Description
Available occupant restraints for this vehicle include both active and passive types. Active restraints are those which
require the vehicle occupants to take some action to employ, such as fastening a seat belt; while passive restraints
require no action by the vehicle occupants to be employed.
Active Restraints
•Front Seat Belts
• Rear Seat Belts
Passive Restraints
• Driver Airbag
• Passenger Airbag
• Seat Belt Tensioners
Operation
Active Restraints
The primary passenger restraints are the seat belts. Seat belts are referred to as an active restraint because the
vehicle occupants are required to physically fasten and properly adjust these restraints in order to benefit from them.
Passive Restraints
The passive restraints are referred to as a supplemental restraint system because they were designed and are
intended to enhance the protection for the occupants of the vehicle only when used in conjunction with the seat belts.
They are referred to as passive restraints because the vehicle occupants are not required to do anything to make
them operate; however, the vehicle occupants must be wearing their seat belts in order to obtain the maximum safety
benefit from the supplemental restraint system.
The supplemental restraint system electrical circuits are continuously monitored and controlled by a microprocessor
and software contained within the Restraints Control Module (RCM). An airbag indicator in the instrument cluster
illuminates for about seven seconds as a bulb test each time the ignition switch is turned to the ON or START posi-
tions. Following the bulb test, the airbag indicator is turned ON or OFF by the RCM to indicate the status of the
supplemental restraint system. If the airbag indicator comes ON at any time other than during the bulb test, it indi-
cates that there is a problem in the supplemental restraint system electrical circuits. Such a problem may cause
airbags not to deploy when required, or to deploy when not required.
Deployment of the supplemental restraints depends upon the angle and severity of an impact. When an impact is
severe enough, the microprocessor in the RCM signals the inflator of the appropriate airbag units to deploy their
airbag cushions. The front seat belt tensioners are provided with a deployment signal by the RCM in conjunction with
the front airbags.
