Caution: When performing service on or near the SIR components or the SIR wiring, the SIR system must be disabled. Refer to SIR Disabling and Enabling . Failure to observe the correct procedure could cause deployment of the SIR components, personal injury, or unnecessary SIR system repairs.

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.

1. Record all of the vehicle preset radio stations.
2. Record the radio Theftlock® code (if applicable). Refer to Radio/Audio System Description and Operation in Entertainment.
3. Turn OFF all the lamps and the accessories.
4. Make sure the ignition switch is in the OFF position.



5. Disconnect the battery negative cable from the battery.

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 oxidation from the contact face of the battery terminal and battery cable using a wire brush before installing the battery cable to the battery terminal.

1. Connect the battery negative cable to the battery.

Tighten the battery negative terminal bolt to 16 N·m (12 lb ft).

2. Unlock the Theftlock® radio (if applicable).
3. Program the radio stations back into the radio as recorded at the beginning of the procedure.
