General Service Precautions

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 IN A FRONTAL COLLISION OR DEPLOYMENT OF THE AIR BAG FOR CONDITIONS LESS SEVERE THAN INTENDED.

IMPORTANT: The following SIR system components must be replaced after a frontal crash involving air bag deployment:
- Sensing and Diagnostic Module (SDM)
- Driver inflator module
- Passenger inflator module

In all types of accidents regardless of air bag deployment, visually inspect the following components and their mounting points and replace as required:
- Driver inflator module
- Steering wheel
- SIR coil assembly
- Steering column
- Steering column foam energy absorber
- Driver seat and belts
- Passenger inflator module
- Passenger seat and belts
- SDM
- Knee bolsters and instrument panel mounting attachments

Inspect the SIR coil assembly wiring and steering wheel for any signs of scorching, melting, or damage due to excessive heat. If the coil assembly wire or steering wheel is damaged, replace them. The steering column and wheel must be dimensionally checked to determine if they are damaged.

Never use SIR parts from another vehicle.
Do not attempt to repair the driver or passenger inflator modules, the steering wheel, the SIR coil assembly, the steering column, or the SDM. Service of these items is by replacement only. Verify replacement part numbers. No periodic maintenance of SIR components or system is required.
