Intelligent Key Interlock Storage Procedure
Performing the following operation associates the regist ered driving position with Intelligent Key. When driver
door unlock operation is performed by Intelligent Key or driver door request switch, display of the registered
driving position and turnout operation can be performed.
1.STEP 1
Check the following conditions.
 Ignition switch: OFF
 Initialization: done
 Driving position: registered
>> GO TO 2.
2.STEP 2
1. Push set switch. NOTE:
Memory indicator for which driver seat position is already retained in memory is illuminated for 5 seconds.
2. Push the Intelligent Key unlock button within 5 seconds after pushing memory switch (while the memory indicator is turned ON).
NOTE:
From the time registration is performed, the app licable memory indicator blinks for 5 seconds.
