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-
ve nes.
The system may be impai red or may not function
in thefo llowing situations:
R If visibility is poor, e.g. due toinsu1cient illu-
mination 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 ere is dirt on the windscreen in the area of
th e multifunction camera or the camera is
misted up, damaged 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 information on the navigation system's
digital map is incor rect, insu1cient or out of
date.

The route-based operating-mode strategy is active
only in drive prog rams A and;. When
ro ute guidance is active, data on the planned

and deactivated in the multimedia system
(/ page 301).
If th e function is active, data on the fur ther course
of thero ute is evaluated. This includes, e.g. road
type, speed limi tations and altitude data. The
hybrid system then adapts the operating
strategy tothe fur ther course of thero ute:
R Use of electrical energy and the combustion
engine are adap ted.
R State of charge ofthe high-voltage battery is
controlled accordingl y.
R Electrical energy is reser ved especially for
electric mode, e.g. urban route sections.
R The vehicle automatically selects the operat-

R Drive prog ram ; is selected.
R The speed is within a suitable range.
R The road's course is suitable, e.g. no steep
uphill or downhill inclines or tight bends.
R There is no trailer hitched up tothe trailer
hitch, and no bicycle rack Fitted.
R You do not depress the accelerator or brake
pedal (e xcept for light brake applications).

4MATIC ensu resth at all four wheels are driven.
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. 4MATIC cannot take account
of road, weather and tra1c conditions. 4MATIC is
only an aid. You are responsible especially for
maintaining a safe distance from theve hicle in
front, forve hicle speed, for braking in good time
and for st aying in lane.
% In wintry road conditions, the maximum e.ect
of 4MATIC can be achie ved only if you use

TE Accelerated ageing of the high-volt-

result of its basic characteristics, the

av ailable from the high-voltage battery
decrease 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-

The following factors could accelerate the age-
ing of the high-voltage batter y:
R a high le vel of charge , especially if the

R frequent rapid charging with direct cur rent
(mode 4)

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

ep the high-voltage battery continuously
connected topowe r supply equipment.
R If leaving theve hicle idle for lengt hyperiods of

tures.
R Check the high-voltage battery's charge level
ev ery six weeks (/ page 214).
R Char gethe high-voltage battery if thech arge
