partner which is qualified for smart elec-
tric drive.
Particular care should be taken involving
all areas which are in the vicinity of high
voltage parts, e.g. parts in the engine com-
partment. Orange-colored cables and their respective sockets carry high voltage and
must not be damaged.
Serious injury or death can result if you:
R remove the covers of components which
are labeled with a warning sticker.
R handle components of the high-voltage
vehicle electrical system.
R open the housing.
R disconnect plug connectors.
R come into contact with components or
orange-colored cables of the high-volt-
age vehicle electrical system following
an accident.
R come into contact with orange-colored
cables or their damaged plug connectors.
R come into contact with damaged compo-
nents of the high-voltage vehicle elec-
trical system.
Have the damaged orange-colored cables or their damaged plug connectors replaced
immediately at an authorized electric
drive smart center. The service partner
must have the required knowledge and tools
to carry out the necessary work. For safety
reasons, smart recommends using a smart
center which is qualified for smart elec-
tric drive. Particularly for safety-rele-
vant work and work on safety-relevant vehi- cle systems, servicing by an authorized
electric drive smart center is essential.
Do not remove the high-voltage battery of
the high-voltage vehicle electrical sys-
tem. Have the required work carried out by
an authorized electric drive smart center.
smart recommends that you use an author-
ized electric drive smart center. G
WARNING
The high‑voltage battery of the drive sys-
tem is located under the vehicle’s under-
body. When the pressure inside the
high‑voltage battery exceeds a certain
value, for example in case of a vehicle fire, inflammable gas will escape via a duct. Theinflammable gas escapes to an area under
the vehicle. This prevents the high‑voltage
battery from exploding.
Stay away from this area of the vehicle.
When you carry out common works like
replacing bulbs or checking coolant level,
make sure that
R the ignition is switched off
R the charging cable for the high-voltage
battery is disconnected. Automatic switch-off of the high-volt-
age system
The high-voltage system will be automati- cally switched off, in the event:
R of an accident in which the restraint
systems are triggered
R of a short circuit in the high-voltage
system is detected
R that an electric connection in the high-
voltage system has been disconnected
This helps to avoid that you get in contact
with high-voltage. High-voltage battery

Occupant safety
Introduction
The smart vehicle is equipped with seat
belts and dual stage air bags to protect you
in a crash. However, children can be killed or seriously injured by an inflating air
bag. Indeed, there is a stronger risk of
serious death or bodily injury when an air
bag deploys on a child positioned in a
rear-facing child seat in the passenger
seat. Because this vehicle has only two
front seats and no backseat, it is limited as are other two-seat vehicles, in the extent
to which it may restrain children traveling
in the passenger front seat. Many states
have laws against placing children of cer- tain ages in the front seat of a vehicle that
has both front and back seats. Those laws
make exceptions to permit children to be
restrained in the front seat of two seat
vehicles. Special instructions and warn-
ings are provided below about when and if
you may restrain a child in the passenger
seat of the smart vehicle. Under certain
circumstances, it is appropriate for the
passenger air bag not to operate when a
child is restrained in a car seat in the
passenger seat, and this vehicle is equip- ped with technology to accomplish this.
Please pay very close attention to the
instructions and warnings below, particu-
larly as they relate to children.
In this section you will learn the most
important facts about the restraint system components of the vehicle.
The restraint systems are:
R Seat belts (Y page 31)
R Child restraints (Y page 42) Additional protection potential is provi-
ded by:
R Supplemental RestraintSystem (SRS)
with
- Air bags (Y page 33)
- Air bag control unit (with crash sen-
sors)
- Emergency Tensioning Devices and
seat belt force limiters (Y page 33)
R Air bag system components with
- Passenger front air bag off indicator
lamp (Y page 41)
- Passenger seat with OccupantClassi-
fication System (OCS) (Y page 39)
Although independent systems, their pro-
tective functions work in conjunction with each other.
i For information on infants and chil-
dren traveling with you in the vehicle
and restraint systems for infants and
children, see “Children in the vehicle”
(Y page 42).
The SRS system conducts a self-test when
the ignition is switched on and in regular intervals while the engine is running. This facilitates detection of malfunctions. The
SRS indicator lamp 6in the instrument
cluster comes on when the ignition is
switched on and goes out after approx-
imately four seconds.
The SRS components are in operational
readiness if the SRS indicator lamp 6
is not lit when the engine is running.
A malfunction in the system has been detec- ted if the SRS indicator lamp 6
R fails to go out after approximately 4 sec-
onds after the ignition was switched on
R does not come on at all
R comes on after the engine was started or
while driving G
WARNING

