How to Set the Lock Car Horn Sound for Volvo?

[LaJames]

Volvo setting the lock car horn sound steps are as follows: 1. Press the brake pedal and push the gear shift to the P position and hold it. 2. Release the brake pedal, then rotate the one-button start key twice in succession. 3. After closing all four doors, press and hold the lock button on the driver's side door for more than 10 seconds, and the lock car horn sound setting is completed. Here is more information about the lock car horn: 1. The lock car horn mainly emits sound through electromagnetic vibration. The electromagnetic coil attracts the moving contact switch of the relay to close, in which case the current will flow to the horn wiring. The current causes the electromagnet inside the horn to work, thereby vibrating the diaphragm to produce sound, so the sound is emitted when the car is locked. 2. The horn reminder when the car is locked is part of the car's anti-theft system. For the safety of the car, it is recommended not to eliminate it.
