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 youta ke your foot o. the accelerator
pedal when theve hicle is in motion and in trans-
mission position h,recuperation in overrun
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 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
Syst em limits em limits
The braking e.ect of the electric mo tor during
re cuperation in overrun mode may be reduced or
may not be available at all in thefo llowing situa-
tions:
R when the high-voltage battery charge level
increases
R ifth e high-voltage battery is not yet at a nor-
mal operating temp erature
In these cases, the desired deceleration is set by

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 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,

R Ifth e speed stored in the limiter is higher than
th e limit speed of Í,theve hicle will accel-

be yond the /rst point of resis tance. If you
depress the accelerator pedal be yond the sec-
ond point of resis tance (kickdown), theve hicle
will continue toaccelerate without any limi ta-

R Ifth e speed stored bythe limiter is lo werth an
