Open the front bonnet and ensure it is securely supported. Before proceeding with the repair, disconnect the negative terminal of the battery to avoid any warning lights.

Then, remove the screws securing the injector battery (it is the red strap on the engine cover, near the oil cap), take it out of its location, and disconnect the connector by releasing the safety catch. Connect the new injector battery to the electrical socket (ensuring the safety catch is properly engaged), place it back in its location, and tighten the securing screws.

Reconnect the battery and start the engine to check its proper functioning.
