8B-6 Air Bag System:

General Description

Air Bag System Construction

S6JB0B8201001

With the air bag system which includes front air bags,
side curtain-air bag and side-air bags for both the
driver’s and passenger’s sides as well as the seat belt
pretensioners, the sag of the seat belt is taken up (for
seat belt with pretensioner), the driver air bag (inflator)
module is deployed from the center of the steering
column and the passenger air bag (inflator) module from
the top of the instrument panel in front of the front
passenger seat in occurrence of a front collision with an
impact larger than a certain set value to supplement
protection offered by the driver and front passenger seat
belts.
Side-air bag (inflator) module is deployed from the side
of the seat back in occurrence of a sideward collision
with an impact larger than a certain set value.
Side curtain-air bag (inflator) module is deployed from
the roof side in occurrence of a sideward collision with
an impact larger than a certain set value.

The air bag system is designed to activate only in severe
frontal and sideward collisions. It is not designed to
activate in rear impacts, rollovers, or minor frontal and
sideward collisions, since it would offer no protection in
those types of accidents.

Air Bag System Input / Output Table

S6JB0B8201002

There are two types of air bag system of this model
• Consisting of 4 items, i.e., air bags for driver and front passenger and seat belts with pretensioner for driver and

front passenger sides

• Consisting of 8 items, i.e., air bags for driver and front passenger, seat belts with pretensioner for driver and front

passenger sides, side-air bags for driver and front passenger and curtain-air bags for driver and front passenger
sides
The side-air bag and curtain-air bag on the same side deploy at the same time only when an impact is applied to
that side. For the details, refer to the table below.
