Seat, seatbelt and SRS airbags/*SRS airbag (Supplemental Restraint System airbag)
deploys independently of the driver’s and
front passenger’s SRS frontal airbags in
the steering wheel and instrument panel.
An impact sensor, which senses impact
force, is located in each of the following
locations.
. In the left and right front doors
. In the left and right center pillars
. In the left and right rear wheel houses
. In the airbag control module
. In the left and right front fenders (only
SRS curtain airbags are designed to
deploy when the front sub sensors sense
a severe impact.)
A rollover sensor is also located inside the
airbag control module.
If both of the following sensors together
sense an impact force above a predetermined level in a side collision, the control
module causes both the SRS side airbag
and curtain airbag on the impacted side
to inflate regardless of whether the rear
wheel house impact sensor on the same
side senses an impact.
. the impact sensor that is located in the
airbag control module
. one of the center pillar impact sensors
or front door impact sensors
If both of the following sensors together
sense an impact force above a predetermined level in a side collision, the control
module causes only the SRS curtain
airbag on the impacted side to inflate.
. the impact sensor that is located in the
airbag control module
. one of the rear wheel house impact
sensors
Even if a frontal collision occurs, both right
and left SRS curtain airbags will deploy
when the front sensor and the control unit
determine that the impact results from an
offset frontal collision.
T he SRS curtain airbags are designed to
deploy under the following conditions.
. The driver’s SRS frontal airbag deploys
or the driver’s and passenger’s SRS
frontal airbags deploy in a frontal collision.
. The system determines that the collision is an offset frontal collision.
. The vehicle is in an extremely inclined
state such as during a rollover.
The SRS curtain airbags are basically not
designed to deploy in the following cases.
. In a frontal collision when the SRS
frontal airbags do not deploy or the system
determines that the collision is other than
an offset frontal collision
. In most lesser inclined states
If the rollover sensor detects rollover of the
vehicle, the control module inflates the
SRS curtain airbags. At this time, the
driver’s and front passenger’s seatbelt
pretensioners also operate at the same
time.
After the deployment, the SRS side airbag
immediately starts to deflate. The time
required from detection of an impact to
deflation of an SRS side airbag after
deployment is shorter than the blink of
an eye.
The SRS curtain airbag remains inflated
for a while following deployment then
slowly deflates.
The SRS side airbag and SRS curtain
airbag deploy even when no one occupies
the seat on the side on which an impact is
applied.
The SRS side airbag and SRS curtain
airbag are designed as follows:
. to deploy in the event of an accident
involving a moderate to severe side
impact collision
. to function on a one-time-only basis.
The SRS side airbag and SRS curtain
airbag are not designed to deploy in the
following cases:
. in most lesser side impacts
