New to this forum. I just bought used 2015 GMC Sierra 1500. The fuel gauge is almost down to Empty but there is no light indicator yet. I have read previous older posts and it looks like the Low Fuel light indicator should go on when my GMC has approx 2-3 gallons of fuel left. Just wanting to wait until the Low Fuel indicator goes on before refueling, but don't want to run out of gas and get stranded.
Thanks in advance.
