WARNING
The operating condition of the high-volt-
age battery (e.g. not yet at normal operat-
ing temperature or fully charged) influen-
ces the braking effect of the electric
motor.
In overrun or braking mode, the motor's
braking effect may therefore be reduced or
may not be present at all.
As a result of the reduced engine braking
effect, you may cause an accident and
injure yourself or others.
Compensate for the reduced engine braking
effect by pressing the brake pedal accord-
ingly, as required. !
Do not hang any objects on the power
gauge.
This could cause the power gauge to be
torn from its mountings and be damaged.
Power gauge 0044contains two segments:
R Section right of 0
Power gauge 0044indicates the current
power that the drive system delivers to
the rear wheels. 100 % correspond to
55 kW peak power.
R Section left of 0
When you release the accelerator pedal
or when you depress the brake pedal, the
electric motor operates as a generator.
Electric current is produced and stored
in the high-voltage battery. As long as
the high-voltage battery is being
charged, the electric motor simulates an
engine brake.
When the pointer of power gauge 0044is in
the "OFF“ position, the vehicle is not ready

WARNING
Follow the recommended settings for heat-
ing and cooling given on the following pages. Otherwise the windows could fog up,
impairing visibility and endangering you
and others.
The air conditioning improves the level of
comfort when driving at high outside tem-
peratures by cooling and dehumidifying
the air.
Nearly all dust particles, pollutants, are
filtered out by an integrated particle fil-
ter before outside air enters the passenger
compartment through the air distribution
system. It also operates when the air con-
ditioning is switched off and you have
switched on the blower.
The dehumidification of the air by the air
conditioner prevents the windows from
misting up when the outside air humidity
is high.
This effect can also be used to defrost the
windows. For this, make sure, in addition
to the air conditioner, that the heater is
on the maximum setting.
The air conditioner only works when:
R the ignition is switched on
R the blower is switched on
R the driver's door is closed
Maximum effectiveness is achieved if you
drive with the windows closed.
If the operating temperature of the
high‑voltage battery is too high, the
high‑voltage battery is cooled by the air
conditioner. When the air conditioner
switches on, the cooling output in the vehi-
cle's interior is reduced as a result. The
temperature in the vehicle's interior may
rise briefly.
If the air conditioner is not switched on,
the compressor of the air conditioner and
the vehicle's cooling fan are switched on
automatically. This cools the high‑voltage
battery but not the vehicle's interior. When
the high‑voltage battery reaches the nom-
inal temperature again, the air condi-
tioner switches off automatically. Air conditioning with climate control

