The SRS is a safety device which, when used with the seat belt, is designed to help protect the driver and front
passenger in a frontal Impact exceeding a certain set limit. The system consists of the SRS unit, including safing
sensor and impact sensor (A), the cable reel (B), the driver’s airbag (C), the front passenger’s airbag (D), side airbags
(E), seat belt tensioners (l), and front impact sensors (J). Since the driver’s and front passenger’s airbags use the same
sensors, both normally inflate at the same time. However, it is possible for only one airbag to inflate. This can occur
when the severity of a collision is at the margin, or threshold, that the determines whether or not the airbags will
deploy. In such cases, the seat belt will provide sufficient protection, and the supplemental protection offered by the
airbag would be minimal.
The front passenger’s weight sensors unit (K) is located under the front passenger’s seat along with the weight
sensors (L). The weight sensors detect the weight on the seat, and sends the information to the front passenger’s
weight sensors unit. If the total weight is about 65 lbs (30 kg) or less, the front passenger’s weight sensors unit sends a
signal to the SRS unit to prevent the passenger’s airbag from deploying. When the passenger’s airbag is disabled, the
passenger airbag cutoff indicator on the center panel comes on to alert the driver that the front passenger’s airbag will
not deploy in a front-end collision.
The driver’s seat position sensor (M) is under the driver’s seat on the inside of the left seat When the driver’s seat is
moved to its full forward position, the deployment of the driver’s airbag is moderated to decrease its force of impact
during a front-end collision.
