eve nt ahead, e.g. a speed limit or a roundabout,
it will appear on the multifunction displa y.The
fo llowing symbols can be displa yed: Not all

A di fferent number of segments 2will light up
around the symbol depending on the dis tance to

The "Foot off the accelerator" symbol 3will

bol
3will also appear on the head-up display
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
fuel econom y.The vehicle will coast, with the
combustion engine switched off if necessar y,
and recuperate on its own using the electric
mo tor.Re cuperation will charge the batter y.
If th ere is no response tothe "Foot off the accel‐
erator" 3prom pt,th e segments will remain
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
segments will immediately turn green once there is a
response tothe "Foot off the accelerator"
3 prom pt.
If th e sy stem does not inter vene du ring the
eve nt ahead, no thing will be displa yed. The sys‐
te m is passive.
ECO Assist is active only in drive program ;
(maximum recuperation) and A(reduced
re cuperation).
Ve hicles with a 48 V on-board electrical sys‐
te m (EQ Boo sttech nology): in drive program
A, only theeve nt "Vehicle ahead" is dis‐
pl ay ed.
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
