• ⚠️ The seat contains airbag wiring; do not unplug any yellow connectors.
• ⚠️ The battery is heavy—lift with legs, not your back.
• ⚠️ Battery disconnect is required for this job.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the battery under the passenger seat

• Slide the front passenger seat all the way back using the seat switch.
• Use a trim removal tool to lift the door-sill scuff plate edge enough to free the carpet if needed.
• Fold back the carpet to expose the battery access cover.
• Use a 10mm socket and 3/8" ratchet to remove the access cover fasteners (if equipped), then remove the cover.
• Work slowly to avoid cracking trim.

Step 2: Disconnect the battery (negative first)

• Use a 10mm socket to loosen the negative (-) terminal clamp and remove it from the battery post.
• Move the negative cable aside so it cannot spring back onto the post.
• Use a 10mm socket to loosen the positive (+) terminal clamp and remove it from the battery post.
• If a small vent tube is attached to the battery, pull it off by hand (do not tear it).
• Torque to 6 Nm (53 in-lbs) for the terminal clamp nuts during reassembly.

Step 3: Remove the battery hold-down and lift out the battery

• Use a 13mm socket, 3/8" ratchet, and 3" socket extension to remove the battery hold-down bolt and bracket.
• Lift the battery straight up and out.
• Torque to 20 Nm (15 ft-lbs) for the battery hold-down bolt during reassembly.
• Keep the battery upright to prevent leaks.

Step 4: Install the new battery

• Set the new battery into the tray in the same orientation as the old one.
• Reinstall the hold-down bracket and bolt using a 13mm socket.
• Reconnect the vent tube if your battery uses one.
• Torque to 20 Nm (15 ft-lbs) for the battery hold-down bolt.

Step 5: Reconnect terminals (positive first)

• Install anti-corrosion washers (optional) on the posts.
• Reconnect the positive (+) terminal first and tighten using a 10mm socket.
• Reconnect the negative (-) terminal last and tighten using a 10mm socket.
• Torque to 6 Nm (53 in-lbs) for the terminal clamp nuts.
• Apply battery terminal protectant spray after everything is tight.

Step 6: Reinstall the access cover and carpet

• Reinstall the battery access cover and fasteners using a 10mm socket.
• Fold the carpet back into place and press trim back down by hand.

Step 7: If you removed the passenger seat bolts (only if necessary)

• Use an E14 external Torx socket and torque wrench to reinstall seat mounting bolts.
• Torque to 47 Nm (35 ft-lbs) for the seat mounting bolts.
• Never unplug yellow airbag connectors.
