Lane Keeping Assist General notes
Lane Keeping Assist monitors the area in
front of your vehicle by means of camera
:
at the top of the windscreen. Lane Keeping
Assist detects lane markings on the road and
can warn you before you leave your lane unin-
tentionally.
This function is available within aspeed range
between 60 km/h and 200 km/h.
Aw arning may be given if afront wheel
passes over alane marking. It will warn you by
means of intermittent vibration through the
steering wheel for up to 1.5 seconds.
Important safety notes G
WARNING
Lane Keeping Assist cannot always clearly
identify lane markings.
In these cases, Lane Keeping Assist may:
R give an unnecessary warning
R not give awarning
There is arisk of an accident.
Always pay particular attention to the traffic
situation and keep in lane, especiallyifL ane
Keeping Assist alerts you. Driving systems
259Driving and parking Z

Lane Keeping Assist (Y page 263).
Active Blind Spot Assist General notes
Active Blind Spot Assist monitors the areas
on either side of the vehicle that are not visi-
ble to the driver with two lateral, rear-facing
radar sensors. Awarning display in the exte-
rior mirrors draws your attention to vehicles
detected in the monitored area. If you then
switch on the corresponding turn signal to
change lanes, you will also receive avisual
and audibl ecollision warning. If arisk of side
impact is detected, corrective braking may
help you avoid acollision. Active Blind Spot
Assist evaluates the free space in the direc-
tion of travel and to the side before making a course-correcting brake application. For this,Active Blind Spot Assist uses the forward-
facing radar sensors.
Active Blind Spot Assist supports you from a
speed of approximately 30 km/h.
Important safety notes
Active Blind Spot Assist is only an aid and is
not asubstitute for attentive driving. G
WARNING
Active Blind Spot Assist does not react to
vehicles:
R overtaking too closely on the side, placing
them in the blind spot area
R if the differenc einthe speed of approach
and overtaking is too great As
aresult, Active Blind Spot Assist may nei-
ther give warnings nor intervene in such sit-
uations. There is arisk of an accident.
Always pay careful attention to the traffic sit- uation and maintain asafe distanc eatthe side
of the vehicle.
Radar sensors
The Active Blind Spot Assist radar sensors are integrated into the fronta nd rear bumpers
and behind acover in the radiator trim. Make
sure that the bumpers and the cover in the
radiator trim are free of dirt, ice or slush. The
rear sensors must not be covered, e.g. by
bicycle racks or overhangin gloads. Following
as evere impact or in the event of damage to
the bumpers, have the function of the radar
sensors checked at aqualified specialist
workshop. Active Blind Spot Assist may oth-
erwise no longer function properly.
Monitoring range G
WARNING
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-
tancetot he side for other traffic or obstacles. Example: Saloon Driving systems
261Driving and parking Z

Activ
eBlind Spo tAssist monitors the area up
to 3.0 mbehind your vehicle and directly next
to your vehicle, as shown in the diagram.
The detection of vehicles may be impaired in the case of:
R dirt on the sensor sorobscured sensors
R poor visibility, e.g. due to rain, snow or
spray
Vehicles in the monitoring range will then be
indicated late or not at all.
Active Blind Spot Assist may not detec tnar-
row vehicles, such as motorcycles or bicy-
cles, or may only detec tthem too late.
If the lanes are narrow, vehicles driving in the
lane beyond the lane nexttoy our vehicle may
be indicated, especially if the vehicles are not
driving in the middle of their lane. This may be the case if ther eare vehicles at the edge of
their lane.
Due to the nature of the system:
R warnings may be issued in error when driv-
ing close to crash barriers or similar solid
lane borders
R warnings may be interrupted when driving
alongside long vehicles, for example lor-
ries, for aprolonged time
