Seat belts
Introduction
Seat belts are the most effective means of
restricting the movement of vehicle occu-
pants in the event of an accident or the vehi-
cle rolling over. This reduces the risk of
vehicle occupants coming into contact with
parts of the vehicle interior or being ejected
from the vehicle. Furthermore, the seat belt
helps to keep the vehicle occupant in the best
position in relation to the air bag.
The seat belt system comprises:
RSeat belts
REmergency Tensioning Devices and seat
belt force limiters
If the seat belt is pulled by the seat belt
guide quickly or with a jerky movement, the
belt retractor locks. The belt strap cannot be extracted any further.
The Emergency Tensioning Device tightens
the seat belt in an accident, pulling the belt
close against the body. However it does not
pull the vehicle occupant back in the direc-
tion of the backrest.
The Emergency Tensioning Device does not
correct an incorrect seat position or the
routing of an incorrectly fastened seat belt.
When triggered, a seat belt force limiter
helps to reduce the force exerted by the seat
belt on the vehicle occupant.
The seat belt force limiters are synchronized
with the front air bags which absorb part of
the deceleration force. This can reduce the
force exerted on the vehicle occupants during
an accident.
!If the front-passenger seat is unoccu-
pied, do not insert the belt tongue into the
buckle of the front-passenger seat. This
may otherwise lead to the triggering of the
Emergency Tensioning Device in the event
of an accident, which will then need to be
replaced.
Important safety notes
The use of seat belts and child restraint sys-
tems is required by law in:
Rall 50 states
Rthe U.S. territories
Rthe District of Columbia
Rall Canadian provinces
Even where this is not required by law, all
vehicle occupants should correctly fasten
their seat belts before starting the journey.
GWARNING
If the seat belt is incorrectly fastened, it
cannot protect as intended. Furthermore,
an incorrectly fastened seat belt can cause
additional injury, for example, in an acci-
dent, during braking or when abruptly
changing direction. This poses an
increased risk of injury or even fatal
injury.
Make sure that all vehicle occupants are
seated properly with a correctly fastened
seat belt.
GWARNING
The seat belt does not offer the intended
level of protection if you have not moved
the backrest to an almost vertical position.
When braking or in the event of an accident,
you could slide underneath the seat belt and
sustain abdomen or neck injuries, for
example. This poses an increased risk of
injury or even fatal injury.
Adjust the seat properly before beginning
your journey. Always ensure that the back-
rest is in an almost vertical position and
that the shoulder section of your seat belt
is routed across the center of your shoul-
der.
GWARNING
Persons under 5 ft (1.50 m)in height cannot
fasten the seat belt correctly without an
additional suitable restraint system. If
the seat belt is incorrectly fastened, it
cannot protect as intended. Furthermore,
an incorrectly fastened seat belt can cause

additional injury, for example, in an acci-
dent, during braking or an abrupt change of
direction. This poses an increased risk of
injury or even fatal injury.
For this reason, always secure persons
under 5 ft (1.50 m) in height in suitable
restraint systems.
If a child younger than twelve years old and
under 5 ft (1.50 m) in height is traveling in the
vehicle:
Ralways secure the child in a child restraint
system suitable for this smart vehicle. The
child restraint system must be appropriate
to the age, weight and size of the child
Ralways observe the instructions and safety
notes on "Children in the vehicle"
(
Ypage 42) in addition to the child
restraint system manufacturer's installa-
tion and operating instructions
Rbe sure to observe the instructions and
safety notes on the "Occupant classifica-
tion system (OCS)" (
Ypage 36)
GWARNING
The seat belts may not perform their inten- ded protective function if:
Rthey are damaged, modified, extremely
dirty, bleach or dyed
Rthe seat belt buckle is damaged or
extremely dirty
Rthe Emergency Tensioning Devices, belt
anchorages or inertia reels have been
modified
Seat belts may sustain non-visible damage
in an accident, e.g. due to glass splinters.
Modified or damaged seat belts may tear or
fail, e.g. in an accident. Modified Emer-
gency Tensioning Devices could acciden-
tally trigger or fail to deploy when neces-
sary. This poses an increased risk of injury
or even fatal injury.
Never modify the seat belts, Emergency
Tensioning Devices, belt anchorages or
inertia reels. Make sure that the seat belts
are undamaged, not worn out and clean. Fol-
lowing an accident, have the seat belts
checked immediately at a qualified spe-
cialist workshop.
Only use seat belts that have been approved
for your vehicle by smart.
Proper use of the seat belts
Pay attention to the safety notes about the
seat belt (Ypage 31).
All vehicle occupants must fasten the seat
belt correctly before setting off. Make sure
that all occupants are wearing their seat
belts correctly for the entire journey.
When fastening the seat belt, make sure that:
RThe seat belt tongue is inserted into the
belt buckle that belongs to the seat.
RThe seat belt is tightened across your body.
Avoid wearing bulky clothing, e.g. a winter coat.
RThe seat belt is not twisted.
Only then can the forces produced in the
event of an accident be evenly distributed
across the belt.
RThe shoulder section of the belt must always
be routed across the center of the shoulder.
The shoulder section of the belt should not come into contact with your neck and must
not be routed under the arm.
RThe lap belt must be taut and as low as pos-
sible over your lap.
The lap belt must always pass across your
hip joints and never across your stomach or
abdomen. Pregnant women must take par-
ticular care. If necessary, the lap belt canbe pushed down across the hip joints and
pulled tight using the shoulder section.
RThe seat belt is not routed over sharp,
pointed or fragile objects.
If these items are on or in your clothing,
e.g. eyeglasses, pens, keys, etc., stow theseitems in a more suitable location.
ROnly one person should use each seat belt at
any one time.
On no account should babies or children
travel sitting on the lap of another vehicle occupant. During an accident, they could be
crushed between the occupant and seat belt.
RObjects are not secured with a seat belt if
the seat belt is being used by one of the
vehicle’s occupants.
32Occupant safety
>> Safety.

