Answer
REMOVAL
The battery cables on this model may include portions of wiring circuits for the generator and other components on the vehicle. If battery cable replacement is required, it will be necessary to extract the cables out of the engine wire harness assembly. Use care not to damage the other wires and circuits which are also packaged into the engine wire harness assembly.

Turn the ignition switch to the Off position. Be certain that all electrical accessories are turned off.
Disconnect and isolate the negative battery cable terminal.
Remove the battery thermowrap (if equipped) from the battery tray.
Remove the tape from the engine wire harness assembly, to access the desired battery cable.
One at a time, trace and disconnect the battery cable retaining fasteners and routing clips until the desired cable is free from the vehicle.
Feed the battery cable out of the vehicle.
