Solution

1. Preparation

Tools Required:
- Socket set (including 10mm socket)
- Torque wrench
- Battery terminal cleaner
- Safety gloves and goggles
Ensure the vehicle is parked on a level surface with the engine turned off.
Disconnect the vehicle's key fob to prevent accidental activation of accessories.

2. Disconnect the Old Battery

Open the trunk and locate the battery compartment on the right side.
Remove the cover, if applicable, by unscrewing any fasteners.
Using the 10mm socket, disconnect the negative terminal first (black cable) to prevent a short circuit.
Next, disconnect the positive terminal (red cable).
Remove any hold-down brackets securing the battery using the socket set.

3. Remove and Replace the Battery

Carefully lift the old battery out of the compartment (batteries can be heavy; consider assistance if needed).
Clean the battery tray and terminals with a battery terminal cleaner to remove any corrosion.
Place the new battery in the tray, ensuring the terminals are positioned correctly (positive to positive, negative to negative).

4. Connect the New Battery

Reinstall the hold-down brackets to secure the battery in place, tightening them to the manufacturer's specifications (typically around 8-10 Nm).
Connect the positive terminal first (red cable), followed by the negative terminal (black cable).
Ensure all connections are tight to prevent any electrical issues.

5. Final Checks

Replace the battery cover securely.
Reconnect the vehicle’s key fob and check for any warning lights on the dashboard.
Dispose of the old battery at a certified recycling center.
