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 will end control by ECO
Assist.
The ECO Assist display will be hidden again in the
following cases:
You do not react to the ECO Assist recommen-
R
dation for a long time.
You depress 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.
Depending on equipment, ECO Assist will detect
following route events
cle 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.
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 the windscreen is dirty in the vicinity of the
R
multifunction camera.
If the multifunction camera is misted up, dam-
R
aged or obscured.
