Protection of the environment
General notes
HEnvironmental note
Daimler's declared policy is one of inte-
grated environmental protection.
The objectives are for the natural resour-
ces which form the basis of our existence on
this planet to be used sparingly and in a
manner which takes the requirements of
both nature and humanity into account.
You too can help to protect the environment
by operating your vehicle in an environ-
mentally responsible manner.
Energy consumption and the rate of engine,
transmission, brake and tyre wear depend
on the following factors:
Roperating conditions of your vehicle
Ryour personal driving style
You can influence both factors.
You should bear the following in mind:
Operating conditions
Rmake sure that the tyre pressures are
always correct.
Rdo not carry any unnecessary weight.
Rkeep an eye on the vehicle's energy con-
sumption.
Rremove rear racks once you no longer
need them.
Ra regularly serviced vehicle will con-
tribute to environmental protection. You
should therefore adhere to the service
intervals.
Ralways have maintenance work carried
out at a specialist workshop that is
qualified to work on smart electric drive
vehicles.
Personal driving style
Rdrive carefully and maintain a safe dis-
tance from the vehicle in front.
Ravoid frequent, sudden acceleration.
HEnvironmental note
Have a defective high-voltage battery dis-
posed of in an environmentally-responsi-
ble manner. Contact a specialist workshop
that is qualified to work on smart electric
drive vehicles and has the necessary spe-
cialist knowledge and tools to carry out the
work required. smart recommends that you
use a smart Centre for this purpose.
Returning an end-of-life vehicle
EU countries only:
smart will take back your old vehicle to
dispose of it in an environmentally-
responsible manner in accordance with the
European Union (EU) End of Life Vehicles
Directive.
There is a network of return points and
disassembly plants available. In these
plants you can return your vehicle free of
charge. This makes a valuable contribution
to the recycling process and the conserva-
tion of resources.
For further information on recycling old
vehicles, recovery and the terms of the pol-
icy, visit the smart homepage.
Product information
smart recommends that you use genuine
smart parts, conversion parts and accesso-
ries that have been approved for your par-
ticular vehicle.
smart tests genuine parts and conversion
parts and accessories that have been spe-
cifically approved for your vehicle for
their reliability, safety and suitability.
Despite ongoing market research, smart is
unable to assess other parts. smart there-
fore assumes no responsibility for the use
of other parts in smart vehicles. This is
also the case, even if they have been inde-
pendently or officially approved. The use
12 >> Introduction.

of non-approved parts could affect your
vehicle's operating safety.
smart therefore recommends genuine smart
parts, conversion parts and accessories
that have been approved for your particular
vehicle.
smart genuine parts and approved conver-
sion parts and accessories can be obtained
from any smart Centre. Here, you will
receive advice about permissible techni-
cal modifications, and the parts will be
professionally fitted.
Owner's Manual
General notes
Before you first drive off, read this Own-
er's Manual carefully and familiarise
yourself with your vehicle.
For your own safety and a longer vehicle
life, follow the instructions and warning
notices in this manual. Disregarding them
may lead to damage to the vehicle or per-
sonal injury.
Vehicle equipment
This Owner's Manual describes all models
and all standard and optional equipment of
your vehicle available at the time of pub-
lication of the Owner's Manual. Country-
specific differences are possible. Please
note that your vehicle may not be equipped
with all features described. This also
applies to safety-relevant systems and
functions. The equipment in your vehicle
may therefore differ from that shown in the
descriptions and illustrations. All the
systems found in your vehicle are listed in
the original purchase agreement of your
vehicle. Should you have any questions
concerning equipment and operation,
please consult a smart Centre.
Operating safety
Important safety notes
GWARNING
All work on the vehicle and, in particular,
work relevant to safety or on safety-related
systems must be carried out at a specialist
workshop that is qualified to work on smart
electric drive vehicles. The specialist
workshop must have the necessary special-
ist knowledge and tools to carry out the
work required. smart recommends a smart
Centre for this purpose.
GWARNING
Some safety systems only function when the
ignition is switched on. Therefore, do not
switch off the engine when driving. Other-
wise, the safety systems of your vehicle may
not function correctly and as a result will
no longer protect you and other persons as
intended. There is also a risk of losing
control of your vehicle and causing an
accident.
GWARNING
If you drive over obstacles at high speed or
if the vehicle bottoms out in rough terrain,
this could cause heavy impacts to the vehi-
cle underbody, tyres or wheels. Your vehi-
cle may thereby be damaged and as a result
you could cause an accident.
Therefore, drive over obstacles slowly.
Avoid the vehicle bottoming out off-road
and, if necessary, have your vehicle
checked at a specialist workshop.
Vehicles with an electric motor generate
much less driving noise than vehicles with
internal combustion engines. As a result,
your vehicle may not be heard by other road
users in certain situations. This can hap-
pen, for example, when you are parking and
your vehicle is not seen by other road
users.
This requires you to adopt a particularly
anticipatory driving style, as it is neces-
>> Introduction. 13

