2. Unfasten the battery hold-down bracket using a socket set.
3. Carefully lift the old battery out of the tray.
4. Place the new battery into the tray, ensuring it is secure.
5. Reconnect the positive terminal first, then the negative terminal.
6. Ensure all connections are tight and free of corrosion.

3. Starter Motor Inspection (if battery is not the issue)

Sub-steps:
1. Disconnect the negative battery terminal again.
2. Locate and remove the starter motor from the engine (may require removing heat shields).
3. Inspect the starter for any visible damage or wear.
4. Use a multimeter to check for continuity in the starter solenoid.
5. If defective, replace the starter motor with a new one.
6. Reinstall the starter motor and reconnect the battery.

4. Check Wiring and Connections
