Using a socket set, loosen the negative terminal clamp and remove it first.
Then, loosen and remove the positive terminal clamp.
If applicable, use a torque wrench to ensure proper tightness upon reconnection.

Connect the positive terminal first and tighten securely.
Connect the negative terminal and tighten securely.
If the battery has a hold-down bracket, reattach it using the appropriate tools.

4. Resetting Systems

Start the vehicle and let it idle for approximately 5 minutes.
Use the OBD-II scanner to check for any error codes and clear them if necessary.
Manually reset the radio, seats, and mirrors to their preferred settings as they may have reverted to factory defaults.
