The function may have limited functionality incertain situations and not intervene, e.g.:
for smaller vehicles such as motorcycles
on roads that do not have clear lane mark-ings
if more than half of your vehicle has movedinto the adjacent lane
outside the speed range 60-140 km/h(37-87 mph)
when the power steering works at reducedpower - e.g. during cooling due to overheat-ing (see section "Speed-dependent steeringforce").
Functionality may also be reduced in other situa-tions, such as:
road work
winter driving conditions
narrow roads
poor road surfaces
a very sporty driving style
bad weather with reduced visibility.
In these demanding driving conditions, the func-tion may not be able to properly assist the driver.
In these situations, it is recommended that it isturned off.

NOTE
The function uses the vehicle's combinedcamera and radar unit, which has certain gen-eral limitations; see sections "Camera limita-tions" and "Radar sensor limitations".

Steering assistance during collision
risks from behind*
If you become distracted and do not notice yourvehicle starting to veer out of the lane whileanother vehicle is approaching from behind or isin your vehicle's blind spot, this sub-function canhelp provide assistance.
The function provides assistance by steering your vehi-cle back into your own lane.
Another vehicle in blind spot zone
Own vehicle
If your vehicle is beginning to veer out of yourlane while another vehicle is in your blind spot oranother vehicle is rapidly approaching in the nextlane, this function can help the driver steer thevehicle back into its own lane.
Even if the driver intentionally changes lanesusing a turn signal without noticing another vehi-
cle approaching, the function can provide assis-tance.
The function is active at speeds between60-140 km/h (37-87 mph) on roads with clearlyvisible traffic lane markings/lines.
After the system has automatically intervened,this text message will appear in the instrumentpanel:
Collision avoidance assistance –Automatic intervention

WARNING
The "Steering assistance at risk of rear-end collision" subfunction is supplemen-tary driver support intended to improvedriving safety – it cannot handle all situa-tions in all traffic, weather and road condi-tions.
Pilot Assist is only activated if there is ahigh risk of collision – you must thereforenever wait for the function to intervene.
The function is not a substitute for thedriver's attention and judgment. The driveris always responsible for ensuring thevehicle is driven in a safe manner, at theappropriate speed, with an appropriatedistance to other vehicles, and in accord-ance with current traffic rules and regula-tions.

Side sensors
Rapid pulsing warning signal when the obstacle is lessthan approx. 25 cm (0.8 ft) from the vehicle 107.
Park Assist's side sensors are automatically acti-vated when the engine is started. They are activeat speeds below 10 km/h (6 mph).
The distance monitored is approx. 25 cm (0.8 ft)out from the sides.
The detection area increases significantly whenthe steering angle of the front wheels increasesand depending on the steering wheel position,obstacles up to approx. 90 cm (3 ft) directlybehind or in front of the vehicle can be detected(also see “Side sensor fields” in the section “Sen-sor field from Park Assist for Park Assist Cam-era”).

Park Assist Camera trajectory lines
The Park Assist Camera uses trajectory linesand fields on the screen to indicate the vehicle'sposition in relation to its immediate surround-ings.
Example114 of trajectory lines.
The trajectory lines show the anticipated trajec-tory for the vehicle's outermost dimensions basedon the current position of the steering wheel to
help simplify parallel parking, backing into tightspaces or attaching a trailer.
The lines on the screen are projected as if theywere painted lines on the ground behind thevehicle and are directly affected by the way inwhich the steering wheel is turned. This enablesthe driver to see path the vehicle will take, even ifhe/she turns the steering wheel.
These lines also indicate the outermost limits thatany object (towbar, rearview mirrors, corners ofthe body, etc.) extends out from the vehicle.

NOTE
When reversing with a trailer that is notelectrically connected to the vehicle, thescreen guide lines show the path thevehicle will take – not the trailer.
The screen does not show guide lineswhen a trailer is electrically connected tothe vehicle's electrical system.
Guide lines are not shown when zoomingin.
CAUTION
Bear in mind that when the rearwardcamera view is selected, the screen onlyshows the area behind the vehicle – payattention to the sides and front of thevehicle when steering while reversing.
The same applies to the reverse – payattention to what is happening with therear parts of the vehicle when the frontcamera view is selected.
Note that the guide lines show the short-est path – pay extra attention to ensurethat the vehicle sides do not come incontact with/travel over anything whensteering while driving forward or that thevehicle front moves toward/over anythingwhen steering while reversing.

Sensor field from Park Assist forPark Assist Camera
If the vehicle is equipped with Park Assist, dis-tances will be shown in the 360° view with col-ored fields for each sensor that has detected anobstacle.

Front and rear sensors
The screen can display colored sensor fields on thevehicle symbol115.
The front and rear fields change colors (fromYELLOW to ORANGE to RED) as the vehiclemoves closer to an obstacle.
Field color rear-wardDistance in meters (feet)
Yellow0.6-1.5 (2.0-4.9)
Orange0,3–0,6 (1,0–2,0)
Red0-0.3 (0-1.0)
Field color forward Distance in meters (feet)
Yellow0,6–0,8 (2,0–2,6)
Orange0,3–0,6 (1,0–2,0)
Red0-0.3 (0-1.0)
When the sensor field color is red, the audiblepulsing sounds will change to a continuous tone.

Side sensor fields
Warning signals vary depending on the vehicle'sintended direction of travel. Depending on thesteering wheel position, warnings may be givenfor obstacles diagonally in front of or behind thevehicle, not only directly behind the vehicle.
Parking sensor sectors where obstacles can bedetected115.
Left-side front sensor field
Obstacle sector in the vehicle's intendeddirection of travel forward – varies accordingto steering wheel position
Sector with RED field color and rapidly puls-ing tone
Right-side rear sensor field
Obstacle sector in the vehicle's intendeddirection of travel rearward – varies accordingto steering wheel position.
