Located near the center of the wheel, in the rear, are two T30 Torx screws. These screws are retained in the wheel by clips, loosen them until the air bag comes free, screws remain in the wheel. |
Lift off the air bag and disconnect the wiring to the bag. |

DANGER: Place the air bag face up, outside of the vehicle, preferably in the trunk, where no injury can occur if it deploys. While it is highly unlikely that a disconnected air bag will deploy, the potential result of such a deployment requires due care be taken.

NOTE: Each screw has an insulating washer, plus each hole in the contact has a plastic support and a spring behind it. Horn is activated when this contact plate touches the main metal section of the steering wheel at the top or bottom. |