seats, always follow the child seat man-
ufacturer’s instructions. Emergency Tensioning Devices (ETDs)
and seat belt force limiters
The seat belts are equipped with Emer-
gency Tensioning Devices and seat belt
force limiters.
Emergency Tensioning Devices are
designed to activate in the following
cases:
R in frontal or rear-end impacts exceed-
ing the system deployment threshold
R if the restraint systems are operational
and functioning correctly
R in collisions with high vehicle decel-
eration/acceleration in the longitudi-
nal direction, e.g. a head-on collision
R on passenger side when the seat is occu-
pied and the seat belt is fastened
R independently of the front air bags
When activated, Emergency Tensioning
Devices remove slack from the seat belts in such a way that the seat belts fit more
snugly against the body. Seat belt force
limiters, when activated, reduce the force
exerted by the seat belts on occupants dur-
ing a crash.
When the emergency tensioning device is
triggered, the SRS indicator lamp 6in
the instrument cluster illuminates, see
“SRS indicator lamp” (Y page 169).G
WARNING
Once they have been triggered, Emergency
Tensioning Devices will no longer function properly and must be replaced. smart rec-
ommends that you visit a qualified work-
shop to have this done. In particular, work
relevant to safety or on safety-related sys-tems must be carried out at a qualified
specialist workshop.
Comply with safety regulations when dis-
posing of Emergency Tensioning Devices. These regulations are available at any
smart center.
The belt force limiter is designed to oper- ate in unison with the front air bag, which
absorbs a portion of the seat belt’s decel-
erating forces, distributing the load over
a larger area.
In the event of a head-on or rear-end col-
lision, the emergency tensioning device is
activated if the vehicle is decelerated or
accelerated sufficiently in the longitudi- nal direction at the start of impact with theignition switched on. Air bags
Air bags can reduce the severity of inju-
ries in serious collisions, e.g. in a head-
on collision or a side impact. G
WARNING
Air bags are designed to reduce the poten- tial of injury in certain frontal impacts
(front air bags and knee bags), or side
impacts (head-thorax air bags, window
curtain air bags and thorax-pelvis air
bags) which may cause significant inju-
ries. However, no system available today
can completely eliminate injuries and
fatalities.
The deployment of the air bags temporarily
releases a small amount of dust from the air
bags. This dust is neither injurious to your health, nor does it indicate a fire in the
vehicle. The dust might cause some tempo-
rary breathing difficulty for people with
asthma or other breathing trouble. To avoid
this, you may wish to get out of the vehicle
as soon as it is safe to do so. If you have any
breathing difficulty but cannot get out of
the vehicle after the air bag inflates, then get fresh air by opening a window or door. G
WARNING
To reduce the risk of injury when the front
air bags inflate, it is very important for Occupant safety

Thorax-pelvis side air bags Occupant Classification System
The Occupant Classification System (OCS)
automatically turns the passenger front air bag on or off based on the classified occu-pant weight category determined by weight
sensor readings from the passenger seat.
i Based on the classified occupant
weight category determined by weight
sensor readings from the passenger seat,
the system does also deactivate

