Inflator No.2
1. When the driver-side air bag module receives an operation (deployment) signal from the SAS control module,
the igniter built into inflator No.2 builds up heat and ignites the inflammation agent.
2. The ignition of the inflammation agent causes the combustion of a gas-generating agent which releases
nitrogen gas.
3. The nitrogen gas is cooled at the filter and the filtrate is injected into the air bag.

Inflator No.1
1. When the passenger-side air bag module receives an operation (deployment) signal from the SAS control
module, the igniter built into inflator No.1 builds up heat and ignites the inflammation agent.

nitrogen gas.
3. The nitrogen gas is cooled at the filter and the filtrate is injected into the air bag.

SIDE AIR BAG MODULE FUNCTION
E5U081000147N01
• During a collision to the side of the vehicle, the air bag operates (deploys) after receiving an operation signal
from the SAS control module, defusing impact to the head and chest areas of the driver or front passenger.

SIDE AIR BAG MODULE CONSTRUCTION/OPERATION
E5U081000147N02
Construction
• Side air bag modules are installed on the outboard sides of the seat backs.
• The side air bag module is composed of an inflator and air bag.
• When the air bag operates (deploys), the seat back trim is spread apart by argon gas generated from the
inflator, inflating the air bag.
• The inflator operates in the following order:
1. The igniter built into the inflator begins to build up heat when the operation (deployment) signal is sent from
the SAS control module. The inflation agent is ignited by the build up of heat in the igniter.
2. The argon gas expands due to the heat of the ignited inflation agent.
3. The expanding argon gas breaks the discharge barrier, is cooled and filtered by the filter, and then injected
into the air bag.

PRE-TENSIONER SEAT BELT FUNCTION
E5U081057630N01
• When a vehicle is involved in a frontal or frontal offset collision and the front seat belts are buckled, the
pretensioner seat belt system receives an operation signal from the SAS control module, retracting and
tightening the belt webbing instantly on the driver and front passenger restraints.

Construction
Operation
Normal (Seat Belt Pretensioners Not Operating)
• Normally, the clutch roller installed to the outer circumference of the spindle sits in the recess of the gear and
does not interfere with the spindle.
• The gear does not rotate when the belt is pulled or retracted because the spindle and gear are not engaged.
