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 cor- rectly restrained with a separate seat belt.Never use a seat belt for more than one per-
son at a time. G
WARNING
Seat belts of a vehicle involved in an acci- dent must be inspected by smart. Only then
is it possible to determine whether the seat belts were damaged or stressed in the acci-dent. 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 activa-
tion 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 elec-
tric drive smart center. G
WARNING
USE SEAT BELTS PROPERLY R Seat belts can only work when used prop-
erly. 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 shoul-
der. Doing so may cause your body to movetoo 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 abdo-
men, which could severely injure inter-
nal 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
should be positioned as low as possible
on the hips to avoid any possible pres-
sure 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 32

When the 40indicator lamp is
illuminated, the passenger front air bag is
deactivated.
When the 40indicator lamp is
out and the passenger seat is occupied by an adult or someone larger than a small indi-
vidual, the passenger front air bag is acti-
vated.
When the OCS senses that the passenger seat occupant is classified as an adult or some- one larger than a small individual, the
40indicator lamp will illu-
minate 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 40indicator lamp is
illuminated, the passenger front air bag is
deactivated and will not be deployed.
If the 40indicator lamp is not
illuminated, the passenger front air bag is
activated and will be deployed

WARNING
Children 12 years old and under must be
seated and properly secured in an appro-
priate infant or child restraint recommen- ded for the size and weight of the child.
The infant or child restraint must be prop-
erly 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 appropri-
ate 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 circum-
stances, even with the air bag technology
installed in your vehicle.
R If you install a rear-facing child
restraint on the passenger seat, make
sure the 40indicator lamp
is illuminated, indicating that the
passenger front air bag is deactivated.
Should the 40indicator
lamp not illuminate or go out while the
restraint is installed, please check
installation.
Periodically check the 40
indicator lamp while driving to make
sure the 40indicator lamp
is illuminated.
If the 40indicator lamp
goes out or remains out, do not transport a child on the passenger seat until the
system has been repaired.
A child in a rear-facing child restraint
on the passenger seat may be seriously
injured or even killed if the passenger
front air bag inflates.
R If you place a child in a forward-facing
child restraint on the passenger seat,
move the seat as far back as possible, use
the proper child restraint recommended
for the age, size and weight of the child 40

by the seat manufacturer, and secure
child restraint with the vehicle’s seat
belt according to the child seat manu-
facturer’s instructions. For children
larger than the typical 12‑month‑old
child, the passenger front air bag may or may not be activated.
i Deployment of the driver front air bag
does not mean that the passenger front
air bag also should have deployed.
The Occupant Classification System may
have determined R that the seat was empty or occupied by the
weight up to or less than that of a typical 12‑month‑old child seated in a standard
child restraint — both instances where
the system suppresses deployment of the
passenger front air bag even though the
impact met the criteria and was of suf-
ficient severity to deploy the driver
front air bag
R that the seat was occupied by a small
individual (such as a young teenager or a
small adult) or a child weighing more
than the weight of a typical 12‑month‑old
child in a standard child restraint —
instances where the system may suppress deployment of the passenger front air
bag even though the impact met the cri-
teria and was of sufficient severity to
deploy the driver front air bag
Passenger front air bag off indicator
lamp The indicator lamp is located on the over-
head control panel. Passenger front air bag off indicator
lamp
:illuminates when the passenger
front air bag is deactivated. G
WARNING
When the SRS indicator lamp 6and the
40indicator lamp are lit at
the same time, there is a malfunction in the Occupant Classification System.
In order to ensure proper operation of the
air bag system and OCS:
R Have the system checked as soon as pos-
sible by qualified technicians. Contact
an authorized electric drive smart cen-
ter.
R Sit properly belted in a position that is
as upright as possible with your back
against the seat backrest.
R Do not lean on the armrests or lift your-
self from the seat by using the handle
over the door as this may cause the OCS to
be unable to correctly approximate the
occupant weight category.
R Only have the seat repaired or replaced
by an authorized electric drive smart
center.
R Read and observe all warnings in this
chapter.
Self-test Occupant Classification Sys-
tem After turning the key in the starter switch
to position

