beside the transmission displa y.
When theve hicle nears an event, ECO Assist will
calculate the optimal speed for maximum fuel
economy and recuperati veenergy based on the
dis tance, speed and downhill gradient. The "Foot
off the accelera tor" 3 symbol will appear on
th e multifunction displa y.
If th e driver lifts off the accelera tor pedal in
good time, there maining segments on the dis‐

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 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 Ifth ere is poor visibility, e.g. due toinsuf fi‐
cient illumination of thero ad, high lyvariable
shade conditions, rain, sno w,fog or heavy

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 traf fic signs are ha rdtodetect, e.g. due
