Time interval controls
Press to reduce the time interval to the vehi-cle ahead
Press to increase the time interval to thevehicle ahead
Distance indicator
In order to follow the vehicle ahead as smoothlyas possible, Pilot Assist allows the time interval tovary considerably in certain situations. At lowspeeds, when the distance to the vehicle aheadis short, Pilot Assist increases the time intervalslightly.
•If Pilot Assist does not seem to react when itis put in active mode, this may be becausethe set time interval to the vehicle aheaddoes not allow an increase in speed.
•The higher the speed, the greater the dis-tance to the vehicle ahead for a given timeinterval.

WARNING
•Only use a time interval that is suitable incurrent traffic conditions.
•A short time interval gives the driver lim-ited reaction time if an unexpected situa-tion occurs in traffic.

Changing target vehicles andautomatic braking with PilotAssist-2
At certain speeds, Pilot Assist can change targetvehicles 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 anothervehicle at speeds under 20 mph (30 km/h) andchanges 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 movingvehicle to a stationary one at speeds above20 mph (30 km/h), the system will not reactto the stationary vehicle and will accelerate tothe previously set speed.
The driver must actively apply the brakes toslow/stop the vehicle.

Automatic standby mode when changing
targets
Pilot Assist disengages and goes into standbymode 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 function
In 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 drivingconditions 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 PilotAssist 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 PilotAssist 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 loads
Pilot 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 beselected if Pilot Assist is activated.
•Pilot Assist uses the vehicle's camera andradar 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 supportsystems has certain limitations, which also affectthe systems using it.

Reduced visibility
WARNING
•The camera has the same limitations asthe 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

takes 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 driverpresses hard on the accelerator pedal.
When City Safety applies the brakes, the brakelights will illuminate.
When City Safety is triggered and applies thebrakes, a text message will be displayed in theinstrument panel.

City Safety warning level settings
City Safety is always activated but the function'swarning distance can be adjusted.
NOTE
City Safety cannot be turned off and activatesautomatically each time the engine/electricmotor is started.

Setting a warning level (distance)
The distance set for warnings determines thesystem'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 Topview.
2.Tap My CarIntelliSafeCity Safety.
3.Choose among Earlier, Normal or Later.
Begin by choosing Earlier. If too many warningsare given, change to Normal.
If the driver feels that warnings are given toooften, 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 exceptionalcircumstances, e.g., for a more dynamic drivingstyle.
WARNING
•No automatic system can be guaranteedto 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 beenselected, warnings may be perceived asbeing 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 aspossible, always using the setting Earlieris recommended.

NOTE
•Due to local traffic regulations in certainmarkets, RCW will not activate the rearturn signals. That part of the function willbe deactivated.
•The use of the rear turn signals will alsobe deactivated if the City Safety warninglevel is set at Later. See also the section"Setting a warning level (distance)" in thearticle "City Safety settings."
•If RCW detects a vehicle approachingfrom behind, the seat belt pretensioners

Detecting obstructions with CitySafety
City Safety can detect vehicles, cyclists, largeanimals and pedestrians.

Vehicles
City Safety detects most types of vehicles thatare 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 indarkness, its headlights and taillights must be onand clearly visible.

Cyclists
Optimal example of what the system considers to be acyclist: clear body/bike contours
To help function optimally, City Safety's functionfor 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 supplementarydriving aid and cannot detect all cyclists in allsituations, such as:
•a partially obscured cyclist.
•a cyclist whose clothing prevents a clearview of the person's body contours.
•a cyclist transporting a large object.
The driver is always responsible for operatingthe vehicle in a safe manner.

Pedestrians
Optimal example of what the system considers to be apedestrian: clear body contours
To help function optimally, City Safety's functionfor 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 acontrast 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 supplementarydriving 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 operatingthe 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 fordetecting 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 thecamera, the system cannot detect this animal.
City Safety can also help detect large animals indark conditions if they are in the path of the vehi-cle's headlights.
