Caution / Notice / Hint

The necessary procedures (adjustment, calibration, initialization or registration) that must be performed after parts are removed and installed, or replaced during engine coolant temperature sensor removal/installation are shown below.

NECESSARY PROCEDURES AFTER PARTS REMOVED/INSTALLED/REPLACED

Replaced Part or Performed Procedure	Necessary Procedure	Effect/Inoperative Function when Necessary Procedure not Performed	Link
Battery terminal is disconnected/reconnected	Turn the ignition switch to ON, wait for 10 seconds or more, and start the engine.	The electronic throttle system will initialized	-
	Let the engine run at idle until it fully warms up (the radiator fan turns 2 times or more) under no electrical load condition. After connecting the ground terminal to the battery sensor, wait for 10 seconds or more and turn the ignition switch to ON.	The engine control system will initialized	-
	Set the clock to the current time.	The clock on the meter display will initialized	-
	Set to the contents checked before disconnecting the battery.	The EyeSight system will initialized	-
	Audio (settings that the customer set): Set to the contents checked before disconnecting the battery. Navigation system (settings that the customer set): Time setting is not necessary because the time information is received via GPS. Navigation system (settings that the customer set): Set the sound and other settings (items that were set in the selection) to the contents checked before disconnecting the battery.	The audio and visual system will initialized	-
	Perform the Bluetooth connection procedure between head unit (without navigation) and smartphone.	The telematics system will initialized	-

HINT:

When the cable is disconnected / reconnected to the 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 OPERATED NORMALLY
