• Check the terminal layout before you disconnect anything.

Step 2: Disconnect the negative terminal

• Use the 10mm socket and ratchet to loosen the negative cable clamp.

Step 4: Remove the battery hold-down

Step 5: Lift out the old battery

• Carefully lift the battery straight up and out of the tray.

Step 6: Clean the tray and terminals

• Wipe the area clean and check that the battery tray is not cracked.

Step 7: Install the new battery

• Set the new battery into the tray in the same orientation as the old one.

• Torque to 9 Nm (80 in-lbs).

Step 8: Reconnect the cables

• Install the positive cable first using the 10mm socket.
• Then install the negative cable using the 10mm socket.
• Make sure both clamps are fully seated and tight.
• Torque to 5 Nm (44 in-lbs) for the terminal clamps.
• Do not overtighten the terminals.

Step 9: Protect the terminals
