Hello. I am new to the Rav4 family. I just purchased a 2014 Rav4 XSE Hybrid and love it. I am almost at 400 miles. My fuel gauge was almost at empty ( not quite for warning light to go on) until this afternoon.. When I started my car again recently , now the fuel gauge says there is a little over a 1/4 tank left. I am new to hybrids and how they work. Is this normal for the fuel gauge to adjust itself? Why does it do this ?
