smaller scale. The objects in view are in fact
closer than they appear.
As a result, you may misjud gethe dis tance
between you and thero ad user driving
behind you, e.g. when changing lanes. #
Therefore, alw ays look over your shoul‐

Sy stem limitations
ECO Assist can function more precisely if the
ro ute is main tained when route guidance is
active. The basic function is also available with‐
out active route guidance. Notall information
and traf fic situations can be fore seen. The qual‐
ity depends on the map data. ECO Assist is only an aid. The driver is
responsi‐
ble forke eping a safe dis tance totheve hicle in
front, forve hicle speed and for braking in good
time. The driver must be ready tobrake at all
times ir respective of whe ther the sy stem inter‐
ve nes.
The sy stem may be impaired or may not function
in thefo llowing situations:
R If visibility is poor (e.g. due toinsuf ficient illu‐
mination of thero ad, high lyvariable shade
conditions, rain, sno w,fog or heavy spr ay).
R Ifth ere is glare (e.g. from oncoming traf fic,
di re ct sunlight or reflections).
R Ifth ere is dirt on the windscreen in the vicin‐
ity of the multifunction camera or the camera
is mis ted up, damaged or obscured.
R Ifth e tra ffic signs are hard todiscern (e.g.
due todirt or snow or insuf ficient lighting, or
because they are obscured).
R Ifth e information on the navigation sy stem's
digital map is incor rect or out of da te.
R Ifth e signs are ambiguous (e.g. traf fic signs
