If
yo uta ke your foot o. the accelerator pedal in
good time, there maining segments on the display
will successively turn green until theeve nt sh own
is reached. The driv etra in will be set for minimal
energy consum ption. The vehicle will recuperate
autonomously and thus charge the batter y.
% You can also manually increase or reduce the
re cuperation in drive prog ram Î. Ho wever,
ECO Assist is available only in thehÃ
setting (/ page 169).
If th ere is no response tothe "Foot o. the accel-
erator" prom pt3 ,th e segments will remain
white.
The event will be shown for a short time aTer it
has been passed.
If th eev ent in volves a vehicle in front, the symbol
will be shown in green as soon as there is a
re sponse to"Foot o. the accelerator" prom pt3 .
If th e system does not inter vene during theev ent

ECO Assist can function even more precisely if
th ero ute is adhered towhen route guidance is
active. The basic function is also available without
active route guidance. Not all information and
tra1c situations can be fore seen. The quality
depends on the map data.
ECO Assist is only an aid. The driver is responsible
fo rke eping a safe distance from theve hicle in
front, forve hicle speed and for braking in good
time. The driver must be ready tobrake at all
times ir respecti veof whe ther the system inter-
ve nes.
The system may be impai red or may not function
in thefo llowing situations:
R If visibility is poor, e.g. due toinsu1cient illu-
mination of thero ad, highly variable shade
conditions, rain, sno w,fog or heavy spr ay.
R Ifth ere is glare, e.g. from oncoming tra1c,
direct sunlight or re0ections.
R Ifth ere is dirt on the windscreen in the area of
th e multifunction camera or the camera is
misted up, damaged or obscured. R
Ifro ad signs are hard todetect, e.g. due to
dirt, snow or insu1cient lighting, or because
th ey are obscured.
R Ifth e information on the navigation system's
digital map is incor rect, insu1cient or out of
date.
R If signs are ambiguous, e.g. road signs in road-
wo rks or in adjacent lanes. F F

The following function is countr y-dependent
and available only in conjunction with an inte-
gr ated navigation system.
The route-based operating-mode strategy is active
only in drive prog rams A and;. When
ro ute guidance is active, data on the planned
ro ute is anal ysed. This function can be activated
and deactivated in the multimedia system
(/ page 292).
If th e function is active, data on the fur ther course
of thero ute is evaluated. This includes, e.g. road
