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.
Ignition Switch Interlock
An interlock and security feature (ignition switch interlock) is mechanically connected to the ignition switch by a cable. The ignition switch interlock is controlled by the position of the lock cylinder in the ignition switch and by the position of the gear selector. This means that the gear selector must be in the P position for the ignition key to be removed from the ignition switch. The ignition key must be turned to position I or II before the lever can be moved from the P-position. The ignition switch interlock is used only in combination with shift-lock.
