ACTIONS TO TAKE AFTER REMOVING BATTERY OR DISCONNECTING GROUND TERMINAL OF BATTERY SENSOR

When removing the battery or disconnecting the battery terminal, always be sure to turn the ignition switch to OFF and disconnect the ground terminal from the battery sensor first. When removing the battery or disconnecting the battery terminal, power supply is cut off and the information stored in the computer memory is volatilized. Therefore, setting information of some devices is initialized to the factory default. The device and functions initialized by removing battery are as follows.

No.	Item	Job contents when connecting battery
1	Center information display (CID)	Clock: Set to the current time. 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. Temperature setting of fully automatic air conditioner (settings that the customer set): Set to the contents checked before disconnecting the battery.
2	Steering lock system (model with keyless access with push button start)	If the engine does not start, initialize the steering lock system. For the initialization procedure, refer to "KEYLESS ACCESS WITH PUSH BUTTON START SYSTEM (DIAGNOSTICS)" information. Refer to KEYLESS ACCESS WITH PUSH BUTTON START (DIAGNOSTICS)>DIAGNOSTICS WITH PHENOMENON>INSPECTION>ENGINE DOES NOT START .
3	EyeSight (model with EyeSight)	Set to the contents checked before disconnecting the battery.
4	Electronic throttle system	Turn the ignition switch to ON, wait for 10 seconds or more, and start the engine.
5	Engine control system	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.
6	Telematics	Perform the Bluetooth connection procedure between head unit (without navigation) and smartphone. Refer to REPAIR CONTENTS>NOTE>Bluetooth CONNECTION PROCEDURE BETWEEN HEAD UNIT (AUDIO WITHOUT NAVIGATION) AND SMARTPHONE .
7	Past trouble history (memory code)	-

- Clean the battery cable terminals and apply grease to retard the formation of corrosion.
- Connect the positive terminal of the battery, and then connect the ground terminal to the battery sensor.
- Some DTCs may be detected, so after connecting the ground terminal to the battery sensor, wait for 10 seconds or more and then turn the ignition switch to ON.
- After the battery is installed, initial diagnosis of the electronic throttle control is performed. Wait for 10 seconds or more after turning the ignition switch to ON, and then start the engine.
