ECO Assist can function even more precisely if
th ero ute is adhered towhen routeguidance 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

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digital map is incor rect or out of date.

Depending on the selected recuperation le vel,the
electric mo tor on there ar axle is operated as an
alternator when in overrun mode and during brak-
ing in order tocharge the high-voltage battery
while driving. As soon as youta ke your foot o. the
accelerator pedal when theve hicle is in motion
and in transmission position h,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 deceleration in overrun mode may not be suf-
fi cient depending on the driving conditions.
Decelerating toa standstill is not possible. Also
brake with the service brake if necessar y.Alw ays
adapt your speed tothe driving conditions and
ke ep a su1cient distance.
The recuperative brake system has thefo llowing
ch aracteristics:
R supports braking with elect ronically cont rolled
brake forc e 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 cannot be reco vered. The
more you drive and brake in an anticipatory
manner, the more e1cient lyenergy can be
re cuperated.
Syst

The braking e.ect of the electric mo tor during

may not be available at all in thefo llowing situa-

increases
