WITH INTELLIGENT KEY
• The mechanical key interlock mechanism also operates as a shift lock: With the ignition knob switch turned to ON, selector lever cannot be shifted from “P” position to any other
position unless brake pedal is depressed.
With the ignition knob switch turned to OFF, selector lever cannot be shifted from “P” position to any other
position.
• The shift lock and key interlock mechanisms are controlled by the ON-OFF operation of the shift lock sole- noid and by the operation of the ignition knob switch, respectively.
WITHOUT INTELLIGENT KEY
• The mechanical key interlock mechanism also operates as a shift lock:With the ignition switch turned to ON, selector lever cannot be shifted from “P” position to any other position
unless brake pedal is depressed.
With the key removed, selector lever cannot be shifted from “P” position to any other position.
The key cannot be removed unless selector lever is placed in “P” position.
• The shift lock and key interlock mechanisms are controlled by the ON-OFF operation of the shift lock sole-
noid and by the operation of the rotator and sli der located inside key cylinder, respectively.
