temporary breathing difficulty for people
with asthma or other breathing trouble. To
avoid this, you may wish to get out of the
vehicle as soon as it is safe to do so. If you
have any breathing difficulty but cannot
get out of the vehicle after the air bag
inflates, then get fresh air by opening a
window or door. G
WARNING
To reduce the risk of injury when the front
air bags inflate, it is very important for
the driver and passenger to always be in a
properly seated position and to wear their
respective seat belt.
For maximum protection in the event of a
collision always be in normal seated
position with your back against the
backrest. Fasten your seat belt and ensure
it is properly positioned on your body.
Since the air bag inflates with
considerable speed and force, a proper
seating and hands on steering wheel
position will help to keep you at a safe
distance from the air bag.
Occupants who are unbelted, out of position
or too close to the air bag can be seriously
injured or killed by an air bag as it
inflates extremely quickly and with great
force:
R Sit properly belted in a position that is
as upright as possible with your back
against the seat backrest.
R Adjust the driver’s seat as far as possible
rearward, still permitting proper
operation of vehicle controls. The
distance from the center of the driver’s
breastbone to the center of the air bag
cover on the steering wheel must be at
least 10 inches (25 cm) or more. You should
be able to accomplish this by
adjustments to the seat. If you have any
problems, please contact an authorized
electric drive smart center.
R Do not lean your head or chest close to the
steering wheel or dashboard. R
Keep hand son the outside of the steering
wheel rim. Placing hands and arms inside
the rim can increase the risk and
potential severity of hand/arm injury
when the driver’s front air bag inflates.
R Adjust the passenger seat as far as
possible rearward from the dashboard
when the seat is occupied.
R Occupants, especially children, should
never place their bodies or lean their
heads in the area of the door where the
head-thorax air bag (cabriolet) or
thorax-pelvis side air bag (coupé)
inflates. This could result in serious
injuries or death should the head-thorax
air bag (cabriolet) or thorax-pelvis side
air bag (coupé) be deployed. Always sit
as upright as possible, wear the seat belt
properly and use an appropriately sized
infant restraint, toddler restraint, or
booster seat recommended for the size
and weight of the child.
Failure to follow these instructions can
result in severe injuries to you or other
occupants.
If you sell your vehicle, it is important that
you make the buyer aware of this safety
information. Be sure to give the buyer this
Operator’s Manual.
i Air bags are designed to deploy only 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
exceed preset thresholds. Only during
these events will they provide their
supplemental protection.
The driver and passenger should always
wear their seat belts .Otherwise it is not
possible for air bags to provide their
supplemental protection.
In case of other types of impacts and
impacts below air bag deployment
thresholds, air bags will not deploy. The
driver and passenger will then be
protected to the extent possible by a 32

properly fastened seat belt. A properly
fastened seat belt is also needed to
provide the best possible protection in
a rollover.
We caution you not to rely on the presence
of the air bags in order to avoid wearing
your seat belt.
It is important to your safety and that of
your passenger that you replace deployed
air bags and repair any malfunctioning
air bags to make sure the vehicle will
continue to provide supplemental crash
protection for occupants.
Safety guidelines for the seat belt,
Emergency Tensioning Devices (ETDs)
and air bag G
WARNING
R Damaged seat belts or seat belts that have
been highly stressed in an accident must
be replaced and their anchoring points
must also be checked. Only use seat belts
installed or supplied by an authorized
electric drive smart center.
R Air bags and Emergency Tensioning
Devices (ETDs) contain Perchlorate
material, which may require special
handling and regard for the environment.
Check with your local government’s
disposal guidelines. California
residents, see http://www.dtsc.ca.gov/
HazardousWaste/Perchlorate/index.cfm .
R Given the considerable deployment
speed, required inflation volume, and
the textile structure of the air bags,
there is the possibility of abrasions or
other, potentially more serious injuries
resulting from air bag deployment.
R Air bags and Emergency Tensioning
Devices (ETDs) are designed to function
on a one-time-only basis. An air bag or
ETD that has deployed must be replaced.
R Do not pass seat belts over sharp edges.
They could tear. R
Do not make any modification that could
change the effectiveness of the seat
belts.
R No modifications of any kind may be made
to any components or wiring of the SRS.
This includes changing or removing any
component or part of the SRS, the
installation of additional trim
material, badges, etc. over the steering
wheel hub, passenger front air bag cover,
outboard sides of the seat backrests, and
installation of additional electrical/
electronic equipment on or near SRS
components and wiring. Keep area
between air bags and occupants free from
objects (e.g. packages, purses,
umbrellas, etc.).
R Do not bleach or dye seat belts as this may
severely weaken them. In acrash they may
not be able to provide adequate
protection.
R Do not hang hangers on the coat hooks or
handles over the door. These items may
turn into projectiles and cause head and
other injuries when the head-thorax air
bag is deployed.
R Air bag system components will be hot
after an air bag has inflated. Do not touch
them.
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 In addition, improper repair work on the
SRS creates a risk of rendering the SRS
inoperative or causing unintended air
bag deployment. Work on the SRS must
therefore only be performed by qualified
technicians. Contact an authorized
electric drive smart center.
R For your protection and the protection of
others, when scrapping the air bag unit
or Emergency Tensioning Devices (ETDs),
our safety instructions must be followed.

