1-62 Seat, seatbelt and SRS airbags

left and right center pillars and rear wheel

houses. In addition, the rollover sensor is

inside the airbag control module.

If a center pillar impact sensor senses 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. If it is a rear wheel

house impact sensor alone that senses a

sufficiently strong impact force, the control

module causes only the SRS curtain

airbag on the impacted side to inflate. If

the rollover sensor detects rollover of the

vehicle, the control module inflates the

curtain airbag.

After deployment, the SRS side airbag

immediately starts to deflate. The time

required from detection of an impact to

deflation of an SRS side airbag af ter

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.

When the SRS si de airbag and SRS

curtain airbag deploy, a sudden, fairly loud

inflation noise will be heard and some

smoke will be released. These occur-

rences are a normal result of the deploy-

ment. This smoke does not indicate a fire

in the vehicle.

CAUTION

Do not touch the SRS side airbag

system components around the

front seat seatback with bare hands

right after deployment. Doing so can

cause burns because the compo-

nents can be very hot as a result of

deployment.

After deployment, do not touch any

part of the SRS curtain airbag

system (from the front pillar to the

part of the roof side over the rear

seat). Doing so can cause burns

because the components can be

very hot as a result of deployment.

The SRS side airbag and SRS curtain

airbag are designed to deploy in the event

of an accident involving a moderate to

severe side impact collision. Also, in the

case of a rollover, the SRS curtain airbag

deploys. They are basically not designed

to deploy in a lesser side impact. Also,

they are basically not designed to deploy

in frontal or rear impacts because SRS

side airbag and SRS curtain airbag

deployment would not help the occupant

in those situations.

Each SRS side airbag and SRS curtain

airbag are designed to function on a one-

time-only basis.

SRS side airbag and SRS curtain airbag

deployment depend on the level of force

experienced in the passenger compart-

ment during a side impact collision. That

level differs from one type of collision to

another, and it may have no bearing on

the visible damage done to the vehicle

itself. Also, the SRS curtain airbag de-

ploys depending on the vehicle’s position

and inclination at the time of the rollover.
