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.
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.
The driver can always correct or adjust steer-ing assistance provided by Pilot Assist by turn-ing the steering wheel to the desired position.
Steep roads and/or heavy loadsPilot Assist is primarily intended to be drivenon flat roads. The function may not be able tomaintain the correct time interval to the vehi-cle ahead when driving down steep hills. Thedriver should be extra attentive and preparedto apply the brakes.
Other limitationsThe Off Road drive mode cannot be selected
when Pilot Assist is activated.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain generallimitations.

A number of symbols and messages relating to Pilot Assist may be displayed in the instru- ment panel and/or the head-up display *.
In the following illustration, Road Sign Infor- mation (RSI 43
) indicates that the maximum
permitted speed is 130 km/h (80 mph).
The previous illustration shows that Pilot Assist is set to maintain a speed of 110 km/h(68 mph) and that there is no target vehicleahead to follow. Pilot Assist will not provide any steering assis- tance because it cannot detect the lane's sidemarking lines.

Collision risk warning from driver support
The driver support systems Adaptive Cruise Control * and Pilot Assist * can help alert the
driver if the distance to the vehicle ahead suddenly decreases to an unsafe distance.
Collision warning audible signal and symbol.
Acoustic collision warning signal
Collision warning symbol
Camera/radar sensor distance monitoring
Adaptive Cruise Control and Pilot Assist use approx. 40% of the braking capacity. If a sit-uation requires more braking force than driversupport can provide, and if the driver does not apply the brakes, a warning light and audible warning signal will be activated to alert thedriver that immediate action is required.
WARNING
The driver support system only issues a warning for vehicles detected by its radarunit – thus, a warning may come after adelay or not at all. Never wait for a warning.Apply the brakes when necessary.
Collision warning symbol on the windshield.
In vehicles equipped with a head-up display *,
a flashing warning symbol will be displayed on the windshield.
NOTE
Visual warnings on the windshield may be difficult to notice in cases of strong sun-light, reflections, extreme light contrasts,or if the driver is wearing sunglasses or isnot looking straight ahead.

Passing assistance Passing assistance can assist the driver when passing other vehicles. The function can be used with Adaptive Cruise Control * or Pilot
Assist *.
How passing assistance worksWhen Adaptive Cruise Control or Pilot Assist is following another vehicle and you indicatethat you intend to pass that vehicle by using the turn signal 47
, the system will begin accel-
erating toward the vehicle ahead before your
vehicle has moved into the passing lane. The function will then delay a speed reduction to avoid early braking as your vehicleapproaches a slower-moving vehicle. The function remains active until your vehicle has passed the other vehicle.
WARNING
Please note that this function can be acti- vated in more situations than just passinganother vehicle, such as when a directionindicator is used to indicate a lane changeor before exiting to another road – the vehi-cle will then briefly accelerate.
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.

Using passing assistance Passing assistance can be used with Adap- tive Cruise Control * or Pilot Assist *. Several
conditions must be met for passing assis- tance to be possible.
In order to activate passing assistance:
your vehicle must be following a vehicle ahead (target vehicle)
your vehicle's
current speed must be
at least 70 km/h (43 mph)
the set speed
must be high enough to
safely pass another vehicle.
To start passing assistance:
–Turn on the left turn signal.
> Passing assistance will start.
47 Only the left-hand turn signal for left-hand drive vehicles, or right-hand turn signal for right-hand drive vehicles.

WARNING
The driver should be aware that if condi- tions suddenly change when using PassingAssistance, the function may implement anundesired acceleration in certain condi-tions. Some situations should be avoided, e.g. if: the vehicle is approaching an exit in the same direction as passing would nor-mally occur
the vehicle ahead slows before yourvehicle has had time to switch to thepassing lane
traffic in the passing lane slows down
Situations of this type can be avoided by tem-porarily putting Adaptive Cruise Control or
Pilot Assist in standby mode.

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

Automatic braking during delayed evasive maneuvers with CitySafety
City Safety 56
can assist the driver by auto-
matically braking the vehicle when it is not possible to avoid a collision by steering alone.
City Safety assists the driver by periodically attempting to predict possible "escaperoutes" to the sides of the vehicle in the eventa slow-moving or stationary vehicle were to bedetected at a late stage.
Your vehicle (1) cannot detect any potential escape routes for veering away from the vehicle ahead (2)and may therefore apply the brakes at an earlierstage.
Own vehicle
Slow-moving/stationary vehicles City Safety will not intervene to automatically apply the brakes if it is possible for the driverto avoid a collision by steering the vehicle. However, if City Safety determines that an evasive maneuver would not be possible dueto traffic in the adjacent lane(s), the functioncan assist the driver by automatically startingto apply the brakes at an earlier stage.
