Limited field of vision
The radar sensor has a limited field of vision. Insome situations, it may detect a vehicle later thanexpected or not at all.
The radar sensor's field of vision.
The radar sensor's detection of vehicles veryclose to your vehicle may be delayed in cer-tain situations, e.g. if a vehicle pulls in
between your vehicle and the vehicle directlyahead.
Small vehicles, such as motorcycles, or vehi-cles that are not driving in the center of thelane may remain undetected.
In curves, the radar may detect the wrongvehicle or lose sight of a target vehicle.
Low trailers
Low trailer in the radar shadow.
Low trailers may also be difficult or even impossi-ble for the radar to detect. The driver should beextra alert when driving behind vehicles towinglow trailers when Adaptive Cruise Control or PilotAssist is activated.
Camera
Reduced visibility
Cameras have the same limitations as the humaneye. In other words, their “vision" is impaired byadverse weather conditions such as heavy snow-fall/rain, dense fog, swirling dust/snow, etc.These conditions may reduce the function of sys-
tems that depend on the camera or cause thesesystems to temporarily stop functioning.
Strong sunlight, reflections from the road surface,ice or snow covering the road, a dirty road sur-face, or unclear lane marker lines may drasticallyreduce the camera

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.

Rear Collision Warning51
The Rear Collision Warning52 (RCW) functioncan help the driver avoid rear-end collisions fromvehicles approaching from behind.
The function is automatically activated each timethe engine is started.
The function can alert drivers of following vehi-cles of the risk of a collision by rapidly flashingthe turn signals.
If, at a speed below 30 km/h (20 mph), the func-tion detects that the vehicle is in danger of beinghit from behind, the seatbelt tensioners may ten-sion the front seat belts and activate theWhiplash Protection System safety system.
Immediately before a collision from behind, thefunction may also activate the brakes in order toreduce the forward acceleration of the vehicleduring the collision. However, the brakes will onlybe applied if your vehicle is stationary. The brakeswill be immediately released if the acceleratorpedal is depressed.

Rear Collision Warning53 limitations
In some situations, it may be difficult for RearCollision Warning (RCW) to warn the driver of acollision risk.
This may be the case if:
the vehicle approaching from the rear isdetected at a late stage
the vehicle approaching from the rearchanges lanes at a late stage
a trailer, bicycle holder or similar is con-nected to the vehicle's electrical system - thefunction will then be automatically deacti-vated.
NOTE
In certain markets RCW does not warn withthe direction indicators due to local trafficregulations – in such cases, that part of thefunction is deactivated.
NOTE
The warning with direction indicators for RearCollision Warning is deactivated if the colli-sion warning distance in the City Safety func-tion is set to the lowest level "Late".
The seat belt tensioning and braking func-tions remain active.

BLIS limitations
BLIS57 functionality may be reduced in certainsituations.
Keep the marked area clean (on both the left and rightsides of the vehicle)58.
Examples of limitations:
Dirt, ice and snow covering the sensors mayreduce functionality and prevent the systemfrom providing warnings.
The BLIS function is automatically deacti-vated if a trailer, bicycle holder or similar isconnected to the vehicle's electrical system.
For BLIS to function optimally, bicycle hold-ers, luggage racks or similar should not bemounted on the vehicle's towbar.
WARNING
BLIS does not work in sharp curves.
BLIS does not work when the vehicle isbeing reversed.
NOTE
The function uses the vehicle's camera andradar sensor, which has certain general limita-tions.

In a diagonal parking space, CTA may be completely"blind" on one side of your vehicle.
CTA's blind zone.
CTA's field of vision.
However, as you back your vehicle slowly out of aparking space, CTA's field of vision changes inrelation to the obstructing vehicle/object and itsblind zone is reduced.
Examples of further limitations
The auto brake sub-function only detectsvehicles in motion and may therefore not
"see" and brake for e.g. stationary obstacles,a cyclists or a pedestrian.
Dirt, ice and snow covering the sensors mayreduce functionality and prevent the systemfrom providing warnings.
CTA is automatically deactivated if a trailer,bicycle holder or similar is connected to thevehicle's electrical system.
For CTA to function optimally, bicycle hold-ers, luggage racks or similar should not bemounted on the vehicle's towbar.

Road Sign Information* limitations
Road Sign Information (RSI77) functionality maybe reduced in certain situations.
The function could have reduced functionalitydue to e.g.:
faded road signs
signs located in a curve in the road
twisted or damaged signs
signs positioned high above the road
fully/partially obstructed or poorly positionedsigns
signs partially or fully covered by frost, snowand/or dirt
digital road maps78 that are outdated, incor-
rect or do not contain speed information79.
NOTE
Certain types of bike carriers that are con-nected to the trailer socket may be interpre-ted as a connected trailer by the RSI function.In such cases, the instrument panel may indi-cate incorrect speed information.
NOTE
The function uses the vehicle's camera andradar sensor, which has certain general limita-tions.

Driver Alert Control
The Driver Alert Control (DAC) function isdesigned to help capture the driver becomeaware of erratic behavior, e.g. if the driver is dis-tracted or showing signs of fatigue.
The objective of DAC is to detect slowly deterio-rating driving behavior and is primarily intended tobe used on major roads. The function is notintended for use in city traffic.
DAC is activated when the vehicle's speedexceeds 65 km/h (40 mph) and remains activeas long as speeds are above 60 km/h (37 mph).
DAC detects the vehicle's position in the traffic lane.
