ECO Assist function
%
The following function is country-dependent
and available only in conjunction with an
integrated navigation system.
ECO Assist is active only in drive programs
A, Î, Ï and ;, and only in trans‐
mission positions h or hÃ. Permanent
manual gearshifting p must be switched off
(see the vehicle Operator's Manual).
ECO Assist analyzes 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, it will appear on the multifunction
display.
The following events can be detected and dis‐
played for the route section ahead:
R
Vehicle in front
R
Speed limit
R
Downhill and uphill gradient
R
Intersections and traffic circles
R
Bends
1
Event ahead, e.g. traffic circle
2
Distance to the event ahead
3
"Foot off the accelerator" prompt
A different number of segments 2 will light up
depending on the distance to the event ahead:
R
A few segments: the event ahead is near.
R
Many segments: the event ahead is further
away.
If ECO Assist is active, "Foot off the accelerator"
symbol 3 will appear on the multifunction dis‐
play and on the head-up display beside the
transmission position display.
When the vehicle nears an event, ECO Assist will
calculate the optimal speed for minimal energy
consumption based on the distance, speed and
downhill gradient. "Foot off the accelerator"
symbol 3 will appear on the multifunction dis‐
play.
If the driver lifts off the accelerator pedal in
good time, the remaining segments on the dis‐
play will successively turn green until the event
shown is reached. The drivetrain will be set for
minimal energy consumption. The vehicle will
recuperate autonomously and thus charge the
battery.
