Automatic Door Locking

[Gazz_RX]

Hi, I am trying to turn off the automatic door locking when the speed reaches 20km/h.

I have tried to cancel this function by following the directions in the manual (page 23 for 08/09 RX350) and nothing changes.

Instruction is, Turn ignition ON, shift lever from P to N, within 10 seconds of turning ignition to ON press and hold the drivers side power door lock switch in the lock position for 5 seconds and then release. Doors should lock and unlock to indicate function is set. To cancel the function, do above operation again.

Does anybody know if this should work or is it a dealer setting?
