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‐

ECO Assist is only an aid. The driver is responsi‐
ble forke eping a safe dis tance from theve 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 venes.
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,
