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
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 warnings 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
equipped with technology to accomplish
this. Please pay very close attention to the
instructions and warnings below,
particularly 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
provided by:
R
Supplemental Restraint System (SRS)
with
- Air bags (Y page 33)
- Air bag control unit (with crash
sensors)
- 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 Occupant
Classification System (OCS)
(Y page 39)
Although independent systems, their
protective functions work in conjunction
with each other.
i For information on infants and
children 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 6 in the instrument
cluster comes on when the ignition is
switched on and goes out after
approximately 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
detected if the SRS indicator lamp 6
R fails to go out after approximately 4
seconds after the ignition was switched
on
R does not come on at all
R comes on after the engine was started or
while driving 30
Occupant safety
>> Safety.

How an air bag operates
An air bag is inflated in a matter of
milliseconds. If an air bag is triggered,
the SRS indicator lamp
6 in the
instrument cluster illuminates.
! If the air bags are activated, you will
hear a loud noise and some dust may be
generated. The explosion fundamentally
represents no risk to your hearing.
An
inflated air bag slows down and reduces
the movement of the occupant. When the
occupant makes contact with a front air bag
or head-thorax air bag (cabriolet only),
hot gas flows out of the inflated front air
bags and head-thorax air bags (cabriolet
only). This reduces the load on the
occupant’s head and upper body. These air
bags are consequently deflated after the
accident.
Driver front air bag/passenger front air
bag The front air bags are designed to reduce
the potential of injury in certain frontal
impacts.
Driver front air bag and passenger front
air bag are deployed
R
at the start of an accident with high
vehicle

deceleration in the longitudinal
direction
R independently of other air bags in the
vehicle being deployed
R never in the event of a rollover, unless
high vehicle deceleration in the
longitudinal direction is detected
i The front air bags in this vehicle have
been designed to inflate in two stages.
This allows the air bag to have different
rates of inflation that are based on the
rate of relevant vehicle deceleration
and a fastened or unfastened seat belt as
assessed by the air bag control unit.
On the passenger side, the front air bag
deployment is additionally influenced by the passenger’s weight category as
identified by the Occupant
Classification System (OCS)
(Y page 39).
The

lighter the passenger side occupant,
the higher the vehicle deceleration rate
required for the second stage inflation
of the air bag.
The air bags will not deploy in impacts
which do not exceed the system’s
deployment thresholds. In such instances,
the seat belts are designed to protect you.
The passenger air bag will only be
deployed if
R the system, based on OCS weight sensor
readings, senses that the passenger seat
is occupied and the 4 0
indicator lamp is not lit (Y page 41)
R the impact exceeds a preset deployment
threshold
The driver front air bag is located in the
steering wheel housing, the passenger
front air bag above the glove box. :

Occupant safety
>> Safety.

Thorax-pelvis side air bags are deployed
R
on the impacted side of the vehicle
R in instances with a high rate of lateral
vehicle deceleration or acceleration
R independently of the front air bags
R regardless
of whether the seat belt on the
impacted side of the vehicle is in use
R independently of the ETDs.
Thorax-pelvis side air bags will generally
not deploy in a rollover.
The thorax-pelvis side air bags will
deploy, however, if the system detects
R a high rate of lateral vehicle
deceleration or acceleration, and
R that air bag deployment can offer
additional protection to that provided
by the seat belt.
The thorax-pelvis side air bags are
integrated into the driver and passenger
seat backrests. :
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
occupant 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
R head-thorax air bag (cabriolet)
R the window curtain air bag (coupé)
R the thorax-pelvis side air bag (coupé)
R the seat Emergency Tensioning
Devices
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
leaning 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 smart
center. Only seat accessories approved
by smart may be used.
Both driver and the passenger should
always use the 4 0 indicator
lamp as an indication of whether or not
the passenger is properly positioned
(Y page 41). G
WARNING
If the 4 0 indicator lamp
illuminates when an adult or someone
larger than a small individual is in the
passenger seat, have the passenger re-
position himself or herself in the seat
until the 4 0 indicator lamp
goes out.
In the event of a collision, the air bag
control

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 Occupant safety

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 4 0 indicator
lamp will illuminate when the ignition is
switched on and remain illuminated,
indicating that the passenger front air bag
is deactivated.
When the OCS senses that the passenger seat
is classified as being empty, the
4 0 indicator lamp will
illuminate 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
4 0 indicator lamp will
illuminate for approximately 4 seconds
when the ignition is switched on and then,
depending on occupant weight sensor
readings from the seat, remains
illuminated or goes out.
When the 4 0 indicator lamp is
illuminated, the passenger front air bag is
deactivated.
When the 4 0 indicator lamp is
out and the passenger seat is occupied by
an adult or someone larger than a small
individual, the passenger front air bag is
activated.
When the OCS senses that the passenger seat
occupant is classified as an adult or
someone larger than a small individual, the
4 0 indicator lamp will
illuminate 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 4 0 indicator lamp is
illuminated, the passenger front air bag is
deactivated and will not be deployed. If the
4 0 indicator 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
identified by the OCS G
WARNING
Children 12 years old and under must be
seated and properly secured in an
appropriate infant or child restraint
recommended

for the size and weight of the
child.
The infant or child restraint must be
properly 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
appropriate 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
circumstances, even with the air bag
technology installed in your vehicle. 40
