⚠️ Safety & Precautions

• ⚠️ Turn the car OFF, remove the key, and keep it away from the vehicle.
• ⚠️ Wear eye protection and gloves—battery acid is corrosive.
• ⚠️ Never let a tool touch both battery terminals at the same time.
• ⚠️ Disconnect negative (-) first, reconnect negative (-) last to reduce short-circuit risk.
• ⚠️ Do not smoke or create sparks near the battery.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the battery and remove any covers

• Open the hood and find the battery in the engine bay.
• If equipped, remove any battery cover by hand or with a 10mm socket.

Step 2: Disconnect the negative (-) terminal first

• Use a 10mm socket (or 10mm combination wrench) to loosen the negative terminal clamp nut.
• Twist the clamp gently and lift it off the negative post.
• Move the cable aside so it cannot spring back onto the battery.

Step 3: Disconnect the positive (+) terminal

• Use a 10mm socket to loosen the positive terminal clamp nut.
• Lift the clamp off the positive post and position it safely away from the battery.

Step 4: Remove the battery hold-down

• Use a 12mm socket, 3/8" ratchet, and 6" extension to remove the hold-down bolt(s).
• Lift out the hold-down bracket and set it aside.
• Torque on install: Torque to 18-22 Nm (13-16 ft-lbs)

Step 5: Remove the old battery

• Lift the battery straight up and out. Batteries are heavy—use both hands.
• Keep it upright to avoid leaking electrolyte.

Step 6: Clean the battery tray and terminals

• Inspect the tray for corrosion. Clean debris and moisture.
• Use a battery terminal cleaning brush to clean the inside of each cable clamp until the metal looks bright.
• If a clamp is stuck, use a battery terminal puller (specialty) (a small tool that presses the clamp off without prying).

Step 7: Install the new battery and secure it

• Place the new battery into the tray in the same orientation as the old one.
• Reinstall the hold-down bracket using a 12mm socket, 3/8" ratchet, and 6" extension.
• Torque: Torque to 18-22 Nm (13-16 ft-lbs)

Step 8: Reconnect the positive (+) terminal first

• Install anti-corrosion washers if you’re using them.
• Push the positive clamp fully down onto the positive post.
• Use a 10mm socket to tighten the clamp nut.
• Torque: Torque to 5-7 Nm (44-62 in-lbs)
• Apply battery terminal protectant spray after tightening.

Step 9: Reconnect the negative (-) terminal last

• Push the negative clamp fully down onto the negative post.
• Use a 10mm socket to tighten the clamp nut.
• Torque: Torque to 5-7 Nm (44-62 in-lbs)
• Apply battery terminal protectant spray after tightening.

Step 10: Quick battery check

• Use a digital multimeter across the battery posts.
• Engine OFF: you should typically see about 12.4-12.7V on a healthy fully charged battery.
• Start the engine and recheck: charging voltage is typically about 13.5-14.7V.

✅ After Repair

• Start the engine and confirm the crank is strong and steady.
• Reset the clock and radio presets as needed.
• If the auto-up window function stops working: raise each window fully and keep holding the switch up for 2-3 seconds to re-learn.
• Watch for warning lights; if one stays on, recheck that both battery clamps are tight and fully seated.
