NOTE
The air bag can be retained to the steering wheel with several different types of fasteners, depending on Model Year and vehicle equipment. A small mirror may be helpful to examine the back of the steering wheel to determine how the air bag is retained on your vehicle. It could be by Torx®screws which are unscrewed using the proper bit (usually a #30 driver bit). An alternate method of attachment is by small leaf-type springs which are unclipped with a small flat-blade prytool.

  1. On the back side of the steering wheel, locate and remove the air bag fasteners.
  2.  
  3. Gently pull on the air bag module to free it from the steering wheel.
