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
available without active route guidance. Not all
information and traffic situations can be fore‐
seen. The quality depends on the map data.
ECO Assist is only an aid. The driver is responsi‐
ble 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 there is poor visibility, e.g. due to insuffi‐
R
cient 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 area of the
R
multifunction camera, or if the camera is fog‐
ged up, damaged or covered.
If the traffic signs are hard to detect, e.g. due
R
to dirt, snow or insufficient lighting, or
because they are covered.
If the information in the navigation system's
R
digital map is incorrect or out-of-date.
If the signs are ambiguous, e.g. road signs in
R
roadworks or in adjacent lanes.
