When Dis
tance Assi stDISTRONIC is acti ve,the
function adju ststh e speed depending on the
ro ute events ahead. Depending on the drive pro‐
gram selected, theve hicle negotiates thero ute
eve nt ahead in a fuel-s aving, com fortable or
dynamic manner. When thero ute event has been
passed, theve hicle accelerates again tothe
st ored speed. The set dis tancetotheve hicle in
front, vehicles de tected ahead and speed restric‐
tions ahead are take n into account.
Ro ute-based speed adjustment can byconfig‐
ured in the multimedia sy stem (→ page 208).
Ro ute events ahead are:
R Bends
R T-junctions, roundabouts and tollst ations
R Turns and exits
R Traf fic jams ahead (only wi thLive Traf fic
( → page 321))
% When theto llst ation is reached, Active Dis‐
ta nce Assi stDISTRONIC adopts the speed as
th estored speed. Also,
the speed is reduced if the turn signal to
ch ange lanes is swit ched on and one of thefo l‐
lowing situations is de tected:
R Turning off 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 traf fic lights, as route-based speed adap ta‐
tion does not brake theve hicle toast andstill.
When route guidance is active, thefirs t speed
adjustment is car ried out automaticall y.Ifthe
turn signal indica tor is switched on, the selected
ro ute is confirmed and fur ther speed adjustment
is activated.
Speed adjustment is cancelled in thefo llowing
cases:
R Ifth e turn signal indicator is switched off
before thero ute event.
R Ifth e driver depresses the accelera tor or
brake pedal during the process. Sy
stem limitations
Ro ute-based speed adap tation does not take
ri ght of wayre gulations into account. The driver
is responsible for complying with road traf fic
re gulations and driving at a suitable speed.
In dif ficult conditions (e.g. unclear roads, nar row
lanes, wetro ad sur faces, snow or ice) or when
driving wi tha trailer, the speed adjustment made
by the sy stem may not alw ays be suitable. In
th ese situations the driver must inter vene
acco rding ly. &