properly sitting on the passenger seat and
the system senses the occupant as being an
adult, the 40indicator lamp
will illuminate and go out after approx-
imately 4 seconds.
If the seat is not occupied and the system
senses the passenger seat as being empty,
the 40indicator lamp will
illuminate and not go out. G
WARNING
If the 40indicator lamp does
not illuminate immediately after switch-
ing on the drive system, the system is not
functioning. You must contact an author-
ized electric drive smart center before
seating any child on the passenger seat.
More information can be found in the
“Practical hints” section (Y page 175).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
secured at all times while the vehicle is in motion. G
WARNING
Do not leave children unattended in the
vehicle, even if they are secured in a child restraint system. The children could
R injure themselves on parts of the vehicle
R be seriously or fatally injured through
excessive exposure to extreme heat or
cold
Do not expose the child restraint system to
direct sunlight. The child restraint sys-
tem’s metal parts, for example, could
become very hot, and the child could be
burned on these parts.
If children open a door, they could
R injure other persons
R get out of the vehicle and injure them-
selves or be injured by following traffic
Do not carry heavy or hard objects in the
passenger compartment unless they are
firmly secured in place.
For more information, please refer to the
“Loading and storing section”.
Unsecured or improperly positioned cargo
increases a child’s risk of injury in the
event of
R strong braking maneuvers
R sudden changes of direction
R an accident
Infant and child restraint system We recommend all infants and children be
properly restrained at all times while the
vehicle is in operation.
The passenger lap-shoulder belt has a spe-
cial seat belt retractor for secure fasten-
ing of child restraints.
To fasten a child restraint, follow all
mounting instructions provided by the
child restraint manufacturer. Then pull the
shoulder seat belt out completely and let it
retract. During seat belt retraction, a
ratcheting sound can be heard to indicate
that the special seat belt retractor is acti- 42

vated. The seat belt is now locked. Push
down on child restraint to take up any
slack.
To deactivate, release seat belt buckle and
let seat belt retract completely. To deac-
tivate the special seat belt retractor for
the passenger seat, the passenger seat must be in the most backward position. The seatbelt can again be used in the usual manner. G
WARNING
Never release the seat belt buckle while the vehicle is in motion, since the special seatbelt retractor will be deactivated.
The use of infant or child restraints is
required by law in all 50 states, the Dis-
trict of Columbia, the U.S. territories, and
all Canadian provinces and territories.
Infants and small children should be seated in an appropriate infant or child restraint
system properly secured in accordance
with the manufacturer’s instructions for
the child restraint, that complies with U.S. Federal Motor Vehicle Safety Standards 213and 225 and Canadian Motor Vehicle Safety
Standards 213, 213.1 and 213.2.
A statement by the child restraint manu-
facturer of compliance with these stand-
ards can be found on the instruction label
on the restraint and in the instruction
manual provided with the restraint.
When using any infant restraint, toddler
restraint, or booster seat be sure to care-
fully read and follow all manufacturer’s
instructions for installation and use.
Please read and observe warning labels
affixed to the inside of the vehicle and to
infant or child restraints. G
WARNING
Children 12 years old and under must be
seated and properly secured in an appro-
priately sized infant restraint, toddler
restraint, or booster seat recommended for the size and weight of the child. The infant or child restraint must be prop-
erly secured with the vehicle’s seat belt
fully in accordance with the child seat
manufacturer’s instructions.
Occupants, especially children, should
never place their bodies or lean their
heads in the area of the door where the
head-thorax air bags (cabriolet), window
curtain air bags (coupé) and thorax-pelvis
air bags (coupé) inflates. This could result in serious injuries or death should the
head-thorax air bags (cabriolet), window
curtain air bags (coupé) and thorax-pelvis
air bags (coupé) be triggered. Always sit as
upright as possible, properly use the seat
belt and use an appropriately sized infant
restraint, toddler restraint, or booster
seat recommended for the size and weight of
the child.
Children can be killed or seriously injured by an inflating air bag. Note the following
important information when circumstances
require you to place a child in the
passenger seat:
R Your vehicle is equipped with air bag
technology designed to turn off the
passenger front air bag in your vehicle
when the Occupant Classification System
senses the weight of a typical
12‑month‑old child or less along with the
weight of an appropriate child restraint
on the passenger seat.
R A child in a rear-facing child restraint
on the passenger seat may be seriously
injured or even killed if the passenger
front air bag inflates in a collision.
R If you install a rear-facing child
restraint on the passenger seat, make
sure the 40indicator lamp
is illuminated, indicating that the
passenger front air bag is deactivated.
Should the 40indicator
lamp not illuminate or go out while the
restraint is installed, please check
installation. Periodically check the
40indicator lamp while Occupant safety

driving to make sure the
40
indicator lamp is illuminated. If the
40indicator lamp goes out
or remains out, do not transport a child
on the passenger seat until the system has been repaired. A child in a rear-facing
child restraint on the passenger seat may
be seriously injured or even killed if the passenger front air bag inflates.
R If you place a child in a forward-facing
child restraint on the passenger seat,
move the seat as far back as possible, use a proper child restraint recommended
for the age, size and weight of the child,
and secure child restraint with the vehi- cle’s seat belt according to the child seat
manufacturer’s instructions. For chil-
dren 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 boos- ter.
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 40
indicator lamp is illuminated (Y page 41).
Top tether
Top tether permits an additional connec-
tion between a child restraint system and
the passenger seat. Proper usage of the top
tether, in accordance with instructions
provided by the child restraint manufac-
turer, can further reduce the risk of inju-
ries.
The top tether anchorage is located on the
floor of the cargo compartment. The top
tether guide for the top tether strap is
located above, on the head restraint. 44
