2015 MERCEDES-BENZ B-Class ELECTRIC charging

Outside temperature display
You should pay special attention to road con-
ditions when temperatures are around freez-
ing point.
Bear in mind that the outside temperature
display indicates the temperature measured
and does not record the road temperature.
The outside temperature display is in the mul- tifunction display (Y page 186).
Changes in the outside temperature are dis-
played after a short delay. E-CELL display

WARNING
There is a risk of an accident if you accelerate or overtake when the power output of the
drive system is reduced.
You should therefore adapt your driving style
and drive particularly carefully. Charge the
high-voltage battery at a charge station imme- diately. X
Start the drive system (Y page 133).
E-CELL display :shows the available
power of the drive system.
Under normal operating conditions, E-CELL
display :is in the maximum range.
The power output available may deviate from
the maximum range in the event of:
R very high or low outside temperatures
R very high performance requirements for a
longer period of time R
very low condition of charge of the high-
voltage battery
R a malfunction in the drive system
The reduced power output can be improved
by charging the high-voltage battery
(Y page 140). Power display
Power display
:contains two areas:
R Area above 0
Here, the current amount of power that the
drive system is feeding to the wheels is dis-
played.
R Area below 0
Here, the vehicle's recuperative power in
overrun mode is displayed.
If the needle for the power display is in the
OFF position, the vehicle is not ready to drive
because:
R the drive system has not yet started
R the charging cable is still connected to the
vehicle socket
R there is insufficient power available from
the high-voltage battery
R the vehicle's high-voltage electrical system
is malfunctioning
When the drive system is started, the needle
in the power display moves to position 0. The
display Ready
Ready appears in the lower multifunc-
tion display. The vehicle is ready to drive.
The boost area for maximum acceleration can
be reached using kickdown (Y page 137). Displays and operation
183On-board computer and displays Z

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 necessary, counteract the reduced regen-
erative braking effect by applying the brake
yourself. Charge level display
Condition of charge display

condition of charge of the high-voltage bat-
tery.
The charge value is shown as a percentage in
the Energy Flow Energy Flow menu in the instrument
cluster (Y page 187).

Energy Flow menu can also be dis-
played in the COMAND/Audio display.
The condition of charge of the high-voltage
battery has dropped into the reserve range if
the drive system is running and:

Levelmes-
sage appears in the display
R the indicator lamp in the instrument cluster
lights up Charge the high-voltage battery from a con-
dition of charge of less than 20% at:
R an electrical outlet
R a charging station
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 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. Operating the on-board computer

Displaying the range and current con-
sumption X
Press the =or; button on the steer-
ing wheel to select the Trip Tripmenu.
X Press the 9or: button to select
approximate range and current fuel con-
sumption.
The approximate range depends on the con-
dition of charge of the high-voltage battery
and your current driving style. If the high-volt- age battery condition of charge is low, the
display shows a vehicle being charged
instead of the approximate range.
The specified values for range depend on the
driving program selected and may vary as a
result of:
R higher and lower outside temperatures
R the style of driving
R activated electrical consumers 188
