Actions to take after removing battery or disconnecting ground terminal

When removing the battery or disconnecting the battery terminal, always be sure to turn the ignition switch to OFF and disconnect the battery ground terminal 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	Clock	Set the clock to the current time.
2	MID	Set to the contents checked before disconnecting the battery.
3	Audio (settings that the customer set)	Set to the contents checked before disconnecting the battery.
4	Navigation system (settings that the customer set)	Time setting is not necessary because the time information is received via GPS. Set the sound and other settings (items that were set in the selection) to the contents checked before disconnecting the battery.
5	Temperature setting of fully automatic air conditioner (settings that the customer set)	Set to the contents checked before disconnecting the battery.
6	Power window system	Initialize automatic full open/close of driver's window (power window system). For the initialization procedure, refer to "GW" section. <Ref. to OPERATION , Power Window System.>
7	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 "KPS" section. <Ref. to ENGINE DOES NOT START , INSPECTION, Diagnostics with Phenomenon.>
8	EyeSight (model with EyeSight)	Set to the contents checked before disconnecting the battery.
9	Electronic throttle system	Turn the ignition switch to ON, wait for 10 seconds or more, and start the engine.
10	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 the battery ground terminal is connected, wait for 10 seconds or more to turn the ignition switch to ON.
11	Power rear gate	When the battery is connected again with the power rear gate opened, perform the initialization. (When the battery is connected again with the power rear gate closed, the initialization is automatically performed.) Refer to "PRG" section for initialization. <Ref. to INITIALIZATION , PROCEDURE, Power Rear Gate System.>

  NOTE:
  - Install the battery sensor while holding it by hand to prevent rotating.
  - Clean the battery cable terminals and apply grease to retard the formation of corrosion.
  - Connect the positive (+) terminal, and then connect the negative (-) terminal of the battery.
  - Since DTCs may be detected, after the battery ground terminal is connected, wait for 10 seconds or more to 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.
