fuel and recuperate. If the system detects an
event ahead and the vehicle nears the event, ECO
Assist will calculate the optimum speed for maxi-
mum fuel economy and recuperative energy
based on the distance, speed and downhill gradi-
ent.
If the deceleration provided by ECO Assist is not
sufficient, you must also brake with the service
brake. This is especially the case if, for example,
you pull away again in slow-moving traffic and the
distance to the vehicle in front is very short.
1 "Foot off the accelerator" recommendation
2 Route event ahead
If a route event or vehicle that requires an adjust-
ment of your driving style for more efficiency is
detected ahead, corresponding symbol
the ý symbol (grey) will be displayed.
If you release the accelerator pedal, the ý
symbol will turn green and recuperation in over-
run mode will be initiated. If the deceleration is
not sufficient, also apply the service brake. If ECO
Assist intervenes for a route event ahead (not for
a vehicle in front) and you then press the acceler-
ator pedal again, you end ECO Assist's control.
The ECO Assist display is hidden again in the fol-
lowing cases:
You do not react to the ECO Assist recommen-
R
dation for a long time.
You press the accelerator pedal while ECO
R
Assist is intervening for a route event ahead
(not for a vehicle in front).
ECO Assist cannot identify any further recom-
R
mendations from the route ahead.
In addition to a vehicle in front ¥, ECO Assist
can detect the following route events

ing on the vehicle's equipment:
~ Roundabout
¡ S-bend
¢ Sharp bend
£ T-junction
¤ Downhill gradient
¦ Speed limit
%
In drive program A, ECO Assist only reacts
to the route event "Vehicle in front".
System limits
If the calculated route is adhered to when route
guidance is active, ECO Assist will operate with
greater accuracy. The basic function is also availa-
ble without active route guidance. Not all informa-
tion 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.