sary to allow for the possibility that other
road users may behave erratically.
On vehicles equipped with "Acoustic Vehi-
cle Indication"*, a sound generator pro-
duces a noise (Y page 45). The vehicle can
be heard better as a result.
Diagnostics connection
GWARNING
If you connect equipment to a diagnostics
connection, it can affect the operation of
the vehicle systems. This could compromise
the operating safety of your vehicle while
driving. There is a risk of an accident.
Do not connect any equipment to a diagnos-
tics connection.
GWARNING
Loose equipment or cables hanging from a
device which are connected to a diagnostic
connection could impede pedal clearance.
The equipment or cables could get caught
between the pedals when driving and brak-
ing suddenly. This could impair the func-
tion of the pedals. There is a risk of acci-
dent.
Do not attach any equipment or cables in the
driver's footwell.
! If the engine is switched off and equip-
ment on the diagnostics connection is
used, the starter battery may discharge.
The diagnostics connection is only inten-
ded for the connection of diagnostic
equipment at a qualified specialist work-
shop.

out at a specialist workshop that is quali-
fied to work on smart electric drive vehi-
cles.
GWARNING
If work on electronic equipment and its
software is carried out incorrectly, this
equipment could stop working. The elec-
tronic systems are networked via interfa-
ces. Tampering with these electronic sys-
tems could cause malfunctions in systems
which have not been modified. Malfunc-
tions such as these can seriously jeopard-
ise the vehicle's operating safety and
therefore your own safety.
Therefore, always have work on and altera-
tions to electronic components carried out
at a specialist workshop that is qualified
to work on smart electric drive vehicles.

coupling.
High-voltage electrical system
Danger of electric shock
GDANGER
The vehicle's high voltage electrical sys-
tem is under high voltage. If you modify
components in the vehicle's high-voltage
electrical system or touch damaged compo-
nents, you may be electrocuted. The compo-
nents in the vehicle's high-voltage elec-
trical system may be damaged in an acci-
dent, although the damage is not visible.
There is a risk of fatal injury.
Do not touch any high-voltage components
after an accident and never modify the
vehicle's high-voltage electrical system.
Have the vehicle towed away after an acci-
dent and the vehicle's high-voltage elec-
trical system checked by a qualified spe-
cialist workshop.
All of the vehicle's high-voltage electri-
cal system components are marked with yel-
low warning stickers which warn you of the
dangers of high voltages. The cables of the
vehicle's high-voltage electrical system
are orange in colour.
When performing general work on the vehi-
cle, such as replacing bulbs or checking
the coolant level, make sure that:
Rthe ignition is switched off
Rthe charging cable for charging the
high-voltage battery is disconnected
Automatically switching off the vehi-
cle's high-voltage electrical system
The vehicle's high-voltage electrical sys-
tem is switched off automatically if:
Rthe restraint systems are activated in
the event of an accident.
Ran electrical short circuit is detected
in the vehicle's high-voltage electrical
system.
Ran electrical connection in the vehicle's
high-voltage electrical system is dis-
connected.
This is to ensure that you do not come into
contact with high voltage.
High-voltage battery
GWARNING
In the event of a vehicle fire, the internal
pressure of the high-voltage battery could
exceed a critical value. In this case, flam-

