Changing target vehicles and automatic braking with Pilot Assist
At certain speeds, Pilot Assist can change target vehicles and automatically apply the brakes.
Changing target vehicles
If the target vehicle turns suddenly, there may be a sta- tionary vehicle ahead
When Pilot Assist is actively following another vehicle at speeds under 20 mph (30 km/h) and
changes targets from a moving vehicle to a sta- tionary one, the system will brake for the station-ary vehicle.
WARNING
If Pilot Assist changes targets from a moving vehicle to a stationary one at speeds above
20 mph (30 km/h), the system will not react
to the stationary vehicle and will accelerate to the previously set speed. The driver must actively apply the brakes to slow/stop the vehicle.
Automatic standby mode when changing targets
Pilot Assist disengages and goes into standby mode if:
• your vehicle's speed goes below approx.3 mph (5 km/h) and Pilot Assist cannotdetermine if the target object is a stationaryvehicle or some other type of object such asa speed bump, etc
• the vehicle's speed goes below approx.3 mph (5 km/h) and the vehicle aheadchanges lanes or turns so that Pilot Assistno longer has a target vehicle to follow
Auto-hold brake functionIn slow-moving, stop-and-go traffic or when stop-ped at a traffic light, driving will resume automati-cally if the vehicle is not stopped for more thanapprox. 3 seconds. If it takes more than3 seconds for the vehicle ahead to begin movingagain, Pilot Assist will go into standby mode andthe auto-hold brake function will activate.

WARNING
Pilot Assist is not a collision avoidance sys- tem. The driver is always responsible forsteering or applying the brakes if the systemdoes not detect another vehicle. Do not use Pilot Assist in demanding driving conditions such as city driving or other heavytraffic situations, in slippery conditions, whenthere is a great deal of water or slush on theroad, during heavy rain or snow, in poor visibil-ity, on winding roads or on highway on- or off-ramps. In certain situations, it may be difficult for Pilot Assist to assist the driver correctly or to deac-tivate automatically. In such cases, it is advisa-ble not to use Pilot Assist. Examples of suchsituations may be:
• the lane's side market lines are missing, badly faded or cross each other.
• the division of lanes is not clear, e.g.,when a line divides or merges withanother, at exits or if there are many roadsigns/markers.
• there are edges or other lines on or nearthe lane, e.g., curbs, cracks, repairedareas, sharp shadows, etc.
• the lane is narrow or winding.
• the lane is at the top of a hill, on anuneven road surface or over a bump.
•bad weather conditions (rain, snow, fog, slush, poor visibility, backlighting, etc).
The driver should also be aware that Pilot Assist has the following limitations: • High curbs, barriers and temporary obsta- cles (cones, barriers etc) may not bedetected or could be detected incorrectlyas side marker lines, which may create arisk of collision. The driver must ensure asafe distance to these obstacles.
• The camera or radar sensor may not beable to detect objects if there are pot-holes or if there are stationary objectspartially or completely blocking the road.
• Pilot Assist does not "see" pedestrians,animals, etc.
• Pilot Assist's steering capacity is limitedand may not always be able to help thedriver keep the vehicle in the lane.
The driver can always take action to override PilotAssist.
Steep roads and/or heavy loadsPilot Assist is primarily intended for use on rela-tively level roads. The function may not be able tomaintain the correct time interval to the vehicleahead on when driving down steep hills. Thedriver should be attentive and prepared to applythe brakes in these situations. Do not use Pilot Assist when the vehicle is trans-porting a heavy load or if it is towing a trailer.
Additional information
•
The Off Road drive mode cannot be
selected if Pilot Assist is activated.
• Pilot Assist uses the vehicle's camera and radar sensor, which have certain general limi-tations. See the articles "Camera limitations"and "Radar sensor limitations" for additionalinformation.

Camera limitations
The camera used by several of the driver support systems has certain limitations, which also affectthe systems using it.
Reduced visibility
WARNING
• The camera has the same limitations as the human eye. In other words, its “visionis impaired” by adverse weather condi-tions such as heavy snowfall, dense fog,etc. These conditions may reduce thefunction of systems that depend on thecamera or cause these systems to tem-porarily stop functioning.
• Strong sunlight, reflections from the roadsurface, ice or snow covering the road, adirty road surface, or unclear lane markerlines may drastically reduce the camera

DRIVER SUPPORT
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)
