Park Assist Camera *
Blind sectors
There are "blind" sectors between the cameras' fields ofvision.
With Park Assist Camera's 360° view* selected,objects/obstacles may not be detected if theyare located in the "joints" where the edges of theindividual camera views meet.

WARNING
Even if it seems as though only a fairly smallsection of the screen image is obstructed, thismay mean that a relatively large sector is hid-den and obstacles there may not be detecteduntil they are very near the vehicle.
Defective camera
If a camera sector is dark andcontains this symbol, this indi-cates that the camera is notfunctioning properly.
See the following illustration foran example.
The vehicle's left-side camera is malfunctioning.
A dark camera sector may also be displayed inthe following situations, but without the defectivecamera symbol:
a door is open
the trunk lid is open
a rearview mirror is folded in

Lighting conditions
The camera image is automatically adjustedaccording to the current lighting conditions. Thismeans that the brightness and quality of the
image may vary slightly. Poor lighting conditionsmay result in reduced image quality.
Rear Park Assist Camera
WARNING
Be extra cautious whenreversing if this symbol isshown when a trailer, bikecarrier or similar is attachedand electrically connectedto the vehicle.
The symbol indicates thatthe rear parking assist sensors are deacti-vated and will not warn of any obstacles.

NOTE
A bike carrier and other accessories mountedon the rear of the vehicle can obscure thecamera's view.

City Safety™
City Safety47 can alert the driver with light,sound and pulsations in the brake pedal to helpthe driver detect pedestrians, cyclists, large ani-mals and vehicles that appear suddenly – thevehicle will then attempt to automatically brake ifthe driver does not act within a reasonableamount of time.
Location of the camera and radar sensor.
City Safety can help prevent a collision or lowerthe vehicle's speed at the point of impact.
City Safety is an aid intended to assist the driverif a collision with a pedestrian, large animal,cyclist or vehicle is imminent.
City Safety can help the driver avoid a collisionwhen e.g. driving in stop-and-go traffic, when
changes in the traffic ahead and driver distractioncould lead to an incident.
The function assists the driver by automaticallyapplying the brakes if there is an imminent risk ofa collision and the driver does not react in time bybraking and/or steering away.
City Safety activates a brief, forceful braking in anattempt to stop your vehicle immediately behindthe vehicle or object ahead.
City Safety is activated in situations in which thedriver should have applied the brakes much ear-lier, which means that the system will not be ableto assist the driver in all situations.
City Safety is designed to be activated as late aspossible to help avoid unnecessary intervention.
Normally, the occupants of the vehicle will not beaware of City Safety except when the systemintervenes when a collision is imminent.

WARNING
The City Safety auto-brake function canprevent a collision or reduce collisionspeed, but to ensure full brake perform-ance the driver should always depress thebrake pedal – even when the car auto-brakes.
The warning and steering assistance areonly activated if there is a high risk of col-lision – you must therefore never wait forthe collision warning or City Safety tointervene.
Warnings and brake interventions forpedestrians and cyclists are disengagedat vehicle speeds over 80 km/h(50 mph).
City Safety does not activate auto-brakingintervention during heavy acceleration.

Large animals
If there is a risk of colliding with a large animal,City Safety can help reduce your vehicle's speedby up to 15 km/h (9 mph).
The braking function for large animals is primarilyintended to mitigate the force of a collision athigher speeds. Braking is most effective atspeeds above 70 km/h (43 mph) and less effec-tive at lower speeds.

City Safety sub-functions
Function overview.
Acoustic collision warning signal
Collision warning symbol
Camera/radar sensor distance monitoring
City Safety carries out three steps in the follow-ing order:
1.Collision warning
2. Brake assistance
3. Auto-brake
Descriptions of what happens in these threesteps are provided below.
1 - Collision warning
The driver is first alerted to the risk of an immi-nent collision.
In vehicles equipped with a head-up display*, aflashing warning symbol will be displayed on thewindshield.
Collision warning symbol on the windshield.
NOTE
Visual warnings on the windshield may be dif-ficult to notice in cases of strong sunlight,reflections, extreme light contrasts, or if thedriver is wearing sunglasses or is not lookingstraight ahead.
City Safety can detect pedestrians, cyclists orvehicles that are stationary, are moving in thesame direction as your vehicle and are ahead ofyour vehicle. City Safety can also detect pedes-trians, cyclists or large animals that are crossingthe road in front of your vehicle.
If there is a risk of a collision with a pedestrian,large animal, cyclist or another vehicle, the driverwill be alerted with light, sound and pulsations inthe brake pedal. At lower speeds, during hardbraking or if the accelerator pedal is pressed, thebrake pedal pulsation warning will not be given.The intensity of the brake pedal pulsations variesaccording to the vehicle'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 thedriver is exerting on the brake pedal is insufficientto prevent the collision, brake support willincrease pressure.

WARNING
The driver support system only issues a warn-ing for obstacles detected by its radar sensor– thus, a warning may come after a delay ornot at all.
Never wait for a warning or assistance.Apply the brakes when necessary.

WARNING
The function is supplementary driver sup-port intended to facilitate driving and helpmake it safer – it cannot handle all situa-tions in all traffic, weather and road condi-tions.
The driver is advised to read all sectionsin the Owner's Manual about this functionto learn of its limitations, which the drivermust be aware of before using the func-tion.
Driver support functions are not a substi-tute for the driver's attention and judg-ment. The driver is always responsible forensuring the vehicle is driven in a safemanner, at the appropriate speed, with anappropriate distance to other vehicles,and in accordance with current trafficrules and regulations.

