Radar sensors
The Active Blind Spot Assist radar sensors areintegrated into the front and rear bumpers andbehind a cover in the radiator trim. Make surethat the bumpers and the cover in the radiatorgrill are free of dirt, ice or slush. The rear sensorsmust not be covered, for example by cycle racksor overhanging loads. Following a severe impactor in the event of damage to the bumpers, havethe function of the radar sensors checked at aqualified specialist workshop. Active Blind SpotAssist may otherwise no longer work properly.
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 dis-
tance on the side for other traffic or obstacles.
At a distance of approximately 1.6 ft (0.5m)Dfrom the vehicle, Active Blind Spot Assist mon-itors the area up to 10 ft (3 m) next to

Active Lane Keeping Assist
General notes
Active Lane Keeping Assist monitors the area infront of your vehicle by means of multifunctioncameraCat the top of the windshield. Variousdifferent areas to the front, rear and side of yourvehicle are also monitored with the aid of theradar 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, alane-correcting application of the brakes canbring the vehicle back into the original lane.
This function is available in the range between40 mph and 120 mph (60 km/h and 200 km/h).
Important safety notes
If you fail to adapt your driving style, Active LaneKeeping Assist can neither reduce the risk of anaccident nor override the laws of physics. ActiveLane Keeping Assist cannot take account ofroad and weather conditions. It may not recog-nize traffic situations. Active Lane KeepingAssist is only an aid. You are responsible for thedistance to the vehicle in front, for vehiclespeed, for braking in good time and for staying inyour lane.
Active Lane Keeping Assist cannot continuouslykeep 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 application
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, especially
if Active Lane Keeping Assist alerts you. Ter-
minate the intervention in a non-critical driv-
ing situation.
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
Rthe radar sensors in the front or rear bumpersor the radiator trim are dirty, e.g. obscured bysnow
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
Rthe distance to the vehicle in front is too shortand thus the lane markings cannot be detec-ted
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 conditions onthe roadway
If no vehicle is detected in the adjacent lane andbroken lane markings are detected, no lane-cor-recting brake application is made.
Warning vibration in the steering wheel
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.
