ECO Assist analyses data for the vehicle's expec‐
ted route. This allows the system to optimally
adjust the driving style for the route ahead, save
fuel and recuperate. If the system detects an
event ahead, e.g. a speed limit or a roundabout,
it will appear on the multifunction display 1.
The following symbols can be displayed:
Not all events can be displayed, depending on the
engine type.
1 Event ahead
2 Distance to the event ahead
3 "Foot off the accelerator" prompt
A different number of segments
around the symbol depending on the distance to
the event ahead:
Few segments: the event ahead is near.
R
Many segments: the event ahead is further
R
away.
When the vehicle nears the event, ECO Assist
will calculate the optimal speed for maximum
fuel economy and recuperative energy based on
the distance, speed and downhill gradient. The
Foot off the accelerator
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
erator prompt, the segments will remain white.
The event will be shown for a short time after it
has been passed.
2 will appear
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
prompt.
