⚠️ Safety & Precautions

• ⚠️ Turn the ignition OFF, remove the key, and keep it away from the car while working.
• ⚠️ Wear eye protection and gloves; batteries contain acid and can spark.
• ⚠️ Always disconnect the negative (-) terminal 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 is heavy—lift with both hands and keep it upright.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the battery and clear access

• Open the hood and locate the battery in the engine bay (driver-side front area).
• If a cover is present, remove it by hand (some covers lift straight up).

Step 2: Disconnect the negative (-) cable

• Use a 10mm socket with a 3/8" ratchet to loosen the nut on the negative (-) terminal.
• Twist and lift the clamp off the post. If it’s stuck, use a battery terminal puller (specialty) (this tool presses the clamp off without prying).
• Tuck the negative cable to the side so it can’t spring back onto the battery post.
• Torque to 9 Nm (80 in-lb) when reinstalling this terminal.

Step 3: Disconnect the positive (+) cable

• Use a 10mm socket to loosen the nut on the positive (+) terminal.
• Lift the clamp off the post and move it aside so it cannot touch metal.
• Torque to 9 Nm (80 in-lb) when reinstalling this terminal.

Step 4: Remove the battery hold-down

• Locate the battery hold-down clamp at the base of the battery.
• Use a 13mm socket with a 3/8" ratchet and 6" extension to remove the hold-down bolt.
• Remove the clamp and set it aside.
• Torque to 20 Nm (15 ft-lb) when reinstalling the hold-down bolt.

Step 5: Remove the old battery

• Lift the battery straight up and out (keep it upright).
• Set it on the ground in a safe spot.

Step 6: Clean the terminals and tray

• Use a battery terminal cleaning brush (specialty) to lightly clean the inside of both cable clamps.
• If there’s corrosion (white/blue crust), brush until the metal looks clean.
• Wipe the battery tray area clean with a dry rag (don’t use water around open terminals).
• Tip: Clean metal = better charging and starting.

Step 7: Install the new battery

• Place the new battery into the tray in the same orientation as the old one (posts in the same positions).
• Reinstall the hold-down clamp using the 13mm socket.
• Torque to 20 Nm (15 ft-lb).

Step 8: Reconnect the positive (+) cable first

• Install the positive clamp onto the positive post.
• Use a 10mm socket to tighten the terminal.
• Torque to 9 Nm (80 in-lb).
• Install battery terminal anti-corrosion pads (one per post) if you’re using them.

Step 9: Reconnect the negative (-) cable last

• Install the negative clamp onto the negative post.
• Use a 10mm socket to tighten the terminal.
• Torque to 9 Nm (80 in-lb).
• Apply battery terminal protectant spray after everything is tightened.

✅ After Repair

• Start the engine and confirm it cranks normally and idles smoothly.
• Check that the battery is secure (it should not move when you push it by hand).
• Reset the clock and radio presets if they were lost.
• If the idle is slightly rough at first, let it idle for a few minutes with all accessories OFF (normal after battery disconnect).
