Driver And Passenger Advanced Front Air Bag
Inflator Units
The Driver and Passenger Advanced Front Air Bag Inflator
Units are located in the center of the steering wheel and on
the right side of the instrument panel. When the ORC detects
a collision requiring the Advanced Front Air Bags, it signals
the inflator units. A large quantity of non-toxic gas is
generated to inflate the Advanced Front Air Bags. Different
air bag inflation rates are possible, based on several factors,
including the collision type and severity. The steering wheel
hub trim cover and the upper right side of the instrument
panel separate and fold out of the way as the air bags inflate
to their full size. The air bags fully inflate in about 50 to 70
milliseconds. This is about half of the time it takes to blink
your eyes. The air bags then quickly deflate while helping to
restrain the driver and front passenger.
The Advanced Front Air Bag gas is vented through the
vent holes in the sides of the air bag. In this way, the air
bags do not interfere with your control of the vehicle.
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 79
Supplemental Seat-Mounted Side Air Bag (SAB)
Inflator Units
The Supplemental Seat-Mounted Side Air Bags are de-
signed to activate only in certain side collisions.
The ORC determines if a side collision requires the side
air bags to inflate, based on the severity and type of
collision.
Based on the severity and type of collision, the side air
bag inflator on the crash side of the vehicle may be
triggered, releasing a quantity of non-toxic gas. The
inflating SAB exits through the seat seam into the space
between the occupant and the door. The SAB fully inflate
in about 10 milliseconds. The side air bag moves at a very
high speed and with such a high force that it could injure
you if you are not seated properly, or if items are
positioned in the area where the side air bag inflates. This
especially applies to children.