Also make sure that there are no objects,
e.g. cushions, between the occupant and the
seat.
Seat belts are solely intended for the pro-
tection and restraint of the vehicle occu-
pants. To secure objects, luggage or loads,
always observe the "Loading guidelines"
(
Ypage 142).
Fastening seat belts
Observe the safety notes on the seat belt
(Ypage 31) and the notes on correct use of seat
belts (Ypage 32).
For easy fastening, the seat belt passes
through a belt loop on the side of the seat.
Basic illustration
XAdjust the seat (Ypage 61).
The seat backrest must be in an almost ver-
tical position.
XPull the seat belt smoothly from belt outlet
0087 and engage belt tongue 0044into belt
buckle 0043.
XIf necessary, pull upwards on the shoulder
section of the seat belt to tighten the belt
across your body.
In order to attach the child restraint system
securely in the vehicle, the seat belt on the
front-passenger seat is equipped with a spe- cial seat belt retractor. Further information
on the "Special seat belt retractor"
(
Ypage 43).
Releasing seat belts
!Make sure that the seat belt is fully rolled
up. Otherwise, the seat belt or belt tongue
will be trapped in the door or in the seat
mechanism. This could damage the door, the
door trim panel and the seat belt. Damaged seat belts can no longer fulfill their pro-
tective function and must be replaced.
Visit a qualified specialist workshop.
XPress the release button in the belt buckle,
hold the belt tongue firmly and guide the
belt back.
Belt warning for the driver and front
passenger
The 0076 seat belt warning lamp in the
instrument cluster is a reminder that all
vehicle occupants must wear their seat belts.
It may light up continuously or flash. In addi-
tion, there may be a warning tone.
Regardless of whether the driver's seat belt
has already been fastened, the 0076seat belt
warning lamp lights up for six seconds each
time the engine is started. If the driver's or
front-passenger seat belt has not been fas-
tened, the 0076seat belt warning lamp starts
to light up continuously after these
six seconds. As soon as the driver and front
passenger fasten their seat belts, the 0076
seat belt warning lamp goes out.
If the driver's seat belt is not fastened after
the engine is started, an additional warning
tone will sound. The warning tone switches off
after six seconds or once the driver's seat
belt is fastened.
If the vehicle speed exceeds 12 mph (20 km/h)
and the driver's or front-passenger seat belt
is not fastened, a warning tone sounds again.
The warning tone sounds with increasing
intensity for a maximum of 120 seconds or
until the driver or front passenger have fas-
tened their seat belts.
If the driver or front passenger unfasten
their seat belts during the journey, the seat
belt warning is activated again.

