Why does the Focus's red light flash and fail to start?

Anti-theft system activation: When the anti-theft system is activated, the engine will not function normally and remains in a locked state. Location of the hazard warning lights: The hazard warning light button is located in the center of the dashboard, featuring a red triangle symbol. Pressing this button activates all four turn signals to flash simultaneously. Hazard warning lights, commonly known as 'double flashers,' are technically referred to as emergency warning lights. Reason for not using hazard lights in heavy fog: Since hazard lights represent the highest level of warning signal, many drivers instinctively turn them on during heavy fog. However, this practice is prohibited in some countries because it makes it difficult for following vehicles to determine the leading vehicle's intended direction.
