Disconnect the negative battery cable

Disconnecting the negative battery cable is one of the first steps to take when relieving the fuel system pressure of a 2006 Suzuki Aerio. This is a crucial step to ensure your safety when working on the fuel system and should be done before draining the fuel tank.

To disconnect the negative battery cable, you will need to locate the battery in the engine bay. The negative battery cable is typically black and is connected to the negative terminal of the battery, which is also usually marked with a "-" symbol or black cover. Once located, you will need to loosen the nut or bolt securing the cable to the terminal using a suitable wrench or socket. Be careful not to let the wrench or socket touch any other parts of the car, as this could result in an electrical short. After the nut or bolt is loosened, carefully remove the cable from the terminal.

It is important to note that you should always disconnect the negative cable first when working on a car's electrical system. This is because if the positive cable is disconnected first, the car's entire electrical system will still be live, which can be dangerous. Additionally, always make sure to wear protective gear, such as gloves and eye protection, when working on your car's battery.

Once the negative battery cable is disconnected, you can proceed with the next steps of relieving the fuel system pressure, such as draining the fuel tank and removing the fuel pump. These steps should be performed by a professional mechanic, as they involve dealing with gasoline, which is highly flammable.
