12 Volt Battery Terminal Disconnection and Reconnection

Disconnection

Some systems store data in memory that is lost when the battery is disconnected. Do the following steps before disconnecting the battery.

1. Make sure you have the anti-theft code(s) for the audio and/or the navigation system (if equipped).

2. If you are replacing the audio unit, write down the audio presets (AM and FM), and the XM audio presets (if equipped), because the audio unit does not retain the presets after the battery is disconnected.

3. Make sure the ignition switch is in LOCK (0).

4. Disconnect and isolate the negative cable from the battery.
NOTE: Always disconnect the negative cable from the battery first.

5. Disconnect the positive cable from the battery.

Reconnection

Some systems store data in memory that is lost when the battery is disconnected. Do the following steps to restore the systems back to normal operation.

1. Clean the battery terminals.

2. Test the battery. Testing and Inspection

3. Reconnect the positive cable (A) to the battery (B) first, then reconnect the negative cable (C) to the battery.
NOTE: Always connect the positive cable to the battery first.

4. Apply multipurpose grease to the terminals to prevent corrosion.

5. Do the start clutch pressure control calibration procedure. Programming and Relearning

6. If the IMA battery level gauge (BAT) displays no segments, start the engine, and hold it between 3,500 rpm and 4,000 rpm without load (in P or N) until the BAT displays at least three segments.

7. Enter the anti-theft code(s) for the audio system and/or the navigation system (if equipped).

8. Enter the audio presets (if applicable), and enter the XM audio presets (if equipped).

9. Set the clock (for vehicles without navigation).
