Mercedes-Benz recommends that you acti-
vate COLLISION PREVENTION ASSIST as a
visual and acoustic aid.
The vehicle uses the sensors of COLLISION
PREVENTION ASSIST during radar-based
AUTO
recuperation (D ). The sensors detect the
distance to the vehicle ahead and its speed.
The intensity of recuperation is then auto-
matically adjusted to the current traffic sit-
uation.
The range can then be increased by storing
energy efficiently. Adjustment is infinitely var-
iable from overrun mode (no recuperation) to
maximum recuperation.
Examples of radar-based recuperation:
Approaching a slower vehicle, a decelerat-
R
ing vehicle or when following a vehicle
downhill. Your vehicle decelerates slightly
and increases recuperation.
Driving when no vehicle is detected in front
R
or when a vehicle is detected in the far dis-
tance or an accelerating vehicle is detec-
ted. Your vehicle switches to overrun mode
at higher speeds.
Driving on a steep downhill slope. Acceler-
R
ation downhill is reduced and recuperation
is increased. This is comparable with shift-
ing down when driving downhill.
To activate radar-based recuperation:
X
pull one steering wheel paddle shifter :
or ; towards you and hold for
about one second.
To deactivate radar-based recupera-
X
tion: briefly pull one steering wheel paddle
shifter : or ; towards you.
If you change between radar-based and man-
ual recuperation, the following levels are acti-
vated depending on the steering wheel pad-

In particular, the function of the radar sensors

there is dirt on the sensors or anything else

covering the sensors
there is snow or heavy rain

there is interference by other radar sources

there are strong radar reflections, for

Following damage to the front end of the vehi-
cle, have the configuration and operation of
the radar sensor checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at slow speeds where there is no visible
damage to the front of the vehicle.
i If the radar sensor is not available, the
system switches automatically to level D
with moderate recuperation. In this case
have the radar sensor checked at a quali-
fied specialist workshop.
Automatic adjustment of recuperation

Automatic adjustment of recuperation on
downhill gradients is available in level
