Disconnection
Note. Some systems store data in memory that is lost when the battery is disconnected. Do the following steps before disconnecting the battery.
- Make sure you have the anti-theft code(s) for the audio and/or the navigation system (if equipped).
- If you are replacing the audio unit, write down the audio presets (AM and FM), and the XM audio preset (if equipped), because the audio unit does not retain the preset after the battery is disconnected.
- Make sure the ignition switch is in LOCK (0).
- Disconnect and isolate the negative cable from the battery. NOTE: Always disconnect the negative cable from the battery first.
- Disconnect the positive cable from the battery.
Reconnection
Note. Some systems store data in memory that is lost when the battery is disconnected. Do the following procedures to restore the systems back to normal operation.
Scheme 7
- Clean the battery terminals.
- Test the battery (see BATTERY TEST ).
- 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.
- Apply multipurpose grease to the terminals to prevent corrosion.
- Enter the anti-theft code(s) for the audio system and/or the navigation system (if equipped).
- Enter the audio presets (if applicable), and enter the XM audio presets (if equipped).
- Set the clock (for vehicles without navigation).
Note. The battery terminal disconnection/reconnection procedure (see BATTERY TERMINAL DISCONNECTION AND RECONNECTION ) must be done before and after doing this procedure. Some systems store data in memory that is lost when the battery is disconnected.
Scheme 8
- Do the battery terminal disconnection procedure (see BATTERY TERMINAL DISCONNECTION AND RECONNECTION ).
- Remove the two nuts (A) securing the battery setting plate, then remove the battery setting plate (B) and the battery (C).
Scheme 9
- Install the battery (A), then install the battery setting plate (B).
- Tighten the two nuts (C) equally until the battery is stable. NOTE: Do not deform the battery setting plate by tightening the nuts too much.
- Do the battery terminal reconnection procedure (see BATTERY TERMINAL DISCONNECTION AND RECONNECTION ). NOTE: Make sure the battery is installed correctly, and the positive terminal and the negative terminal are not connected in reverse.