Air bags
Introduction
The air bag installation point is identified
by the label AIR BAG.
An air bag supplements a correctly fastened
seat belt. However, it is not intended as a
substitute for the seat belt. Air bags provide
additional protection in the event of an acci- dent.
Not all air bags are deployed in an accident.
The various air bag systems work independ-
ently of each other (
Ypage 40).
There is, however, no system available today
that can completely rule out injury or death.
It is also not possible to rule out a risk of
injury caused by an air bag due to the high
speed at which the air bag must be deployed.
Important safety notes
GWARNING
If you do not sit in the correct seat posi-
tion, the air bag cannot protect as intended
and could even cause additional injury
when deployed. This poses an increased
risk of injury or even fatal injury.
To avoid hazardous situations, always make
sure that all of the vehicle's occupants:
Rhave fastened their seat belts correctly,
including pregnant women
Rare sitting correctly and maintain the
greatest possible distance to the air
bags
Rfollow the following instructions
Always make sure that there are no objects
between the air bag and the vehicle's occu- pants.
RAdjust the seats properly before beginning
your journey. Always make sure that the seatis in an almost upright position.
RMove the driver's and front-passenger
seats as far back as possible. The driver's
seat position must allow the vehicle to be
driven safely.
ROnly hold the steering wheel on the outside.This allows the air bag to be fully deployed.
RAlways lean against the backrest while
driving. Do not lean forwards or lean
against the door or side window. You may
otherwise be in the deployment area of the
air bags.
RAlways keep your feet in the footwell in
front of the seat. Do not put your feet on the
dashboard, for example. Your feet may oth-
erwise be in the deployment area of the air
bag.
RFor this reason, always secure persons lessthan 5 ft (1.50 m) tall in suitable restraint
systems. Up to this height, the seat belt
cannot be worn correctly.
If a child is traveling in your vehicle, also
observe the following notes:
RAlways secure children under twelve years
of age and less than 5 ft (1.50 m) tall in
suitable child restraint systems.
ROnly secure a child in a rearward-facing
child restraint system on the front-
passenger seat when the front-passenger
front air bag is deactivated. If the
PASSENGER AIR BAG OFF indicator lamp is
permanently lit, the front-passenger front air bag is deactivated (
Ypage 30).
RAlways observe the instructions and safety
notes on the "Occupant Classification Sys-
tem (OCS)" (
Ypage 36) and on "Children in
the vehicle" (Ypage 42) in addition to the
child restraint system manufacturer's
installation and operating instructions.
Objects in the vehicle interior may prevent
an air bag from functioning correctly. Before
starting your journey and to avoid risks
resulting from the speed of the air bag as it
deploys, make sure that:
Rthere are no people, animals or objects
between the vehicle occupants and an air
bag.
Rthere are no objects between the seat, door and B-pillar.
Rno hard objects, e.g. coat hangers, hang on
the grab handles or coat hooks.
Rno accessories, such as cup holders, are
attached to the vehicle within the deploy-
ment area of an air bag, e.g. to doors or side
windows.
Rno heavy, sharp-edged or fragile objects
are in the pockets of your clothing. Store
such objects in a suitable place.
34Occupant safety
>> Safety.

GWARNING
If you modify the air bag cover or affix
objects such as stickers to it, the air bag
can no longer function correctly. There is
an increased risk of injury.
Never modify an air bag cover or affix
objects to it.
GWARNING
Sensors to control the air bags are located
in the doors. Modifications or work not
performed correctly to the doors or door
paneling, as well as damaged doors, can
lead to the function of the sensors being
impaired. The air bags might therefore not
function properly anymore. Consequently,
the air bags cannot protect vehicle occu-
pants as they are designed to do. There is an increased risk of injury.
Never modify the doors or parts of the
doors. Always have work on the doors or door
paneling carried out at a qualified spe-
cialist workshop.
Front air bags
Driver's air bag 0043deploys in front of the
steering wheel. Front-passenger front air
bag 0044deploys in front of and above the glove
box.
When deployed, the front air bags offer addi-
tional head and thorax protection for the
occupants in the driver's and front-
passenger seats.
The PASSENGER AIR BAG OFF and PASSENGER
AIR BAG ON indicator lamps inform you about the status of the front-passenger air bag
(
Ypage 30).
The front-passenger front air bag will only
deploy if:
Rthe system, based on the OCS weight sensor
readings, detects that the front-passenger
seat is occupied (
Ypage 36). The
PASSENGER AIR BAG ON indicator lamp is
lit (
Ypage 37)
Rthe restraint system control unit predicts a high accident severity
Knee bags
Driver's knee bag 0043deploys under the steer-
ing column and front-passenger knee bag 0044
under the glove box. The driver's and front-
passenger knee bags are triggered together
with the front air bags.
The driver's and front-passenger knee bags
offer additional thigh, knee and lower leg
protection for the occupants in the front
seats.
Thorax/pelvis air bags
GWARNING
Unsuitable seat covers could restrict or
even prevent the deployment of the air bags integrated into the seats. Consequently,
the air bags cannot protect vehicle occu-
pants as they are designed to do. In addi-
tion, the operation of the occupant classi-
fication system (OCS) could be adversely
affected. This poses an increased risk of
injury or even fatal injury.
You should only use seat covers that have
been approved for the corresponding seats
by smart.
Occupant safety35

