Depending on the selected recuperation le vel,the
electric mo tors are operated as an alternator
when in overrun mode and during braking in order
to charge 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. Also
brake with the service brake if necessar y.Alw ays

ARNI NGRisk of accident if ECO Assist
does not pr ovide su1cient deceleration
ECO Assist only brakes your vehicle when you
ta ke your foot o. thega s pedal. If vehicles are
de tected late, e.g. aTer tight cur ves, or if you
do not react immediately tothe ECO Assist
displa y,the deceleration may not be su1cient. #
React prom ptly to the ECO Assist recom-
mendation and take your foot o. thegas
pedal. #
Adjust your speed tothe driving condi-
tions and maintain a suitable distance
from theve hicle in front. #
Brake theve hicle yourself and/or take
ev asive action. ECO Assist is active only in
hÃ
(/ page 185).
Depending on theve hicle's equipment, ECO
Assist anal yses data forth eve hicle's expected
ro ute. This allo ws the system tooptimally adjust
th e driving style forth ero ute ahead, use minimal
energy and recuperate as much as possible. If the
system has de tected an event ahead or a vehicle in front and
theve hicle is approaching theev ent,
ECO Assist calculates the optimised speed pro/le
based on the distance, speed and available route
information.
If yo ure lease the accelerator pedal in this case,
intelligent recuperation starts in overrun mode. If
ECO Assist has de tected a vehicle tr avelling in
front or a stationary vehicle ahead, it can brake
yo ur vehicle toa standstill. This may be the case,
fo rex ample, at the end of a tra1c jam or if the
de tected vehicle ahead stops in front of you.
If th e deceleration pr ovided byECO Assist is not
su1cient, you must also brake with the service
brake.
At low speeds, e.g. in a multi-stor eycar park or on
play st reets, no adjustment is made for stationary
ve hicles and therefore there is no displa y. 1
