GWarning!
The ATTENTION ASSIST is only an aid to the
driver. It might not recognize fatigue or
increasing inattentiveness in time or fail to
recognize them at all. The system cannot
substitute a rested and attentive driver.
Fatigue can cause you to recognize dangers
too late, to misjudge potential dangers, or to
react slower. Therefore, make sure to be
rested before and during your trip. Take rests
early enough and regularly, especially during
long trips. Failure to do so could cause you to
recognize dangers too late which could result
in an accident and serious injury to you and/
or others.
The ATTENTION ASSIST interprets your
fatigue or increasing inattentiveness
considering the following criteria:
Rthe individual driving style, for example the
way you steer
Rthe driving conditions such as time of day
and duration of the ride
The ATTENTION ASSIST function is restricted
and warnings will be delayed or not issued at
all when
Rroad conditions are bad, e.g. heavy bumps
or potholes
Rcrosswinds are strong
Rdriving in a sporty manner with high speed
in curves or rapid acceleration
Rdriving slower than 50 mph (80 km/h) or
faster than 112 mph (180 km/h) most of
the time
Roperating the COMAND or making phone
calls via COMAND
Rchanging lanes or varying the vehicle
speed, i.e. you intervene actively
Warnings and displays in the
multifunction display

control system (Y page 232).
ATTENTION ASSIST indicator \000F appears in
the multifunction display.
When the ATTENTION ASSIST is active, it will
warn you after 20 minutes of driving at the
earliest. An intermittent warning will then
sound twice and the message Attention
Assist: Time for a rest? appears in the
multifunction display.
XIf possible park your vehicle in a safe
location and take a rest.
XConfirm the message by pressing button
\000d on the multifunction steering wheel.
If you do not take a rest and the
ATTENTION ASSIST continues to recognize
fatigue or increasing inattentiveness, you will
be warned once more after 15 minutes at the
earliest.
During long trips, take regular and duly rests
that allow you to recover sufficiently.
The ATTENTION ASSIST will be reset and
restarts evaluating the degree of your fatigue
when
Ryou turn off the engine
Ryou release the seat belt and open the
driver’s door, e.g. during a rest or for a

Lane Keeping Assist
The Lane Keeping Assist supports you at a
vehicle speed of above 40 mph when you
have set the display unit to miles in the
Display Unit Speed-/Odometer: menu in
the control system (Y page 235). When you
have set the display unit to km, the system
supports you at a vehicle speed of above
60 km/h. When the Lane Keeping Assist
detects lane markings, the system is
designed to alert you in case you leave your
lane unintentionally. A warning is usually
issued when a front wheel is on the lane
marking. An interval vibration in the steering
wheel that lasts for up to 1.5 seconds will
then alert you.
The Lane Keeping Assist monitors the area in
front of your vehicle via camera \000F.
The system can distinguish various
conditions in order to alert you early enough
and to avoid unnecessary warnings when
crossing lane markings.
The warning is issued sooner when
Rcutting a curve on the outside of the turn
Rdriving on very wide lanes such as highway
lanes
Rthe system recognizes dividing lines
because crossing them is often crucial due
to soft shoulders or guardrails behind for
example
The warning is issued later however when
Rdriving on narrow lanes
Rcutting a curve on the inside of the turn
The system does not issue a warning when
Rsteering, braking, or accelerating in a
clearly active manner, e.g. when changing
lanes, passing, exiting a highway
Rcutting a narrow curve
Rmaking a very sharp turn
Ra driving safety system such as the ABS,
the BAS, or the ESC has been activated
When setting the turn signal in either
direction, the warning will be suppressed. The
system will issue a warning if a turn signal has
been on for an extended period of time.
GWarning!
The Lane Keeping Assist does not keep the
vehicle in the lane. The Lane Keeping Assist
is only an aid to the driver and may not always
recognize lane markings properly or fail to
recognize them at all.
The system may be impaired or unavailable
when
Rvisibility is poor, e.g. due to snow, rain, fog,
or heavy spray
Roncoming traffic, sun glare or reflection
from other vehicles
Rthe camera area of the windshield is dirty,
foggy, or otherwise obstructed
Rlane markings are not present
Rlane markings are worn, dark, or covered
e.g. by snow or dirt
Rthe distance to the preceding vehicle is too
short
Rwhen lane markings are ambiguous, for
example in road work sections
Rlane markings change rapidly, e.g. on
highway exits or turn-off lanes
Rlanes are narrow and winding
The Lane Keeping Assist cannot take road and
traffic conditions into account. It is the
driver’s responsibility at all times to be
attentive to road, weather and traffic
