When ATTENTION ASSIST is deactivated, the
ésymbol appears in the multifunction
display in the assistance graphic display.
When ATTENTION ASSIST has been deactiva-
ted, 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 concentra-
tion are detected, a warning appears in the
multifunction display: Attention Assist:
Take a Break!
In addition to the message shown in the mul-
tifunction display, you will then hear a warn-
ing tone.
XIf necessary, take a break.
XConfirm 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
continues to detect increasing lapses in con-
centration, you will be warned again after
15 minutes at the earliest. This will only hap-
pen if ATTENTION ASSIST still detects typical
indicators of fatigue or increasing lapses in
concentration.
If a warning is output in the multifunction dis-
play, COMAND performs a service station
search. You can select a service station and
navigation to this service station will then
begin. This function can be activated and
deactivated in COMAND.
Traffic Sign Assist
General notes
Traffic Sign Assist displays the maximum
speed permitted to the driver in the instru-
ment cluster. The data and general traffic reg-
ulations stored in the navigation system are
used to determine the current speed limit. As Traffic Sign Assist is a map-based system,
traffic signs put up temporarily (e.g. near
roadworks) are not detected.
If a traffic sign that is relevant to your vehicle
is passed, the display of the speed limits is
updated.
Traffic signs with a restriction indicated by an
additional sign (e.g. in wet conditions) are
also shown.
The traffic signs are only displayed with the
restrictions if:
Rthe regulation must be observed with the
restriction, or
RTraffic Sign Assist is unable to determine
whether the restriction applies
If Traffic Sign Assist is unable to determine a maximum permitted speed from any of the
available sources, no speed limit is displayed
in the instrument cluster either.
Traffic Sign Assist is not available in all coun-
tries. In this case, symbol :is shown in the
assistance graphic display (
Ypage 243).
Important safety notes
Traffic Sign Assist is only an aid and is not
always able to correctly display speed limits.
Traffic signs always have priority over the
Traffic Sign Assist display.
The system may be either functionally
impaired or temporarily unavailable if the
information in the digital street map of the
navigation system is incorrect or out of date.

In such cases, Active Lane Keeping Assist
can:
Rgive an unnecessary warning and then
make a course-correcting brake application
to the vehicle
Rnot give a warning or 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:
Rthere is poor visibility, e.g. due to insuffi-
cient illumination of the road, or due to
snow, rain, fog or spray
Rthere is glare, e.g. from oncoming traffic,
the sun or reflections (e.g. when the road
surface is wet)
Rthe windshield is dirty, fogged up, damaged or covered, for instance by a sticker, in the
vicinity of the camera
Rthe radar sensors in the front or rear bump-
ers or the radiator trim are dirty, e.g.
obscured by snow
Rthere are no, several or unclear lane mark- ings for a lane, e.g. in areas with road con-
struction work
Rthe lane markings are worn away, dark or
covered up, e.g. by dirt or snow
Rthe distance to the vehicle in front is too
small and the lane markings thus cannot be
detected
Rthe lane markings change quickly, e.g.
lanes branch off, cross one another or
merge
Rthe road is narrow and winding
Rthere are strong shadows cast 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 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 steer-
ing wheel for up to 1.5 seconds.
In order that you are warned only when nec-
essary and in good time if you cross the lane
marking, the system recognizes certain con-
ditions and warns you accordingly.
The warning vibration occurs earlier if:
Ryou approach the outer lane marking on a
bend.
Rthe road has very wide lanes, e.g. a high-
way.
Rthe system recognizes solid lane markings.
The warning vibration occurs later if:
Rthe road has narrow lanes.
Ryou cut the corner on a bend.
Lane-correcting brake application
If you leave your lane, under certain circum-
stances the vehicle will brake briefly on one
side. This is meant to assist you in bringing
the vehicle back to the original lane.
GWARNING
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.
GWARNING
Active Lane Keeping Assist does not detect
traffic conditions or road users. In very rare
cases, the system may make an inappropriate brake application, e.g. after intentionally driv-
ing 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
226Driving systems
Driving and parking
there is sufficient distance on the side for
other traffic or obstacles.
If a lane-correcting brake application occurs,
display:appears in the multifunction dis-
play. The brake application also slightly
reduces vehicle speed.
A lane-correcting brake application can be
made after driving over a lane marking rec-
ognized as being solid or broken. Before this,
a warning must be given by means of inter-
mittent 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 detec-
ted in the adjacent lane. The following vehi-
cles can have an influence on brake applica-
tion: oncoming traffic, vehicles that are over-
taking and vehicles that are driving parallel to
your vehicle.
iA 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:
Ryou clearly and actively steer, brake or
accelerate.
Ryou cut the corner on a sharp bend.
Ryou have switched on the turn signal.
Ra driving safety system intervenes, e.g.
ESP®, PRE-SAFE®Brake or Active Blind
Spot Assist.
Ryou have adopted a sporty driving style with
high cornering speeds or high rates of
acceleration.
RESP®is switched off.
Rthe transmission is not in position D.
Ra loss of tire pressure or a defective tire has
been detected and displayed.
Ran 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 you:
Rsteer slightly in the opposite direction
Rswitch on the turn signal
Rclearly brake or accelerate
A lane-correcting brake application is inter-
rupted automatically if:
Ra driving safety system intervenes, e.g.
ESP®, PRE-SAFE®Brake or Active Blind
Spot Assist.
Rlane markings can no longer be recognized.
