* Some vehicles have no dedicated emergency brake switch. The emergency brake (parking brake) is purely mechanical, and there's no electrical switch involved.
* In vehicles with electronic parking brakes (EPB), the switch is usually integrated into the parking brake control itself. This might be a button, a lever, or a switch located near the gear shifter or center console. The exact location will depend on the make and model of the vehicle.
* In some vehicles with an EPB, there might also be a switch related to emergency brake operation located within the vehicle's control modules – this is *not* something accessible to the driver for direct use.
To find it, you need to consult your vehicle's owner's manual. The manual will have a diagram showing the location of all controls, including any emergency brake switches. If you don't have a manual, you can usually find a digital version online by searching for "[Your Vehicle Make and Model] owner's manual".
