⚠️ Safety & Precautions

• ⚠️ Turn ignition OFF, remove the key, and keep it away from the vehicle.
• ⚠️ Wear eye protection and gloves; battery acid is corrosive.
• ⚠️ Always disconnect the negative (-) cable first and reconnect it last to reduce short-circuit risk.
• ⚠️ Do not let a tool touch the battery positive (+) terminal and any metal body part at the same time.
• ⚠️ Battery disconnect is not strictly required for removal (you will be disconnecting it anyway), but do not reconnect until the battery is secured.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the battery

• Open the hood and locate the battery on the driver-side of the engine bay.
• If there’s a plastic battery cover, lift it off by hand.

Step 2: Disconnect the negative (-) battery cable

• Use a 10mm wrench to loosen the negative terminal clamp nut.
• Twist the clamp slightly and lift it off the negative post.
• Tuck the negative cable end to the side so it cannot spring back to the post.
• Negative first prevents accidental sparks.

Step 3: Disconnect the positive (+) battery cable

• Flip open the red protective cap (if equipped).
• Use a 10mm wrench to loosen the positive terminal clamp nut.
• Lift the clamp off the positive post and position it away from the battery.

Step 4: Remove the battery hold-down clamp

• Use a 10mm socket, ratchet (3/8"), and 6" extension (3/8") to remove the hold-down hardware.
• Lift off the hold-down bracket and set it aside.

Step 5: Remove the old battery

• Carefully lift the battery straight up and out. Keep it upright.
• If it’s stuck, use a battery terminal puller (specialty) earlier in Step 2/3 to gently free a tight clamp (a puller is a small screw-tool that pushes the clamp off the post without prying).

Step 6: Clean the battery tray and terminals

• Inspect the tray for corrosion. Wipe it clean with a shop towel (use your nitrile gloves and safety glasses).
• Use a battery post/terminal cleaning brush (specialty) to clean the inside of each cable clamp until the metal looks bright.

Step 7: Install the new battery

• Place the new battery into the tray in the same orientation as the old one (posts positioned the same way).
• Reinstall the hold-down bracket using the 10mm socket, ratchet (3/8"), and 6" extension (3/8").
• Tighten hold-down hardware with a torque wrench (inch-pound): Torque to 13 N·m (115 in-lbf).

Step 8: Reconnect the positive (+) cable

• Install a battery terminal felt washer on the positive post (if included), then set the positive clamp onto the post.
• Use a 10mm wrench to tighten the clamp nut: Torque to 5.4 N·m (48 in-lbf).
• Apply battery terminal anti-corrosion spray or grease to the connection.
• Close the red protective cap (if equipped).

Step 9: Reconnect the negative (-) cable

• Install a battery terminal felt washer on the negative post (if included), then set the negative clamp onto the post.
• Use a 10mm wrench to tighten the clamp nut: Torque to 5.4 N·m (48 in-lbf).
• Apply battery terminal anti-corrosion spray or grease to the connection.

Step 10: Final check

• Grab each terminal by hand and try to rotate it. It should not move.
• Confirm the hold-down bracket is tight and the battery cannot shift.
• Reinstall any battery cover by hand.

✅ After Repair

• Start the engine and confirm it cranks normally.
• Check for warning lights; if any stay on, shut off and re-check tight terminal connections.
• Reset the clock and restore radio presets if needed.
• If idle seems rough for a few minutes, let it idle and relearn.
