Shift Interlock System

The shift interlock system prevents the shifting from PARK unless the brake pedal is depressed. The shift interlock system consists of a shift lock actuator mounted on the base of the floor shift housing. If the ignition switch is in the RUN position, the shift lock actuator is continually on unless the brake pedal is depressed.

If the selector lever will not move out of park with the key in the ON position it will need to be unlocked manually.

  1. Make sure that the transmission range selector lever is in the PARK position.
