Where is the fuel tank cap switch located on the old Jetta?

[SanMolly]

The old Jetta's fuel tank cap does not have a switch; it is opened with a key. The fuel tank cap is located on the passenger side. After turning off the engine, use the key to locate the fuel tank cap, insert the key into the hole, hold the cap with your left hand, and turn the key to the left with your right hand, then twist the cap to open it. After refueling, screw the cap back on clockwise until you hear a "click," indicating it is properly secured, then simply press the fuel tank cap back into place. There are three common methods to open a car's fuel tank cap: 1. Press-to-open type; 2. Switch button type; 3. Mechanical key type. Taking the press-to-open type as an example: When the vehicle is unlocked, simply press the fuel tank cap with your hand to open it. Note that the fuel tank cap must be opened when the car is in the unlocked state.
