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

The braking e.ect of the electric mo tor during

may not be available at all in thefo llowing situa-

increases
R ifth e high-voltage battery is not yet at a nor-

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

time. You must be ready tobrake at all times ir re-
specti veof whe ther the system is active.

% IfTra1c Sign Assist does not de tect a maxi-

The maximum limit speed set bythe /r stpoint

The limit speed set bythe /rst point of resis tance

If yo u depress the accelerator pedal be yond the

pedal is before the /r stpoint of resis tance again,
th e limit speed will be reactivated, thus making
sure that the maximum permissible speed is main-

cle todecelerate, release the accelerator pedal.
How much theve hicle will decelerate automati-
cally when the accelerator pedal is released
depends on the set recuperation le vel
( / page 158). In hÃ, deceleration will be
automatic where there are vehicles in front, tra1c
signs, roundabouts and bends. In all other recu-
peration le vels, a permanently de/ned overrun