Z

Thorax/pelvis air bags0043deploy next to the
outer bolster of the seat backrest.
When deployed, the thorax/pelvis air bags
offer additional thorax and pelvis protec-
tion.
In the event of a side impact, the thorax/
pelvis air bag is deployed on the side on
which the impact occurs.
The thorax/pelvis air bag on the front-
passenger side deploys under the following
conditions:
Rthe OCS system detects that the front-
passenger seat is occupied or
Rthe belt tongue is engaged in the belt
buckle of the front-passenger seat
If the belt tongue is engaged in the belt
buckle, the thorax/pelvis air bag on the
front-passenger side deploys if an appro-
priate accident situation occurs. In this
case, deployment is independent of whether
the front-passenger seat is occupied or not.
Window curtain air bags
Window curtain air bags 0043are integrated
into the side of the roof frame above the
doors. When deployed, the window curtain air bag
enhances the level of protection for the head.
However, it does not protect the chest or arms.
In the event of a side impact, the window cur-
tain air bag is deployed on the side on which
the impact occurs.
If the system determines that they can offer
additional protection to that provided by the
seat belt, a window curtain air bag may be
deployed in other accident situations
(
Ypage 40).
Occupant Classification System (OCS)
Introduction
The Occupant Classification System (OCS)
categorizes the person in the front-
passenger seat. Depending on that result, the
front-passenger front air bag and front-
passenger knee bag are either enabled or
deactivated.
The system does not deactivate:
Rthe thorax/pelvis air bag
Rthe window curtain air bag
Rthe Emergency Tensioning Devices
Prerequisites
To be classified correctly, the front
passenger must sit:
Rwith the seat belt fastened correctly
Rin an almost upright position with their
back against the seat backrest
Rwith their feet resting on the floor, if pos-
sible
If the front passenger does not observe these
conditions, OCS may produce a false classi-
fication, e.g. because the front passenger:
Rtransfers their weight by supporting them-
selves on a vehicle armrest
Rsits in such a way that their weight is
raised from the seat cushion
If you install a child restraint system on the
front-passenger seat, be sure to observe the
correct positioning of the child restraint
system. Never place objects under or behind
the child restraint system, e.g. cushions. The entire base of the child restraint system must
always rest on the seat cushion of the front-
passenger seat. The backrest of the forward-
36Occupant safety
>> Safety.

facing child restraint system must lie as flat
as possible against the backrest of the front-
passenger seat.
The child restraint system must not touch the
roof. Adjust the backrest angle accordingly.
Only then can OCS be guaranteed to function
correctly. Always observe the child restraint
system manufacturer's installation instruc-
tions.

The indicator lamps indicate whether the
front-passenger front air bag is activated or
deactivated.
XTurn the key to position 1or 2in the igni-
tion lock.
The system carries out a self-diagnosis
test.
The PASSENGER AIR BAG OFF and PASSENGER
AIR BAG ON indicator lamps must light up
simultaneously for about six seconds.
The indicator lamps then display the status of
the front-passenger front air bag:
RPASSENGER AIRBAG ON lights up: the front-
passenger front airbag is enabled. If, in
the case of an accident, all deployment cri-
teria are met, the front-passenger front
air bag is deployed.
RPASSENGER AIRBAG OFF lights up: the front-
passenger front airbag is disabled. It will then not be deployed in the event of an
accident.
Always observe the PASSENGER AIR BAG ON and
PASSENGER AIR BAG OFF indicator lamps when
the front-passenger seat is occupied. Make
sure that the status of the front-passenger front air bag is correct before and during a
journey.
GWARNING
If the PASSENGER AIR BAG OFF indicator
lamp is lit, the front-passenger front air
bag is disabled. It will not be deployed in
the event of an accident and cannot perform
its intended protective function. A person
in the front-passenger seat could then, for
example, come into contact with the vehi-
cle's interior, especially if the person is
sitting too close to the dashboard. This
poses an increased risk of injury or even
fatal injury.
When the front-passenger seat is occupied, always ensure that:
Rthe classification of the person in the
front-passenger seat is correct and the
front-passenger front air bag is enabledor disabled in accordance with the per-
son in the front-passenger seat
Rthe front-passenger seat has been movedback as far back as possible.
Rthe person is seated correctly.
Make sure, both before and during the jour-
ney, that the status of the front-passenger
front air bag is correct.
GWARNING
If you secure a child in a rearward-facing
child restraint system on the front-
passenger seat and the PASSENGER AIR BAG
ON indicator lamp is lit up, the front-
passenger front air bag may deploy in an
accident. The child could be struck by the
air bag. This poses an increased risk of
injury or even fatal injury.
Make sure that the front-passenger front
air bag has been disabled. The PASSENGER
AIR BAG OFF indicator lamp must be lit.
If the PASSENGER AIR BAG OFF indicator lamp
remains off and/or the PASSENGER AIR BAG ON
indicator lamp is lit, do not fit a rearward-
facing child restraint system to the front-
passenger seat. For more information, see
Occupant safety37
>> Safety.
Z

