The fuel filler cap can be opened from inside the vehicle by pulling up on the fuel filler cap release lever located at the front of the floor area on the left side of the vehicle.
Note: If the sunroof does not open due to ice, lightly tap or press on it to break the ice. Do not open the lid by levering. If necessary, apply an approved de-icing agent around it (do not use engine coolant for this purpose), or place the car in a warm place and wait until the ice melts.
Warning:
- Fuel vapors are toxic. Fill the tank only when the engine is not running and make sure that there are no sparks or open flames near the filler neck. If the filler cap needs to be replaced, use only a genuine Hyundai spare part.
- In hot weather, a slight hissing sound may be heard when the cap is opened, which is normal and should not cause concern.
- Open the cap by turning it slowly.
