deploy during certain frontal or front-angular collisions, impacts, or decelerations, depending on the crash severity, angle,
speed and object impacted. The airbags may also deploy in certain non-frontal collisions where rapid deceleration occurs.
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!
· As its name implies, SRS is designed to be a SUPPLEMENT to - not a replacement for - the three-point belt system.
For maximum protection, wear seat belts at all times. Be aware that no system can prevent all possible injuries that may
occur in an accident.
· 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.
pg. 5 Volvo SRS
A self-diagnostic system incorporated into the sensor monitors the SRS. If a fault is detected, the "SRS" warning light will
illuminate. The light is included in the warning/indicator light cluster in the instrument panel. Normally, the SRS warning
lamp should light up when the ignition is switched on and should go out after 5 seconds or when the engine is started.
Check that this light is functioning properly every time the car is started.
