⚠️ Safety & Precautions

• ⚠️ Wear eye protection; batteries can vent acid and gas.
• ⚠️ Key OFF, remove key/fob from the truck, and wait 2 minutes before disconnecting (lets modules go to sleep).
• ⚠️ Disconnect negative (-) first and reconnect it last to reduce short-circuit risk.
• ⚠️ Do not let a tool touch the positive terminal and metal body parts at the same time.
• ⚠️ No battery disconnect is strictly required beyond removing cables, but keep doors closed and lights off to reduce electrical load.

🔨 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 there’s a cover or intake ducting blocking access, release clips with a small flat-blade screwdriver and move it aside.

Step 2: Disconnect the negative (-) cable

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

Step 3: Disconnect the positive (+) cable

• Use a 10mm socket to loosen the positive terminal clamp.
• Remove the cable and position it so it can’t touch metal parts.

Step 4: Remove the battery hold-down

• Find the battery hold-down clamp at the base of the battery.
• Use a 13mm socket, 6" extension, and 3/8" ratchet to remove the hold-down bolt and clamp.

Step 5: Remove the old battery

• Wearing nitrile gloves, lift the battery straight up and out.
• Batteries are heavy; keep your back straight and lift with your legs.

Step 6: Clean and prep the connections

• Use a battery terminal brush to clean corrosion from the cable clamps.
• If you’re installing felt washers, slide on anti-corrosion felt battery terminal washers now.
• Lightly coat the posts/clamps with dielectric grease (thin film only).

Step 7: Install the new battery

• Set the new battery into the tray in the same orientation as the old one.
• Reinstall the hold-down clamp and bolt using a 13mm socket.
• Tighten with a torque wrench: Torque to 9 Nm (80 in-lbs).

Step 8: Reconnect the positive (+) cable

• Install the positive clamp onto the positive post.
• Use a 10mm socket to tighten.
• Tighten with a torque wrench: Torque to 15 Nm (11 ft-lbs).

Step 9: Reconnect the negative (-) cable

• Install the negative clamp onto the negative post.
• Use a 10mm socket to tighten.
• Tighten with a torque wrench: Torque to 15 Nm (11 ft-lbs).

Step 10: Protect and reassemble

• Spray terminals with battery terminal protectant spray.
• Reinstall any covers/ducts you moved using the small flat-blade screwdriver as needed for clips.

✅ After Repair

• Start your Canyon and confirm it cranks normally and the charging system light is off.
• Check that headlights, horn, and HVAC blower work normally.
• If power windows lost “auto” function: raise the window fully, hold the switch up for 3 seconds, then lower fully and hold for 3 seconds.
• If the check engine light appears after battery replacement, recheck terminal tightness and cleanliness, then scan for codes if it stays on.