How an air bag operates An air bag is inflated in a matter of
milliseconds. If an air bag is triggered,
the SRS indicator lamp
000Ain the
instrument cluster illuminates.
! If the air bags are activated, you will
hear a loud noise and some dust may be
generated. The explosion fundamentally
represents no risk to your hearing.
An inflated air bag slows down and reduces
the movement of the occupant. When the
occupant makes contact with a front air bag
or head-thorax air bag (cabriolet only),
hot gas flows out of the inflated front air
bags and head-thorax air bags (cabriolet
only). This reduces the load on the
occupant’s head and upper body. These air
bags are consequently deflated after the
accident.
Driver front air bag/passenger front air
bag The front air bags are designed to reduce
the potential of injury in certain frontal
impacts.
Driver front air bag and passenger front
air bag are deployed
R
at the start of an accident with high
vehicle deceleration in the longitudinal
direction
R independently of other air bags in the
vehicle being deployed
R never in the event of arollover, unless
high vehicle deceleration in the
longitudinal direction is detected
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 unfastened 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)
(Y
page 37).
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
R the system, based on OCS weight sensor
readings, senses that the passenger seat
is occupied and the 00090007
indicator lamp is not lit (Y page 39)
R the impact exceeds a preset deployment
threshold
The driver front air bag is located in the
steering wheel housing, the passenger

Knee bags
0002
Driver’s knee bag
0003 Passenger knee bag
The knee bags are designed to provide
increased protection for the driver and
passenger against the risk of injuries to
the knees, thighs and lower legs. The knee
bags are located on the lower instrument
panel. They are designed to operate
together with the front air bags in certain
frontal impacts if the system determines
that air bag deployment can offer
additional protection to that provided by
the seat belts. Knee bags operate best in
conjunction with a properly positioned
and fastened seat belts.
Head-thorax air bags (cabriolet only) G
WARNING
There is a possibility for a head-thorax air
bag related injury if occupants, especially
children, are not properly seated or
restrained when next to a head-thorax air
bag which needs to deploy rapidly in a side
impact in order to do its job.
To help avoid the possibility of injury,
please follow these guidelines:
(1) Occupants, especially children, should never place their bodies
or lean their heads in the area of
the door where the head-thorax
air bag inflates. This could
result in serious injuries or death shoul
dthe head-thorax air
bag be deployed.
(2) Always sit as upright as possible, properly use the seat
belts, and for all children
12 years old or under, use an
appropriately sized infant
restraint, toddler restraint, or
booster seat recommended for
the size and weight of the child.
(3) Always wear seat belts properly. G
WARNING
Only use seat covers which have been tested
and approved by smart for your vehicle
model. A seat cover must have adeployment
control seam for the head-thorax air bag.
Using other seat covers may interfere with
or prevent the deployment of the head-
thorax air bags. Contact an authorized
electric drive smart center for
availability.
