⚠️ Safety & Precautions

• ⚠️ Wear eye protection and gloves; battery acid is corrosive.
• ⚠️ Keep sparks/flames away; battery gas can ignite.
• ⚠️ Always disconnect the negative (-) terminal first and reconnect it last to reduce short-circuit risk.
• ⚠️ Don’t let a tool touch the positive terminal and metal body at the same time.
• ⚠️ If the engine was running, let it cool; fans can turn on unexpectedly.

📋 Before You Begin

• Park on level ground, shift to Park, and set the parking brake.
• Open the hood and keep keys away from the vehicle.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the battery

• Open the hood and locate the battery in the engine bay.
• If a plastic cover or air snorkel blocks access, remove it using a trim clip tool for push-clips and a 10mm socket for any small bolts.

Step 2: Disconnect the negative (-) terminal

• Use a 10mm socket to loosen the clamp nut on the negative (-) cable.
• Twist the clamp gently and lift it off the battery post.
• Tuck the cable aside so it can’t spring back onto the post.
• Negative off first prevents accidental shorting.

Step 3: Disconnect the positive (+) terminal

• Use a 10mm socket to loosen the positive (+) clamp nut.
• Lift the clamp off and position it away from the battery.
• If there’s a red protective cap, flip it back over the clamp end.

Step 4: Remove the battery hold-down

• Locate the battery hold-down clamp at the base of the battery.
• Use a 13mm socket, ratchet, and 6" extension to remove the hold-down bolt and clamp.
• Set the clamp/bolt aside where they won’t get lost.

Step 5: Remove the old battery

• Lift the battery straight up and out. Use safe lifting—keep your back straight.
• Place it on the ground upright (never on its side).

Step 6: Clean the tray and terminals

• Use shop rags to wipe out dirt or corrosion in the battery tray.
• Use a battery terminal brush to clean the inside of both cable clamps until the metal looks bright.
• If using felt washers, place them on the new battery posts now.

Step 7: Install the new battery

• Set the new battery into the tray in the same orientation as the old one (posts in the same positions).
• Reinstall the hold-down clamp and bolt using a 13mm socket.
• Tighten with a torque wrench: Torque to 17 Nm (150 in-lb) for the hold-down bolt.

Step 8: Reconnect the positive (+) terminal

• Install the positive clamp onto the positive post.
• Use a 10mm socket to tighten the clamp.
• Tighten with a torque wrench: Torque to 7 Nm (62 in-lb) for the terminal clamp nut.
• Apply battery terminal anti-corrosion spray or grease after tightening.

Step 9: Reconnect the negative (-) terminal

• Install the negative clamp onto the negative post.
• Use a 10mm socket to tighten the clamp.
• Tighten with a torque wrench: Torque to 7 Nm (62 in-lb) for the terminal clamp nut.
• Apply battery terminal anti-corrosion spray or grease after tightening.

Step 10: Reinstall any covers and final check

• Reinstall any battery cover/snorkel you removed using the trim clip tool and 10mm socket.
• Gently try to move the battery by hand; it should not shift.
• Visually confirm clamps are fully seated and not crooked.

✅ After Repair

• Start the engine and confirm the starter cranks strongly.
• Check for warning lights; some may clear after a short drive.
• Reset the clock and radio presets if they were lost.
• If the power windows act “one-touch weird,” run each window fully down and fully up once to relearn.
• Dispose of the old battery properly—parts stores typically accept it for recycling.
