If th e calculated route is adhered towhen route
guidance is active, ECO Assist will operate with
gr eater accuracy. The basic function is also availa-
ble without active route guidance. Not all informa-
tion and tra1c situations can be fore seen. The
qu ality 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 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 in the area of the multifunc-
tion camera is dirty, or if the camera is misted
up, damaged or co vered. R
Ifth era dar sensors are dirty or damaged.
R Ifth e tra1c signs are hard todetect, e.g. due
to dirt, snow or insu1cient lighting, or
because they are co vered.
R Ifth e information in the navigation system's
digital map is incor rect or out-of-date.
R If signs are ambiguous, e.g. road signs in road-

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 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 Only charge the high-voltage battery with
direct cur rent (mode 4) if necessar y.
R If leaving theve hicle idle for lengt hyperiods,
park up theve hicle with a high- voltage battery
ch arge leve l between 25% and 30%. 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 258).
R Char gethe high-voltage battery if thech arge
le ve l is below 15%.
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.

(mode 2, 3 or 4):
R Charging through recuperation while theve hi-
cle is in motion
R Charging with alternating cur rent when sta-

- at a mains soc ket (mode 2)
- at a wallbox or charging station (mode 3)
R Charging with direct cur rent when stationary
(vehicles with combo vehicle soc kets):
- at a fast charging station (mode 4)
Depending on the count ry-speci/c vehicle equip-
ment and your vehicle's charging cable, single
phase ACcharging is also possible.
Obser vethe di.erent grid requ irements of your
cur rent location when charging. Only use charging
cables which conform tothegr id requiremen ts.
Consult a quali/ed elect rician 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
