The hazard switch in a Perodua Alza is an important safety feature that is designed to alert other drivers on the road when there is a problem with the car or if it is parked on the side of the road. It is typically located on the dashboard or center console and is easily accessible to the driver.

When the hazard switch is activated, it turns on all four turn signal lights at the same time, creating a flashing warning signal that is easily visible to other drivers on the road. This signal indicates that there is a problem with the car, such as a mechanical issue, or that the car is parked on the side of the road.

The hazard switch is typically activated by pressing a button or flipping a switch on the dashboard or center console. Once activated, the hazard lights will continue to flash until the switch is turned off or until the car's battery is drained.
