Starting with the negative battery terminal, disconnect both cables from the battery terminals. If the stereo in your vehicle is equipped with an anti-theft system, make sure you have the correct activation code before disconnecting the battery. Remove the battery hold-down clamp. To remove the battery, detach the negative and positive cables, remove the hold-down strap nuts and hold-down strap, then carefully lift the battery out. Lift out the battery, but be careful as it's heavy. While the battery is out, inspect the carrier (tray) for corrosion. If you are replacing the battery, make sure to get one that's identical, with the same dimensions, amperage rating, cold cranking rating, etc. Installation is the reverse of removal.
