19. ENABLING/DISABLING AUTO DOOR LOCK FUNCTION
a. To disable auto door lock:
(1) Enter the vehicle and shut all doors.
(2) Insert the key into the ignition cylinder and turn it to the ON position (not ACC).
(3) Open the driver's door and keep it open.
(4) Turn the key to the LOCK position and remove it from the ignition cylinder.
(5) Insert the key into the ignition cylinder and remove it. Repeat this operation three more times. (End this step with the key out of the ignition cylinder.)
(6) Push the "UNLOCK" button on the driver's door master switch 5 times within 10 seconds. Wait at least 10 seconds and shut the driver's door.
(7) Verify auto lock operation has been disabled by starting the engine, putting the vehicle into a gear and releasing the brake pedal.

b. To enable auto door lock:
Follow the same sequence as above, except step 6. In step 6, push the "LOCK" button on the driver's door master switch 5 times within 10 seconds. Wait at least 10 seconds and shut the driver's door.
