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 the 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. The driver must be ready tobrake at all times, ir
respecti veof whe ther the system inter-

The system may be impai red or may not function
in thefo llowing situations:
R If visibility is poor, e.g. due toinsu1cient illu-

conditions, rain, sno w,fog or heavy spr ay.
R Ifth ere is glare, e.g. from oncoming tra1c,

Depending on the selected recuperation le vel,the
electric mo tor is operated as an alternator when
in ove rrun mode and during braking in order to
ch arge 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 deceleration in overrun mode may not be suf-
fi cient depending on the driving conditions.
Decelerating toa standstill is not possible. Also
brake with the service brake if necessar y.Alw ays
adapt your speed tothe driving conditions and
ke ep a su1cient distance.
The recuperative brake system has thefo llowing
ch aracteristics:

over the course of its life. As a
re sult, the maximum electrical range that can
be achie vedby theve hicle is reduced and its
maximum electrical output can be impaired.
The following factors could accelerate the age-
ing of the high-voltage batter y:
R a high le vel of charge , especially if the
ve hicle is idle for a lengt hyperiod of time
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 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 225).
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 192)

Depending on the count ry-speci/c vehicle equip-

cables which conform tothegr id requ irements.
Consult a quali/ed electrician or your local grid
operator if you ha veany questions.
It is recommended that youch arge the high-volt-
