To find it, you'll likely need to:
* Consult your owner's manual: This is the best place to start. The manual should have a diagram showing the location.
* Look under the passenger side of the dashboard: Feel around carefully for a small, usually square or rectangular, box. It might be recessed or partially hidden behind trim panels.
* Check near the fuse box: Inertia switches are sometimes located near or even integrated with the fuse box area.
* Search online: Use a search engine with your Cadillac's specific model and year to find pictures or forum discussions showing where the inertia switch is located in similar vehicles.
If you can't locate it after trying these steps, a mechanic or Cadillac specialist can help.
