Understanding the Vehicle
air bags and/or side air bags in a frontal
or side collision or rollover event is
required. Based on the impact sensor's
signals, a central electronic ORC deploys
the advanced front air bags and SAB air
2
bags, as required, depending on the
severity and type of impact.
On top of what previously described, the
characteristics of the collision registered
by the sensors and sent to the control
unit of the ORC can also cause a sudden
cut of the power from the 12 V battery,
"blowing" the pyrotechnical charge
located on the positive battery terminal.
WARNING!
The control unit of the ORC cannot only
activate the pyrotechnical charge but,
when conditions require, it activates the
pyrotechnical charge and the air bags
simultaneously.
CAUTION!
After a collision that has caused the
blowing up of the pyrotechnical charge,
this must be replaced at a Service
Network.
Advanced front air bags are designed
to provide additional protection by
supplementing the seat belts in certain
frontal collisions depending on the
severity and type of collision.

Advanced front air bags are not
expected to reduce the risk of injury in
rear, side, or rollover collisions.
The advanced front air bags will not
deploy in all frontal collisions, including
those that may produce substantial
vehicle damage, for example, some pole
collisions, truck under rides, and corner
impacts. On the other hand, depending
on the type and location of impact,
advanced front air bags may deploy in
crashes with little vehicle front-end
damage but that produce a severe initial
deceleration.
The side air bags will not deploy in all
side collisions. Side air bag deployment
will depend on the severity and type
of collision. Because air bag sensors
measure vehicle deceleration over time,
vehicle speed and damage merely are
not good indicators of whether or not an
air bag should have deployed.
Seat belts are necessary for your
protection in all accidents, and also are
needed to help keep you in position,
away from an inflating air bag. The ORC
monitors the readiness of the electronic
parts of the air bag system whenever
the ignition device is in the ON position.
If the ignition device is in the STOP
position or not active, the air bag system
is not activated and the air bags will not
inflate.
Air bag Warning Light (NOT valid for
Taiwan market)
The ORC contains a backup power
supply system that may deploy the air
bags even if the battery has low power
or it becomes disconnected prior to
deployment. When starting the vehicle,
ORC turns on the air bag warning
light on the instrument cluster for
approximately 4 to 8 seconds for a test.
After the test, the air bag warning light
will turn off. If the ORC, during the
diagnosis phase detects a malfunction
that could affect the air bag system, it
turns on the air bag warning light and
the "Service Airbag System" message
either momentarily or continuously. The
diagnostics also record the nature of the
malfunction. A beep will sound if the
light illuminates again after initial startup.
The air bag warning light monitors the
internal circuits and interconnecting