ces
R the seat belt force limiter.
Occupants must sit properly belted in a
position that is as upright as possible with their back against the seat backrest and
feet on the floor to be correctly classified.
If the occupant’s weight is transferred to
another object in the vehicle (e.g. by lean-
ing on armrests), the OCS may not be able to properly approximate the occupant’s
weight category.
i If the seat, including the trim cover and
cushion, needs to be serviced in any way, take the vehicle to an authorized elec- tric drive smart center. Only seat acces-
sories approved by smart may be used.
Both driver and the passenger should
always use the 40indicator
lamp as an indication of whether or not
the passenger is properly positioned
(Y page 41). G
WARNING
If the 40indicator lamp illu-
minates when an adult or someone larger
than a small individual is in the passenger seat, have the passenger re-position him-
self or herself in the seat until the
40indicator lamp goes out.
In the event of a collision, the air bag con- trol unit will not allow passenger front air
bag deployment when the OCS has classified
the passenger seat occupant as being up to
or less than the weight of a typical
12‑month‑old child in a standard child
restraint, or if the passenger seat is
sensed as being empty.
When the OCS senses that the passenger seat occupant is classified as being up to or
less than the weight of a typical
12‑month‑old child in a standard child
restraint, the 40indicator
lamp will illuminate when the ignition is
switched on and remain illuminated, indi-
cating that the passenger front air bag is
deactivated.
When the OCS senses that the passenger seat is classified as being empty, the
40indicator lamp will illu-
minate and remains illuminated.
When the OCS senses that the passenger seat occupant is classified as being heavier
than the weight of a typical 12‑month‑old
child seated in a standard child restraint
or as being a small individual (such as a
young teenager or a small adult), the
40indicator lamp will illu-
minate for approximately 4 seconds when
the ignition is switched on and then,

When the 40indicator lamp is
illuminated, the passenger front air bag is
deactivated.
When the 40indicator lamp is
out and the passenger seat is occupied by an adult or someone larger than a small indi-
vidual, the passenger front air bag is acti-
vated.
When the OCS senses that the passenger seat occupant is classified as an adult or some- one larger than a small individual, the
40indicator lamp will illu-
minate for approximately 4 seconds when
the ignition is switched on and then goes
out, indicating that the passenger front air
bag is activated.
If the 40indicator lamp is
illuminated, the passenger front air bag is
deactivated and will not be deployed.
If the 40indicator lamp is not
illuminated, the passenger front air bag is
activated and will be deployed
R in the event of certain frontal impacts
R if impact exceeds a preset deployment
threshold
R independently of the head-thorax air
bags
If the passenger front air bag is deployed, the rate of inflation will be influenced by
R the rate of vehicle deceleration and a
fastened or unfastened seat belt as
assessed by the air bag control unit
R the passenger’s weight category as iden-
tified by the OCS G
WARNING
Children 12 years old and under must be
seated and properly secured in an appro-
priate infant or child restraint recommen- ded for the size and weight of the child.
The infant or child restraint must be prop-
erly secured with the vehicle’s seat belt, fully in accordance with the child seat
manufacturer’s instructions.
Children can be killed or seriously injured by an inflating air bag. Note the following
important information:
R Your vehicle is equipped with air bag
technology designed to turn off the
passenger front air bag in your vehicle
when the system senses the weight of a
typical 12‑month‑old child or less along
with the weight of a standard appropri-
ate child restraint on the passenger seat.
R A child in a rear-facing child restraint
on the passenger seat will be seriously
injured or even killed if the passenger
front air bag inflates in a collision
which could occur under some circum-
stances, even with the air bag technology
installed in your vehicle.
R If you install a rear-facing child
restraint on the passenger seat, make
sure the 40indicator lamp
is illuminated, indicating that the
passenger front air bag is deactivated.
Should the 40indicator
lamp not illuminate or go out while the
restraint is installed, please check
installation.
Periodically check the 40
indicator lamp while driving to make
sure the 40indicator lamp
is illuminated.
If the 40indicator lamp
goes out or remains out, do not transport a child on the passenger seat until the
system has been repaired.
A child in a rear-facing child restraint
on the passenger seat may be seriously
injured or even killed if the passenger
front air bag inflates.
R If you place a child in a forward-facing
child restraint on the passenger seat,
move the seat as far back as possible, use
the proper child restraint recommended
for the age, size and weight of the child 40

