10th-generation Civic has a horn sound when locking the car. Here are the relevant details: 1. Method to activate the locking horn sound: Use the remote key to enable the locking horn by simultaneously pressing the unlock and lock buttons for 3 seconds. The successful activation is indicated by flashing lights. 2. The horn cannot be rigidly mounted; it must be fixed on a buffer bracket, meaning a leaf spring or rubber pad should be installed between the horn and the fixed bracket. 3. Air horns are mainly used in heavy-duty trucks with air brake systems, while electric horns are widely used in small and medium-sized vehicles due to their simple structure, compact size, lightweight, pleasant sound, and easy maintenance.
