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

WARNING
When connected to a power supply socket, a
high electrical load during the charging
process can lead to overheating of the
external power supply. There is a risk of
fire.
Check the maximum permissible charge
current on site before you begin the charg-
ing process. Contact an authorized electric
drive smart center should you require
assistance. If necessary, adjust the set-
tings of your vehicle.
! An excessive charge current can blow a
fuse or lead to overheating of the exter-
nal power supply. Check whether the
external power supply is compatible
with the set charge current. If necessary,
lower the set charge current or use
another power socket. 0043

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).

/ 6 in (4 mm) on all four
wheels for the winter season to ensure nor-
mal balanced handling characteristics. On
packed snow, they can reduce your stopping
distance compared to summer tires.
Stopping distance, however, is still con-
siderably greater than when the road is not
covered with snow or ice. Exercise appro-
priate caution.
! Avoid spinning of a drive wheel for an
extended period when driving off on
slippery road surfaces. Otherwise, the
drivetrain could be damaged, which is
not covered by the smart Limited War-
ranty. Tire speed rating
Regardless of the tire speed rating, local
speed limits should be obeyed. Use prudent
driving speeds appropriate to prevailing
conditions. G
WARNING
Even when permitted by law, never operate
a vehicle at speeds greater than the maxi-
mum speed rating of the tires.
Exceeding the maximum speed for which
tires are rated can lead to sudden tire fail-
ure, causing loss of vehicle control and
possibly resulting in an accident and/or
personal injury and possible death, for you
and for others.
Make sure your tires have the required tire
speed rating as specified for your vehicle
in the “Technical data section”
(Y page 216), for example when purchasing
new tires.
For information on how to identify the tire
speed rating on a tire’s sidewall, see “Tire
size designation, load and speed rating”
(Y page 140).
If you are uncertain about the correct read-
ing of the information given on a tire’s sidewall, any authorized electric drive
smart center will be glad to assist you.
i
For information on speed ratings for
winter tires, see “All-season and winter
tires” (Y page 141). Winter driving instructions
The most important rule for slippery or icy
roads is to drive sensibly and to avoid
abrupt acceleration, braking and steering
maneuvers.
For information on driving with snow
chains*, see “Snow chains*” (Y page 146).
Road salts and chemicals can adversely
affect braking efficiency. Increased pedal
force may become necessary to produce the
normal braking effect.
Depressing the brake pedal periodically
when traveling at length on salt-strewn
roads can bring road-salt-impaired brak-
ing efficiency back to normal.
If the vehicle is parked after being driven
on salt-treated roads, the braking effi-
ciency should be tested as soon as possible
after driving is resumed. G
WARNING
Make sure not to endanger any other road
users when carrying out these braking
maneuvers. G
WARNING
The outside temperature display is not
designed to serve as an ice-warning device
and is therefore unsuitable for that pur-
pose. Indicated temperatures just above
the freezing point do not guarantee that the
road surface is free of ice.
