VOLVO SRS
As an enhancement to the three-point seat belt
system, your Volvo is equipped with a
Supplemental Restraint System (SRS). The Volvo
SRS consists of airbags (2) and knee bolsters (5)
on both the driver's and passenger's sides and seat
belt tensioners in both front door pillars (4). The
system is designed to supplement the protection
provided by the three-point seat belt system.
The SRS system is indicated by the "SRS"
embossed on the steering wheel pad and above
the glove compartment, the knee bolsters beneath
the steering column and the glove compartment
and decals on both sun visors and on the far right
side of the dash.
The airbags are folded and located in the center of
the steering wheel and above the glove
compartment. They are designed to deploy during
certain frontal or front-angular collisions,
impacts, or decelerations, depending on the crash
severity, angle, speed and object impacted. Both
airbags and seat belt tensioners will deploy, even
if the passenger seat is not occupied.
The airbag system includes gas generators (1)
surrounded by the airbags (2) and front seat belt
tensioners for both of the front seats (4). To deploy the
system, the sensor (3) activates the gas generators
causing the airbags to be inflated with nitrogen gas. As
the movement of the seats' occupants compresses the
airbags, some of the gas is expelled at a controlled rate
to provide better cushioning. Both seat belt tensioners
also deploy, minimizing any seat belt slack.
The entire process, including inflation and deflation of
the airbags, takes approximately two-tenths of a second.
WARNING!
When installing any optional equipment make sure
that the SRS system is not damaged. Do not attempt
to service any component of the SRS yourself.
Attempting to do so may result in serious personal
injury. If a problem arises, take your car to the
nearest authorized Volvo Retailer for inspection as
soon as possible.
