Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Inertia Switch
The inertia switch is located under the hood on the right hand side of the bulkhead (view from front bumper).
In the event of the inertia switch being triggered in an accident, the doors will unlock, the windows will open, the interior lights will be illuminated and the hazard warning lights activated.
Inertia Switch Update
Beginning with vehicles produced 09/02, the inertia switch has been eliminated. All functions previously performed by the inertia switch are now done by the MRS4 Control Module.
