2017 MERCEDES-BENZ B-Class sport mode

E+ Economy Plus
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 reduc-
tion 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 over- run mode using the steering wheel paddle shift-
ers. When you remove your foot from the accel-
erator pedal, recuperation occurs. The electric
motor is then used as a alternator and energy is recovered while driving. The recuperated elec-
trical energy is stored in the high-voltage bat-
tery. A higher energy recuperation level means
that the vehicle is braked more powerfully.
If necessary, counteract the reduced regenera-
tive braking effect by applying the brake your-
self.

tem (Y page 64). X
To decrease recuperation: pull right-hand

X To increase recuperation: pull left-hand

The various recuperation levels are shown in the
transmission position display once Dhas been
selected (Y page 112).
The following recuperation levels are available in
overrun mode:
R no recuperation (D +
, coasting mode)
R moderate recuperation ( D)
R high recuperation ( D-
)
R recuperation depending on the traffic situa-
tion (D AUTO
, radar-based)
You can see the intensity of recuperation in
overrun mode by reading the recuperation per-
formance value shown in the power display
(Y page 153).
Every time drive position Dis selected, the
transmission switches into recuperation level

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 maximum
possible amount of kinetic
energy. D
Normal driving
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 cur-
rent traffic situation.

Influences on the charging behavior
and the charge state of the high-volt-
age battery
Terms of use Observe the following notes:
R information on exceptions and limitations in
warranty documentation and in the related
Maintenance Booklet
R maintenance notes for the high-voltage bat-
tery in the Maintenance Booklet
Method of operation The vehicle is equipped with a high-voltage bat-
tery for driving. The high-voltage battery stores
the energy needed to operate the electric motor and releases it again.
The electric motor uses energy that has been
stored in the high-voltage battery when pulling
away, accelerating and during the journey.
In overrun mode (except D+), kinetic energy is
converted by means of energy recuperation into
electrical energy and stored in the high-voltage
battery.
The high-voltage battery can be charged as fol-
lows:
R through energy recuperation while the vehicle
is in motion
R with the charging cable at a mains socket
while the vehicle is stationary
R with the charging cable at a charging station
while the vehicle is stationary
The high-voltage battery can be charged using a
single-phase charging cable in a voltage range
from 100 V to 240 V.
If the condition of charge drops to less than 13%, the high-voltage battery reserve indicator lamp
lights up in the instrument cluster. Charge the
high-voltage battery as soon as possible.
Below a condition of charge of 5%, the perform-
ance of the vehicle is reduced. The vehicle's
high-voltage electrical system switches off at a
condition of charge of 0%.
Use of the pre-entry climate control function
may mean that the high-voltage battery is not
fully charged. High and low outside temperatures Low outside temperatures
The efficiency of the high-voltage battery is sig-
nificantly reduced at very low outside tempera-
tures. The high-voltage battery is then no longer able to provide the normal electrical power out-
put.
High outside temperatures
To prevent damage to the high-voltage battery
due to very high outside temperatures, the max- imum power output of the high-voltage battery
is reduced automatically.
The E-CELL display indicates the maximum
amount of power available (Y page 152).
Notes on battery care Avoid storing or transporting the vehicle in high
temperatures over a long period (e.g. container
transport).
If you park the vehicle and leave it stationary for
longer periods, connect it to a power supply.
Temperatures below 00F813 ‡ (00F825 †) and over
104 ‡ (40 †), which affect the vehicle for a
period of more than seven days, can cause irre- versible damage.
Discharged battery The vehicle's high-voltage electrical system
switches off if the high-voltage battery is com-
pletely discharged. 30 seconds prior to this, you
are informed of the switch-off by the Battery

You can check the condition of charge in the

Drive sensibly – save energy
Observe the following tips to save energy:
R The tires should always be inflated to the rec-
ommended tire pressure.
R Remove unnecessary loads.
R Remove roof racks when they are not needed.
R Avoid frequent acceleration or braking.
Energy consumption also increases when driv-
ing in low or high outside temperatures, in stop-
start traffic, on short journeys and in hilly ter-
rain.
Drinking and driving G
WARNING
Drinking and driving and/or taking drugs and driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of a serious or even fatal acci-
dent is greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-
ing drugs. ECO display
The ECO display shows you how economical
your driving style is. The ECO display assists you in achieving the most economical driving style
for the selected settings and prevailing condi-
tions. Your driving style can significantly influ-
ence the vehicle's consumption. 0043

Coasting
(evaluation of all decelera-
tion processes):
R the outer area fills up and the inner
area lights up green: anticipatory
driving, keeping your distance and
early release of the accelerator.
The vehicle can coast without use
of the brakes.
R the outer area empties and the
inner area is gray: frequent heavy

Constant
(continuous evaluation
over the entire journey):
R the outer area fills up and the inner
area lights up green: constant
speed and avoidance of unneces-
sary acceleration and deceleration
R the outer area empties and the
inner area is gray: fluctuations in
speed The three inner areas display the current driving
style and light up green as a result of a particu-
larly economical driving style. Depending on the driving situation, up to two areas may light up
simultaneously.
At the beginning of the journey, the three outer
areas are empty and fill up as a result of eco-
nomical driving. A higher level indicates a more
economical driving style. If the three outer areas 132

rking

Observe the legally required minimum tire tread
depth (Y page 258). Winter tires can reduce the
braking distance on snow-covered surfaces in
comparison with summer tires. The braking dis-
tance is still much further than on surfaces that
are not icy or covered with snow. Take appro-
priate care when driving.
Further information on winter tires (M+S tires)
(Y page 259).
Temperature G
WARNING
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla-
tion, or excessive loading, either separately or
in combination, can cause excessive heat
build-up and possible tire failure.
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel. Sus- tained high temperature can cause the material
of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire
failure. The grade C corresponds to a level of
performance which all passenger car tires must
meet under the Federal Motor Vehicle Safety
Standard No. 109. Grades B and A represent
higher levels of performance on the laboratory
test wheel than the minimum required by law. Tire labeling
