Seat, seatbelt and SRS airbags

– CONTINUED –

! Operation

A) SRS curtain airbags operation
B) SRS side airbags operation

The SRS side airbag and SRS curtain airbag can func-

tion only when the ignition switch is in the “ON” posi-

tion.

The driver’s and front passenger’s SRS side airbags

and SRS curtain airbags deploy independently of each

other since each has its own impact sensor. There-

fore, they may not both deploy in the same accident.

Also, the SRS side airbag and SRS curtain airbag de-

ploys independently of the driver’s and front passen-

ger’s SRS frontal airbags in the steering wheel and in-

strument panel.

An impact sensor is incorporated into each of the ve-

hicle’s center and rear pillars. If either sensor detects

a certain predetermined amount of force during a side

impact collision, the control module sends a signal to

the side airbag module and curtain airbag module on

the impacted side of the vehicle, instructing them to in-

flate the SRS side airbag and SRS curtain airbag.

Then the side airbag module and curtain airbag mod-

ule produces gas, which instantly inflates the SRS

side airbag and SRS curtain airbag. After the deploy-

ment, the SRS side airbag immediately starts to de-

flate. 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 fol-

lowing deployment then slowly deflates.

The SRS side airbag and SRS curtain airbag deploys

even when no one occupies the seat on the side on

which an impact is applied.

When the SRS side airbag and SRS curtain airbag de-

ploys, a sudden, fairly loud inflation noise will be heard

and some smoke will be released. These occurrences

are normal result of the deployment. This smoke does

not indicate a fire in the vehicle.
