HINT:

When the cable is disconnected / reconnected to the auxiliary battery terminal, systems temporarily stop operating. However, each system has a function that completes learning the first time the system is used.

LEARNING COMPLETES WHEN VEHICLE IS DRIVEN

Effect/Inoperative Function When Necessary Procedures are not Performed	Necessary Procedures	Link
Stop and start system	Drive the vehicle until stop and start control is permitted (approximately 5 to 60 minutes).	Refer to PRECAUTION [12/2024 - ]
Front camera system	Drive the vehicle straight ahead at 35 km/h (22 mph) or more for 5 seconds or more.	Refer to INITIALIZATION [12/2024 - ]

LEARNING COMPLETES WHEN VEHICLE IS OPERATED NORMALLY

Effect/Inoperative Function When Necessary Procedures are not Performed	Necessary Procedures	Link
Air conditioning system	After the ignition switch is turned to ON, the servo motor and expansion valve standard position is recognized.	-
Power running board system	After turning the ignition switch to ON, opening the door, and then fully deployed the power running board system, close the door and stowed the power running board system.	Refer to INITIALIZATION [12/2024 - ]
Power back door system*1	After the ignition switch is turned to ON, the servo motor and expansion valve standard position is recognized.	Refer to INITIALIZATION [12/2024 - ]
Power Door Lock Control System*2	Perform door unlock operation with door control switch or electrical key transmitter sub-assembly switch.	Refer to INITIALIZATION [12/2024 - ]

*1: w/ Power Back Door System
