ECO Assist can function even more precisely if
th ero ute is adhered towhen 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‐

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

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‐
