collision. If you slide under it, the belt
would apply force at the abdomen or neck,
causing
serious or even fatal injuries. The
seat backrest and seat belt provide the best
restraint when the wearer is in a position
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
correctly restrained with a separate seat
belt.

Never use a seat belt for more than one
person at a time. G
WARNING
Seat belts of a vehicle involved in an
accident must be inspected by smart. Only
then is it possible to determine whether
the seat belts were damaged or stressed in
the accident. 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
activation 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 smart
center. G
WARNING
USE SEAT BELTS PROPERLY
R Seat belts can only work when used
properly. 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 32
Occupant safety
>> Safety.

should be positioned as low as possible
on the hips to avoid any possible
pressure on the abdomen.
R Never place your feet on the instrument
panel, dashboard or on the seat. Always
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
manufacturer’s instructions. Emergency Tensioning Devices (ETDs)
and seat belt force limiters
The seat belts are equipped with
Emergency 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
exceeding the system deployment
threshold
R if the restraint systems are operational
and functioning correctly
R in collisions with high vehicle
deceleration/acceleration in the
longitudinal direction, e.g. a head-on
collision
R on passenger side when the seat is
occupied 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
during a crash.
When the emergency tensioning device is
triggered, the SRS indicator lamp 6 in
the instrument cluster illuminates, see
“SRS indicator lamp” ( Y page 166). G
WARNING
Once they have been triggered, Emergency
Tensioning
Devices will no longer function
properly and must be replaced. smart
recommends that you visit a qualified
workshop to have this done. In particular,
work relevant to safety or on safety-related
systems must be carried out at a qualified
specialist workshop.
Comply with safety regulations when
disposing of Emergency Tensioning
Devices. These regulations are available at
any smart center.
The belt force limiter is designed to
operate in unison with the front air bag,
which absorbs a portion of the seat belt’s
decelerating forces, distributing the load
over a larger area.
In the event of a head-on or rear-end
collision, the emergency tensioning
device is activated if the vehicle is
decelerated or accelerated sufficiently in
the longitudinal direction at the start of
impact with the ignition switched on. Air bags
Air bags can reduce the severity of
injuries in serious collisions, e.g. in a
head-on collision or a side impact. G
WARNING
Air bags are designed to reduce the
potential 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
injuries. 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 Occupant safety

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
Occupant safety

before seating any child on the passenger
seat.
More information can be found in the
“Practical hints” section ( Y page 173).G
WARNING
Never place anything between seat cushion
and child seat (e.g. pillow), since it
reduces the effectiveness of the Occupant
Classification System. The bottom of the
child seat must make full contact with the
passenger seat cushion. An incorrectly
mounted

child seat could cause injuries to the child in case of an accident, instead of
increasing protection for the child.
Follow the manufacturer’s instructions for
installation of child seats.
Children in the vehicle
If an infant or child is traveling with you
in the vehicle:
X Secure the child using an infant or child
restraint

appropriate to the age and size
of the child.
X Make sure the infant or child is properly

children larger than the typical
12‑month‑old child, the passenger front
air bag may or may not be activated. G
WARNING
Infants and small children should never
share a seat belt with another occupant.
During an accident, they could be crushed
between the occupant and seat belt.
A child’s risk of serious or fatal injuries
is significantly increased if the child
restraints are not properly secured in the
vehicle and/or the child is not properly
secured in the child restraint.
Children too big for a toddler restraint
must

ride in a seat using regular seat belt.
Position shoulder belt across chest and
shoulder, not face or neck. A booster seat
may be necessary to achieve proper seat
belt positioning for children over 41 lbs
until they reach a height where a lap-
shoulder belt fits properly without a
booster.
When the child restraint is not in use,
remove it from the vehicle or secure it with
the seat belt to prevent the child restraint
from becoming a projectile in the event of
an accident.
Do not leave children unattended in the
vehicle, even if the children are secured in
a child restraint system. Unsupervised
children in a child restraint system may
use vehicle equipment and may cause an
accident and/or serious personal injury.
If you are using a rear-facing child
restraint system on the passenger seat, you
must verify that the passenger front air bag
is deactivated. When the passenger front
air bag is deactivated, the
4 0 indicator lamp is

Never ride in a moving vehicle with the seat
backrest in an excessively reclined
position as this can be dangerous. You
could slide under the seat belt in a
collision. If you slide under the seat belt,
it could apply force at the abdomen or neck,
potentially causing serious or fatal
injuries. The seat backrest and seat belts
provide the best restraint when the wearer
is in a position that is as upright as
possible and seat belts are properly
positioned on the body.
Your seat must be adjusted so that you can
correctly fasten your seat belt.
Observe the following points:
R Adjust the seat backrest until your arms
are slightly angled when holding the
steering wheel.
R Adjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely. The
position should be as far back as
possible with the driver still able to
operate the controls properly.
R Never place hands under the seat or near
any moving parts while a seat is being
adjusted.
Failure to do so could result in an accident
and/or serious personal injury.
