Auto-hold braking with driver support
The driver support functions Adaptive Cruise Control * and Pilot Assist * have a special brake
function in slow traffic and while stationary.
Braking function in slow traffic and at a standstill
In slow-moving, stop-and-go traffic or when stopped at a traffic light, driving will resumeautomatically if the vehicle is stopped for lessthan approx. 3 seconds. If it takes more than 3seconds for the vehicle ahead to begin movingagain, the driver support function will go intostandby mode and the auto-hold brake func-tion will activate.
–The function can be reactivated by:
Pressing the
button on the steer-
ing wheel keypad.
Pressing the accelerator pedal.
> The function will resume following the vehicle ahead if it begins to move within approx. 6 seconds.
WARNING
A noticeable increase in speed may follow when the speed is resumed with the
steering wheel button.
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.
NOTE
Driver support can keep the vehicle sta- tionary for no more than 5 minutes – afterthat time the parking brake is applied andthe function is deactivated. The parking brake must be released before driver support can be reactivated.

Curve Speed Assist (CSA) *44
Curve Speed Assist can help the driver
reduce speed before sharp turns if the preset speed for the driver support function Adap- tive Cruise Control * or Pilot Assist * is deter-
mined to be too high.
This assessment is performed using informa- tion from map data in the vehicle's navigation system, Sensus Navigation *. After the turn,
the vehicle will resume the previously set speed.
As the function reduces thevehicle's speed, this symbolwill be displayed in the instru-ment panel.
The driver can cancel the function at any time by braking or using the accelerator pedal.
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.
Drive modes
Cornering assistance varies depending on the selected drive mode. If drive mode cannot be selected, the function will use the
Comfortoption. In Dynamic mode, cornering will be
sporty, with slightly more powerful accelera- tion coming out of curves.

Camera/radar sensor limitations The camera and radar sensor used by several of the driver support functions has certainlimitations, which also affect the functionsusing the camera and radar sensor. The drivershould be aware of the following limitations:
Camera and radar
Obstructed camera
The area marked in the illustration must be cleaned regularly and kept free of decals, objects, solar film,etc.
The camera is located on the upper interior section of the windshield along with the radarsensor. Do not place, affix or mount anything on the inside or outside of the windshield, or in frontof or around the camera and radar sensor –this could disrupt camera and radar-basedfunctions. It could cause functions to bereduced, deactivated completely or to producean incorrect function response.If this symbol and the message “
Windscreen sensor Sensor
blocked, see Owner's manual” is
displayed in the instrument panel, it
means that the camera and radar sensor are unable to detect other vehicles, cyclists,pedestrians and large animals in front of thevehicle and that the vehicle's camera andradar-based functions may be obstructed.
The following table shows some of the situa- tions that can cause the message to be dis-played, and suggested actions:
Cause Action
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, iceand snow.
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 sensorfrom functioning.

Park Assist Camera *
Blind sectors
There are "blind" sectors between the cameras' fields of vision.
With Park Assist Camera's 360° view *
selected, objects/obstacles may not be detected if they are located in the "joints"where the edges of the individual cameraviews meet.
WARNING
Even if it seems as though only a fairly small section of the screen image isobstructed, this may mean that a relativelylarge sector is hidden and obstacles theremay not be detected until they are verynear the vehicle.
Defective camera
If a camera sector is dark and contains this symbol, thisindicates that the camera isnot functioning properly. See the following illustration for an example.
The vehicle's left-side camera is malfunctioning.
A dark camera sector may also be displayed in the following situations, but without the
defective camera symbol: a door is open
the trunk lid is open
a rearview mirror is folded in
Lighting conditions
The camera image is automatically adjusted according to the current lighting conditions.This means that the brightness and quality of the image may vary slightly. Poor lighting con-ditions may result in reduced image quality.
Rear Park Assist Camera
NOTE
A bike carrier and other accessories moun- ted on the rear of the vehicle can obscurethe camera's view.

1 - Collision warning
The driver is first alerted to the risk of an immi- nent collision. In vehicles equipped with a head-up display *,
a flashing warning symbol will be displayed on the windshield.
Collision warning symbol on the windshield.
NOTE
Visual warnings on the windshield may be difficult to notice in cases of strong sun-light, reflections, extreme light contrasts,or if the driver is wearing sunglasses or isnot looking straight ahead.
City Safety can detect pedestrians, cyclists or vehicles that are stationary, are moving in thesame direction as your vehicle and are aheadof your vehicle. City Safety can also detect pedestrians, cyclists or large animals that arecrossing the road in front of your vehicle. If there is a risk of a collision with a pedestrian, large animal, cyclist or another vehicle, thedriver will be alerted with light, sound and pul-sations in the brake pedal. At lower speeds,during hard braking or if the accelerator pedalis pressed, the brake pedal pulsation warningwill not be given. The intensity of the brakepedal pulsations varies according to the vehi-cle's speed.
2 - Brake assistance
If the risk of a collision increases after the colli- sion warning, brake support will be activated. If the system determines that the pressure the driver is exerting on the brake pedal is insuffi-cient to prevent the collision, brake supportwill increase pressure.
3 - Auto-brake
The automatic braking function is activated at the last moment. If the driver has not taken evasive action by this stage and a collision is imminent, theautomatic braking function will be triggered.This occurs whether or not the driver is press-ing the brake pedal. Full braking force will beapplied to reduce the speed at impact orreduced braking effect will be applied if this issufficient to avoid the collision.
The seat belt tensioner may be activated whenthe automatic braking function is triggered. In certain situations, auto-braking may begin with a limited braking force before applyingfull braking force. If City Safety has prevented a collision, the vehicle will be kept at a standstill until thedriver takes action. If the vehicle has slowed toavoid colliding with a slower-moving vehicleahead, your speed will be reduced to that vehi-cle's speed. Auto-braking can always be cancelled if the driver presses hard on the accelerator pedal.
NOTE
When City Safety activates the brakes, the brake lights come on.
When City Safety applies the brakes, a text message will appear in the instrument panelto notify the driver that the function is/wasactivated.
WARNING
City Safety may not be used to change how the driver operates the vehicle. Thedriver must not only rely on City Safety tobrake the vehicle.

is always active, but the func-
tion's warning distance can be adjusted.
NOTE
The City Safety function cannot be deacti- vated. It is activated automatically eachtime the engine/electric motor is started.
The alert distance determines the sensitivity of the system and regulates the distance atwhich the light, sound and brake pulsationswill be activated. To select warning distance:
1. Select
SettingsMy CarIntelliSafein the center display's Top view.
2. Under
City Safety Warning, tap Late,Normal or Early to set the desired warn-
ing distance.
If the driver feels that the
Early setting is giv-
ing too many warnings or finds them irritating, the
Normal or Late warning distance settings
can be selected instead. If the driver feels that the warnings are too fre- quent and distracting, the warning distancecan be reduced. This will reduce the total number of warnings, but it will also result inCity Safety providing warnings at a later stage. The
Late warning distance setting should
therefore only be used in exceptional cases, such as when a more dynamic driving style ispreferred.

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.

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.
Market limitationsCity Safety is not available in all countries. If City Safety is not shown in the center display's
Settings menu, your vehicle is not equipped
with this function. In the center display's Top view, tap:
