180 Driving and parking
The segments of distance display
distance to the event ahead as follows:
A few segments light up: the event ahead is
R
near.
Many segments light up: the event ahead is
R
further away.
When the vehicle nears an event, ECO Assist will
calculate the optimal speed for maximum fuel
economy and recuperative energy based on the
distance, speed and gradient. "Foot off the accel-
erator" symbol 3 will appear on the instrument
display.
If you take your foot off the accelerator pedal in
good time, the remaining segments on the display
will successively turn green until the event shown
is reached. The drivetrain will be set for maximum
fuel economy. In drive program = with the
drive setting "Reduced" or "Moderate", the vehicle
will coast, with the combustion engine switched
off if necessary.
If there is no response to the prompt, the seg-
ments will remain white.
2 show the The event will be shown for a short time after it
has been passed.
If the event involves a vehicle in front and when
the coast-down recommendation is given, all seg-
ments will immediately turn green once there is a
response to the "Foot off the accelerator" prompt
3.
If the system does not intervene during the event
ahead, nothing will be displayed. The system will
be passive.
In drive program A, only the event "Vehicle in
front" is displayed.

ECO Assist can function even more precisely if
the route is adhered to when route guidance is
active. The basic function is also available without
active route guidance. Not all information and
traffic situations can be foreseen. The quality
depends on the map data.
ECO Assist is only an aid. The driver is responsible
for keeping a safe distance from 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 visibility is poor, e.g. due to insufficient illu-
R
mination of the road, highly variable shade
conditions, rain, snow, fog or heavy spray.
If there is glare, e.g. from oncoming traffic,
R
direct sunlight or reflections.
If there is dirt on the windscreen in the area of
R
the multifunction camera or the camera is
misted up, damaged or obscured.
If road signs are hard to detect, e.g. due to
R
dirt, snow or insufficient lighting, or because
they are obscured.
If the information on the navigation system's
R
digital map is incorrect or out of date.
If signs are ambiguous, e.g. road signs in road-
R
works or in adjacent lanes.
