### Removal Procedure

1. Record all of the vehicle preset radio stations (if applicable). Refer to Radio/Audio System Operation in Entertainment.
2. Turn off all the lamps and accessories.
3. Turn the ignition OFF.

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

4. Remove the negative battery ground cable and bolt from the battery.

### Installation Procedure

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

Important: Clean any existing corrosion from the battery terminal bolt flange and the battery cable end.

1. Install the negative battery ground cable and bolt to the battery.
