My 2021 HS 500 has the exact same display as yours. I've been wondering the same thing. Meantime I'm driving around with a gas can in the back. I've been roaming around for about 2 hours now driving at low speeds no more than 3,000 rpms max, 10-12 kms/h. Maybe take a little while longer for the first white light on the fuel guage to go out? I hope its not malfunctioning as I am 45 minutes from my dealer in New Hamburg ON and have no trailer to haul it around.
