Depending on the selected recuperation le vel,the
electric mo tors are operated as an alternator when in
overrun mode and during braking in order
to charge the high-voltage battery while driving.
As soon as youre lease the accelerator pedal
when theve hicle is in motion, recuperation in
ove rrun mode is initiated.
The higher there cuperation, the more sharply the
ve hicle is braked when coasting and the more
electrical energy is fed into the high-voltage bat-
te ry.
The rege nerative brake system has thefo llowing
ch aracteristics:
R supports braking with elect ronically cont rolled
brake force boosting
R con verts th e kinetic energy of theve hicle into
elect ric energy
% Ifyo u brake hard, the mechanical brake is
also used. This means that the maximum
re cuperative energy cann otbe reco vered. The
more you drive and brake in an anticipatory
manner, the more e1cient lyenergy can be
re cuperated. Driving and parking

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

energy consum ption. The vehicle will recuperate
autonomously and thus charge the high-voltage

If th ere is no response to"Foot o. the accelera-

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 theav ailable 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. You must be ready tobrake at all times ir re-
specti veof whe ther the system is active.
The system may be impaired or may not function
in thefo llowing situations:
R Ifth ere is poor visibility, e.g. due toinsu1cient
illumination 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 e windscreen is dirty in the vicinity of the
multifunction camera.
R Ifth e multifunction camera is misted up, dam-
aged or obscured.
R Ifro ad signs are hard todetect, e.g. due to
dirt, snow or insu1cient lighting, or because

R Ifth e digital road map of the navigation sys-
te m has incor rect or outdated information.
R If signs are ambiguous, e.g. road signs in road-
wo rks or in adjacent lanes.
