Thorax-pelvis side air bags
Thorax-pelvis side air bags are designed
to provide increased protection for the
thorax and pelvis, but not the arms.
Thorax-pelvis side air bags are deployed
R
on the impacted side of the vehicle
R
in instances with a high rate of lateral
vehicle deceleration or acceleration
R
independently of the front air bags
R
regardless of whether the seat belt on the
impacted side of the vehicle is in use
R
independently of the ETDs.
Thorax-pelvis side air bags will generally
not deploy in a rollover.
The thorax-pelvis side air bags will
deploy, however, if the system detects
R
a high rate of lateral vehicle
deceleration or acceleration, and
R
that air bag deployment can offer
additional protection to that provided
by the seat belt.
The thorax-pelvis side air bags are
integrated into the driver and passenger
seat backrests.

Occupant Classification System
The Occupant Classification System (OCS)
automatically turns the passenger front air
bag on or off based on the classified
occupant weight category determined by
weight sensor readings from the passenger
seat.
i
Based on the classified occupant
weight category determined by weight
sensor readings from the passenger seat,
the system does also deactivate
R
head-thorax air bag (cabriolet)
R
the window curtain air bag (coupé)
R
the thorax-pelvis side air bag (coupé)
R
the seat Emergency Tensioning
Devices
R
the seat belt force limiter.
Occupants must sit properly belted in a
position that is as upright as possible with
their back against the seat backrest and
feet on the floor to be correctly classified.
If the occupant’s weight is transferred to
another object in the vehicle (e.g. by
leaning on armrests), the OCS may not be
able to properly approximate the
occupant’s weight category.
i
If the seat, including the trim cover and
cushion, needs to be serviced in any way,
take the vehicle to an authorized
electric drive smart center. Only seat
accessories approved by smart may be
used.
Both driver and the passenger should
always use the
4 0 indicator
lamp as an indication of whether or not
the passenger is properly positioned
(
Y
page 39).
G
WARNING
If the
4 0
indicator lamp
illuminates when an adult or someone
larger than a small individual is in the
passenger seat, have the passenger re-
position himself or herself in the seat
until the
4 0 indicator lamp
goes out.
In the event of a collision, the air bag
control unit will not allow passenger front
air bag deployment when the OCS has
classified the passenger seat occupant as
