The location of the emergency shut-off switch will vary depending on the model of your Ford Ranger. Please consult with the owner's manual for the specific location of the emergency shut-off switch for your vehicle.
Once you have located the emergency shut-off switch, you can reset it by following these steps:
1. Turn the ignition to the "off" position.
2. Press down on the emergency shut-off switch and release it.
3. Try to start the vehicle.
The vehicle will start normally if the switch has been successfully reset. If the switch does not reset, it is important to take the vehicle to a dealership or qualified mechanic to have it inspected.
