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

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

of time Lithium-ion batteries
experience a natural self-

Exhausti vedischarging can therefore occur if

TE Accelerated ageing of the high-volt-
age battery As a
result of its basic characteristics, the
storage capacity of, and the amount of energy
av ailable from, the high-voltage battery
decreases over the course of its life. Due to
th is, bo th the maximum electrical range that
can be achie vedby theve hicle and its maxi-
mum elect rical output can be impaired.
The following factors could accelerate the age-
ing of the high-voltage batter y:
R frequently fully charging (char gelevel
100%) the high-voltage batter y,especially
when this process is not directly follo wed
by a jou rney
R frequent rapid charging with direct cur rent
(mode 4)
R leaving theve hicle idle for lengt hyperiods
at high ambient temp eratures #
Toavo id accelerated ageing, please
obser vethefo llowing recommendations
when handling the high-voltage batter y. Re
commendations when handling the high-voltage
batter y:
R Every six months, when the outside temp era-
ture is abo ve10 °C, park theve hicle overnight
with a charge leve l below 20%.
R Only charge the high-voltage battery with
direct cur rent (mode 4) if necessar y.
R Char gethe high-voltage battery on average to
a ch arge leve l of 80%. Be yond a charge leve l of
80%, thech arging time is considerably pro-
lon ged.
R If leaving theve hicle idle for lengt hyperiods,
park up theve hicle with a high- voltage battery
ch arge leve l between 30% and 50%. Do not
ke ep the high-voltage battery continuously
connected topowe r supply equipment.
R If leaving theve hicle idle for lengt hyperiods of
time avoid, if possible, high ambient temp era-
tures.
R Check the high-voltage battery's charge level
ev ery six weeks (/ page 180).
R Char gethe high-voltage battery if thech arge
le ve l is below 20%. R
Do not disconnect the 12 V battery even if the
ve hicle is leT idle for a lengt hyperiod. Other-
wise, the condition of theve hicle's high- volt-
age battery cannot be monitored.
Yo u can contribute toreducing theve hicle's
ene rgy consum ption in thefo llowing ways:
R An anticipatory driving style (/ page 154)
R Reduced use of electrical consumers
R Having theve hicle regula rly main tained
The charging time of the high-voltage battery may
