Safe Disconnect Of The 12V Battery - Kia Optima Hybrid Emergency Response Manual

Emergency Procedures
3.2.1 Safe Disconnect of the 12 Volt Battery
The 12V auxiliary battery is located in the trunk of the vehicle, in the right side of the luggage
compartment, and powers all of the vehicle's standard electronics. There is a cover over the
12V DC battery that is simply removed to access the battery.
The battery is maintenance-free, which means it has no removable cell caps. Callout A in the
drawing above marks the Positive Battery Terminal, Callout B marks the Negative Battery
Terminal, and Callout C marks the Vent Hose, which vents to the outside by the right rear
wheel well.
When disconnecting the 12V battery, disconnect the Negative Terminal first.
Before disconnecting the 12V battery (if needed) lower the windows, unlock the doors and
open the trunk as required. Once the 12V battery is disconnected, power controls will not
operate.
