaired; in such cases, the entire windshield should be replaced.
• Before the windshield is replaced, con-tact a Volvo retailer to ensure that thecorrect windshield is ordered and instal-led. If the wrong type of windshield isused, this may cause City Safety to func-tion improperly or not at all.
• Volvo recommends the use of only Genu-ine Volvo Replacement Windshields.
• When replacing windshield wipers, use the same type or ones approved by Volvo.
After the windshield has been replaced, thecamera/radar sensor will have to be recalibra-ted by a trained and qualified Volvo servicetechnician to help ensure proper function ofall of the vehicle's camera-/radar-based sys-tems.
MaintenanceIn order for City Safety to function properly, the area of the windshield must be kept free of dirt,ice, snow, etc.
Other vehicle functionsIf a message is displayed in the instrument panel,this means that the other systems using the cam-era/radar sensor (see the list below) will not havefull functionality or may not function at all.

Blind Spot Information (BLIS) *
Blind Spot Information is a system designed to alert the driver to the presence of other vehiclesmoving in the same direction as your vehicle onroads with several lanes.
Blind Spot Information is a driving aid intended to:
• detect other vehicles in your door mirrors'"blind area"
• detect vehicles that are about to pass yourvehicle or are approaching your vehiclequickly from behind in the left and/or rightlanes
WARNING
•
Blind Spot Information is an information system, NOT a warning or safety systemand does not function in all situations.
• Blind Spot Information does not eliminatethe need for you to visually confirm theconditions around you, and the need foryou to turn your head and shoulders tomake sure that you can safely changelanes or back up.
• As the driver, you have full responsibilityfor changing lanes/backing up in a safemanner.
Overview
Blind Spot Information indicators
Indicator light
BLIS button in the center display's Function view to activate/deactivate the function
The indicator light illuminates on the side of thevehicle where the system has detected anothervehicle. If your vehicle is passed on both sides atthe same time, both lights will illuminate.
Principle for Blind Spot Information: Zone 1. Blind area, Zone 2. Area for approaching/passing vehicles
Blind Spot Information functions when your vehi- cle is moving at speeds above approx. 6 mph(10 km/h). Blind Spot Information is designed to react to:
• vehicles that are passing your vehicle
• other vehicles that are rapidly approaching your vehicle
When Blind Spot Information detects a vehicle inzone 1 or a fast-approaching vehicle in zone 2,the indicator light in the respective door mirrorwill glow steadily. If the driver then uses the turn signal on the side on which the warning is given, the indicator lightwill begin flashing and become brighter.

Cross Traffic Alert (CTA) * limitations
CTA functionality may be reduced in certain sit- uations.
LimitationsCTA has limitations in certain situations, for example, the CTA sensors cannot "see" throughother parked vehicles or obstructions. The following are several examples where CTA's "field of vision" may initially be limited andapproaching vehicles cannot be detected untilthey are too close:
The vehicle is pulled far into a parking space
In angled parking spaces, CTA may be "blind" on one side
CTA's blind area
CTA's "field of vision"
However, as you back your vehicle out of a park- ing space, CTA's "field of vision" expands. Examples of other limitations include:
• Dirt, ice or snow obstructing the sensors may reduce the system's function or make itimpossible to detect other vehicles orobjects.
• CTA is deactivated if a trailer's wiring is con-nected to the vehicle's electrical system.
MaintenanceThe CTA sensors are located on the inside of therear fenders/bumper.

Road Sign Information (RSI) *
RSI is a feature that helps the driver see road signs showing the posted speed limit.
Examples of readable road signs
If the vehicle passes a sign showing the speed limit, this will be displayed in the instrument panel and the head-up display *.
NOTE
If the vehicle is equipped with the Sensus Navigation system, speed-related informationis provided by this system in the followinginstances:
• In cases where the speed limit is givenindirectly (e.g., when driving on highwaysor other major roads).
• If a previously read speed limit sign is nolonger considered valid and no new signhas been passed.
If a third-party navigation system is beingused, RSI has no support for speed-relatedinformation.
WARNING
RSI does not function in all situations and is only intended to provide supplementary infor-mation. The driver is always responsible for operating the vehicle safely.

Driver Alert Control limitations
Driver Alert Control (DAC) may have limited or reduced functionality in certain situations.
WARNING
A driving pattern may not change despite driver fatigue, e.g., if a function such as PilotAssist is being used, which means that DACwill not provide a warning. It is always veryimportant to stop and take a break at the firstsign of driver fatigue, even if the system hasnot provided a warning.
In certain situations, DAC may provide warnings even if the driver
