When the hill‑start assist system stops
braking the vehicle, it can roll
backwards.
If you open the driver’s door, the
hill‑start assist system is deactivated
and a warning signal sounds.
Your vehicle has a hill‑start assist system.
On uphill grades the hill‑start assist
system maintains the pressure in the brake
system for approximately one second after
you have released the brake pedal.
Therefore, you can start off smoothly
without the vehicle moving immediately
after releasing the brake pedal.
X Release the brake pedal.
X Apply sufficient pressure to the
accelerator pedal to drive off.
On uphill grades with higher inclination,
the hill-start assist system will release
the pressure in the brake system after
approximately two seconds. A warning
signal sounds and the transmission
position indicator shows a flashing N in
order to warn you of the vehicle rolling
backwards.

WARNING
Follow the recommended settings for
heating and cooling given on the following
pages .Otherwise the windows could fog up,
impairing visibility and endangering you
and others.
The air conditionin gimproves the leve lof
comfort when driving at high outside
temperatures by cooling and
dehumidifying the air.
Nearly all dust particles, pollutants, are
filtered out by an integrated particle
filter before outside air enters the
passenger compartment through the air
distribution system .It also operates when
the air conditioning 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
vehicle'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,

WARNING
When operating the heating or air
conditioning with climat econtrol, 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 distribution control to direct the air
to air vents in the vehicle interior that are
not in the immediate area of unprotected

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
completely 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
reactivate donce. This allows you to park
the vehicle safely.
Do not allow your vehicle to remain
stationary for more than 14 days with a
discharged, or nearly discharged,
high‑voltage battery. You can check the
charge level with the charge level gauge
(Y page 79).
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
available using the indicator in the
multifunction display (Y page 83).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‑voltage battery:
R can cause a significant reductio ninthe
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
parking the vehicle in low outside
temperatures or for an extended period of
time.
Due to its physical properties, the
capacity 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
(acceleration) of the vehicle
You can actively contribute to the
reduction of the vehicle's energy
consumption by:
R driving conservatively
R maintaining the vehicle regularly
R decreasing the use of electrical
consumers
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
avoltage
supply, it must remain within a High-voltage battery

"Vehicle Homepage". For this reason, make
sure than no unauthorized persons have
access to your personal area.
After selling the vehicle, you are required
to delete the vehicle from your personal
area on the "Vehicle Homepage". You must
also destroy the vehicle verification code
(VVC) documents.
If you have bought a pre-owned vehicle, it
may be possible that the previous owner
still has access to the "Vehicle Homepage".
For this reason, have a new vehicle
verification code (VVC) reissued to you at
an authorized electric drive smart center
after purchase. With this new code you can
set up the access to your vehicle as
described in the "Personal area setup"
section. Here you can also deactivate the
previous owner's access ,should it still be
active.
Calling up the functions of the "Vehicle
Homepage" If the vehicle is registered in your
personal area of the "Vehicle Homepage",
you can, for example, access the following
functions:
R call up the current charge level
R program the departure time
R activate the "Air conditioning before
start" function
When the vehicle is being charged, you can
call up the estimated charging time and the
attainable range. Both results are
estimated values because, for example,
they are influenced by the following
factors:
R outside temperature
R active electrical consumers, e.g. air
conditioning, lights
R personal driving style
R traffic conditions
Plan for a sufficient reserve accordingly. Connecting the vehicle to the Internet
via powerline If you wish to use the "Vehicle Homepage"
at home, your vehicle must be able to access
the Internet
.This is possible via your DSL
router, for example. This connection is
established by means of the inserted
charging cable using powerline
technology.
The vehicle supports powerline
communicatio naccording to the "HomePlug
AV" standard. Data is transmitted via phase
L1 and the neutral conductor of the power
line.
In order for the vehicle to access the
Internet, you require a commercially
available adapter of the "HomePlug AV"
standard. This adapter must also have an
encryption button so that it can be
configured to communicate with the
vehicle. Connect the adapter to the power
supply as well as your Internet connection.
If the adapter is connected to different
phase than L1, a phase coupler must be
additionally installed. Only in this way
can stable communication be guaranteed.
For questions, consult a qualified
electrician.
i If you already have a powerline network
installed, the vehicle can be integrated
into it.
To establish a connection between the
vehicle and a powerline adapter, carry out
the following:
X Connect the vehicle to a power socket or
a wallbox.
The right 0004indicator lamp on the
vehicle socket must flash green.
X Insert the powerline adapter into a
neighboring power socket. Observe that
the vehicle and the adapter are
connected via phase L1.
X Switch on the ignition.
X Call up the Charge current menu on the
control system (Y page 88). High-voltage battery

If you leave the charging cable in the power

i You can also set the maximum charge
current via the control system
(Y page 88).
If differing values are set on the
charging cable and the control system,
the high‑voltage battery is charged
