• ⚠️ Do not let a tool touch the battery positive (+) and any metal body parts at the same time.
• ⚠️ Batteries are heavy and contain acid—wear gloves and safety glasses.
• ⚠️ If your Trax has a battery vent tube, reinstall it exactly as found.

📋 Before You Begin

• Park on level ground, shift to Park, and set the parking brake.
• Open the hood and let the engine bay cool if it was just driven.
• If you want to preserve radio presets and clock, use a memory saver (a small device that keeps vehicle power while the battery is removed).
• Make sure all lights are OFF and all doors are closed before disconnecting the battery.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the battery

• Open the hood and locate the battery in the engine bay.
• If there’s a battery cover or intake ducting in the way, gently release clips using a plastic trim tool.

Step 2: Disconnect the negative (-) cable

• Use a 10mm socket with a 3/8" ratchet to loosen the negative terminal clamp.
• Lift the negative cable off the battery post and tuck it aside so it cannot spring back.
• Negative off first prevents accidental shorting.

Step 3: Disconnect the positive (+) cable

• Use a 10mm socket to loosen the positive terminal clamp.
• Lift the positive cable off and position it so it cannot touch metal.

Step 4: Remove the battery hold-down

• At the base of the battery, remove the hold-down bolt using a 13mm socket, 6" extension (3/8"), and 3/8" ratchet.
• Set the hold-down bracket and bolt aside where they won’t get lost.

Step 5: Remove the old battery

• Lift the battery straight up and out (use proper lifting posture—bend your knees).
• If your Trax has a vent tube attached to the battery, carefully remove it before lifting the battery out.

Step 6: Clean the tray and terminals

• Use a battery terminal brush to clean inside the cable clamps until the metal looks bright.
• Wipe the battery tray area clean and remove any debris.

Step 7: Install the new battery

• Place the new battery into the tray in the same orientation as the old one.
• If equipped, reconnect the vent tube to the battery.
• Reinstall the hold-down bracket and bolt using a 13mm socket.
• Tighten the hold-down bolt with a torque wrench (3/8" drive): Torque to 25 Nm (18 ft-lbs).

Step 8: Reconnect the positive (+) cable first

• Install the positive terminal onto the battery post.
• Tighten the terminal clamp bolt using a 10mm socket, then finish with a torque wrench (3/8" drive): Torque to 5 Nm (44 in-lbs).
• Install anti-corrosion felt washers if you’re using them, then apply battery terminal protectant spray.

Step 9: Reconnect the negative (-) cable last

• Install the negative terminal onto the battery post.
• Tighten using a 10mm socket, then torque: Torque to 5 Nm (44 in-lbs).

Step 10: Reinstall any covers/ducts

• Reinstall any battery cover or intake parts you removed, using a plastic trim tool to snap clips in place.
