TTENTION ASSIST
AT TENTION ASSIST assists you on long, mono to-
nous journe ys, e.g. on mo torw ays and trunk
ro ads. If ATTENTION ASSIST de tects indicators of
fa tigue or increasing lapses in concentration on
th e part of the driver, it suggests taking a break.
AT TENTION ASSIST is only an aid. It cannot
alw ays de tect fatigue or lapses in concentration in
time. The system is not a substitute for a well-res-
te d and attentive driver. On long journe ys,ta ke
re gular breaks in good time that allow for ade-
qu ate recuperation.
Yo u can choose between two settings:

R Sensitiv

is wa rned earlier and the attention le vel de tec- te

If dr owsiness or increasing lapses in concent ra-
tion are de tected, theATTENTION ASSIST: Take
a break! warning appears in the Instrument Dis-
pla y.Yo u can ackno wledge the message and take
a break where necessar y.Ifyo u do not take a
break and ATTENTION ASSIST continues todetect
increasing lapses in concentration, you will be
wa rned again aTer a minimum of 15 minutes. Yo

If AT TENTION ASSIST is unable tocalculate the
attention le vel and cannot issue a warning, the
System suspended message appears.
If a warning is given in the Instrument Displa y,the
multimedia system o.ers tosear chfor a rest
area. You can select a rest area and start naviga-
tion tothis rest area. This function can be acti va-

When Active Distance Assist DISTRONIC is acti va-
te d, theve hicle speed will be adap ted accordingly
to thero ute events ahead. Depending on the drive
prog ram selected, theve hicle neg otiates a route
ev ent ahead in an economical, comfor table or
dynamic manner. When thero ute event has been
passed, theve hicle accelerates again tothe
stored speed. The set distance totheve hicle in
front, vehicles de tected ahead and speed restric-
tions ahead are take n into account.
Yo u can activate and deactivate route-based
speed adap tation in the multimedia system
(/ page 248).
The following route events are take n into account:
R Bends R
T-junctions, roundabouts and toll stations
R Turns and exits
R Tra1c jams ahead (only with Live Tra1c Infor-
mation )
% When theto ll station is reached, Active Dis-
ta nce Assist DISTRONIC ado ptsth e speed as

Also, the speed is reduced if the turn signal indi-
cator tochange lanes is switched on and one of
th efo llowing situations is de tected:
R Turning o. at junctions
R Driving on slowing-down lanes
R Driving on lanes adjacent toslowing-down
lanes
The driver is responsible forch oosing theright
speed and observing other road users. This
applies in particular tojunctions, roundabouts and
tra1c lights, as route-based speed adap tation
does not brake theve hicle toa standstill.
When route guidance is active, the /rst speed
adjustment is car ried out automaticall y.Ifth e turn
signal indicator is switched on, the selected route is con/rmed and fur
ther speed adjustment is acti-
va ted.
Speed adap tation is cancelled in thefo llowing
cases:
R Ifth e turn signal indicator is switched o.
before thero ute event.
R Ifth e driver depresses the accelerator or
brake pedal during the process.
