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
Warning display :
Warnin gdisplay
Active Blind Spot Assist is not active at
speeds below approximately 30 km/h. Vehi-
cles in the monitoring range are then not indi-
cated. If Active Blind Spot Assist is activated, indi-
cator lamp
:in the exterior mirror slights up
yellow up to aspeed of 30 km/h. At speeds
above 30 km/h, the indicator lamp goes out
and Active Blind Spot Assist is operational.
If av ehicle is detected within the monitoring
range of Blind Spot Assist at speeds above
30 km/h, warning lamp :on the corre-
spondin gside lights up red. Awarning is
alway sissued when avehicle enters the mon-
itorin grange of Blind Spot Assist from behind
or from the side. When you overtake avehicle,
the warning only occur sifthe difference in
speed is less than 12 km/h.
The yellow indicator lamp goes out if reverse gear is engaged. Active Blind Spot Assist is
not operational.
The brightness of the warning lamps is auto-
matically adapted to the brightness of the
surroundings.
Visua land acoustic collision warning
If you switch on the turn signals to change
lanes and avehicle is detected in the side
monitoring range, you receive avisual and
acoustic collision warning. You then hear a
double warning tonea nd red warning lamp:
flashes. If the turn signal remains on, detec-
ted vehicles are indicated by the flashing of
red warning lamp :.There are no further
warning tones.
Course-correcting brak eapplication
If Active Blind Spot Assist detects arisk of a
side impact in the monitoring range, acourse-
correcting brake application is carried out.
This is designed to help you avoid acollision. G
WARNING
Ac ourse-correcting brake application cannot
alway spreven tacollision. There is arisk of an
accident.
Always steer ,brake or accelerat eyourself,
especially if Active Blind Spot Assist warns
you or makes acourse-correcting brake appli-
cation .Always maintain asafe distanc eatthe

tored with the aid of the rada rsensor system.
Active Lane Keeping Assist detects lane
markings on the road and can warn you
before you leave yourl ane unintentionally.If
you do not react to the warning, alane-cor-
recting application of the brakes can bring the
vehicl eback into the original lane.
This function is available withi naspeedrange
between 60 km/h and 200 km/h.
For Active Lane Keeping Assist to assist you
when driving, the rada rsensor system must
be operational.
Important safety notes
If you fail to adapt yourd riving style,Active
Lane Keeping Assist can neither reduce the
risk of an accident nor overrid ethe lawsof
physics. Active Lane Keeping Assist cannot
take account of road and weather conditions.
It may not detect traffic situations. Active
Lane Keeping Assist is only an aid.Y ou are
responsible for the distance to the vehicl ein
front, for vehicl espeed, for braking in good
time, and for staying in lane.
Active Lane Keeping Assist cannot continu-
ousl ykeep yourv ehicleini ts lane. G
WARNING
Active Lane Keeping Assist cannot always
clearly detect lane markings.
In such cases, Active Lane Keeping Assist
can:
R give an unnecessary warning and then
make acourse-correcting brake application
to the vehicle
R neither give awarning nor intervene
There is arisk of an accident.
Always pay particular attention to the traffic
situation and keep withi nthe lane, especially
if Active Lane Keeping Assist alerts you.T er-
minate the intervention in anon-critical driv-
ing situation. The system may be impaired or may not func-
tion if:
R there is poor visibility, e.g. due to insuffi-
cient illumination of the road ,ordue to
snow, rain, fog or spray
R there is glare, e.g. from oncoming traffic,
the sun or reflectio nfrom other vehicles
(e.g. if the road surface is wet)
R the windscreen is dirty ,misted up, dam-
agedorc overed, for instance by asticker,
in the vicinity of the camera
R the rada rsensors in the front or rear bump-
ers or the radiator trim are dirty ,e.g.
obscured by snow
R no or several, unclea rlane markings are
present for one lane, e.g. in aconstruction
area
R the lane markings are worn away,d ark or
covered up, e.g. by dirt or snow
R the distance to the vehicl einfront is too
smal land the lane markings thus cannot be
detected
R the lane markings change quickly, e.g.
lanes branch off, cross one another or
merge
R the road is narrow and winding
R there are highly variable shad econditions
on the road
If no vehicl eisdetected in the adjacent lane
and broken lane markings are detected, no
lane-correcting brake application is made.
Warning vibratio nthrough the steering
wheel
Aw arning may be given if afront wheel
passes over alane marking. It willw arny ou by
means of intermittent vibration in the steer-
ing whee lfor up to 1.5 seconds.