Driving safety systems
Introduction
G
WARNING
The following factors increase the risk of
accidents:
R Excessive speed, especially in turns
R Wet and slippery road surfaces
R Following another vehicle too closely
The driving safety systems described in
this section cannot reduce these risks or
prevent the natural laws of physics from
acting on the vehicle.
Always adapt your driving style to the pre- vailing road and weather and traffic con-
ditions and keep a safe distance to other
road users and objects on the street.
i In winter operation, the maximum
effectiveness of the ABS, the hydraulic
brake assistant, and the ESP ®
is only ach-
ieved with winter tires (Y page 146) or
snow chains* as required. Antilock Brake System (ABS)
G
WARNING
Do not pump the brake pedal. Use firm,
steady brake pedal pressure instead. Pump- ing the brake pedal defeats the purpose of
the ABS and significantly reduces braking
effectiveness.
The Antilock BrakeSystem (ABS) regulates
the brake pressure so that the wheels do not lock during braking. This allows you to
maintain the ability to steer your vehicle.
On slippery road surfaces, the ABS will
respond even to light brake pressure.
The ABS indicator lamp in the instrument
cluster (Y page 24) comes on when you
switch on the ignition. It goes out when the drive system is active. Braking At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in the
brake pedal, indicating that the ABS is
regulating the brake pressure.
X Keep firm and steady pressure on the
brake pedal while experiencing the pul-
sation.
Continuous, steady brake pedal pressure
yields the advantages provided by the ABS,
namely braking power and the ability to
steer the vehicle.
A pulsating brake pedal can be an indica-
tion of hazardous road conditions and
functions as a reminder to take extra care
while driving.
Emergency brake maneuver X
Keep continuous full pressure on the
brake pedal. G
WARNING
When the ABS is malfunctioning, the
hydraulic brake assistant and the ESP ®
are
also switched off.
When the ABS is malfunctioning, the wheels may lock during hard braking, reducing
steering capability and extending the
braking distance. G
WARNING
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can it increase braking or steering efficiency beyond that afforded by the condition of the
vehicle brakes and tires or the traction
afforded. The ABS cannot prevent acci-
dents, including those resulting from
excessive speed in turns, following
another vehicle too closely, or hydroplan-
ing. Only a safe, attentive, and skillful
driver can prevent accidents. The capabil- ities of an ABS equipped vehicle must never
be exploited in a reckless or dangerous 46

manner which could jeopardize the user’s
safety or the safety of others. Electronic Stability Program (ESP
®
)
Your vehicle is equipped with the Elec-
tronic Stability Program (ESP ®
). The ESP ®
is operational as soon as the drive system
is switched on and it monitors the vehicle’s traction (force of adhesive friction
between the tires and the road surface) and
handling.
The ESP ®
recognizes when a wheel is spin-
ning or if the vehicle starts to skid. By
applying brakes to the appropriate wheel
and by limiting the power output, the ESP ®
works to stabilize the vehicle. The ESP ®
is
especially useful while driving off and on
wet or slippery road surfaces. The ESP ®
also
stabilizes the vehicle during braking and
steering maneuvers.
The ESP ®
warning lamp ÷in the instru-
ment cluster flashes when the ESP ®
is
engaged.
The ESP ®
warning lamp ÷in the instru-
ment cluster comes on when you switch on
the ignition. It goes out when the drive
system is active.
Depending on the driving situation, the
ESP ®
R reduces the speed
R selectively brakes individual wheels
R equalizes the speed of the driven wheels
R stabilizes the vehicle when braking
R assists you in evasive maneuvers on all
roads G
WARNING
If the ESP ®
warning lamp ÷in the
instrument cluster flashes, proceed as fol-
lows:
R While driving off, apply as little throt-
tle as possible.
R While driving, ease up on the accelerator
pedal.
R Adapt your speed and driving style to the
prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid.
The ESP ®
cannot prevent accidents result-
ing from excessive speed. G
WARNING
The ESP ®
cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase the traction afforded. The ESP ®
cannot prevent accidents, including those
resulting from excessive speed in turns, or
hydroplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The
capabilities of an ESP ®
equipped vehicle
must never be exploited in a reckless or
dangerous manner which could jeopardize
the user’s safety or the safety of others.
! Because the ESP ®
operates automati-
cally, the ignition must be switched off
when the parking brake is being tested
on a brake test dynamometer. Active
braking action through the ESP ®
may oth-
erwise seriously damage the brake sys-
tem which is not covered by the smart
Limited Warranty.
