Monitoring area
GWARNING
Active Blind Spot Assist does not detect all
traffic situations and road users. There is a
risk of an accident.
Always make sure that there is sufficient
distance on the side for other traffic or
obstacles.
Active Blind Spot Assist monitors the area upto 10 ft (3.0 m) behind your vehicle anddirectly next to your vehicle, as shown in thediagram.
The detection of obstacles can be impaired inthe case of:
Rthere is dirt on the sensors or anything elsecovering the sensors
Rpoor visibility, e.g. due to rain, snow orspray
Vehicles in the monitoring range are then notindicated.
Active Blind Spot Assist may not detect narrowvehicles, such as motorcycles or bicycles, ormay only detect them too late.
If the lanes are narrow, vehicles driving in thelane beyond the lane next to your vehicle maybe indicated, especially if the vehicles are notdriving in the middle of their lane. This may bethe case if there are vehicles driving at theinner edge of their lanes.

Due to the nature of the system:
Rwarnings may be issued in error when driv-ing close to crash barriers or similar solidlane borders.
Rwarnings may be interrupted when drivingalongside particularly long vehicles, e.g.trucks, for a prolonged time.
Indicator and warning display
CYellow indicator lamp/red warning lamp
Active Blind Spot Assist is not active at speedsbelow approximately 20 mph (30 km/h). Vehi-cles in the monitoring range are then not indi-cated.
When Active Blind Spot Assist is activated,indicator lampCin the exterior mirrors lightsup yellow at speeds of up to 20 mph(30 km/h). At speeds above 20 mph(30 km/h), the indicator lamp goes out andActive Blind Spot Assist is operational.
If a vehicle is detected within the monitoringrange at speeds above approximately 20 mph(30 km/h), warning lampCon the corre-sponding side lights up red. This warningalways occurs when a vehicle enters the moni-toring range from behind or from the side.When you overtake a vehicle, the warning onlyoccurs if the difference in speed is less than7 mph (12 km/h).
The yellow indicator lamp goes out if reversegear is engaged. In this event, Active BlindSpot Assist is no longer active.
The brightness of the indicator/warning lampsis adjusted automatically according to theambient light.
Visual and acoustic collision warning
If you switch on the turn signals to changelanes and a vehicle is detected in the sidemonitoring range, you receive a visual andacoustic collision warning. You will then hear a
double warning tone and red warning lampCflashes. If the turn signal remains on, detectedvehicles are indicated by the flashing of redwarning lampC. There are no further warningtones.
Course-correcting brake application
If Active Blind Spot Assist detects a risk of alateral collision in the monitoring range, acourse-correcting brake application is carriedout. This is meant to assist you in avoiding acollision.
GWARNING
A course-correcting brake application can-
not always prevent a collision. There is a risk
of an accident.
Always steer, brake or accelerate yourself,
especially if Active Blind Spot Assist warns
you or makes a course-correcting brake
application. Always maintain a safe distance
at the sides.
If a course-correcting brake applicationoccurs, red warning lampCflashes in theexterior mirror and a dual warning tonesounds. In addition, displayDunderlining thedanger of a side collision appears in the multi-function display.
In very rare cases, the system may make aninappropriate brake application. A course-cor-recting brake application may be interruptedat any time, e.g. if you steer slightly in theopposite direction or depress the acceleratorpedal more firmly.
The course-correcting brake application isavailable in the speed range between 20 mph(30 km/h) and 120 mph (200 km/h).

Active Lane Keeping Assist
General notes
Active Lane Keeping Assist monitors the areain front of your vehicle by means of multifunc-tion cameraCat the top of the windshield.Various areas to the front, rear and side ofyour vehicle are also monitored with the aid ofthe radar sensor system. Active Lane KeepingAssist detects lane markings on the road andcan warn you before you leave your lane unin-tentionally. If you do not react to the warning,a lane-correcting application of the brakes canbring the vehicle back into the original lane.
This function is available in a speed rangebetween 40 mph and 120 mph (60 km/h and200 km/h).
For Active Lane Keeping Assist to assist youwhen driving, the radar sensor system must beoperational.
Important safety notes
If you fail to adapt your driving style, ActiveLane Keeping Assist can neither reduce therisk of accident nor override the laws of phys-ics. Active Lane Keeping Assist cannot takeinto account road, weather or traffic condi-tions. Active Lane Keeping Assist is only anaid. You are responsible for the distance to thevehicle in front, for vehicle speed, for brakingin good time and for staying in your lane.
Active Lane Keeping Assist cannot continu-ously keep your vehicle in its lane.
GWARNING
Active Lane Keeping Assist cannot always
clearly detect lane markings.

In such cases, Active Lane Keeping Assist
can:
Rgive an unnecessary warning and then
make a course-correcting brake applica-
tion
Rneither give a warning nor intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, espe-
cially if Active Lane Keeping Assist alerts
you. Terminate the intervention in a non-crit-
ical driving situation.
The system may be impaired or may not func-tion if:
Rthere is poor visibility, e.g. due to insuffi-cient illumination of the road, or due tosnow, rain, fog or heavy spray
Rthere is glare, e.g. from oncoming traffic,the sun or reflection from other vehicles(e.g. if the road surface is wet)
Rthe windshield is dirty, fogged up, damagedor covered, for instance by a sticker, in thevicinity of the camera
Rthere are no lane markings, or severalunclear lane markings are present, e.g.around construction sites
Rthe lane markings are worn away, dark orcovered up, e.g. by dirt or snow
Rthe distance to the vehicle in front is tooshort and thus the lane markings cannot bedetected
Rthe lane markings change quickly, e.g. lanesbranch off, cross one another or merge
Rthe road is narrow and winding
Rthere are highly variable shade conditionson the roadway
Rno vehicle is detected in the adjacent laneand there are broken lane markings
Warning vibration in the steering wheel
A warning may be given if a front wheel passesover a lane marking. You will then be warnedby means of a vibration through the steeringwheel lasting for up to 1.5 seconds.
In order that you are warned only when neces-sary and in good time if you cross the lanemarking, the system detects certain condi-tions and warns you accordingly.
The warning vibration occurs earlier if:
Ryou approach the outer lane marking on abend
Rthe road has very wide lanes, e.g. a freeway
Rthe system detects solid lane markings
The warning vibration occurs later if:
Rthe road has narrow lanes
Ryou cut the corner on a bend
Lane-correcting brake application
GWARNING
A lane-correcting brake application cannot
always bring the vehicle back into the origi-
nal lane. There is a risk of an accident.
Always steer, brake or accelerate yourself,
especially if Active Lane Keeping Assist
warns you or makes a lane-correcting brake
application.
GWARNING
Active Lane Keeping Assist only detects traf-
fic conditions or road users to a limited
extent. In very rare cases, the system may
make an inappropriate brake application,
e.g. after intentionally driving over a solid
lane marking. There is a risk of an accident.
An inappropriate brake application may be
interrupted at any time if you steer slightly
in the opposite direction. Always make sure
that there is sufficient distance on the side
for other traffic or obstacles.
In rare cases, Active Lane Keeping Assistcould detect broken line markings or specialstructures on the road surface as solid lanemarkings. An inappropriate brake applicationcan be interrupted at any time, for example ifyou steer slightly in the opposite direction.
