RCrossing vehicles: Active Distance AssistDISTRONIC may mistakenly detect vehiclesthat are crossing your lane. Activating ActiveDistance Assist DISTRONIC at, for example, atraffic light with crossing traffic could causeyour vehicle to pull away at the wrong time.
In such situations, brake if necessary. ActiveDistance Assist DISTRONIC will then be deacti-vated.
Active Distance Assist DISTRONIC with
Active Steering Assist
General notes
Active Distance Assist DISTRONIC with ActiveSteering Assist aids you in keeping the vehicle inthe center of the driving lane by means of mod-erate steering interventions in a speed rangefrom 0 - 125 mph (0 - 200 km/h).
It monitors the area in front of your vehicle bymeans of multifunction cameraC, which ismounted at the top of the windshield.
In a speed range from 0 - 37 mph (0 - 60 km/h),Active Steering Assist focuses on the vehicle infront, taking into account lane markings, e.g.when following vehicles in a traffic jam.
At speeds of more than 37 mph (60 km/h),Active Steering Assist focuses on clear lanemarkings (left and right), focusing on the vehiclein front only if clear lane markings are not pres-ent.
If these conditions are not present, Active Steer-ing Assist cannot provide assistance.
Active Distance Assist DISTRONIC must beactive in order for the function to be available.
Important safety notes
Active Distance Assist DISTRONIC with ActiveSteering Assist can neither reduce the risk of anaccident if you fail to adapt your driving style noroverride the laws of physics. Active DistanceAssist DISTRONIC with Active Steering Assistcannot take into account road, weather or trafficconditions. Active Distance Assist DISTRONICwith Active Steering Assist is only an aid. You areresponsible for maintaining a safe distance tothe vehicle in front, for vehicle speed, for brak-ing in good time and for staying in lane.
Active Distance Assist DISTRONIC with ActiveSteering Assist does not detect road and trafficconditions and does not detect all road users. Ifyou are following a vehicle which is drivingtowards the edge of the road, your vehicle couldcome into contact with the curb or other roadboundaries. Be particularly aware of other roadusers, e.g. cyclists, that are directly next to yourvehicle.
Obstacles such as traffic pylons at roadworks onthe lane or projecting out into the lane are notdetected.
An inappropriate steering intervention, e.g. afterintentionally driving over a lane marking, can becorrected at any time if you steer slightly in theopposite direction.
Active Distance Assist DISTRONIC with ActiveSteering Assist cannot continuously keep yourvehicle in lane. In some cases, steering inter-vention is not sufficient to bring the vehicle backto the lane. In such cases, you must steer thevehicle yourself to ensure that it does not leavethe lane.
The system may be impaired or may not functionif:
Rthere is poor visibility, e.g. due to insufficientillumination of the road, or due to snow, rain,fog or heavy spray
Rthere is glare, e.g. from oncoming traffic, thesun or reflection from other vehicles (e.g. ifthe road surface is wet)
Rthe windshield is dirty, fogged up, damaged orcovered, for instance by a sticker, in the vicin-ity of the camera
Rthere are no or several unclear lane markingsfor one lane, e.g. roadworks
Rthe lane markings are worn away, dark or cov-ered up, e.g. by dirt or snow