G
WARNING
When operating the heating or air condi-
tioning with climate control, the air that
enters the passenger compartment through
the air vents can be very hot or very cold
(depending on the set temperature). This
may cause burns or frostbite on unprotected
skin in the immediate area of the air vents.
Always keep sufficient distance between
unprotected parts of the body and the air
vents. If necessary, use the air distribu-
tion control to direct the air to air vents
in the vehicle interior that are not in the
immediate area of unprotected skin.
To make sure the heating or air condition-
ing with climate control works properly,
please observe the following:
R Keep the air intake grill free from
deposits, e.g. ice or snow, to ensure that Air conditioning with climate control
101>> Controls. Z
Use only charging cables which have been
approved and recommended for the vehicle.
Do not use:
R extension chords
R cable reels
R multiple sockets
R travel adapters
i When possible, only charge the high-
voltage battery when the charge level is
below 80 %.
It is recommended to charge the high-
voltage battery prior to reaching less
than 20% state of charge.
Discharged high-voltage battery When the high-voltage battery is com-
pletely discharged, the drive system is
switched off. This protects the battery
from exhaustive discharge.
i By switching the ignition off and on
again, the drive system can be briefly
reactivated once. This allows you to park
the vehicle safely.
Do not allow your vehicle to remain sta-
tionary for more than 14 days with a dis-
charged, or nearly discharged, high-volt-
age battery. You can check the charge level
with the charge level gauge (Y page 81).
High or low outside temperatures The efficiency of the high-voltage battery
is temperature-dependent and decreases
at high or low temperatures. Additionally,
the electrolytes used can gel at very low
temperatures.
You can check the maximum capacity avail-
able using the indicator in the multifunc-
tion display (Y page 87). Energy consumption and range The available energy of the high-voltage
battery is reduced by:
R
low outside temperatures
R switching on electrical consumers
At low temperatures and after being parked
for an extended period without charging,
the physical properties of the high-volt-
age battery:
R can cause a significant reduction in the
performance of the battery
R can lead to longer charging times
In extreme cases, you will not be able to
start the vehicle. For this reason, always
connect the charging cable or make sure the
battery is completely charged when park-
ing the vehicle in low outside tempera-
tures or for an extended period of time.
Due to its physical properties, the capa-
city of a high-voltage battery decreases
over its lifespan.
Thus, the following are reduced:
R the maximum attainable range of the
vehicle
R the maximum performance output (accel-
eration) of the vehicle
You can actively contribute to the reduc-
tion of the vehicle's energy consumption
by:
R driving conservatively
R maintaining the vehicle regularly
R decreasing the use of electrical consum-
ers
Notes on battery care Avoid storing and transporting the vehicle
at high temperatures for extended periods
of time (e. g. container transport).
When out of use for longer periods of time,
connect the vehicle to a voltage supply.
If the vehicle is not connected to a voltage
supply, it must remain within a tempera- High-voltage battery

i You can also set the maximum charge
current via the control system
(Y page 92).
If differing values are set on the charg-
ing cable and the control system, the
high‑voltage battery is charged using
the lowest value.

The payment procedure and charging proc-
esses may differ between public charging
stations, depending on the provider.
Please make yourself familiar with the
proper procedures of the public charging
station at which you are intending to
charge your vehicle.
Charging station without charging com-
munication You must activate charging stations with-
out charging communication before the
charging process. This can be done with an
RFID card or a telephone call, for example. High-voltage battery
117>> Operation. Z
Observe the provider's instructions at the
charging station.
Charging station with charging commu-
nication („Plug&Charge“) You do not have to activate charging sta-
tions with charging communication before
the charging process. This is done by the
vehicle. This function is called "Plug &
Charge". Information is exchanged
between the vehicle and the charging sta-
tion via the charging cable for activation.
This is for:
R mutual authorization of the vehicle and
the charging station
R verification of contract data
R automatic billing of the energy costs
Electronic certificates are used here for
secure exchange of data.
If the verification of contract data is suc-
cessful, the charging process is initiated.
i A preliminary version of the
ISO/IEC 15118 standard is used for com-
munication between the vehicle and the
charging station. If it is necessary to
update your vehicle, consult an author-
ized electric drive smart center.
In order to use "Plug & Charge", you have to
configure the functions of your vehicle on
the "Vehicle Homepage" (Y page 120). For
this you require a "Plug & Charge" certif-
icate which you receive from your power
company after concluding a suitable con-
tract. Consult an authorized electric drive
smart center if you have problems with the
configuration or have no access to the
Internet.
The charging station offers information on
the availability of electricity and costs.
This information is processed by the vehi-
cle and is used for an optimum charging of
the high‑voltage battery (Y page 123). The
energy costs are automatically calculated
after the charging process is complete. With your existing electricity contract,
you and others who have access to your vehi-
cle can charge the costs to your electricity
bill. For this reason, cancel your existing
electricity contract for this vehicle
before you sell it. Delete your "Plug &
Charge" certificate by all means.
i
You can delete the certificate from the
vehicle's data on the "Vehicle Home-
page". Please consult an authorized
electric drive smart center if you do not
have access to the Internet.
If the charging station allows the con-
nected vehicle access to the Internet, you
can call up and change information per-
taining to the vehicle on the "Vehicle
Homepage" (Y page 120).
