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.
You can limit the charge current of the
high‑voltage battery. This can protect the
power supply from overloading. You can set
the limit either on the control unit of the

Overvoltage protection !
Overvoltage in the on-board powersup-
ply system can damage the vehicle.
The vehicle is therefore equipped with a
protective device against overvoltage in
the power supply system. This protective
device can be activated in severe thun-
derstorms, for example, and lead to
security systems being triggered. This
function is used to protect the vehicle.
Once the security system has been reac-
tivated, the charging process continues
automatically.
Reactivate the security system after it has
been triggered. Otherwise the charging
process will not continue. The high-volt-
age battery is not being charged, which may
result in the vehicle not being ready to
start.
If you have secured other devices using the
same security system, they will also be
deactivated after this is triggered. Make
sure that these devices do function after
reactivating the security system. Charging cable and ‑connecter warming Observe the safety notes on (Y
page 112).
Charging cable and ‑connecter can become
warmed during charging process when con-
nected to a power source.
This warming is caused by
R high charge currents
R charging time
R transfer resistances at the plug contacts
R resistances of the charging cable
If the infrastructure of the power supply
system and charging cable are in good
order, the charging cable and ‑connecter
will only warm up within admissible
threshold.
Damaged charging cable plug or its con-
tacts may lead to warming above admissi-
ble threshold. In case of this, have the
cable, respectively power socket,
exchanged or disposed by a qualified elec-
trician. Charging at an AC power socket or a
private wallbox

WARNING
If you apply improperly installed power
sockets or adapters, extension cables or
similar to connect the charging cable to
power sockets, this may cause fire or lead
to electric shock. Risk of life!
In order to avoid the risk, please observe
the following:
R Connect the charging cable only to power
sockets which are
-properly installed
- approved by a qualified electrician
R For safety reasons only use charging
cables which have been supplied and
approved for the vehicle.
R Do not use a damaged charging cable. 114

If you wish to charge economically and with
minimal damage to the battery, you must set
a departure time ( Ypage 90). This option
to optimize the charging process depends
on your electricity contract and the local
power supplier. Your vehicle detects this
option automatically. Depending on the
departure time which is set, the charging
process of the high-voltage battery may not
be started immediately or may be inter-
rupted during the process. Front compartment

The traction grades, from highest to low-
est, are AA, A, B, and C. Those grades rep-
resent the tire’s ability to stop on wet
pavement as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction perform-
ance.
Temperature G
WARNING
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, underinflation, or excessive load-
ing, either separately or in combination,
can cause excessive heat build-up and pos-
sible tire failure.
The temperature grades are A (the highest),
B, and C, representing the tire’s resistance
to the generation of heat and its ability to
dissipate heat when tested under control-
led conditions on a specified indoor lab-
oratory test wheel. Sustained high temper-
ature can cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to sudden
tire failure. The grade C corresponds to a
level of performance which all passenger
car tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades B
and A represent higher levels of perform-
ance on the laboratory test wheel than the
minimum required by law. Rotating tires
G
WARNING
Do not rotate front and rear wheels as they
have different dimensions, e.g. rim size,
wheel offset etc. Otherwise, the handling
can be affected and you could endanger
yourself and others. Thoroughly clean the mounting face of the
wheels and brake discs, i.e. the inner side
of the wheels/tires each time the wheels/
tires are changed. Check for and ensure
proper tire inflation pressure. G
WARNING
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
81 lb‑ft (110 Nm).
Only use genuine smart wheel bolts speci-
fied for your vehicle’s rims.
For information on wheel change, see “Flat

Before the onset of winter, have your vehi-
cle winterized at an authorized electric
drive smart center.
This service includes:
R Check of anticorrosion and antifreeze
concentration.
R Addition of washer concentrate to the
water of the windshield/rear window.
Use a windshield washer concentrate
labeled for winter which is formulated
for temperatures below freezing point
(Y page 218).
R 12 V battery test. The capacity of the
12 V battery test drops with decreasing
ambient temperature.
R Tire change. Winter tires
G
WARNING
Winter tires with a tread depth of less
than 1
/ 6 in (4 mm) must be replaced. They
are no longer suitable for winter opera-
tion.
Always use winter tires at temperatures
below 45 ¦(7¥) and whenever wintry road
conditions prevail. Not all M+S rated tires
provide special winter performance. Make
sure the tires you use show the mountain/
snowflake marking 004Don the tire side-
wall. These tires meet specific snow trac-
tion performance requirements of the Rub-
ber Manufacturers Association (RMA) and
the Rubber Association of Canada (RAC) and
have been designed specifically for use in
snow conditions. Use of winter tires is the
only way to achieve the maximum effective-
ness of the ABS and ESP ®
in winter opera-
tion.
For safe handling, make sure all mounted
winter tires are of the same make and have
the same tread design.
For information on winter tires for your
vehicle model, see the "Technical data"
section (Y page 216).
Always observe the speed rating of the win-
ter tires installed on your vehicle. If the
maximum speed for which your tires are
rated is below the speed rating of your
vehicle, you must place a notice to this
effect where it will be seen by the driver.
Such notices are available at your tire
dealer or any authorized electric drive
smart center. Snow chains*
! Remember that snow chains must always
be compatible with the tire sizes of a
vehicle. Snow chains that are approved
by smart are only permitted for the fol-
lowing tire size: 146

Wet road surface
G
WARNING
After driving in heavy rain for some time
without applying the brakes or through
water deep enough to wet brake components,
the first braking action may be somewhat
reduced and increased pedal pressure may
be necessary to obtain expected braking
effect. Maintain a safe distance from vehi-
cles in front.
To help prevent brake disc corrosion after
driving on wet road surfaces (particularly
salted roads), it is advisable to brake the
vehicle with considerable force prior to
parking. The heat generated serves to dry
the brakes. G
WARNING
Make sure not to endanger any other road
users when carrying out these braking
maneuvers.
Limited braking effect on salted roads Remember that the effect of the brakes can
be limited on salted road surfaces. A layer
of salt can form on brake discs and brake
pads, considerably reducing the friction
between the brake disc and the brake pad.
The effect is most noticeable after long
trips without braking, e.g. on the highway,
and after the vehicle has been parked for
several hours.
G
WARNING
The accumulation of salt on brake discs and
brake pads reduces braking effectiveness
and increases the distance necessary to
come to a complete standstill. This could
potentially cause an accident and/or per-
sonal injury.
To avoid this risk, you should
R brake carefully every now and then on
salted roads in order to remove any layer
of salt on the brake disc and brake pad, but do so without endangering any other
road users
R keep a good safe distance from the vehi-
cle in front and drive carefully
R press the brake carefully at the end of the
trip and again when beginning the next
trip in order to remove any salt residues
from the brake disc
New brake pads Only install brake pads recommended by
smart.
G
WARNING
If other than recommended brake pads are
installed, or other than recommended brake
fluid is used, the braking properties of the
vehicle can be degraded to an extent that
safe braking is substantially impaired.
This could result in an accident. G
WARNING
New brake pads will not achieve their opti-
mal braking effect until after several hun-
dred miles (kilometers). This means that
you must compensate for the reduced brak-
ing effect by pressing harder on the brake
pedal and adapt your driving style accord-
ingly. The same applies after brake pads or
brake discs have been changed. Drive sensibly - save energy
Energy consumption, to a great extent,
depends on driving habits and operating
conditions.
To save energy you should:
R Drive carefully and maintain a suitable
distance from the vehicle in front.
R Avoid frequent acceleration and decel-
eration.
R Keep tires at the recommended inflation
pressures.
R Remove carriers* when not in use. Driving instructions
