Cross Traffic Alert *
CTA 86
is a supplementary driver support system
to BLIS 87
that is intended to help the driver
detect vehicles crossing behind the vehicle while backing up.
CTA overview.
CTA supplements BLIS by detecting traffic cross- ing from the side, e.g. when backing out of aparking space. CTA is primarily designed to detect vehicles, but in certain cases can also detect pedestrians orsmaller objects such as bicycles. CTA is only active when the vehicle is moving backward or if reverse gear is engaged. If CTA detects that something is approachingyour vehicle from the side:
• an audible signal will sound from either theleft or right speaker, depending on whichside of your vehicle the object is approachingfrom.
• an icon will illuminate in the PAS 88
graphic
on the screen.
• an icon will appear in the Park Assist Cam-era's Top view.

Road Sign Information with speedcamera information
Vehicles equipped with RSI 102
and Sensus
Navigation * can provide information on upcom-
ing speed cameras in the instrument panel.
Speed camera information in the instrument panel 103
.
If the vehicle exceeds a detected speed limit with theSpeed Warning function acti-vated, the driver is given aspeed warning when the vehi-cle is approaching a speedcamera if the navigation map
for the vehicle's current location contains infor-mation on speed cameras.
For more information on Speed Warnings in con- junction with speed cameras, see "Road SignInformation with Speed Warning and settings"and "Road Sign Information limitations".
NOTE
• For an audible alert to be provided if the speed is exceeded, the Speed Limit
Warning function must be activated and
the Road Sign Audio Warning sub-
function must be On. Audible alerts are
provided if the vehicle's speed exceeds the speed displayed by RSI in the instru-ment panel.
• Information about speed cameras on thenavigation map is not available for allmarkets/areas.

The warnings will be repeated after a short time if driving behavior does not improve.
WARNING
•
The Driver Alert Control function is sup- plementary driver support intended tofacilitate driving and help make it safer –it cannot handle all situations in all traffic,weather and road conditions.
• Driver Alert Control must not be used toextend a period of driving. The drivershould plan in breaks at regular intervalsand make sure they are well rested.
• Driver Alert Control is not a substitute forthe driver's attention and judgment. Thedriver is always responsible for ensuringthe vehicle is driven in a safe manner, atthe appropriate speed, with an appropri-ate distance to other vehicles, and inaccordance with current traffic rules andregulations.
WARNING
An alarm from Driver Alert Control should be taken very seriously since a sleepy driver isoften not aware of their own condition. If the alarm sounds or you feel fatigued:
• Stop the vehicle safely as soon as possi- ble and rest.
Studies have shown that it is just as danger- ous to drive while tired as it is to drive underthe influence of alcohol or other stimulants.

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 – whenusing the Pilot Assist function – resulting inthe driver not getting a warning from DAC. It is therefore very important to always stop and take a break at the slightest sign of fati-gue, regardless of whether the DAC functionhas issued a warning or not.
NOTE
The function uses the vehicle's camera unit, which has some general limitations – see thesection "Camera unit limitations".

Lane Keeping Aid
Lane Keeping Aid (LKA 107
) is designed to
actively steer the vehicle on freeways, highways and other major roads to help the driver reducethe risk of the vehicle unintentionally veering outof the lane.
Lake Keeping Assistance 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 unavailable and go into standby mode. The function willbecome available again when the road becomessufficiently wide.
A camera monitors the road/traffic lane's marker lines.

Lane Keeping Aid alerts the driver using vibrations in the steering wheel108
.
Depending on the settings used, Lane Keeping Aid functions in different ways:
• With
Assist109
activated: When the vehicle
approaches a lane marker line, LKA will actively steer the vehicle back into the laneusing light pressure on the steering wheel.
• With
Warning109
activated: If the vehicle is
about to move over a lane marker line, the driver will be alerted by vibrations in thesteering wheel.
NOTE
When the direction indicator is activated, the Lane Keeping Aid does not provide any warn-ing or intervene with steering.
WARNING
• The Lane Keeping Aid function is supple- mentary driver support intended to helpimprove driving safety – it cannot handleall situations in all traffic, weather androad conditions.
• The function is not a substitute for thedriver's attention and judgment. The driveris always responsible for ensuring thevehicle is driven in a safe manner, at theappropriate speed, with an appropriatedistance to other vehicles, and in accord-ance with current traffic rules and regula-tions.

Run-Off Mitigation with steeringassistance
This sub-function is intended to help reduce the risk of the vehicle inadvertently running off theroad by actively steering the vehicle back ontothe road.
The function is active at speeds between 65-140 km/h (40-87 mph) on roads with clearlyvisible traffic lane markings/lines. The system uses a camera to monitor the edges of the road and the painted side marker lines. Ifthe vehicle is about to cross the edge of the road, the function will attempt to steer the vehicle back onto the road. If this is not sufficient to keep the vehicle on the road, the brakes will also be applied. However, the function will not provide either
steering assistance or braking if the turn signal is used. The function will also not be activated if it detects that the driver is actively operating thevehicle. After the system has automatically intervened, this text message will appear in the instrumentpanel:
•
Collision avoidance assistance –Automatic intervention
WARNING
• The "Steering assistance at risk of run- off" subfunction is supplementary driversupport intended to help improve drivingsafety – it cannot handle all situations inall traffic, weather and road conditions.
• The function cannot detect barriers, railsor similar obstacles at the side of theroad.
• "Steering assistance at risk of run-off" isnot a substitute for the driver's attentionand judgment.

Park Assist*
The Park Assist function can help the driver
when maneuvering in tight spaces by indicating distances to obstacles using audible signals andgraphics in the center display.
Display view showing obstacle zones and sensor sec- tors.
The center display shows an overview of the vehi- cle in relation to objects that have been detected. The marked sector indicates where the obstacle is located. The closer the vehicle symbol is to amarked sector, the closer the detected obstacleis to your vehicle. The audible signals will also speed up the closer the obstacle is to the vehicle. The volume of theaudio system will be automatically lowered. Audible signals for obstacles in front and to the sides of the vehicle are active when the vehicle is moving but will cease after the vehicle has beenstationary for approx. 2 seconds. Audible signalsfor obstacles behind the vehicle will remain activeeven when the vehicle is stationary. If a detected obstacle is within 30 cm (1 ft) from the front or rear of the vehicle, the tone willbecome constant and the active sensor's fieldclosest to the vehicle symbol will be filled in. The volume of the Park Assist audible signals can be adjusted while the signal is being given using the
>II knob or in the center display's Top
view under
Settings.
NOTE
• Acoustic warnings are only given for objects directly in front of the vehicle'spath.
WARNING
•The Parking Assist function is supple- mentary driver support intended to facili-tate driving and help make it safer – itcannot handle all situations in all traffic,weather and road conditions.
• The parking sensors have dead/blindspots where objects cannot be detected.
