32 - SUPPLEMENTAL RESTRAINT SYSTEM
Seat belt pretensioner function:
 At the moment of collision, the pretensioner retracts the seat belt before occupant moves forward, and
restraints occupant onto the seat, then locks the seat belt to prevent occupant from leaning forward, thus
protecting occupant safety.
 Seat belt pretensioner works with airbag. Once frontal collision impact is detected higher than specified
valve, the seat belt with pretensioner will work together with the airbag system to protect occupant safety.
Operation
Supplemental restraint system can improve the safety of occupants only when used in combination with the
seat belts. Occupants must fasten their seat belts in order to gain full protection from the supplemental
restraint system.
Supplemental restraint system circuit is continuously monitored and controlled by the SRS control module
assembly. The airbag indicator on instrument cluster illuminates for approximately 3 seconds for a test each
32
time ignition switch is turned ON. The airbag indicator goes off after the test is completed. If the indicator
comes on at any time other than the test time, it indicates that there is a problem in the supplemental restraint
system circuit.
Whether the airbag deploys or not depends on the angle and severity of the impact. When vehicle is
subjected to severe collision, the microprocessor in supplemental restraint system sends signals to the
corresponding inflator units of airbag to deploy the airbags quickly , thus protecting occupants.
CAUTION
 Before removing airbag system components, disconnect the negative battery cable at least 90 seconds.
Before servicing steering system, remove the driver airbag and spiral cable for safekeeping.
 If vehicle has been involved in a minor collision but the airbags do not deploy, always inspect the airbag
components.
 If airbag may be touched during servicing, remove the airbag as necessary for safekeeping before
servicing.
 Never use airbag components from another vehicle. When replacing the airbag components, replace
with new ones.
 If an airbag component is dropped or if there are any cracks, dents or other defects in the case, bracket
or connector, replace the airbag component with a new one.
 Information labels are attached to the periphery of airbag components. Always follow the cautions and
instructions on labels.
WARNING
 Never expose airbag components directly to hot air or open flames.
 Never attempt to disassemble or repair airbag components.
 The removed airbag should be kept properly. Never put other objects on it. If triggered accidentally, the
airbag may cause personal injury.
 As a disposable component, the airbag must be replaced after deployment and avoid reusing it.
 Always dispose of vehicle together with airbag, or the airbag may be triggered accidentally to cause
personal injury.
