Activating ATTENTION ASSIST
X
Activate ATTENTION ASSIST using the on-
board computer (Y page 248).
The system determines the attention level
of the driver depending on the setting
selected:
Standard selected: the sensitivity with
which the system determines the attention
level is set to normal.
Sensitive selected: the sensitivity is set
higher. The attention level detected by
Attention Assist is adapted accordingly and
the driver is warned earlier.
When ATTENTION ASSIST is deactivated, the
À symbol and OFF appear in the
multifunction display in the assistance
display when the engine is running.
When ATTENTION ASSIST has been
deactivated, it is automatically reactivated
after the engine has been stopped. The
sensitivity selected corresponds to the last
selection activated (standard/sensitive).
Warning in the multifunction display If fatigue or increasing lapses in
concentration are detected, a warning
appears in the multifunction display:
Attention Assist: Take a Break!
Attention Assist: Take a Break!
In addition to the message shown in the
multifunction display, you will then hear a
warning tone.
X If necessary, take a break.
X Confirm the message by pressing the
a button on the steering wheel.
On long journeys, take regular breaks in good
time to allow yourself to rest properly. If you
do not take a break and ATTENTION ASSIST
still detects increasing lapses in
concentration, you will be warned again after
15 minutes at the earliest. This will only
happen if ATTENTION ASSIST still detects
typical indicators of fatigue or increasing
lapses in concentration. Lane Tracking package
General notes The Lane Tracking package consists of Blind
Spot Assist (Y page 226) and Lane Keeping
Assist (Y page 228).
Blind Spot Assist General notes
Blind Spot Assist uses a radar sensor system
to monitor the areas on both sides of your
vehicle. It supports you from a speed of
approximately 20 mph (30 km/h). A warning
display in the exterior 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 a visual and audible
collision warning. Blind Spot Assist uses
sensors in the rear bumper for monitoring
purposes.
Important safety notes G
WARNING
Blind Spot Assist does not react to:
R vehicles overtaken too closely on the side,
placing them in the blind spot area
R vehicles which approach with a large speed
differential and overtake your vehicle
As a result, Blind Spot Assist may not give
warnings in such situations. There is a risk of
an accident.
Always observe the traffic conditions
carefully, and maintain a safe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving. Always ensure that there is
sufficient distance to the side for other road
users and obstacles.
i USA only:
This device has been approved by the FCC
as a "Vehicular Radar System". The radar
sensor is intended for use in an automotive
radar system only. Removing, tampering 226
Driving systemsDriving and parking
ProCarManuals.com
If a vehicle is detected within the blind spot
monitoring range at speeds above 20 mph
(30 km/h), warning lamp :on the
corresponding side lights up red. This warning
is always emitted 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 7 mph (12 km/h).
The yellow indicator lamp goes out if reverse
gear is engaged. In this event, Blind Spot
Assist is no longer active.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light.
Collision warning
If a vehicle is detected in the monitoring range
of Blind Spot Assist and you switch on the
corresponding turn signal, a double warning
tone sounds. Red warning lamp :flashes. If
the turn signal remains on, vehicles detected
are indicated by the flashing of red warning
lamp :. There are no further warning tones.
Switching on Blind Spot Assist
X Make sure that Blind Spot Assist
(Y page 248) is activated in the on-board
computer.
X Turn the SmartKey to position 2in the
ignition lock.
Warning lamps :in the exterior mirrors
light up red for approximately
1.5 seconds and then turn yellow. Lane Keeping Assist General notes
Lane Keeping Assist monitors the area in
front of your vehicle with camera
:, which is
mounted at the top of the windshield. Active
Lane Keeping Assist detects lane markings on
the road and can warn you before you leave
your lane unintentionally.
This function is available in the range between
40 mph and 120 mph (60 km/h and
200 km/h).
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
steering wheel for up to 1.5 seconds.
Important safety notes G
WARNING
Lane Keeping Assist may not always clearly
recognize lane markings.
In this case, Lane Keeping Assist may:
R give an unnecessary warning
R not give a warning
There is a risk of an accident.
Always pay particular attention to the traffic
situation and stay in lane, in particular if
warned by Lane Keeping Assist. G
WARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There
is a risk of an accident. 228
Driving systemsDriving and parking
ProCarManuals.com
If no vehicle is detected in the adjacent lane
and there are broken lane markings detected,
no lane-correcting brake application is made.
Warning vibration in 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
steering wheel for up to 1.5 seconds.
Lane-correcting brake application 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
application. G
WARNING
Active Lane Keeping Assist only detects
traffic 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. If you leave your lane, under certain
circumstances the vehicle will brake briefly on one side. This is meant to assist you in
bringing the vehicle back to the original lane.
If a lane-correcting brake application occurs,
display
:appears in the multifunction
display.
A lane-correcting brake application can be
made after driving over a lane marking
recognize as being solid or broken. Before
this, a warning must be given by means of
intermittent vibration in the steering wheel.
In addition, a lane with lane markings on both
sides must be recognized.
In the case of a broken lane marking being
detected, a lane-correcting brake application
can only be made if a vehicle has been
detected in the adjacent lane. The following
vehicles can have an influence on brake
application: oncoming traffic, vehicles that
are overtaking and vehicles that are driving
parallel to your vehicle.
i A further lane-correcting brake
application 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 adopted a sporty driving style with
high cornering speeds or high rates of
acceleration.
R you have switched on the turn signals.
R a driving safety system intervenes, e.g.
ESP ®
, PRE-SAFE ®
Brake or Active Blind
Spot Assist.
R ESP ®
is switched off.
R the transmission is not in position D.
R an obstacle has been detected in the lane
in which you are driving.
R a loss of tire pressure or a defective tire has
been detected and displayed.
There is a possibility that the Active Lane
Assistant could misjudge the given traffic 234
