When
theve hicle nears an event, ECO Assist will
calculate the optimal speed for minimal energy
consum ption based on the distance and speed.
"Foot o. the accelerator" recommendation 3will
appear on the inst rument displa y.
If yo uta ke your foot o. the accelerator pedal in
good time, there maining segments on the display
will successively turn green until theeve nt sh own
is reached. The driv etra in will be set for minimal
energy consum ption. The vehicle will recuperate
autonomously and thus charge the high-voltage
batter y.
% You can also manually increase or reduce
re cuperation. Ho wever, ECO Assist is availa-
ble only in thehà setting (/ page 156).
If th ere is no response to"Foot o. the accelera-
to r" recommendation 3,the segments will
re main white.
The event will be shown for a short time aTer it
has been passed.
If th eev ent in volves a vehicle in front, all seg-
ments will immediately turn green once there is a
re sponse to"Foot o. the accelerator" prom pt3 . If ECO Assist cann
otidentify a recommendation
fo r adjusting the driving style forth eev ent ahead,
no thing will be displa yed. The system will be pas-
sive.

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
Ifth e windscreen is dirty in the vicinity of the
multifunction camera.
R Ifth e multifunction camera is misted up, dam-
aged or obscured.
R Ifro ad signs are hard todetect, e.g. due to
dirt, snow or insu1cient lighting, or because
th ey are obscured.
R Ifth e digital road map of the navigation sys-
te m has incor rect or outdated information.
R If signs are ambiguous, e.g. road signs in road-
wo rks or in adjacent lanes.
R Ifth era dar sensors are dirty or obscured.
R When you drive on roads with steep uphill or
downhill gradients.

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
ch ange overth e course of its life.
% Depending on the national version, your vehi-
cle is equipped with one of thefo llowing vehi-
cle soc kets.
Yo u can charge the high-voltage battery with
bo th alternating cur rent (mode 2/3) and
direct cur rent (mode 4). 164
