2016 SMART FORTWO warning

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.

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.
How the occupant classification system
(OCS) operates
0043PASSENGER AIR BAG OFF indicator lamp
0044PASSENGER AIR BAG ON indicator lamp
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.

System self-test
GDANGER
If both the PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps do
not light up during the system self-test, the
system is malfunctioning. The front-
passenger front air bag might be triggered
unintentionally or might not be triggered
at all in the event of an accident with high
deceleration. This poses an increased risk
of injury or even fatal injury.
In this case the front-passenger seat may
not be used. Do not install a child restraint
system on the front-passenger seat. Have
the Occupant Classification System (OCS)
checked and repaired immediately at a
qualified specialist workshop.
GDANGER
If the PASSENGER AIR BAG OFF indicator
lamp remains lit after the system self-test, the front-passenger front air bag is disa-
bled. It will not be deployed in the event of
an accident. In this case, the front-
passenger front air bag cannot perform its
intended protective function, e.g. when a
person is seated in the front-passenger
seat.
That person could, for example, come into
contact with the vehicle's interior, espe-
cially 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 person is seated properly with a cor-
rectly fastened seatbelt
Rthe front-passenger seat has been movedback as far back as possible
If the PASSENGER AIR BAG OFF indicator
lamp remains lit when it should not, the
front-passenger seat may not be used. Do
not install a child restraint system on the
front-passenger seat. Have the Occupant
Classification System (OCS) checked and
repaired immediately at a qualified spe-
cialist workshop.
GWARNING
Objects between the seat surface and the
child restraint system could affect OCS
operation. This could result in the front-
passenger air bag not functioning as
intended during an accident. This poses an increased risk of injury or even fatal
injury.
Do not place any objects between the seat
surface and the child restraint system. 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-facing child restraint system
must, as far as possible, be resting on the
backrest of the front-passenger seat.
Always comply with the child restraint sys-
tem manufacturer's installation instruc-
tions.
After the system self-test, the PASSENGER AIR
BAG OFF or PASSENGER AIR BAG ON indicator
lamp displays the status of the front-
passenger front air bag (
Ypage 37).

Deployment of belt tensioners and air
bags
Important safety notes
GWARNING
The air bag parts are hot after an air bag
has been deployed. There is a risk of
injury.
Do not touch the air bag parts. Have a
deployed air bag replaced at a qualified
specialist workshop as soon as possible.
GWARNING
A deployed air bag no longer offers any
protection and cannot provide the intended
protection in an accident. There is an
increased risk of injury.
Have the vehicle towed to a qualified spe-
cialist workshop in order to have a
deployed air bag replaced.
For your own safety and that of your front
passenger, it is important that you have
deployed air bags replaced and faulty air
bags repaired. This will help to make sure the
air bags continue to perform their protective
function for the vehicle occupants in the
event of a crash.
40Occupant safety
>> Safety.

GWARNING
Pyrotechnic Emergency Tensioning Devices
that have been deployed are no longer
operational and are unable to perform
their intended protective function. This
poses an increased risk of injury or even
fatal injury.
Therefore, have pyrotechnic Emergency
Tensioning Devices which have been trig-
gered immediately replaced at a qualified
specialist workshop.
If Emergency Tensioning Devices are trig-
gered or air bags are deployed, you will hear
a bang, and a small amount of powder may also
be released. The 0075restraint system warn-
ing lamp lights up.
Only in rare cases will the bang affect your
hearing. The powder that is released gener-
ally does not constitute a health hazard, but it may cause short-term breathing difficulties
in people with asthma or other respiratory
problems. Provided it is safe to do so, you
should leave the vehicle immediately or open
the window in order to prevent breathing dif-
ficulties.
Air bags and pyrotechnic Emergency Tension-
ing Devices (ETDs) contain perchlorate mate-
rial, which may require special handling and
regard for the environment. National guide-
lines must be observed during disposal. In
California, see www.dtsc.ca.gov/
HazardousWaste/Perchlorate/index.cfm .
Method of operation
During the first stage of a collision, the
restraint system control unit evaluates
important physical data relating to vehicle
deceleration or acceleration, such as:
Rduration
Rdirection
Rintensity
Based on the evaluation of this data, the
restraint system control unit triggers the
Emergency Tensioning Devices during a fron- tal or rear collision. An Emergency Tensioning Device can only be
triggered, if:
Rthe ignition is switched on
Rthe components of the restraint system are
operational. You can find further informa-
tion under: "Restraint system warning
lamp" (
Ypage 30)
Rthe belt tongue has engaged in the belt
buckle of the respective seat
If the restraint system control unit detects a
more severe accident, further components of
the restraint system are activated independ- ently of each other in certain frontal colli-
sion situations:
RFront air bags as well as driver's and front-
passenger knee bags
RWindow curtain air bag, if the system
determines that deployment can offer
additional protection to that provided by
the seat belt
The front-passenger front air bag is activa-
ted or deactivated depending on the person on
the front-passenger seat. The front-
passenger front air bag can only deploy in an
accident if the PASSENGER AIR BAG ON indi-
cator lamp is lit. Observe the information on
the PASSENGER AIR BAG indicator lamps
(
Ypage 30).
Your vehicle has two-stage front air bags.
During the first deployment stage, the front
air bag is filled with propellant gas to
reduce the risk of injuries. The front air bag
is fully deployed with the maximum amount of
propellant gas if a second deployment
threshold is reached within a few millisec-
onds.
The activation threshold of the Emergency
Tensioning Devices and the air bag are
determined by evaluating the rate of vehicle
deceleration or acceleration which occurs at
various points in the vehicle. This process is
pre-emptive in nature. Deployment should
take place in good time at the start of the
collision.
The rate of vehicle deceleration or acceler-
ation and the direction of the force are
essentially determined by:
Rthe distribution of forces during the col-
lision
Rthe collision angle
