injury or danger tolife. #
Never lea vepersons, children in partic‐

Dep ress the brake pedal and push the
DIRECT SELECT le ver down past thefirst
point of resis tance. Fu
nction of flexible all-wheel distribution
The flex ible all-wheel distribution means the
drive is alw ays ideally distributed between the
two axles. Depending on the situation, only the
front axle or only there ar axle can be driven, or
th e drive can be distributed continuously
between bo thaxles.
This allo ws the maximum recur rent delay tobe
achie ved (/ page149). The resulting recupera‐
tion increases theve hicle's range.
To get her with ESP ®
and 4ETS, theflex ible all-
wheel distribution impr ovesth e traction of your
ve hicle whene ver a driven wheel spins due to
insuf ficient traction.
If yo ufa ilto adapt your driving style, theflex ible
all-wheel distribution can neither reduce therisk
of accident nor override the la wsof ph ysics. It
cannot take into account road, weather or traf fic
conditions. The flex ible all-wheel distribution is only an aid.
You are responsible especially for
maintaining a safe dis tance from theve hicle in
front, forve hicle speed, for braking in good time
and forst ay ing in lane.
% In wint ryroad conditions, the maximum
ef fect of theflex ible all-wheel distribution
can be achie ved only if you use winter tyres
(M+S tyres), with sn ow chains if necessar y. Cha

TEHigh-vol tage battery damage due
to leaving theve hicle idle for lengt hy
periods of time Lithium-ion batteries
experience a natural
self-dis charge.
Exhaustive discha rging can therefore occur if
th eve hicle is idle for se veral mon ths. This
can damage the high-voltage batter y. #
Toavo id damage, please obser vethe
fo llowing recommendations when han‐
dling the high-voltage batter y. *

TEAccelerated ageing of the high-
vo ltage battery As a
result of its basic characteristics, the
st orage capacity of and the amount of energy
av ailable from the high-voltage battery
decreases overth e course of its life. There‐
fo re , bo th th e maximum electrical range that
can be achie vedby theve hicle and its maxi‐
mum electrical output can be impaired.
The following factors can accele rate the age‐
ing of the high-voltage battery:
R frequently fully charging (char gelevel
10 0%) the high-voltage batter y,especially
when this process is not directly follo wed
by a journey
R frequent rapid charging with direct cur‐
re nt (mode 4)
R leav ing theve hicle non-operational for
long periods at high ambient temp era‐
tures #
Toavo id accelerated ageing, please
obser vethefo llowing recommendations
when handling the high-voltage batter y. Driving and pa

Re
commendations when handling the high-volt‐
age battery:
R Every six months, when the outside temp era‐
ture is abo ve10 °C, park theve hicle over‐
night with a charge leve l below 30%.
R Only charge the high-voltage battery with
direct cur rent (mode 4) if necessa ry.
R Char gethe high-voltage battery on average
to ach arge leve l of 80%. Be yond a charge
le ve l of 80%, thech arging time is considera‐
bly prolon ged.
R If leaving theve hicle idle for lengt hyperiods,
park up theve hicle with a high-voltage bat‐
te ry charge leve l between 30% and 50%. Do
not keep the high-voltage battery continu‐
ously connected topowe r supp lyequipment.
R If leaving theve hicle idle for lengt hyperiods
of time avoid, if possible, high ambient tem‐
peratures.
R Check the high-voltage battery's le vel of
ch arge every six weeks.
R Charge the high-voltage battery if thech arge
le ve l is below 20%. R
Do not disconnect the12 V battery even if
th eve hicle is left idle for a lengt hyperiod.
Otherwise, the condition of theve hicle's
high-voltage battery cannot be monitored.
Yo u can cont ribute toreducing theve hicle's
energy consum ption in thefo llowing ways:
R An anticipatory driving style (/ page155)
R Reduced use of elect rical consumers
R Having theve hicle regularly maintained
The charging time of the high-voltage battery
may change overth e course of its life.
% Depending on the national version, your
ve hicle is equipped with one of thefo llowing
ve hicle soc kets.
Yo u can charge the high-voltage battery with
bo th alternating cur rent (mode or 2/3) and
di re ct cur rent (mode 4). Combo 1

Charging options forth e high-voltage battery
(mode 2, 3 or 4):
R Charging thro ugh recuperation while the
ve hicle is in motion
R Charging with alternating cur rent when sta‐
tionary:
- Ata mains outlet (mode 2)
- Atawa llbox or charging station (mode 3)
R Charging with direct cur rent when stationary:
- Atafa st charging station (mode 4)
Depending on the count ry-specific vehicle equip‐
ment and your vehicle's charging cable, sin gle
phase ACcharging is also possible.
Obse rveth e dif fere nt grid requirements of your
cur rent location when charging. On lyuse charg‐
ing cables which con form tothe grid require‐
ments. Consult a qualified electrician or your
local grid operator if you ha veany questions.
It is recommended that youch arge the high-volt‐
age battery at a wallbox or charging station due to
the impr ovedch arging per form ance and bet‐
te rch arging ef ficiency of fere d.
Sy stem limits
The po wer output of the high-voltage battery
may be impaired bythefo llowing:
R High or low outside temp eratures
R Elect rical auxilia ryconsumers in theve hicle
being switched on, e.g. operating the air con‐
ditioning sy stem
R Exte nded pe riods without charging
The charging time of the high-voltage battery
may be increased bythefo llowing:
R High or low outside temp eratures
R Exte nded pe riods without charging
R The maximum available charge cur rent of the
ch arging facility
R The settings of thech arging process in the
