Change of target and automatic braking with Pilot Assist *
In combination with automatic gearbox, Pilot Assist has functionality for change of target and braking at certain speeds.
Change of target
If the target vehicle in front suddenly turns then there may be stationary traffic in front.
When Pilot Assist is following another vehicle at speeds below 30 km/h (20 mph) and changes
target from a moving to a stationary vehicle, Pilot Assist will slow down for the stationary vehicle.
WARNING
When Pilot Assist is following another vehicle at speeds in excess of approx. 30 km/h
(20 mph) and the target is changed from a moving vehicle to a stationary vehicle, PilotAssist will ignore the stationary vehicle andinstead select the stored speed.
• The driver must then intervene him/ herself and brake.
Automatic standby mode with change of target
Pilot Assist is disengaged and set in standby mode: •when the speed is below 5 km/h (3 mph) and Pilot Assist is uncertain whether the tar-get object is a stationary vehicle or someother object, e.g. a speed bump.
• when the speed is below 5 km/h (3 mph)and the vehicle in front turns off so the PilotAssist no longer has a vehicle to follow.
Automatic brakingFor shorter stops in connection with inching for-ward in slow traffic or at traffic lights, driving isautomatically resumed if the stops do not exceedabout 3 seconds - if it takes longer before thecar in front starts moving again then the PilotAssist is set in standby mode with automaticbraking.
–Pilot Assist is reactivated in the following way:
• Press the steering wheel button
.
• Depress the accelerator pedal.
> Pilot Assist resumes following the vehicle ahead if it starts moving forward within 6 seconds.
NOTE
Pilot Assist can hold the car stationary for a maximum of 5 minutes - then the parkingbrake is applied and the function is disen-gaged. Before Pilot Assist can be reactivated, the parking brake must be released.

IMPORTANT
In certain situations, Pilot Assist steering assistance may have difficulty helping thedriver in the right way or it may be automati-cally deactivated - in which case, the use ofPilot Assist is not recommended. Examples ofsuch situations may be that: •the lane markings are worn, missing or cross each other.
• lane division is unclear, for example, whenthe lanes divide or merge or at exits or inthe event of multiple sets of markings.
• edges or other lines than lane markingsare present on or near the road, e.g.curbs, joints or repairs to the road sur-face, edges of barriers, roadside edges orstrong shadows.
• the lane is narrow or winding.
• the lane contains ridges or holes.
• weather conditions are poor, e.g. rain,snow or fog or slush or impaired viewwith poor light conditions, back-lighting,wet road surface etc.
The driver should also note that Pilot Assisthas the following limitations: • High kerbs, roadside barriers, temporary obstacles (traffic cones, safety barriers,etc.) are not detected. Alternatively, theymay be detected incorrectly as lane
markings, with a subsequent risk of con- tact between the car and such obstacles.The driver must ensure him/herself thatthe car is at a suitable distance from suchobstacles.
• The camera and radar sensor does nothave the capacity to detect all oncomingobjects and obstacles in traffic environ-ments, e.g. potholes, stationary obstaclesor objects which completely or partiallyblock the route.
• Pilot Assist does not "see" pedestrians,animals, etc.
• The recommended steering input is forcelimited, which means that it cannotalways help the driver to steer and keepthe car within the lane.
The driver always has the possibility of correcting or adjusting a steering intervention imposed byPilot Assist and can turn the steering wheel tothe desired position.
Steep roads and/or heavy loadBear in mind that Pilot Assist is primarilyintended for use when driving on level road surfa-ces. The function may have difficulty in keepingthe correct distance from the vehicle ahead whendriving on steep downhill slopes - in which case,be extra attentive and ready to brake. Do not usePilot Assist with a heavy load or with a trailer con-nected to the car.
Miscellaneous
•Off Road drive mode cannot be selected
when Pilot Assist is activated.
NOTE
The function uses the car's camera unit, which has some general limitations, see the"Limitations for camera unit" section.
NOTE
The function uses the car's radar unit, which has some general limitations, see the "Limita-tions for radar unit" section.

Limitations of Driver Alert Control
The Driver Alert Control (DAC) function may have limitations in certain situations.
In some cases, driving behaviour may not be affected, despite the driver being tired - e.g. whenusing the Pilot Assist function - with the resultthat the driver is then not given a warning fromDAC. For this reason, it is always very importantto stop and take a break in the event of theslightest sign of driver fatigue, regardless ofwhether DAC has given a warning. In some cases the system may issue a warning despite driving ability not deteriorating, for exam-ple:
• in strong side winds
• on rutted road surfaces.
NOTE
The function uses the car's camera unit, which has some general limitations, see the"Limitations for camera unit" section.

