Limited field of vision
The radar sensor has a limited field of vision. In some situations, it may detect a vehicle laterthan expected or not at all.
The radar sensor's field of vision.
The radar sensor's detection of vehicles very close to your vehicle may be delayedin certain situations, e.g. if a vehicle pulls in between your vehicle and the vehicledirectly ahead.
Small vehicles, such as motorcycles, or vehicles that are not driving in the centerof the lane may remain undetected.
In curves, the radar may detect the wrong vehicle or lose sight of a target vehicle.
Low trailers
Low trailer in the radar shadow.
Low trailers may also be difficult or even impossible for the radar to detect. The driver should be extra alert when driving behind vehi- cles towing low trailers when Adaptive Cruise Control
* or Pilot Assist * is activated.
Camera
Reduced visibility
Cameras have the same limitations as the human eye. In other words, their “vision" isimpaired by adverse weather conditions suchas heavy snowfall/rain, dense fog, swirlingdust/snow, etc. These conditions may reduce the function of systems that depend on thecamera or cause these systems to temporarilystop functioning. Strong sunlight, reflections from the road sur- face, ice or snow covering the road, a dirtyroad surface, or unclear lane marker lines maydrastically reduce the camera

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.

City Safety™
City Safety 51
can alert the driver with light,
sound and pulsations in the brake pedal to help the driver detect pedestrians, cyclists,large animals and vehicles that appear sud-denly.
Location of the camera and radar sensor.
City Safety can help prevent a collision or lower the vehicle's speed at the point ofimpact. City Safety is an aid intended to assist the driver if a collision with a pedestrian, large ani-mal, cyclist or vehicle is imminent. City Safety can help the driver avoid a collision when e.g. driving in stop-and-go traffic, whenchanges in the traffic ahead and driver distrac-tion could lead to an incident. The function assists the driver by automati-cally applying the brakes if there is an immi-nent risk of a collision and the driver does notreact in time by braking and/or steering away. City Safety activates a brief, forceful braking in an attempt to stop your vehicle immediatelybehind the vehicle or object ahead. City Safety is activated in situations in which the driver should have applied the brakesmuch earlier, which means that the systemwill not be able to assist the driver in all situa-tions. City Safety is designed to be activated as late as possible to help avoid unnecessary inter-vention. Automatic braking will only be appliedafter or during a collision warning. Normally, the occupants of the vehicle will not be aware of City Safety except when the sys-tem intervenes when a collision is imminent.
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.

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.

Setting a warning distance for City Safety
City Safety 53
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.

WARNING
No automatic system can guarantee 100% correct function in all situations.You should therefore never test use ofCity Safety in the direction of people,animals or vehicles – this could lead tosevere damage, serious personal injuryor even death.
City Safety warns the driver if there is arisk of collision, but the function cannotreduce the driver's reaction time.
Even if the warning distance has been set to
Early, warnings may be per-
ceived as late in certain situations – e.g. when there are large speed differ-ences or if the vehicle ahead suddenlybrakes heavily.
With the warning distance set to
Early,
warnings come further in advance. This may cause the warnings to come morefrequently than with warning distance
Normal, but is recommended since it
can make City Safety more effective.
NOTE
The warning with direction indicators for Rear Collision Warning * is deactivated if
the collision warning distance in the City Safety function is set to the lowest level "
Late".
The seat belt tensioning and braking func- tions remain active.

Detecting obstacles with City Safety
City Safety 54
can help the driver detect other
vehicles, cyclists, large animals and pedes- trians.
VehiclesCity Safety can detect most vehicles that are stationary or are moving in the same directionas your vehicle. In some cases, it can alsodetect oncoming vehicles and crossing traffic. For City Safety to be able to detect a vehicle in the dark, its headlights and taillights must beon and clearly visible.
Cyclists
Examples of what City Safety would interpret to be a cyclist: clear body and bicycle shapes.

For good performance, the system's function for cyclist detection needs the clearest possi-ble information about the contours of the bicy-cle and of the cyclist's head, arm, shoulders,legs, torso and lower body in combinationwith normal human movements. If large portions of the cyclist's body or the bicycle itself are not visible to the function'scamera, it will not be able to detect a cyclist. The system can only detect adult cyclists rid- ing on bicycles intended for adults.
WARNING
City Safety is supplementary driver sup- port, but it cannot detect all cyclists in allsituations and, for example, cannot see:
partially obscured cyclists.
cyclists if the background contrast of the cyclist is poor - warning and brakeinterventions may then be late or notoccur at all.
cyclists in clothing that hides theirbody contour.
bikes loaded with large objects.
The driver is always responsible for ensur- ing that the vehicle is driven correctly andwith a safety distance suitable for thespeed.
Pedestrians
Examples of what the system considers to be a pedestrian: clear body contours.
For good performance, the system's function for pedestrian detection needs the clearestpossible information about the contours of thepedestrian's head, arm, shoulders, legs, torsoand lower body in combination with normalhuman movements. In order to detect a pedestrian, there must be a contrast to the background, which coulddepend on clothing, weather conditions, etc. Ifthere is little contrast, the person may bedetected late or not at all, which may result ina delayed reaction from the system or no reac-tion at all. City Safety can detect pedestrians even in dark conditions if they are illuminated by thevehicle's headlights.
WARNING
City Safety is supplementary driver sup- port, but it cannot detect all pedestrians inall situations and, for example, cannot see:
partially obscured pedestrians, people in clothing that hides their body con-tour or pedestrians shorter than 80 cm(32 in.).
pedestrians if the background contrastof the pedestrians is poor - warningand brake interventions may then belate or not occur at all.
pedestrians who are carrying largeobjects.
The driver is always responsible for ensur- ing that the vehicle is driven correctly andwith a safety distance suitable for thespeed.

Large animals
Examples of what City Safety would interpret as a large animal: stationary or moving slowly and withclear body contours.
For good performance, the system's function for detecting large animals (e.g. moose,horses, etc.) needs the clearest possible infor-mation about body contours. This entailsbeing able to detect the animal straight fromthe side in combination with normal move-ments for that animal. If parts of the animal's body are not visible to the function's camera, the system will not beable to detect the animal. City Safety can detect large animals even in dark conditions if they are illuminated by thevehicle's headlights.
WARNING
City Safety is supplementary driver sup- port, but it cannot detect all large animalsin all situations and, for example, cannotsee: partially obscured larger animals.
larger animals seen from the front or from behind.
running or fast moving larger animals.
larger animals if the contrast of the ani-mal's background is poor - warningand brake interventions may thenoccur late or not at all.
smaller animals such as cats and dogs.
The driver is always responsible for ensur- ing that the vehicle is driven correctly andwith a safety distance suitable for thespeed.
