• The Side Impact SRS Side Curtain Airbags are de-
signed to activate only in certain side or rollover
collisions. When the Occupant Restraint Control
(ORC) detects a collision requiring the window bags to
inflate, it signals the inflators on the crash side of the
vehicle, and both sides of the vehicle when rollover is
sensed. A quantity of nontoxic gas is generated to
inflate the window bag. The inflating window bag
pushes the outside edge of the headliner out of the
way and covers the window. The airbag inflates in
about 30 milliseconds (about one-quarter of the time it
takes to blink your eyes) with enough force to injure
you if you are not belted and seated properly, or if
items are positioned in the area where the window bag
inflates. This especially applies to children. The win-
dow bag is only about 3 in (8 cm) thick when it is
inflated.
• The Knee Impact Bolsters help protect the knees of
the driver and the front passenger, and position every-
one for the best interaction with the front airbag.
If a Deployment Occurs
The airbag system is designed to deploy when the
Occupant Restraint Control (ORC) detects a moderate-to-
severe frontal collision, to help restrain the driver and
front passenger, and then to immediately deflate.
NOTE: A frontal collision that is not severe enough to
need airbag protection will not activate the system. This
does not mean something is wrong with the airbag
system.