Lane Keeping Aid
The function of lane assistance is to help the driver to reduce the risk of the car accidentallyleaving its own lane on motorways and similarmajor routes.
Lane assistance steers the car back into its lane and/or warns the driver with an acoustic signal orsteering wheel vibration. Lane Keeping Aid is active within the speed range 65-200 km/h (40-125 mph) on roads withclearly visible side lines. On narrow roads the function may be unavailable, in which case it goes into standby mode. Thefunction becomes available again when the roadis wide enough.
A camera reads the side lines of the road/lane.

Lane assistance steers the car back into its lane.
Lane assistance warns with steering wheel vibrations23
.
Depending on settings, lane assistance acts in accordance with the following:
1. Steering assistance activated: When the car
is approaching a lane line, LKA will actively steer the car back into its lane by applying a slight torque to the steering wheel.
2. Warning activated: If the car is about to cross a lane line, the driver is warned by means ofan acoustic signal or vibration in the steeringwheel.
NOTE
When a direction indicator is switched on, there are no steering corrections or alertsfrom Lane assistance.
WARNING
Lane assistance is merely a driver aid and does not engage in all driving situations ortraffic, weather or road conditions. The driver always bears ultimate responsibility for ensuring that the vehicle is driven safelyand that applicable laws and road traffic regu-lations are followed.

Park assist lines and fields for the Park Assist Camera *
The Park Assist Camera indicates the position of the car in relation to its surroundings by display-ing lines on the camera image.
Park assist lines
Examples of how the park assist lines can be displayed for the driver.
Park assist lines show the intended route for the car's external dimensions with the current steer-ing wheel angle - this facilitates parallel parking,reversing into tight spaces and when connectinga trailer. The lines on the screen are projected as if they were at ground level behind the car and responddirectly to steering wheel movements, showingthe driver the path the car will take - also whenthe car is turning. These park assist lines include the car's mostprotruding parts, e.g. towbar, door mirrors andcorners.
NOTE
Park assist lines are not shown when zoom- ing in.
NOTE
•
When reversing with a trailer which is not connected electrically to the car, the lines on the display show the route the
car will
take - not the trailer.
• The screen shows no lines when a trailer is connected electrically to the car's elec-trical system.
IMPORTANT
Remember that when rear camera view is selected, the centre display only shows thearea behind the car. Keep an eye on the sidesand front of the car when turning the steeringwheel while reversing. The same applies vice versa - note what hap- pens to the rear parts of the car when thefront camera view is selected. Note that the guide lines show the
shortest
route. Therefore, pay extra attention to the car's sides so that they do not go against/over something when the steering wheel isturned when driving forward or that the frontsweeps against/over something when thesteering wheel is turned when reversing.

Park Assist Pilot *
Active parking assistance (Park Assist Pilot - PAP) helps the driver to park in or leave a park-ing space.
PAP checks first if a space is sufficiently big and thereafter helps the driver to turn the steeringwheel and manoeuvre the car into the space. The centre display indicates with symbols, graph- ics and text the various operations to be carriedout and when to do so.
NOTE
The PAP function measures the space and steers the car - the driver's task is to:
• keep a close watch around the car
• follow the instructions in the centre dis-play
• change gear (reverse/forward)
• control and maintain a safe speed
• brake and stop.

NOTE
PAP searches the area for parking, displays instructions and guides the car in on its pas-senger side. But if required the car can alsobe parked on the driver's side of the street: •Activate the direction indicator to the driver's side - then the system searchesfor a parking space on that side of thecar instead.
Reversing in to the parking space
Parallel.
Perpendicular.
1. Check that there is nothing behind.
2. Reverse slowly and carefully without touching
the steering wheel - and no faster than 7 km/h (4 mph).
> PAP will then steer the car into the park-ing space.
3. Keep an eye on the centre display - be pre- pared to stop the car when the graphics and message so request.
NOTE
• Keep your hands away from the steering wheel when the PAP function is acti-vated.
• Make sure that the steering wheel is nothindered in any way and can rotate freely.
• To achieve optimum results - wait untilthe steering wheel is fully turned beforestarting to drive backward/forward.
