The shift interlock system prevents you from shifting the vehicle from PARK unless you press the brake pedal. The system activates when you turn the ignition switch to RUN.

When you press the brake pedal, you de-energize the shift interlock actuator. The restrictor arm moves clear of the shift lever arm. This movement allows the gear selector to operate normally.

Turn the ignition switch to OFF in order do the following operations:

1. In order to override the shift interlock system
2. In order to shift the vehicle.

When you turn the ignition switch to OFF, you remove battery voltage from the actuator. The actuator de-energizes.
