Remove the nozzle from the pump and insert it into the fuel filler opening. Pull the handle inside the nozzle upward to release the gas into your tank. The nozzle may have a trigger-lock feature that holds the handle in place while fueling to prevent having to stand and hold it. Once the tank is full, the gas pump will shut off with a click and gas will stop flowing. If you do not intend to completely fill your tank, you will have to watch the pump to see when you have reached the desired dollar amount of gasoline and then release the handle, or stop the automatic flow by pulling up on the handle to release it. Replace the nozzle back on the pump, reattach your fuel filler cap, shut the fuel filler door and you’re on the road again.
