Dynamic Select Switch - Mercedes-Benz S-Class Owner's Manual

Foot off the accelerator message will appear on
the multifunction display. If the driver lifts off the
accelerator pedal in good time, the remaining
segments on the display will turn green until the
event shown is reached. The drivetrain will be
set for maximum fuel economy. The vehicle will
coast, with the combustion engine switched off
if necessary, and recuperate on its own using
the electric motor. Recuperation will charge the
battery.
If there is no response to the Foot off the accel-
erator prompt, the segments will remain white.
The event will be shown for a short time after it
has been passed.
If the event involves a vehicle ahead and when
the coast-down recommendation is given, all
segments will immediately turn green once there
is a response to the Foot off the accelerator
prompt.
For Active ECO Assist in drive program ;,
symbol 3 will appear on the multifunction dis‐
play and on the head-up display beside transmis‐
sion position h. Symbol 3 will also appear
when the assistant display is not selected.
ECO Assist is active only in drive programs ;
and A.
System limitations
ECO Assist can function more precisely if the
route is maintained when route guidance is
active. The basic function is also available with‐
out active route guidance. Not all information
and traffic situations can be foreseen. The qual‐
ity depends on the map data.
ECO Assist is only an aid. The driver is responsi‐
ble for keeping a safe distance to the vehicle in
front, for vehicle speed and for braking in good
time. The driver must be ready to brake at all
times irrespective of whether the system inter‐
venes.
The system may be impaired or may not function
in the following situations:
If there is poor visibility, e.g. due to insuffi‐
R
cient illumination of the road, highly variable
shade conditions, or due to rain, snow, fog or
heavy spray.
If there is glare, e.g. from oncoming traffic,
R
direct sunlight or reflections.
Driving and parking 203
If there is dirt on the windscreen in the vicin‐
R
ity of the multifunction camera or the camera
is misted up, damaged or obscured.
If the traffic signs are hard to detect, e.g. due
R
to dirt or snow or insufficient lighting, or
because they are covered.
If the information on the navigation system's
R
digital map is incorrect or out of date.
If the signs are ambiguous, e.g. traffic signs
R
on construction sites or in adjacent lanes.
