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 certain ages in the front seat of a vehi-
cle 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 43) Additional protection potential is pro-
vided 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 0075in 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 0075
is not lit when the engine is running.
A malfunction in the system has been
detected if the SRS indicator lamp 0075
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
Modifications to or work improperly con-
ducted on restraint systems (such as seat 30
Occupant safety>> Safety.

belts and anchors, Emergency Tensioning
Devices, seat belt force limiters or air
bags) or their wiring, as well as tampering
with interconnected electronic systems,
can lead to the restraint systems no longer
functioning as intended. Air bags or Emer-
gency Tensioning Devices, for example,
could deploy inadvertently or fail to
deploy in accidents in which they other-
wise should deploy (although the deceler-
ation threshold for air bag deployment is
exceeded). Therefore, never modify the
restraint systems. Do not tamper with elec-
tronic components or their software. G
WARNING
In the event that the SRS indicator lamp
0075 comes on while driving or does not
come on at all, the SRS self-check has
detected a malfunction. For your safety, we
strongly recommend that you immediately
but safely pull the vehicle off of the road-
way and stop driving. Contact an authorized
electric drive smart center immediately to
have the system checked; otherwise the SRS
may not deploy when needed in an accident,
which could result in serious or fatal
injury, or it might deploy unexpectedly and
unnecessarily which could also result in
injury.
In addition, improper repair work on the
SRS creates a risk of rendering the SRS
inoperative or causing unintended air bag
deployment. Work on the SRS must therefore
only be performed by qualified techni-
cians. Contact an authorized electric drive
smart center. If it is necessary to modify
an air bag system to accommodate a person
with disabilities, contact your local
authorized electric drive smart center. Seat belts
The use of seat belts and infant and child
restraint systems is required by law in all
50 states, the District of Columbia, the U.S. territories and all Canadian provinces and
territories.
Even where this is not the case, all vehicle
occupants should have their seat belts fas-
tened whenever the vehicle is being oper-
ated.
For more information, see “Fastening the
seat belts” (Y
page 62).
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). G
WARNING
Always fasten your seat belt before driving.
Always make sure all of your passengers are
properly restrained.
Failure to wear and properly fasten and
position your seat belt greatly increases
your risk of injuries and their likely
severity in an accident. You and your
passenger should always wear seat belts.
If you are ever in an accident, your injuries
can be considerably more severe without
your seat belt properly buckled.
Without your seat belt buckled, you are
much more likely to hit the interior of the
vehicle or be ejected from it. You can be
seriously injured or killed.
In the same crash, the possibility of injury
or death is lessened if you are properly
wearing your seat belt. Air bags can only
protect you if you are properly wearing
your seat belt. G
WARNING
Never ride in a moving vehicle with the seat
backrest in an excessively reclined posi-
tion as this can be dangerous. You could
slide under the seat belt in a collision. If
you slide under it, the belt would apply
force at the abdomen or neck, causing ser-
ious or even fatal injuries. The seat back-
rest and seat belt provide the best
restraint when the wearer is in a position Occupant safety

that is as upright as possible and the belt
is properly positioned on the body. G
WARNING
Never let more people ride in the vehicle
than there are seat belts available. Make
sure everyone riding in the vehicle is cor-
rectly restrained with a separate seat belt.
Never use a seat belt for more than one per-
son at a time. G
WARNING
Seat belts of a vehicle involved in an acci-
dent must be inspected by smart. Only then
is it possible to determine whether the seat
belts were damaged or stressed in the acci-
dent. Damaged or stressed seat belts may
not properly protect you in a subsequent
accident.
Only use seat belts which have been
approved by smart.
Do not make any modifications to the seat
belts. This can lead to unintended activa-
tion of the Emergency Tensioning Devices
(ETDs) or to their failure to activate when
necessary.
Do not bleach or dye seat belts as this may
severely weaken them. In a crash, they may
not be able to provide adequate protection.
Have all work carried out only by qualified
technicians. Contact an authorized elec-
tric drive smart center. G
WARNING
USE SEAT BELTS PROPERLY
R Seat belts can only work when used prop-
erly. Never wear seat belts in any other
way than as described in this section, as
that could result in serious injuries in
case of an accident.
R Each occupant should wear their seat belt
at all times, because seat belts help
reduce the likelihood of and potential
severity of injuries in accidents,
including rollovers. The integrated
restraint system includes SRS (driver front air bag, passenger front air bag,
head-thorax air bags) and Emergency
Tensioning Devices (ETDs) with seat belt
force limiters.
The system is designed to enhance the
protection provided by secured seat
belts in certain frontal and side
impacts.
R Never wear the shoulder belt under your
arm, against your neck or off your
shoulder. Doing so may cause your body to
move too far forward in a frontal crash,
which would increase the chance of head
and neck injuries. The seat belt would
also apply too much force to the ribs or
abdomen, which could severely injure
internal organs such as your liver or
spleen.
R Never wear seat belts over rigid or
breakable objects in or on your clothing,
such as eyeglasses, pens, keys, etc., as
these might cause injuries.
R Position the lap belt as low as possible
on your hips and not across the abdomen.
If the lap seat belt is positioned across
your abdomen, it could cause serious
injuries in a crash.
R Never use a seat belt for more than one
person at a time. Do not fasten a seat belt
around a person and another person or
other objects at the same time.
R Seat belts should not be worn twisted. In
a crash, you would not have the full width
of the seat belt to manage impact forces.
The twisted seat belt against your body
could cause injuries.
R Pregnant women should also always use a
lap-shoulder belt. The lap belt portion
should be positioned as low as possible
on the hips to avoid any possible pres-
sure on the abdomen.
R Never place your feet on the instrument
panel, dashboard or on the seat. Always 32

keep both feet on the floor in front of the
seat.
R When using a seat belt to secure infant or
toddler restraints or children in booster
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 0075in
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 the
ignition 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. Occupant safety
