📋 Before You Begin

• Park on level ground, shift to Park, and set the parking brake.
• Open the hood and let the vehicle sit for 5 minutes so modules go to sleep.
• If you want to preserve settings, you can use a memory saver (optional). If you don’t have one, your clock and radio presets may reset.
• Have a safe place ready to set the old battery (upright, stable, away from kids/pets).

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the battery

• Open the hood and locate the battery in the engine compartment.
• If a cover or air duct is blocking access, remove fasteners using a 10mm socket or release clips using a trim clip tool.
• Take a quick photo before disassembly.

Step 2: Disconnect the negative (–) battery cable

• Use a 10mm socket to loosen the negative terminal clamp nut.
• Twist and lift the clamp off the battery post. If it’s stuck, use a battery terminal puller (specialty) (this tool pulls the clamp off without damaging it).
• Tuck the negative cable aside so it cannot spring back and touch the post.
• Torque to 15 Nm (11 ft-lbs) when reinstalling.

Step 3: Disconnect the positive (+) battery cable

• Use a 10mm socket to loosen the positive terminal clamp nut.
• Remove the clamp from the post and move it aside.
• Torque to 15 Nm (11 ft-lbs) when reinstalling.

Step 4: Remove the battery hold-down

• Locate the battery hold-down at the battery base.
• Use a 13mm socket, 6" extension, and 3/8" ratchet to remove the hold-down bolt and bracket.
• Torque to 25 Nm (18 ft-lbs) when reinstalling.

Step 5: Remove the old battery

• Use a battery carrying strap and lift the battery straight up and out.
• Set it down upright. Batteries are heavy—lift with your legs, not your back.

Step 6: Clean and prep the terminals

• Use a wire brush battery terminal cleaner to clean any white/green corrosion from the cable clamps.
• Install battery terminal felt washers if you’re using them.

Step 7: Install the new battery

• Place 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, extension, and ratchet.
• Finish tightening with a torque wrench: Torque to 25 Nm (18 ft-lbs).

Step 8: Reconnect cables (positive first, negative last)

• Reconnect the positive (+) cable first and tighten using a 10mm socket, then torque wrench: Torque to 15 Nm (11 ft-lbs).
• Reconnect the negative (–) cable last and tighten using a 10mm socket, then torque wrench: Torque to 15 Nm (11 ft-lbs).
• Apply battery terminal anti-corrosion spray to the terminals.

Step 9: Reinstall any covers/ducting

• Reinstall anything you removed using a 10mm socket and/or trim clip tool.
• Double-check nothing is left loose near the belt/fans.

✅ After Repair

• Check that headlights and interior electronics work normally.
• Set the clock and re-save radio presets if they reset.
• If you see a warning message after reconnecting, drive for 5–10 minutes; many modules relearn after a short drive.
