Caution: This vehicle is equipped with a Supplemental Inflatable Restraint (SIR) System. Failure to follow the correct procedure could cause the following conditions:
• Air bag deployment • Personal injury • Unnecessary SIR system repairs • Refer to SIR Component Views in order to determine if you are performing service on or near the SIR components or the SIR wiring. • If you are performing service on or near the SIR components or the SIR wiring, disable the SIR system. Refer to Disabling the SIR System.
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
Tighten
Tighten the fasteners to 10 N·m (89 lb in).
Important: After a non-deployment accident, visually inspect the knee bolster for damage or deformation. Any visible damage may indicate structural damage to the IP assembly.

The knee bolster consists of the following components:
• | The tie bar |
• | The steering column filler |
The knee bolster is located in the base of the instrument panel (IP) trim panel. The knee bolster extends across the entire IP assembly. The knee bolster is mounted directly to the IP trim panel. The IP trim panel crosses over the top of the steering column and mounts to the steering column upper support. The steering column filler is the only component of the knee bolster that you may replace. The tie bar is an integral part of the IP assembly.
After a non-deployment accident, visually inspect the knee bolster for damage or deformation. Any visible damage indicates other structural damage. The knee bolster cannot be repaired or replaced separately from the IP assembly. The IP assembly must be replaced.
When replacing the knee bolster, note the GM part number. Compare the part numbers at installation in order to ensure that you are installing the correct knee bolster. Refer to Instrument Panel Assembly Removal .
