Shift Interlock: Description and Operation

When the Ignition Switch is in the "ON" position or during Retained Accessory Power, the shift interlock system prevents the driver from shifting the vehicle from park unless the brake pedal is depressed. Once the brake pedal is depressed, the solenoid is de-energized. The restrictor arm moves clear of the shift lever arm, allowing the gear selector to operate normally. The shift interlock system can be overridden and the hide can be shifted by turning the Ignition Switch to "OFF." This removes battery voltage at the solenoid, leaving it de-energized

IMPORTANT Open any door on vehicles equipped with Retained Accessory Power (RAP) to remove battery voltage at the solenoid.Refer to Steering And Suspension for further information.
