Where is the fuel filler cap switch on the BMW 535?

The BMW 5 Series actually does not have a fuel filler cap switch inside the car; the switch is located on the exterior. To open the fuel tank, you first need to open the fuel filler cap, which is on the passenger side. If you want to refuel, align the right side with the fuel dispenser. With the engine off, gently press the fuel filler cap, and it will pop open. No Smoking: "No open flames" is a common warning seen at gas stations. For those who have the habit of smoking a cigarette while parked, this habit must not be carried over to the gas station. This is because the concentration of gasoline in the unit space increases during refueling, and an open flame could potentially ignite the gasoline. No Phone Calls: Gas stations usually post prominent signs prohibiting the use of mobile phones. Occasionally, if a driver is seen using a phone at the gas station, staff will immediately intervene to stop them.
