Caution: Before servicing any electrical component, the ignition and start switch must be in the OFF or LOCK position and all electrical loads must be OFF, unless instructed otherwise in these procedures. If a tool or equipment could easily come in contact with a live exposed electrical terminal, also disconnect the negative battery cable. Failure to follow these precautions may cause personal injury and/or damage to the vehicle or its components.

Caution: This vehicle is equipped with a Supplemental Inflatable Restraint (SIR) System. Failure to follow the correct procedure could cause the following conditions:

1. Disconnect the battery ground (negative) cable from the battery. Refer to Battery Negative Cable Disconnection and Connection .
2. Remove the front end sheet metal diagonal brace. Refer to Front Fender Upper Diagonal Brace Replacement in Body Front End.
3. Disconnect the battery (positive) cable from the battery.
4. Remove the battery hold down retainer.
5. 3800 only. Place the underhood accessory wiring junction block aside for access to the battery. Refer to Accessory Wiring Junction Block Replacement in Body Front End.

Important: Do not tip the battery more than 40 degrees during removal.

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.
