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

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-

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
R when driving at speeds close tozero
R in transmission position i

In these cases, the desired deceleration is set by

will successively turn green until theeve nt sh own

autonomously and thus charge the high-voltage

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

The 0exible all-wheel distribution of the 4MATIC
means the drive is alw ays ideal lydist ributed
between bo thaxles. Depending on the situation,
only the front axle or only there ar axle can be
driven, or the drive can be distributed continu-
ously between bo thaxles.
This means that recuperation can be used even
more e.ectively and thera nge of theve hicle can
be increased (/ page 155).
To get her with ESP ®
and 4ETS, 4MATIC impr oves
th e traction of your vehicle whene ver a driven
wheel spins due toinsu1cient traction.
If yo ufa ilto adapt your driving style, 4MATIC can
neither reduce therisk of an accident nor override
th e la wsof ph ysics. It cannot take into account
ro ad, weather or tra1c conditions. 4MATIC is only
an aid. You are responsible especially for main-
ta ining a safe distance from theve hicle in front, fo
rve hicle speed, for braking in good time and for
st ay ing in lane.
% In wintry road conditions, the maximum e.ect
of the 0exible all-wheel distribution can be
achie ved only if you use winter tyres (M+S
tyres), with snow chains if necessar y. Char
