Operation Manual

D
-
Sporty driving or driving on a
downhill gradient
The brake pedal does not need
to be used as often because the
extent of the deceleration is
greater than in D.
Energy use when decelerating is
considerably higher than when
the vehicle is braked with the
brake pedal.
D
AUTO
(radar-
based)
The intensity of recuperation is
automatically adjusted to the
current traffic situation.
Default setting
In levels D and D
-
, deceleration can be con-
trolled in an infinitely variable manner using
the accelerator pedal.
The braking performance of the electric
motor using recuperative braking is, in some
operating modes, either reduced or not effec-
tive:
R
when the condition of charge of the high-
voltage battery increases
R
if the high-voltage battery is not yet at a
normal operating temperature
R
when driving close to the maximum speed
R
when the vehicle is almost stationary
R
in transmission position N
R
during and after ESP stability control
If you do not make an additional effort to
apply the brake yourself, the braking effect
may not be sufficient. If necessary, counter-
act the reduced regenerative braking effect
by applying the brake yourself.
Radar-based recuperation
The vehicle uses the sensors of COLLISION
PREVENTION ASSIST PLUS during radar-
based recuperation (D
AUTO
). The sensors
detect the distance to the vehicle ahead and
its speed. The intensity of recuperation is
then automatically adjusted to the current
traffic situation.
The range can then be increased by storing
energy efficiently. Adjustment is infinitely var-
iable from overrun mode (no recuperation) to
maximum recuperation.
Maintain sufficient distance to the vehicle in
front. Mercedes-Benz recommends that you
activate COLLISION PREVENTION ASSIST
PLUS as a visual and acoustic aid.
Examples of radar-based recuperation:
R
Approaching a slower vehicle, a decelerat-
ing vehicle or when following a vehicle
downhill. Your vehicle decelerates slightly
and increases recuperation.
R
Driving when no vehicle is detected in front
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.
R
Driving on a steep downhill slope. Acceler-
ation downhill is reduced and recuperation
is increased. This is comparable with shift-
ing down when driving downhill.
X
To activate radar-based recuperation:
pull steering wheel paddle shifter : or ;
towards you and hold for about one second.
X
To deactivate radar-based recupera-
tion: briefly pull 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 selection via the
steering wheel paddle shifters:
