How Does The Side Air Bag System Work? - Ford Focus 2004 Owner's Manual

Do not lean your head on the door. The side air bag could injure
you as it deploys from the side of the seatback.
Do not attempt to service, repair, or modify the air bag SRS, its
fuses or the seat cover on a seat containing an air bag. See your
Ford or Lincoln Mercury dealer.
All occupants of the vehicle should always wear their safety belts
even when an air bag SRS is provided.

How does the side air bag system work?

The side air bag system consists of
the following:
• An inflatable nylon bag (air bag)
with a gas generator concealed
behind the outboard bolster of
the driver and front passenger
seatbacks.
• A special seat cover designed to
allow air bag deployment.
• The same warning light,
electronic control and diagnostic
unit as used for the front air
bags.
• Two crash sensors located under
the outboard side of the front
seats, attached to the floor.
Side air bags, in combination with seat belts, can help reduce the risk of
severe injuries in the event of a significant side impact collision.
The side air bags are fitted on the outboard side of the seatbacks of the
front seats. In certain lateral collisions, the air bag on the side affected
by the collision will be inflated, even if the respective seat is not
occupied. The air bag was designed to inflate between the door panel
and occupant to further enhance the protection provided occupants in
side impact collisions.
The air bag SRS is designed to activate when the vehicle sustains lateral
deceleration sufficient to cause the sensors to close an electrical circuit
that initiates air bag inflation.
