General notes ATTENTION ASSIST helps you during long,
monotonous journeys such as on motorways
and trunk roads. It is active in the 60 km/h to
200 km/h range. If ATTENTION ASSIST
detects typical indicators of fatigue or
increasing lapses in concentration on the part
of the driver, it suggests taking a break. Driving systems

Warning display
:
Warning display
Active Blind Spot Assist is not operational at
speeds below approximately 30 km/h. Vehi-
cles in the monitoring range are then not indi-
cated.
If a vehicle is detected within the monitoring
range of Blind Spot Assist at speeds above
30 km/h, warning lamp :on the corre-
sponding side lights up red. This warning
always lights up when a vehicle enters the
blind spot monitoring range from behind or
from the side. When you overtake a vehicle,
the warning only occurs if the difference in
speed is less than 12 km/h.
If you select the reverse gear, Active Blind
Spot Assist is not operational.
The brightness of the warning lamps is auto-
matically adapted to the brightness of the
surroundings. When Active Blind Spot Assist is activated,
grey radar waves propagating backwards
appear next to the vehicle in the assistance
display in the multifunction display. Above a
speed of 30 km/h, the colour of the radar
waves in the assistance display changes to
green ;. Active Blind Spot Assist is then
ready for use. Visual and acoustic collision warning
If you switch on the turn signals to change
lanes and a vehicle is detected in the side
monitoring range, you receive a visual and
acoustic collision warning. You will then hear
a double warning tone and red warning
lamp :flashes. If the turn signal remains on,
detected vehicles are indicated by the flash-
ing of red warning lamp :. There are no fur-
ther warning tones.
Course-correcting brake application
If Active Blind Spot Assist detects a risk of a
side impact in the monitoring range, a course- correcting brake application is carried out.
This is designed to help you avoid a collision. G
WARNING
A course-correcting brake application cannot 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 appli-
cation. Always maintain a safe distance at the sides. If a course-correcting brake application
occurs, red warning lamp
:flashes in the
exterior mirror and a dual warning tone
sounds. In addition, display ;underlining
the danger of a side collision appears in the
multifunction display.
In very rare cases, the system may make an
inappropriate brake application. A course-
correcting brake application may be interrup- Driving systems
235Driving and parking Z

ted at any time if you steer slightly in the
opposite direction or accelerate.
The course-correcting brake application is
available in the speed range between
30 km/h and 200 km/h.
Either a course-correcting brake application
appropriate to the driving situation, or none at all, may occur if:
R there are vehicles or obstacles, e.g. crash
barriers, on both sides of your vehicle
R a vehicle approaches too closely on the
side
R you have adopted a sporty driving style with
high cornering speeds
R you clearly brake or accelerate
R a driving safety system intervenes, such as
ESP ®
or PRE-SAFE ®
Brake
R ESP ®
is deactivated
R a loss of tyre pressure or a defective tyre is
detected
Activating Active Blind Spot Assist
X Make sure that Active Blind Spot Assist is
activated in the on-board computer
(Y page 259).
X Turn the key to position 2in the ignition
lock.
Warning lamps :in the exterior mirrors
light up red for approximately 1.5 second s.
Grey radar waves propagating backwards
appear next to the vehicle in the assistance
display in the multifunction display. Active Lane Keeping Assist General notes
Active Lane Keeping Assist monitors the area
in front of your vehicle by means of camera
system :at the top of the windscreen. Var-
ious different areas to the front, rear and side
of your vehicle are also monitored with the aid
of the radar sensor system. Active Lane Keep-
ing Assist detects lane markings on the road
and can warn you before you leave your lane
unintentionally. If you do not react to the
warning, a lane-correcting application of the
brakes can bring the vehicle back into the
original lane.
If you select km kmin the Display unit
Display unit
Speed-/odometer
Speed-/odometer function on the on-board
computer (Y page 261), Active Lane Keeping
Assist is activated starting at a speed of
60 km/h. If the miles milesdisplay unit is selected,
the assistance range begins at 40 mph.
Important safety notes
If you fail to adapt your driving style, Active
Lane Keeping Assist can neither reduce the
risk of an accident nor override the laws of
physics. Active Lane Keeping Assist cannot
take account of road and weather conditions. It may not recognise traffic situations. Active Lane Keeping Assist is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time, and for staying in lane.
Active Lane Keeping Assist cannot continu-
ously keep your vehicle in its lane. 236

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 a course-correcting brake application
to the vehicle
R neither 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 func-
tion if:
R there is poor visibility, e.g. due to insuffi-
cient illumination of the road, or due to
snow, rain, fog or spray
R there is glare, e.g. from oncoming traffic,
the sun or reflection from other vehicles
(e.g. if the road surface is wet)
R the windscreen is dirty, misted up, dam-
aged or covered, for instance by a sticker,
in the vicinity of the camera
R the radar sensors in the front or rear bump-
ers or the radiator trim are dirty, e.g.
obscured by snow
R no, or several, unclear lane markings are
present for one lane, e.g. in a construction
area
R the lane markings are worn away, dark or
covered up, e.g. by dirt or snow
R the distance to the vehicle in front is too
small and 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 shade conditions
on the road If no vehicle is detected in the adjacent lane
and broken lane markings are detected, no
lane-correcting brake application is made.
Warning vibration through the steering
wheel
A warning may be given if a front wheel
passes over a lane marking. It will warn you by means of intermittent vibration in the steer-
ing wheel for up to 1.5 seconds.
Lane-correcting brake application
If you leave your lane under certain circum-
stances, the vehicle will brake briefly on one
side. This is intended to help you return the
vehicle to the original lane. G
WARNING
A lane-correcting brake application cannot
always bring the vehicle back into the original 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 appli-
cation. If a lane-correcting brake application occurs,
display :appears in the multifunction dis-
play. The brake application also slightly
reduces driving speed.
This function is available in the range between
60 km/h and 200 km/h.
A lane-correcting brake application can be
made after driving over a lane marking rec-
ognised as being solid or broken. Before this,
a warning must have been issued by means of
intermittent vibration through the steering Driving systems
237Driving and parking Z

wheel. In addition, a lane with lane markings
on both sides must be recognised.
In the case of a broken lane marking being
detected, a lane-correcting brake application can only be made if a vehicle has been detec-
ted in the adjacent lane. Oncoming vehicles,
overtaking vehicles and vehicles in adjacent
lanes can be detected.
i A further lane-correcting brake applica-
tion can only occur after your vehicle has
returned to the original lane.
No lane-correcting brake application occurs
if:
R you clearly and actively steer, brake or
accelerate
R you cut the corner on a sharp bend
R you have switched on the turn signal
R a driving safety system intervenes, such as
ESP ®
, PRE-SAFE ®
Brake or Active Blind
Spot Assist
R you have adopted a sporty driving style with
high cornering speeds or high rates of
acceleration
R ESP ®
is deactivated
R the transmission is not in position D
R a loss of tyre pressure or a defective tyre
has been detected and displayed
R an obstacle in the lane in which you are
driving has been detected
Active Lane Keeping Assist may not detect
other road users or traffic situations. An inap- propriate brake application may be interrup-
ted at any time if:
R you steer slightly in the opposite direction
R you switch on the turn signal
R you clearly brake or accelerate
A lane-correcting brake application is inter-
rupted automatically if:
