2016 MERCEDES-BENZ B-Class ELECTRIC heating

The high-voltage battery can be charged as
follows:
Rthrough energy recuperation while the
vehicle is in motion
Rwith the charging cable at a mains socket
while the vehicle is stationary
Rwith the charging cable at a charging sta-
tion while the vehicle is stationary
The high-voltage battery can be charged
using a single-phase charging cable in a volt-
age range from 100 V to 240 V.
If the condition of charge drops to less than
13%, the high-voltage battery reserve indica-
tor lamp lights up in the instrument cluster.
Charge the high-voltage battery as soon as
possible.
Below a condition of charge of 5%, the per-
formance of the vehicle is reduced. The vehi-
cle'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
significantly reduced at very low outside tem-
peratures. The high-voltage battery is then no longer able to provide the normal electrical
power output.
High outside temperatures
To prevent damage to the high-voltage bat-
tery due to very high outside temperatures,
the maximum power output of the high-volt-
age battery is reduced automatically.
The E-CELL display indicates the maximum
amount of power available (
Ypage 183).
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 sup-
ply.
Temperatures below
Ò13‡(Ò25 †) and over
104 ‡ (40 †), which affect the vehicle for a
period of more than seven days, can cause
irreversible 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 level too low. Stop and
charge immediatelymessage. This pro-
tects the battery from exhaustive discharge.
It is not possible to restart the drive system
until after charging.
Do not leave the vehicle parked for longer
than 14 days with a high-voltage battery con- dition of charge below 20%.
You can check the condition of charge in the
charge level display (
Ypage 184).
Further information on the "Energy flow dis-
play" can be found in the "Trip" menu
(
Ypage 187).
Energy consumption and range
This range is reduced by:
Rhigh and low outside temperatures
Ra non-anticipatory driving style
Rswitching on consumers, e.g. air-condition-
ing system or heating.
The battery's physical characteristics are
such that leaving the vehicle parked for an
extended period at low outdoor temperatures
without charging it can lead to:
Ra reduction in battery performance
Rlonger charge times
In extreme cases, this could mean that the
vehicle cannot be started. For this reason,
connect the charging cable when leaving the
vehicle parked for long periods at low outdoor
temperatures.

If you use the supplied 12 A charging cable to
charge a high-voltage battery:
Rthe charge time increases considerably
Relectrical consumption increases consider-
ably
Where possible, charge the high-voltage bat-
tery at a charging station (
Ypage 149). Only
then can certified electrical energy consump-
tion levels be reached.
iThe charging process can vary depending
on the charging station. Therefore, always
observe the local information.
Stowing the charging cable
The charging cable can be stowed in a bag in
the trunk of the vehicle. To do so, the bag
must be secured to the cargo tie-down rings
using the retaining strap provided.

Setting the maximum charge current
GWARNING
If the charge current draw via a mains socket
is too high during the charging process, the
external electrical system may overheat.
There is a risk of fire.
Before beginning the charging process, check
the maximum permissible charge current
locally. Consult a qualified expert to do so
where necessary.
If necessary, adjust your vehicle's settings.
!An excessive charge current can blow a
fuse or lead to overheating of the external
power supply. Check whether the external
power supply is compatible with the set

Calling up functions in the "My
Mercedes Electric - Vehicle Homepage"
The "My Mercedes Electric - Vehicle Home-
page" allows you access to information about
your vehicle and its functions using remote
query and remote configuration. For example,
climate control can be activated using remote
configuration which means that it need not be
set in the vehicle. Power for the climate con-
trol is primarily supplied via the charging
cable connected to the mains supply. In this
way, the range of the vehicle in most cases is
not reduced. If climate control is activated,
the battery charge level and thus the range
may be reduced. The "Vehicle Homepage"
provides you with information all about how
to use your vehicle.
If the vehicle is entered in your personal area
of the "Vehicle Homepage", you can also
access the following functions:
Rrequest the current condition of charge of
the high-voltage battery
Rprogram the departure time (Ypage 195)
Rorder and activate the "Pre-entry climate
control at departure time" function
If the vehicle is charging, the predicted charg-
ing time and the predicted range will also be
shown.
This data is estimated and may be influenced
by the following factors:
Routside temperature
Rswitched on consumers, e.g. climate con-
trol and seat heating
Rpersonal driving style
Rroad and traffic conditions
Rroute characteristics
Therefore, allow for a sufficient reserve.
iInformation on additional functions and
operating instructions can be found on the "Vehicle Homepage".
Connecting the vehicle to the Internet
Via a radio module
This function is not available in all countries
and requires an activated mbrace access.
You can use the "Vehicle Homepage" if the
vehicle has a connection to the Internet via a
mobile phone. The radio module uses a
mobile phone connection and transmits the
necessary data by radio. The vehicle auto-
matically recognizes whether a connection to
the Internet via the radio module is possible
or not. No presets are necessary.
To enable the transfer of data via the mobile
communications module, you do not need a
SIM card.
iRestrictions in reception are possible if
the vehicle is in an underground car park,
for example. Restrictions may also occur in areas with poor mobile network coverage.
Parking
Important safety notes
GWARNING
If you release the parking brake on uphill or
downhill gradients, the vehicle can begin to
move when in park position P. There is a risk
of an accident.
To avoid hazardous situations:
Rprevent the parked vehicle from rolling on
uphill or downhill gradients by always
applying the parking brake.
Rdo not park the vehicle on uphill or downhill
gradients if the parking brake is malfunc-
tioning.

