Remove the battery.
Disconnect the battery terminals (A).
Tightening torque
(+) terminal :
7.8 ~ 9.8 N.m (0.8 ~ 1.0 kgf.m, 5.8 ~ 7.2 lb-ft)
(-) terminal (without battery sensor) :
7.8 ~ 9.8N.m (0.8 ~ 1.0kgf.m, 5.8 ~ 7.2lb-ft)
(-) terminal (with battery sensor) :
3.9 ~ 5.9N.m (0.4 ~ 0.6kgf.m, 3.0 ~ 4.4lb-ft)
Remove the air duct and air cleaner assembly. (Refer to EM group).
Remove the battery insulation pad (A).
Remove the battery (B) after removing the mounting bracket.
Tightening torque :
9.8 ~ 14.7 N.m (1.0 ~ 1.5 kgf.m, 7.2 ~ 10.8 Ib-ft)
Remove the ECM (B) and the battery tray (C) after disconnecting the ECM connector (A).
Tightening torque
ECM bracket bolts & nut :
9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)
Battery tray bolts :
9.8 ~ 14.7 N.m (1.0 ~ 1.5 kgf.m, 7.2 ~ 10.8 Ib-ft)
Installation is the reverse order of removal.
When installing the battery, fix the mounting bracket on the tray correctly.
ISG (Idle stop & go) system equipped vehicle always use the AGM battery only. If flooded battery has installed, this can potentially lead to engine electrical trouble or ISG system error.
Replace same capacity of the AGM battery.
Ensure an AGM battery is fitted.
In all cases, an AGM battery must be installed and registered in the vehicle for the ISG function to work perfectly.
The vehicle with the new battery must be placed in the ignition switch OFF and door closed, hood switch OFF state for at least 4 hours.
ISG system’s stabilization may take 4 hours after new battery installation.
ISG function is operates about 4 hours later and 2 times cranking by user.
But first 25 times, the ISG function can operates regardless of ISG system stability for ISG function operating check.
Do not open the AGM battery.
The AGM battery must not be opened under any circumstances as the introduction of oxygen from the air will cause the battery to lose its chemical equilibrium and rendered non-operational.
