Information
If the fuel filler door cannot be opened because ice has formed around it, lightly tap or press on the door to break the ice and free the door. Do not pry the door open. If necessary, spray an approved de-icer around the door (do not use engine coolant antifreeze) or move the vehicle to a warm place and allow the ice to melt.
