2. Remove Old Battery

Open the hood and locate the battery.
Remove the negative terminal (black cable) first using a socket wrench.
- Sub-step: Loosen the bolt on the terminal clamp and gently wiggle the connector off.
Remove the positive terminal (red cable) using the socket wrench.
If equipped, remove any battery hold-down clamp using the socket wrench.