360° Camera
General notes
The 360° camera is a system consisting of fourcameras.
The system processes images from the follow-ing cameras:
RRear view camera
RFront camera
RTwo side cameras in the exterior mirrors
The cameras cover the immediate surroundingsof the vehicle. The system supports you, forexample when parking or if vision is restricted atan exit.
You can show images from the 360° camera infull-screen mode or in seven different split-screen views on the multimedia system. A split-screen view also includes a top view of the vehi-cle. This view is calculated from the data sup-plied by the installed cameras (virtual camera).
The seven split-screen views are:
RTop view and picture from the rear view cam-era (130° viewing angle)
RTop view and image from the front camera(130° viewing angle without displaying themaximum steering wheel angle)
RTop view and enlarged rear view
RTop view and enlarged front view
RTop view and trailer view (vehicles with trailertow hitch)
RTop view and images from the rear-facing sidecameras (rear wheel view)
RTop view and images from the forward-facingside cameras (front wheel view)
When the function is active and you shift thetransmission from[or^to\\, the guidelines on the multimedia system are hidden.
When you shift between transmission positions[and^, you see the previously selected frontor rear view.
Distances measured by Parking AssistPARKTRONIC will also be optically displayed:
Rin split screen view as red or yellow bracketsaround the vehicle icon in the top view, or
Rat the bottom right as red or yellow bracketsaround the vehicle symbol in full-screen mode
The line thickness and color of the bracketsshow how far the vehicle is from an object.
Ryellow brackets with thin lines: Parking AssistPARKTRONIC is active
Ryellow brackets with normal lines: an object ispresent in close range of the vehicle
Rred line: an object is present in the immediateclose range of the vehicle
Important safety notes
The 360°camera is only an aid and may show adistorted view of obstacles, show them incor-rectly or not at all. The 360°camera is not asubstitute for attentive driving.
You are always responsible for safe maneuver-ing and parking. Make sure that there are nopersons, animals or objects in the maneuveringarea while maneuvering and parking in parkingspaces.
You are always responsible for safety, and mustalways pay attention to your surroundings whenparking and maneuvering. This applies to theareas behind, in front of and beside the vehicle.You could otherwise endanger yourself and oth-ers.

sors. A warning lamp lights up in the exteriormirrors and draws your attention to vehiclesdetected in the monitored area. If you thenswitch on the corresponding turn signal tochange lanes, you will also receive a visual warn-ing and a warning tone.
Blind Spot Assist supports you from a speed ofapproximately 20 mph (30 km/h).
Important safety notes
GWARNING
Blind Spot Assist does not react to:
Rvehicles overtaken too closely on the side,
placing them in the blind spot area
Rvehicles which approach with a large speed
differential and overtake your vehicle
As a result, Blind Spot Assist may not give
warnings in such situations. There is a risk of
an accident.
Always observe the traffic conditions care-
fully, and maintain a safe lateral distance.
Blind Spot Assist is only an aid. It may fail todetect some vehicles and is no substitute forattentive driving. Always ensure that there issufficient distance to the side for other roadusers and obstacles.

Radar sensors
The radar sensors for Blind Spot Assist are inte-grated into the rear bumper. Make sure that thebumpers are free from dirt, ice or slush. Thesensors must not be covered, for example bycycle racks or overhanging loads. Following asevere impact or in the event of damage to thebumpers, have the function of the radar sensorschecked at a qualified specialist workshop.Blind Spot Assist may no longer work properly.
Monitoring area
In particular, the detection of obstacles can beimpaired if:
RThere is dirt on the sensors or anything elsecovering the sensors
Rthere is poor visibility, e.g. due to fog, heavyrain, snow or spray
Rthere are narrow vehicles, e.g. motorcycles orbicycles
Rthe road has very wide lanes
Rthe road has narrow lanes
Ryou are not driving in the middle of the lane
Rthere are barriers or other road boundaries
Vehicles in the monitoring range are then notindicated.
At a distance of around 1.6 ft (0.5 m)Dfrom thevehicle, Blind Spot Assist monitors the area upto 10 ft (3 m) next to

This function is available in the range between40 mph and 120 mph (60 km/hand 200 km/h).
A warning may be given if a front wheel passesover a lane marking. It will warn you by means ofintermittent vibration in the steering wheel forup to 1.5 seconds.
Important safety notes
GWARNING
Lane Keeping Assist cannot always clearly
detect lane markings.
In such cases, Lane Keeping Assist can:
Rgive an unnecessary warning

situation and keep within the lane, especially
if Lane Keeping Assist alerts you.
GWARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There is
a risk of an accident.
You should always steer, brake or accelerate
yourself, in particular if warned by Lane Keep-
ing Assist.
