Electronic Stability Control
The Electronic Stability Control (ESC 1
) func-
tion helps the driver avoid skidding and improves the vehicle's directional stability.
This symbol will be displayed in the instrument panel whenthe system is intervening. When the system has inter- vened to apply the brakes, apulsing sound may be heard
and the vehicle may accelerate more slowlythan expected when the accelerator pedal isdepressed.
The system consists of the following sub-func- tions:
Stability control 2
Spin control and active yaw control
Engine drag control
Trailer Stability Assist
WARNING
The function is supplementary driver support intended to facilitate drivingand help make it safer – it cannot han-dle all situations in all traffic, weatherand road conditions.
The driver is advised to read all sec-tions in the Owner's Manual about thisfunction to learn of its limitations,which the driver must be aware ofbefore using the function.
Driver support functions are not a sub-stitute for the driver's attention andjudgment. The driver is always respon-sible for ensuring the vehicle is drivenin a safe manner, at the appropriatespeed, with an appropriate distance toother vehicles, and in accordance withcurrent traffic rules and regulations.
Stability control 2This function helps control the driving andbraking force of each individual wheel in anattempt to stabilize the vehicle.

Electronic Stability Control in sport mode The stability system (ESC 6
) is always acti-
vated and cannot be switched off. However, the driver can select
ESC Sport Mode,
which offers more active driving characteris- tics.
With the ESC Sport Mode sub-function
selected, intervention from the system is reduced and more lateral movement is permit-ted, giving the driver more control of the vehi-cle than usual. When
ESC Sport Mode is selected, the func-
tion may seem to be disabled even though it continues to assist the driver.
NOTE
When ESC Sport Mode is selected, the
trailer stabilizer (TSA 7
) is switched off.
ESC Sport Mode also helps provide more
traction, even if the vehicle gets stuck or is driving on a loose surface such as deep snowor loose sand.

limitations
Adaptive Cruise Control (ACC 31
) may have
limited functionality in certain situations.
Steep roads and/or heavy loadsAdaptive Cruise Control is primarily intended to be driven on flat roads. The function maynot be able to maintain the correct time inter-val to the vehicle ahead when driving downsteep hills. The driver should be extra attentiveand prepared to apply the brakes. Do not use Adaptive Cruise Control if the vehi- cle is carrying a heavy load or towing a trailer.
Other limitationsThe Off Road drive mode cannot be selected
if Adaptive Cruise Control is activated.
WARNING
This is not a collision avoidance sys- tem. The driver is always responsibleand must intervene if the system failsto detect a vehicle ahead.
The function does not brake for peopleor animals and does not brake for smallvehicles, such as bikes and motorcy-cles. Similarly, it does not brake for lowtrailers, oncoming, slow-moving or sta-tionary vehicles and objects.
Do not use the function in demandingsituations, such as in city traffic, atintersections, on slippery surfaces,with a lot of water or slush on the road,in heavy rain/snow, in poor visibility, onwinding roads, or on on/off ramps.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain generallimitations.

tively, they may be detected incorrectly as lane markings, with a subsequentrisk of contact between the vehicle andsuch obstacles. The driver is responsi-ble for ensuring that the vehicle main-tains a suitable distance from suchobstacles.
The camera and radar sensors do nothave the capacity to detect all oncom-ing objects and obstacles in trafficenvironments, e.g. potholes, stationaryobstacles or objects that completely orpartially block the route.
Pilot Assist does not "see" pedestrians,animals, etc.
The recommended steering input islimited in force, which means that itcannot always help the driver to steerand keep the vehicle within the lane.
In vehicles equipped with Sensus Navigation
*, the function is able to use
information from map data, which could cause variations in performance.
Pilot Assist will be switched off if thespeed-dependent power steeringwheel resistance is working at reducedpower, e.g. during cooling due to over-heating.WARNING
Pilot Assist should only be used if there are clear lane lines painted on each side of thelane. All other use will increase the risk ofcontact with nearby obstacles that cannotbe detected by the functions.

Limited field of vision
The radar sensor has a limited field of vision. In some situations, it may detect a vehicle laterthan expected or not at all.
The radar sensor's field of vision.
The radar sensor's detection of vehicles very close to your vehicle may be delayedin certain situations, e.g. if a vehicle pulls in between your vehicle and the vehicledirectly ahead.
Small vehicles, such as motorcycles, or vehicles that are not driving in the centerof the lane may remain undetected.
In curves, the radar may detect the wrong vehicle or lose sight of a target vehicle.
Low trailers
Low trailer in the radar shadow.
Low trailers may also be difficult or even impossible for the radar to detect. The driver should be extra alert when driving behind vehi- cles towing low trailers when Adaptive Cruise Control
* or Pilot Assist * is activated.
Camera
Reduced visibility
Cameras have the same limitations as the human eye. In other words, their “vision" isimpaired by adverse weather conditions suchas heavy snowfall/rain, dense fog, swirlingdust/snow, etc. These conditions may reduce the function of systems that depend on thecamera or cause these systems to temporarilystop functioning. Strong sunlight, reflections from the road sur- face, ice or snow covering the road, a dirtyroad surface, or unclear lane marker lines maydrastically reduce the camera

Blind sectors
There are "blind" sectors between the cameras' fields of vision.
With Park Assist Camera's 360° view *
selected, objects/obstacles may not be detected if they are located in the "joints"where the edges of the individual cameraviews meet.
WARNING
Even if it seems as though only a fairly small section of the screen image isobstructed, this may mean that a relativelylarge sector is hidden and obstacles theremay not be detected until they are verynear the vehicle.
Defective camera
If a camera sector is dark and contains this symbol, thisindicates that the camera isnot functioning properly. See the following illustration for an example.
The vehicle's left-side camera is malfunctioning.
A dark camera sector may also be displayed in the following situations, but without the
defective camera symbol: a door is open
the tailgate is open
a rearview mirror is folded in
Lighting conditions
The camera image is automatically adjusted according to the current lighting conditions.This means that the brightness and quality of the image may vary slightly. Poor lighting con-ditions may result in reduced image quality.
Rear Park Assist Camera
WARNING
Be extra cautious when reversing if this symbol isshown when a trailer, bikecarrier or similar isattached and electricallyconnected to the vehicle. The symbol indicates that
the rear parking assist sensors are deacti-
vated and will not warn of any obstacles.
NOTE
A bike carrier and other accessories moun- ted on the rear of the vehicle can obscurethe camera's view.

Rear Collision Warning *63
The Rear Collision Warning 64
(RCW) function
can help the driver avoid rear-end collisions from vehicles approaching from behind.
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 function detects that the vehicle is in dangerof being hit from behind, the seat belt tension-ers may tension the front seat belts. TheWhiplash Protection System will also be acti-vated in a collision. Immediately before a collision from behind, the function may also activate the brakes inorder to reduce the forward acceleration of thevehicle during the collision. However, thebrakes will only be applied if your vehicle isstationary. The brakes will be immediatelyreleased if the accelerator pedal is depressed. The function is automatically activated each time the engine is started.
WARNING
The function is supplementary driver support intended to facilitate drivingand help make it safer – it cannot han-dle all situations in all traffic, weatherand road conditions.