mable gas escapes through a vent valve in
the vehicle's underbody. The gas can
ignite. There is a risk of injury.
Leave the danger area immediately. Secure
the danger area at a suitable distance,
whilst observing legal requirements.
GWARNING
If the housing of the high-voltage battery
has been damaged, electrolyte and gases
may leak out. These are poisonous and caus-
tic. There is a risk of injury.
Avoid contact with the skin, eyes or cloth-
ing. Immediately rinse electrolyte
splashes off with water and seek medical
attention straight away.
High-voltage disconnect device
Your vehicle is equipped with a high-volt-
age disconnect device : which can be used
to switch off the vehicle's high-voltage
electrical system.
! The vehicle's high-voltage electrical
system must only be switched off when the
vehicle is stationary by specially
trained technicians. The vehicle's high-
voltage electrical system may otherwise
be damaged.
Correct use
Observe the following information when
using the vehicle:
Rall safety information contained in
these operating instructions
Rthe "Technical data" section in this
Owner's Manual
Rnational road traffic regulations
Rnational road traffic licensing regula-
tions
GWARNING
Various warning stickers are affixed to
your vehicle. Their purpose is to draw your
attention, and the attention of others, to
various dangers. Therefore, do not remove
any warning stickers unless the sticker
clearly states that you may do so.
If you remove the warning stickers, you or
others could be injured by failing to rec-
ognise certain dangers.
QR codes for rescue card
The QR code is secured in the fuel filler
flap and on the opposite side on the B-pil-
lar. In the event of an accident, rescue
services can use the QR code to quickly find
the appropriate rescue card for your vehi-
cle. The current rescue card contains, in a
compact form, the most important informa-
tion about your vehicle, e.g. the routing of
the electric cables.

Data stored in the vehicle
A large number of your vehicle's electronic
components contain data memory.
16 >> Introduction.

The data memory temporarily or perma-
nently stores technical information about:
Rthe vehicle's operating state
Revents
Rfaults
The technical information generally docu-
ments the condition of a component, mod-
ule, system or the environment.
This information includes, for example:
RThe operating status of system compo-
nents, including, for instance, fluid
levels, battery charge levels.
RStatus messages concerning the vehicle
and its individual components, includ-
ing, for instance, the number of wheel
revolutions/speed, deceleration in
movement, lateral acceleration.
RMalfunctions and defects in key system
components, including, for instance,
lights, brakes.
RThe vehicle's responses in particular
driving situations, including, for
instance, deployment of an airbag, use of
stability control systems.
REnvironmental conditions, including,
for instance, the outside temperature.
This information is exclusively of a tech-
nical nature and is used to:
Rassist in the detection and elimination
of faults and defects
Roptimise vehicle functions
The data cannot be used to trace the vehi-
cle's movements.
If you have the vehicle serviced, this tech-
nical information can be read out from the
event and fault data memory.
Service includes, for example:
Rrepair work
Rservice work
Rwarranty claims
Rquality assurance
The readout is handled by service network
staff (including the manufacturer) with the
help of special diagnostic testers. You can
obtain more detailed information, if
required.
After the fault has been rectified, the
information is cleared in the fault memory
or is sequentially overwritten.
During vehicle operation, certain situa-
tions may arise in which this technical
data - in conjunction with other informa-
tion and, if applicable, after consultation
with an approved assessor - may be linked
to an individual person.
Examples of this include:
Raccident reports
Rvehicle damage
Rwitness reports
In the case of electric vehicles which can
communicate charging information, data
related to charging and the charge status
are transmitted to the charging station and
manufacturer. This facilitates intelligent
charging and the implementation of con-
venience functions for customers. Some of
this data is available to customers via the
Vehicle Homepage (Y page 88).
In addition, battery usage data is trans-
mitted to the manufacturer in set intervals
for quality control and product improve-
ment purposes.
The data is transmitted via:
Rthe communications function
Ra mobile communications module inte-
grated in the vehicle (if the vehicle is
equipped with it)
Additional functions that have been con-
tractually agreed upon with the customer
also make it possible to transmit particu-
lar vehicle data from the vehicle. These
additional functions include, for
instance, a vehicle locating feature in the
event of emergencies.
