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.

Switching target vehicles with driver support
At certain speeds, vehicles with automatic transmissions and the driver support func- tions Adaptive Cruise Control * and Pilot
Assist * can switch target vehicles.
Switching target vehicles
If the target vehicle ahead turns suddenly, there may be stationary traffic ahead.
When driver support is actively following another vehicle at speeds under 30 km/h
(20 mph) and switches targets from a movingvehicle to a stationary vehicle, driver supportwill brake for the stationary vehicle.
WARNING
When driver support follows another vehi- cle at speeds over approx. 30 km/h
(20 mph) and changes target vehicle –from a moving vehicle to a stationary one –driver support will ignore the stationary
vehicle and instead accelerate to the storedspeed. The driver must then intervene and apply the brakes.
Automatic standby mode when switching targets
Driver support disengages and goes into standby mode if:
your vehicle's speed goes under 5 km/h(3 mph) and driver support cannot deter-mine if the target vehicle is stationary or ifit is another object, e.g. a speed bump.
your vehicle's speed goes under 5 km/h(3 mph) and the vehicle ahead turns sothat driver support no longer has a vehicleto follow.

Setting time interval to the vehicle ahead The time interval to the vehicle ahead can be set for the functions Adaptive Cruise Control *,
Pilot Assist * and Distance Alert *.
Different time intervals to the vehicle ahead can be selectedand are shown in the instru-ment panel as 1–5 horizontalbars. The more bars, thelonger the time interval. Onebar represents an interval of
approx. 1 second to the vehicle ahead. 5 barsrepresents approx. 3 seconds.
NOTE
When the symbol in the instrument panel shows a vehicle and a steering wheel, PilotAssist follows a vehicle ahead at a presettime interval. When only a steering wheel is shown, there is no vehicle ahead within a reasona-ble distance.
NOTE
When the symbol in the instrument panel shows two vehicles, ACC is following thevehicle ahead at a preset time interval. When only one vehicle is shown, there is no vehicle ahead within a reasonable dis-tance.
Controls for setting a time interval.
Reduce the time interval
Increase the time interval
Distance indicator
–Press the (1) or (2) button to decrease or increase the time interval.
> The distance indicator (3) shows the current time interval. In order to help your vehicle follow the vehicle ahead as smoothly and comfortably as possi-ble, Adaptive Cruise Control allows the timeinterval to vary noticeably in certain situations.At low speeds, when the distance to the vehi-cle ahead is short, Adaptive Cruise Controlincreases the time interval slightly.
NOTE

The greater the vehicles' speed, the greater the distance between them fora set time interval.
Only use the time intervals permittedby local traffic regulations.
If driver support does not seem torespond with a speed increase whenactivated, it may be because the timeinterval to the vehicle ahead is shorterthan the set time interval.
WARNING
Only use a time interval suitable for the current traffic conditions.
The driver should be aware that shorttime intervals give them limited time toreact and act to any unforeseen trafficsituation.

Auto-hold braking with driver support
The driver support functions Adaptive Cruise Control * and Pilot Assist * have a special brake
function in slow traffic and while stationary.
Braking function in slow traffic and at a standstill
In slow-moving, stop-and-go traffic or when stopped at a traffic light, driving will resumeautomatically if the vehicle is stopped for lessthan approx. 3 seconds. If it takes more than 3seconds for the vehicle ahead to begin movingagain, the driver support function will go intostandby mode and the auto-hold brake func-tion will activate.
–The function can be reactivated by:
Pressing the
button on the steer-
ing wheel keypad.
Pressing the accelerator pedal.
> The function will resume following the vehicle ahead if it begins to move within approx. 6 seconds.
WARNING
A noticeable increase in speed may follow when the speed is resumed with the
steering wheel button.
WARNING
The driver support system only issues a warning for obstacles detected by its radarsensor – thus, a warning may come after adelay or not at all.
Never wait for a warning or assistance. Apply the brakes when necessary.
NOTE
Driver support can keep the vehicle sta- tionary for no more than 5 minutes – afterthat time the parking brake is applied andthe function is deactivated. The parking brake must be released before driver support can be reactivated.

Curve Speed Assist (CSA) *44
Curve Speed Assist can help the driver
reduce speed before sharp turns if the preset speed for the driver support function Adap- tive Cruise Control * or Pilot Assist * is deter-
mined to be too high.
This assessment is performed using informa- tion from map data in the vehicle's navigation system, Sensus Navigation *. After the turn,
the vehicle will resume the previously set speed.
As the function reduces thevehicle's speed, this symbolwill be displayed in the instru-ment panel.
The driver can cancel the function at any time by braking or using the accelerator pedal.
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.
Drive modes
Cornering assistance varies depending on the selected drive mode. If drive mode cannot be selected, the function will use the
Comfortoption. In Dynamic mode, cornering will be
sporty, with slightly more powerful accelera- tion coming out of curves.

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 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.

Park Assist 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 trunk lid 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
NOTE
A bike carrier and other accessories moun- ted on the rear of the vehicle can obscurethe camera's view.
