Supplemental Inflatable Restraints

REPAIRS AND INSPECTIONS REQUIRED AFTER A COLLISION

ACCIDENT WITH OR WITHOUT INFLATOR MODULE DEPLOYMENT - COMPONENT INSPECTIONS

CAUTION:
- Proper operation of the Supplemental Inflatable Restraint (SIR) sensing system requires that any repairs to the vehicle structure return the vehicle structure to the original production configuration. Not properly repairing the vehicle structure could cause non-deployment of the air bag(s) in a frontal collision or deployment of the air bag(s) for conditions less severe than intended.
- Proper operation of the Supplemental Inflatable Restraint (SIR) sensing system requires that any repairs to the vehicle structure return the vehicle structure to the original production configuration. Not properly repairing the vehicle structure could cause non-deployment of the side impact air bag(s) in a side impact collision or deployment of the side impact air bag(s) for conditions less severe than intended.


- The steering column -Perform the steering column accident damage checking procedures. Refer to Steering Column Accident Damage Inspection in Steering Wheel and Column.
- The I/P knee bolsters and mounting points Inspect the knee bolsters for bending, Twisting, buckling, or any offer type of damage.
- The I/P brackets, braces etc.- Inspect for bending, Twisting, buckling, or any offer type of damage.
