Warnings

Tools required

Parts

• Positive battery cable × 1 — Use OEM specification

Preparation

1. Ensure the ignition is off and the key fob is outside the vehicle
2. Open the hood and secure it with the prop rod
3. Locate the battery in the engine compartment (driver side)
4. Take note of radio code if applicable, and document window position for relearning
5. Ensure all electrical accessories are turned off

Procedure

1. 1

   Disconnect negative battery terminal
   Using a 10mm socket, loosen the negative (-) battery terminal bolt completely. Remove the negative cable from the battery post and secure it away from the battery terminal to prevent accidental contact.
2. 2

   Disconnect positive battery terminal
   Using a 10mm socket, loosen the positive (+) battery terminal bolt. Remove the positive cable from the battery post. Cover the terminal with a shop towel if needed to prevent accidental grounding.
3. 3

   Remove battery hold-down clamp
   Using a 10mm socket, remove the battery hold-down bolt securing the battery clamp. Remove the clamp and carefully lift the battery out of the tray to access components beneath if necessary. Set the battery aside in a safe location.
4. 4

   Trace and identify cable connections
   Follow the positive battery cable from the battery terminal to identify all connection points. On this vehicle, the positive cable typically connects to the fuse box, starter motor, and may have inline fuse holders. Document the routing path for reinstallation.
5. 5

   Disconnect cable from fuse box and components
   Remove any connector screws or bolts securing the positive cable to the underhood fuse box using appropriate socket sizes. Disconnect any inline connectors by releasing locking tabs. If the cable connects to mounting brackets, remove bracket bolts as necessary.

6. 6

   Remove positive cable from vehicle
   Carefully route the old positive cable out of the engine bay, noting any cable clips or routing guides. Remove all cable securing clips and ties. Inspect the cable path for any additional fasteners that may have been overlooked.
7. 7

   Prepare and route new positive cable
   Compare the new positive cable with the old cable to ensure proper length and connector configuration. Route the new cable through the same path as the original, securing it in all factory clip locations. Ensure the cable does not contact sharp edges or hot engine components.
8. 8

   Connect cable to fuse box and components
   Connect the positive cable to the underhood fuse box and any other connection points. Ensure connectors are fully seated with locking tabs engaged. Install and torque all connector screws and bracket bolts to specification.

10. 10

    Clean and connect positive terminal
    Clean the positive battery terminal post with a wire brush if corrosion is present. Apply a thin coat of dielectric grease to the terminal post. Place the positive cable terminal onto the battery post and install the terminal bolt. Torque the battery terminal bolt to specification. Do not overtighten as the terminal is easily damaged.

Reassembly

1. Ensure all cable connections are tight and properly torqued
2. Verify the positive cable is secured in all factory routing clips and does not contact moving parts or hot surfaces
3. Apply dielectric grease or terminal protector spray to battery terminals to prevent corrosion

Verification

• Turn the ignition to the ON position and verify that dashboard lights illuminate normally
• Start the engine and confirm proper operation with no warning lights related to charging system
• Test electrical accessories including headlights, radio, and power windows to confirm proper function
• Perform power window auto-up/down initialization if required (hold window switch up until fully closed, continue holding for 2 seconds)
• Check for proper alternator charging voltage (13.5-14.5V with engine running)
• Reset radio presets and clock as needed
