Occupant safety

>> Safety. 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 se

riously 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 lim

ited as are other two
seat vehicles, in the ex

tent 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 re

strained in the front seat of two seat vehicles.
Special instructions and warnings are provid

ed below about when and if you may restrain a
child in the passenger seat of the smart vehi

cle. 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 instruc

tions 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.
•Seat belts (

page 50)
• Child restraints (

page 66)
Additional protection potential provided by

Although independent systems, their
protective functions work in conjunction with
each other.

systems for infants and children, see
"Children in the vehicle" (

Occupant safety

>> Safety.
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 unfas

tened 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)
(
page 60).
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
• the system, based on OCS weight sensor
readings, senses that the passenger seat is
occupied and the 57 indicator
lamp is not lit (

page 64).
• 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.

Driver front air bag

Passenger front air bag
Occupant Classification SystemThe O
ccupant C
lassification S
ystem (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
The system does not deactivate the head

thorax air bag, the seat Emergency Tension

ing Devices, and the seat belt force limiters.
Occupants must sit properly belted in a posi

tion that is as upright as possible with their
back against the seat backrest and feet on the
floor to be correctly classified. If the occu

pant's weight is transferred to another object
in the vehicle (e.g. by leaning on armrests),
the OCS may not be able to properly approxi

mate the occupant’s weight category. P91.60

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 the57 indicator lamp as an
indication of whether or not the passenger is
properly positioned (

page 64).
G
Warning!
If the57 indicator lamp illu

minates 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
the57 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 classi

fied 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, the57 indicator
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,
the57 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 indi

vidual (such as a young teenager or a
small adult), the57 indica

tor 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 the57 indicator lamp
is illuminated, the passenger front air
bag is deactivated.
When the57 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.

Warning!
If the exterior lamp switch is set to

automatically switched on under foggy
conditions.
To minimize risk to you and to others,
activate headlamps by turning exterior
lamp switch to positionB when
driving or when traffic and/or ambient
lighting conditions require you to do so.
In low ambient lighting conditions, only
switch from positionU toB with
the vehicle at a standstill in a safe
location. Switching from positionU
toB will briefly switch off the
headlamps. Doing so while driving in low
ambient lighting conditions may result in
an accident.
The automatic headlamp feature is only
an aid to the driver. The driver is
responsible for the operation of the
vehicle’s lights at all times.
