🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate and inspect the battery

• Put on the safety glasses and acid-resistant work gloves.
• Locate the battery on the driver’s side of the engine compartment.
• Check for a cracked case, leaking fluid, or badly swollen sides. Do not handle a leaking or frozen battery; have it professionally removed.

Step 2: Disconnect the negative cable

• Use the 10mm socket and 3/8-inch-drive ratchet to loosen the negative terminal clamp marked “−”.
• Twist the clamp gently and lift it straight off the battery post. Do not pull on the cable or strike the battery sensor.
• Move the cable aside where it cannot spring back onto the post.
• Negative comes off first and goes on last.

Step 3: Disconnect the positive cable

• Open the red positive-terminal cover.
• Use the 10mm socket and 3/8-inch-drive ratchet to loosen the positive terminal clamp marked “+”.
• Lift the clamp straight off and position it away from the battery post.
• Keep the ratchet from contacting body metal while it touches the positive clamp.

Step 4: Remove the battery hold-down

• Use the 10mm socket, 3/8-inch-drive 6-inch extension, and 3/8-inch-drive ratchet to loosen the two hold-down nuts evenly.
• Unhook the hold-down rods and remove the upper bracket. A hold-down is the bar that prevents the battery from moving.
• Place the bracket and rods where they cannot fall into the engine compartment.

Step 5: Remove the old battery

• Attach the battery carrier strap securely. This strap grips the battery and provides safer lifting handles.
• Lift the battery straight upward without tipping it. Keep it upright because liquid electrolyte may be present inside.
• Place it upright on a stable surface away from children and pets.

Step 6: Clean and inspect the mounting area

• Use the plastic trim brush to remove dry dirt and debris from the battery tray.
• Use the battery terminal cleaning brush to clean corrosion from the cable clamps.
• Inspect the tray, hold-down rods, cables, and clamps for damage. Replace damaged hardware before installing the battery.

Step 7: Install the replacement battery

• Use the battery carrier strap to lower the Group 24F battery into the tray with the terminals facing the same direction as the original battery.
• Make sure the battery sits flat and does not trap either cable underneath it.
• Remove the carrier strap after the battery is fully seated.

Step 8: Install the hold-down bracket

• Position the upper bracket and engage both hold-down rods correctly in the battery tray.
• Use the 10mm socket, 3/8-inch-drive 6-inch extension, and 3/8-inch-drive inch-pound torque wrench to tighten the nuts evenly.
• Torque the battery hold-down nuts to 4.4 Nm (39 in-lbs).
• Check that the battery cannot slide or rock. Do not overtighten the bracket because the battery case can crack.

Step 9: Connect the positive cable

• Push the positive clamp completely down onto the positive post.
• Use the 10mm socket and 3/8-inch-drive inch-pound torque wrench to tighten the clamp nut.
• Torque the positive terminal nut to 6 Nm (53 in-lbs).
• Apply a light coating of battery terminal protectant spray around the outside of the connected clamp. Do not spray between the post and clamp.
• Close the red positive-terminal cover.

Step 10: Connect the negative cable

• Push the negative clamp completely down onto the negative post without twisting or stressing the battery sensor.
• Use the 10mm socket and 3/8-inch-drive inch-pound torque wrench to tighten the clamp nut.
• Torque the negative terminal nut to 6 Nm (53 in-lbs).
• Apply a light coating of battery terminal protectant spray around the outside of the connected clamp.

Step 11: Restore the driver’s window auto function

• Start the engine and close the driver’s door.
• Use the driver’s window switch to lower the window completely.
• Pull the switch upward until the window closes completely, then continue holding it for at least two seconds.
• Check that one-touch automatic lowering and closing work normally.

✅ After Repair

• ✅ Start the engine and verify that it cranks normally.

• 🧪 Switch on the headlights and climate-control blower to verify stable electrical operation.
• 🕒 Reset the clock, audio presets, and other personalized settings if they were erased.
• 🚗 Turn the steering wheel from center to near full left and right, then take a short drive if stability-system warning lights remain illuminated. They should clear after the systems relearn.
• ♻️ Return the old battery upright to a battery retailer or authorized recycler. Do not place it in household trash.
