and the ý symbol will be
displayed in gray.
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:
~ Traffic circle
¢ Sharp bend
& Intersection
£ T-intersection
¤ Downhill gradient
* Speed limit
%
In drive program A, ECO Assist reacts only
to the "Vehicle in front" route event .
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.

depend-
The system may be impaired or may not function
in the following situations:
If there is poor visibility, e.g. due to insufficient
R
illumination 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 windshield is dirty in the vicinity of the
R
multifunction camera.
If the multifunction camera is fogged up, dam-
R
aged 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 digital road map of the navigation sys-
R
tem has incorrect or outdated information.
If signs are ambiguous, e.g. road signs in road-
R
works or in adjacent lanes.
If the radar sensors are dirty or obscured.
R
When you drive on roads with steep uphill or
R
downhill gradients.
If there are narrow vehicles in front, such as
