⚠️ Safety & Precautions

• Wear safety glasses and gloves. A battery contains corrosive acid and can produce flammable gas.
• Switch off the ignition, lights, fan, and all accessories before disconnecting the battery.
• Always disconnect the negative terminal first and reconnect it last. This reduces the chance of an electrical short.
• Do not let a tool touch the positive terminal and any metal body component simultaneously.
• Keep sparks, cigarettes, and open flames away from the battery.
• The battery is heavy. Lift it upright with both hands and do not tip it.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate and inspect the battery

• Open the hood and locate the battery on the driver’s side of the engine compartment.
• Put on the safety glasses and nitrile gloves before touching the battery.
• Look for swelling, cracks, or leaking fluid. If the case is damaged, do not tilt or handle it without professional assistance.

Step 2: Disconnect the negative terminal

• Identify the negative terminal by its minus symbol and black cable.
• Use the 10mm socket and 3/8-inch-drive ratchet to loosen the negative terminal clamp nut.
• Twist the clamp gently while lifting it from the battery post. Position the cable where it cannot spring back onto the post.
• Negative comes off first and goes on last.

Step 3: Disconnect the positive terminal

• Lift the red protective cover from the positive terminal.
• Use the 10mm socket and 3/8-inch-drive ratchet to loosen the positive terminal clamp nut.
• Lift the positive clamp straight off the post. Do not pull on the cable or disturb the attached fuse assembly.

Step 4: Remove the battery hold-down

• The hold-down is the small bracket securing the lower edge of the battery. It prevents the battery from moving while driving.
• Use the 12mm socket, 6-inch extension, and 3/8-inch-drive ratchet to remove the hold-down bolt and bracket at the base of the battery.
• Place the bolt and bracket somewhere clean so they are not lost.

Step 5: Remove the old battery

• Fit the battery lifting strap securely around the battery.
• Use the lifting strap to raise the battery straight upward with both hands. Keep it upright.
• Set the battery on a stable, acid-resistant surface away from children, flames, and metal objects.

Step 6: Inspect the tray and terminals

• Check the battery tray and hold-down bracket for corrosion, cracks, or loose hardware.
• Use the battery terminal cleaning brush to clean the inside of both cable clamps until the contact surfaces are free of corrosion.
• Do not install the battery if the tray or hold-down cannot secure it firmly.

Step 7: Install the replacement battery

• Use the battery lifting strap to lower the new battery into the tray with the terminals in the same positions as the original battery.
• Make sure the bottom edge of the battery sits fully inside the tray guides.
• Reinstall the lower hold-down bracket and bolt by hand.
• Use the 12mm socket, 6-inch extension, and torque wrench to tighten the hold-down bolt to 8-10 Nm (71-89 in-lbs).
• Confirm the battery cannot slide or rock. Do not overtighten the bracket against the plastic case.

Step 8: Connect the positive terminal

• Push the positive cable clamp fully down onto the positive battery post.
• Use the 10mm socket and torque wrench to tighten the terminal clamp nut to 4-6 Nm (35-53 in-lbs).
• Apply a light coating of battery terminal protectant after the connection is tight.
• Close the red positive-terminal cover.

Step 9: Connect the negative terminal

• Push the negative cable clamp fully down onto the negative battery post.
• Use the 10mm socket and torque wrench to tighten the terminal clamp nut to 4-6 Nm (35-53 in-lbs).
• Apply a light coating of battery terminal protectant after the connection is tight.
• Check both clamps by hand. Neither clamp should rotate on its post.

✅ After Repair

• Set the clock and restore any radio presets that were lost.
• Confirm the windows, locks, lights, and audio system operate correctly.
• Turn the steering wheel slowly from center toward each side if the electronic steering warning remains illuminated after startup. The warning should clear after a short drive.
• Return the old battery to a battery retailer or authorized recycling center. Do not place it in household waste.
• Recheck the battery hold-down and terminal clamps after several days of driving.