Limitations of City Safety incrossing traffic
In certain situations, it may be difficult for CitySafety to help the driver avoid a collision withcrossing traffic.
For example:
on slippery roads when Electronic StabilityControl (ESC) is actively operating
if an approaching vehicle is detected at a latestage
if the oncoming vehicle is partially obstructedby another vehicle or object
if the oncoming vehicle's headlights are off
if the oncoming vehicle is moving erraticallyand e.g. suddenly changes lanes at a latestage.

City Safety steering assistance forevasive maneuver
City Safety steering assistance can help thedriver steer away from a vehicle/obstacle when itis not possible to avoid a collision by brakingalone. City Safety steering assistance is alwaysactivated and cannot be switched off.
Your vehicle swerves away
Slow-moving/stationary vehicle or obstacle.
City Safety helps provide assistance by strength-ening the driver's steering movements, but only ifthe driver has begun evasive action and the sys-tem detects that the driver's steering movementsare not sufficient to avoid a collision.
The brake system is used simultaneously to fur-ther strengthen steering movements. The func-
tion also helps stabilize the vehicle after it haspassed the obstacle.
City Safety steering assistance can detect:
vehicles
cyclists
pedestrians
large animals

City Safety and delayed evasivemaneuvers
City Safety can assist the driver by automaticallybraking the vehicle when it is not possible toavoid a collision by steering alone.
City Safety assists the driver by periodicallyattempting to predict possible "escape routes" tothe sides of the vehicle in the event a slow-mov-ing or stationary vehicle were to be detected at alate stage.
Your vehicle (1) cannot detect any potential escaperoutes for veering away from the vehicle ahead (2) andmay therefore apply the brakes at an earlier stage.

Slow-moving/stationary vehicles
City Safety will not intervene to automaticallyapply the brakes if it is possible for the driver toavoid a collision by steering the vehicle.

City Safety limitations
City Safety48 functionality may be reduced incertain situations.
Surroundings
Low objects
Hanging objects, such as flags for overhangingloads or accessories such as auxiliary lights orfront protective grids that extend beyond theheight of the hood, may limit City Safety function-ality.

Slippery road conditions
The extended braking distance on slippery roadsmay reduce City Safety's capacity to help avoid acollision. In these types of situations, the Anti-lock Braking System and Electronic Stability Con-
trol (ESC49) will help provide optimal brakingpower with maintained stability.

Backlighting
The visual warning signal in the windshield maybe difficult to detect in bright sunlight, if there arereflections, or if the driver is wearing sunglassesor not looking straight ahead.

Heat
If the temperature in the passenger compartmentis high due to e.g. bright sunlight, the visual warn-ing signal in the windshield may be temporarilydisabled.

Camera and radar sensor's field of vision
The camera's field of vision is limited and in cer-tain situations, it may be unable to detect pedes-trians, large animals, cyclists or vehicles, or it maydetect them later than expected.
Vehicles that are dirty may be detected later thanclean vehicles, and in dark conditions, motorcy-cles may be detected late or not at all.
If a text message displayed in the instrumentpanel indicates that the camera/radar sensor isobstructed, it may be difficult for City Safety todetect pedestrians, large animals, cyclists, vehi-cles or lane markings in front of the vehicle. CitySafety functionality may therefore be reduced.
Text messages may not be displayed for all situa-tions in which the windshield sensors areblocked. The driver must therefore always keepthe windshield in front of the camera/radar sen-sor clean.

CAUTION
Maintenance of driver support components
may only performed by a workshop50.

Driver intervention
Backing up
City Safety is temporarily deactivated when thevehicle is backing up.
Low speed
City Safety is not activated at very low speedsunder 4 km/h (3 mph). The system will thereforenot intervene in situations in which your vehicle isapproaching another vehicle very slowly, such aswhen parking.

Active driver
Action by the driver always has priority. CitySafety will therefore not react or will react at alater stage with a warning or intervention in situa-tions in which the driver is clearly steering andoperating the accelerator pedal, even if a collisionis unavoidable.
An active and aware driving style may thereforedelay collision warnings and intervention in orderto minimize unnecessary warnings.
Other limitations
WARNING
Warnings and brake interventions can betriggered late or not at all if the traffic sit-uation or external influences prevent thecamera and radar unit from properlydetecting pedestrians, cyclists, large ani-mals or vehicles ahead of the vehicle.
To be able to detect vehicles at night, itsfront and rear lights must work and illumi-nate clearly.
The camera and radar unit have a limitedrange for pedestrians and cyclists – thesystem can provide effective warningsand brake interventions if the relativespeed is lower than 50 km/h (30 mph).For stationary or slow-moving vehicles,warnings and brake interventions areeffective at vehicle speeds of up to70 km/h (43 mph). Speed reduction forlarge animals is less than 15 km/h(9 mph) and can be achieved at vehiclespeeds over 70 km/h (43 mph). At lowerspeeds, the warning and brake interven-tion for large animals is less effective.
Warnings for stationary or slow-movingvehicles and large animals can be disen-gaged due to darkness or poor visibility.
