2015 MERCEDES-BENZ B-Class ELECTRIC sport mode

Drive program
Sis characterized by the fol-
lowing:
R the vehicle exhibits sporty driving charac-
teristics.
R the entire power output can be utilized by
depressing the accelerator pedal.
Drive program E+is characterized by the fol-
lowing:
R reduced torque and significantly reduced
power. This supports an especially efficient
and even driving style and results in a
reduction in speed to approximately
70 mph (110 km/h).
R the vehicle pulling away more gently in
forward gear unless the accelerator pedal
is depressed fully.
R the wheels are less likely to spin.
R particularly efficient overrun.
R full power output by using kickdown.
R the performance of air-conditioning system
and heating are reduced. Steering wheel paddle shifters

You can increase or reduce recuperation in
overrun mode using the steering wheel pad-
dle shifters. When you remove your foot from
the accelerator pedal, recuperation occurs.
The electric motor is then used as a alternator and energy is recovered while driving. The
recuperated electrical energy is stored in the
high-voltage battery. A higher energy recu-
peration level means that the vehicle is
braked more powerfully.
If necessary, counteract the reduced regen-
erative braking effect by applying the brake
yourself.
Information on the Recuperative Braking Sys-
tem (Y page 68).
X To decrease recuperation: pull right-hand
steering wheel paddle shifter ;.
X To increase recuperation: pull left-hand
steering wheel paddle shifter :.
The various recuperation levels are shown in
the transmission position display once Dhas
been selected (Y page 134).
The following recuperation levels are availa-
ble in overrun mode:
R no recuperation (D +
, coasting mode)
R moderate recuperation (D)
R high recuperation (D -
)
R recuperation depending on the traffic sit-
uation (D AUTO
, radar-based)
You can see the intensity of recuperation in
overrun mode by reading the recuperation
performance value shown in the power dis-
play (Y page 183).
Every time drive position Dis selected, the
transmission switches into recuperation level
D AUTO
automatically.
The various different levels are to be used
under the following conditions: D
+ Driving without much braking
and without the presence of
obstacles or sharp bends
The vehicle retains the maxi-
mum possible amount of kinetic
energy. D

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

(radar-
based) The intensity of recuperation is
automatically adjusted to the
current traffic situation.

Dand 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: ;

The ECO display does not indicate the actual
fuel consumption. A fixed percentage count
in the ECO display does not indicate a fixed
consumption.
Apart from driving style, consumption is
dependent on many factors such as, e.g.:
R load
R tire pressure
R cold start
R choice of route
R electrical consumers switched on
These factors are not included in the ECO dis-
play.
The evaluation of your driving style is carried
out using the following three categories:
R Acceleration
Acceleration (evaluation of all accelera-
tion processes):
- The bar fills up: moderate acceleration,
especially at higher speeds
- The bar empties: sporty acceleration
R Constant
Constant (assessment of driving behavior
at all times)
- The bar fills up: constant speed and
avoidance of unnecessary acceleration
and deceleration
- The bar empties: fluctuations in speed
R Coasting
Coasting (assessment of all deceleration
processes)
- The bar fills up: anticipatory driving,
keeping your distance and early release
of the accelerator. The vehicle can coast
without use of the brakes.
- The bar empties: frequent braking
To achieve a higher value in the categories
Acceleration Acceleration andConstant
Constant, drive the vehi-
cle in drive program E+orE.
On long journeys at a constant speed, e.g. on
the highway, only the bar for Constant
Constantwill
change.
The ECO display summarizes the driving char- acteristics from the start of the journey to its completion. For this reason, the bars change
dynamically at the beginning of the journey.
On longer journeys, there are fewer changes. For more dynamic changes, carry out a man-
ual reset.

see (Y page 187). Braking
Important safety notes G
WARNING
If you increase the recuperation level on slip- pery road surfaces, the drive wheels may lose
their traction. There is an increased danger of skidding and accidents.
Do not increase the recuperation level on slip-
pery road surfaces.
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.
Downhill gradients On long, steep gradients, you must reduce the
load on the brakes by selecting maximum
recuperation. This helps you to avoid over-
heating the brakes and wearing them out
excessively.
Recuperation allows the vehicle to be decel-
erated without placing a load on the braking
system. 158

Useful information
i This Operator's Manual describes all
models and all standard and optional equip- ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.

ist workshops (Y page 25). Loading guidelines
G
WARNING
If objects, luggage or loads are not secured or not secured sufficiently, they could slip, tip
over or be flung around and thereby hit vehicle
occupants. There is a risk of injury, particu-
larly in the event of sudden braking or a sud-
den change in direction.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey.
The handling characteristics of a laden vehi-
cle are dependent on the distribution of the
load within the vehicle. For this reason, you
should observe the following notes when
transporting a load:
R Never exceed the maximum permissible
gross vehicle mass or the gross axle weight rating for the vehicle (including occupants).
The values are specified on the vehicle
identification plate on the B-pillar of the
driver's door.
R The cargo compartment is the preferred
place to carry objects.
R Position heavy loads as far forwards as pos-
sible and as low down in the cargo com-
partment as possible. R
The load must not protrude above the
upper edge of the seat backrests.
R Always place the load against the rear or
front seat backrests. Make sure that the
seat backrests are securely locked into
place.
R Always place the load behind unoccupied
seats if possible.
R Use the cargo tie-down rings and the parcel
nets to transport loads and luggage.
R Use cargo tie-down rings and fastening
materials appropriate for the weight and
size of the load.
R Hook in the cargo net when loading.
R The maximum load capacity of the stowage
well under the cargo compartment floor is
55 lbs (25 kg).
R Secure the load with sufficiently strong and
wear-resistant tie-downs. Pad sharp edges
for protection.
! Do not position the load on one part of the
folding cargo compartment floor only. The
maximum load capacity of the folding cargo
compartment floor is 220 lbs (100 kg). Dis-
tribute the weight evenly to avoid damaging
the cargo compartment floor. Place a solid board under the load if necessary. Please
note that the load on the cargo compart-
ment floor will be increased when the load
is lashed down. Stowage areas
