symbol will be displayed in grey.

run mode will be initiated. If the deceleration is
not sufficient, also apply the service brake.

cannot identify any further recommendations
from the route ahead.

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 there is dirt on the windscreen in the vicinity
R
of the multifunction camera or if the camera is
misted up, damaged or obscured.
If the traffic signs are hard to detect, e.g. due
R
to dirt, snow or insufficient lighting, or
because they are covered.