"Problems with the Occupant Classification
System (OCS)" (Ypage 40).
GWARNING
If you secure a child in a forward-facing
child restraint system on the front-
passenger seat and you position the front-
passenger seat too close to the dashboard,
in the event of an accident, the child could:
Rcome into contact with the vehicle's
interior if the PASSENGER AIR BAG OFF
indicator lamp is lit, for example
Rbe struck by the air bag if the PASSENGER
AIR BAG ON is lit up
This poses an increased risk of injury or
even fatal injury.
Move the front-passenger seat as far back
as possible. Always make sure that the
shoulder belt strap is correctly routed
from the vehicle belt guide to the shoulder
belt guide on the child restraint system.
The shoulder belt strap must be routed for-
wards and downwards from the belt guide.
Always observe the child restraint system
manufacturer's installation instructions.
If OCS detects that:
Rthe front-passenger seat is not occupied,
the PASSENGER AIR BAG OFF indicator lamp
lights up continuously after the system's
self-diagnosis test. This indicates that
the front-passenger front air bag is deac-
tivated.
Rthe front-passenger seat is occupied by a
child aged up to twelve months in a stand-
ard child restraint system, the PASSENGER
AIR BAG OFF indicator lamp lights up con-
tinuously after the system's self-diagnosis
test. This indicates that the front-
passenger front air bag is deactivated.
In the case of a twelve-month-old child in a
standard child restraint system, the
PASSENGER AIR BAG ON indicator lamp may
light up continuously after the system's
self-diagnosis test. This indicates that
the front-passenger front air bag is acti-
vated. Categorization is dependent on the
type of child restraint system and the stat-
ure of the child, for example. Make sure
that the prerequisites for correct catego- rizat
ion have been met. If the PASSENGER
AIR BAG ON indicator lamp remains lit, do
not install a child restraint system on the
front-passenger seat.
Rthe front-passenger seat is occupied by a
person of smaller stature (e.g. a teenager
or a small adult), either the PASSENGER AIR
BAG ON or PASSENGER AIR BAG OFF indicator
lamp lights up continuously after the sys-
tem's self-diagnosis test depending on the categorization.
-If the PASSENGER AIR BAG ON indicator
lamp is lit, position the front-
passenger seat as far back as possible.
-If the PASSENGER AIR BAG OFF indicator
lamp lights up, a person of smaller stat-
ure should not sit on the front-passenger
seat.
Rthe front-passenger seat is occupied by an
adult or a person of an appropriate size,
the PASSENGER AIR BAG ON indicator lamp
lights up continuously after the system's
self-diagnosis test. This indicates that
the front-passenger front air bag is acti-
vated.
If children are traveling in the vehicle, be
sure to observe the notes on "Children in the
vehicle" (
Ypage 42).
If the OCS is malfunctioning, both the red
0075 restraint system warning lamp in the
instrument cluster and the PASSENGER AIR
BAG OFF indicator lamp light up simultane-
ously. In this case, the front-passenger air
bag is deactivated and does not deploy during
an accident. Have the system checked by
qualified technicians as soon as possible.
Consult a smart center. Only have the front-
passenger seat repaired at a smart center.
If the front-passenger seat, the seat cover or
the seat cushion are damaged, have the nec-
essary repair work carried out at a smart cen-
ter.
For safety reasons, smart recommends that you only use seat accessories which have been
approved by smart.
If the driver's air bag deploys , this does not
mean that the front-passenger front air bag
will also deploy. The Occupant Classifica-
tion System (OCS) categorizes the occupant on
the front-passenger seat. Depending on the
result, the front-passenger air bag is acti-
vated or deactivated.