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.:
Rload
RTire pressure
Rcold start
Rchoice of route
Relectrical 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:
RAcceleration(evaluation of all accelera-
tion processes):
-The bar fills up: moderate acceleration,
especially at higher speeds
-The bar empties: sporty acceleration
RConstant(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
RCoasting(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
and 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
will
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.
For further information on the ECO display,
see (
Ypage 187).
Braking
Important safety notes
GWARNING
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:
Rwhen the condition of charge of the high-
voltage battery increases
Rif the high-voltage battery is not yet at a
normal operating temperature
Rwhen driving close to the maximum speed
Rwhen the vehicle is almost stationary
Rin transmission position N
Rduring 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.

Driving systems
Cruise Control
General notes
Cruise control maintainsaconstant road
speed for you. It brakes automatically in order to avoid exceeding the set speed. Change into
transmission position D
-(Ypage 138) on long
and steep downhill gradients. This increases
recuperation in overrun mode. This relieves
th e load on the brake system and prevents
th ebrake s from overheating and wearing too
quickly.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed foraprolonged period. You can
store any road speed above 20 mph
(30 km/ h).
The speed indicated in the speedometer may
differ slightly from the speed stored.
Important safety notes
If you fail to adapt your driving style, cruise
control can neither reduce the risk of an acci-
dent nor override the laws of physics. Cruise
control cannot take into account the road,
traffic and weather conditions. Cruise control
is only an aid. You are responsible for the dis-
tance to the vehicle in front, for vehicle speed,
for braking in good time and for staying in
your lane.
Do not use cruise control:
Rin road and traffic conditions which do not
allow you to maintain a constant speed e.g.
in heavy traffic or on winding roads
Ron slippery road surfaces. Braking or accel- erating could cause the drive wheels to lose
traction and the vehicle could then skid
Rwhen there is poor visibility, e.g. due to fog,
heavy rain or snow
If there is a change of drivers, advise the new
driver of the speed stored.

Rsolvents
Rcleaning agents containing solvents
Do not scrub.
Do not touch the surfaces or protective
films with hard objects, e.g. a ring or ice
scraper. You could otherwise scratch or
damage the surfaces and protective film.
!Do not park the vehicle for an extended
period straight after cleaning it, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after clean-
ing. Braking heats the brake discs and the
brake pads/linings, thus drying them. The
vehicle can then be parked.
Regular care of your vehicle is a condition for
retaining the quality in the long term.
Use care products and cleaning agents rec-
ommended and approved by Mercedes-Benz.
Washing the vehicle and cleaning the
paintwork
Automatic car wash
GWARNING
Braking efficiency is reduced after washing
the vehicle. There is a risk of an accident.
After the vehicle has been washed, brake
carefully while paying attention to the traffic
conditions until full braking power is restored.
!If the HOLD function is activated, the vehi-
cle brakes automatically in certain situa-
tions.
To prevent damage to the vehicle, deacti-
vate the HOLD function in the following or
other similar situations:
Rwhen towing the vehicle
Rin the car wash
!Never clean your vehicle in a Touchless
Automatic Car Wash as these use special cleaning agents. These cleaning agents can
damage the paintwork or plastic parts.
!When washing your vehicle in a tow-
through car wash, make sure that the selec- tor lever is in position N, otherwise the
vehicle could be damaged.
!Make sure that:
Rthe side windows are fully closed.
Rthe ventilation/heating is switched off
(the OFF button has been pressed/the
airflow control is set to position 0).
Rthe windshield wiper switch is at position
0.
The vehicle may otherwise be damaged.
You can wash the vehicle in an automatic car
wash from the very start.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
After using an automatic car wash, wipe off
wax from the windshield and the wiper
blades. This will prevent smears and reduce
wiping noises caused by residue on the wind-
shield.
Washing by hand
In some countries, washing by hand is only
allowed at specially equipped washing bays.
Observe the legal requirements in each coun- try.
