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‐
play will turn green until theev ent shown is
re ached. The driv etra in will be set for maximum

combustion engine switched off if necessar y,
and recuperate on its own using the electric

white.
The event will be shown for a short time af ter it
has been passed.
If th eeve nt in volves a vehicle ahead and when
th e coast-down recommendation is given, all

If th e sy stem does not inter vene du ring the

ECO Assist is active only in drive program ;
(maximum recuperation) and A(reduced

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