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.

BLIS
*
The BLIS 62
function is designed to help pro-
vide assistance in heavy traffic with several lanes moving in the same direction by helpingthe driver to detect the presence of vehiclesin the "blind spot" area behind and to the sideof the vehicle.
Location of BLIS indicator light.
BLIS is a driver support system designed to alert the driver of:
vehicles in your "blind spot"
vehicles approaching rapidly in adjacentlanes.
BLIS overview
Blind spot zone
Rapidly approaching vehicle zone.
The system is designed to react to:
vehicles passing your vehicle
vehicles that are rapidly approaching your vehicle from behind.
When BLIS detects a vehicle in zone 1 or arapidly approaching vehicle in zone 2, an indi-cator light will illuminate in the relevant rear-view mirror and glow steadily. If the driverthen uses the turn signal on the side in whichthe warning has been given, the indicator lightwill become brighter and begin flashing. BLIS is active when your vehicle is traveling at a speed over 10 km/h (6 mph).

Driver Alert Control limitations
Driver Alert Control (DAC) functionality may be reduced in certain situations.
In certain situations, the system may provide a warning even if it has not detected a change indriving behavior, e.g.: in strong crosswinds
on grooved road surfaces.
WARNING
In certain cases, driving behavior might not be affected despite the driver's fatigue – when using the Pilot Assist
* function –
resulting in the driver not getting a warning from DAC. It is therefore very important to always stop and take a break at the slightest signof fatigue, regardless of whether the func-tion has issued a warning or not.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain generallimitations.

Lane Keeping Aid
Lane Keeping Aid (LKA 85
) is designed to
actively steer the vehicle on freeways, high- ways and other major roads to help the driverreduce the risk of the vehicle unintentionallyveering out of the lane.
Lake Keeping Aid steers the vehicle back into the lane and/or alerts the driver using vibra-tions in the steering wheel. Lane Keeping Aid is active at speeds between 65–200 km/h (40–125 mph) on roads withclearly visible traffic lane marker lines. On narrow roads, the function may be unavail- able and go into standby mode. The functionwill become available again when the roadbecomes sufficiently wide.
A camera monitors the road/traffic lane's marker lines.

Lane Keeping Aid alerts the driver using vibrations in the steering wheel.
Depending on the settings used, Lane Keep- ing Aid functions in different ways:
Assist enabled: When the vehicle
approaches a lane marker line, the func- tion will actively steer the vehicle back intothe lane using light pressure on the steer-ing wheel.

Warning enabled: If the vehicle is about
to move over a lane marker line, the driver will be alerted by vibrations in the steeringwheel.
There is also an option for activating steeringassistance and alerts at the same time.
NOTE
When the direction indicators/turn signals are activated, the Lane Keeping Aid doesnot provide any warning or intervene withsteering.
