Using these floor liners is a breeze. First, just unpack them and place them in the footwells of your 2005 - 2009 Subaru Legacy GT or Outback XT. They are designed to fit perfectly due to the laser - measured dimensions. Make sure to engage the specially designed retention system to keep them firmly in place. When it comes to maintenance, if there are any fluids or debris in the lower reservoir, simply lift the liner over the door sill and empty it. For a more thorough clean, you can use mild soap and water. Avoid using harsh chemicals as they may damage the high - density material. Also, during installation, take your time to ensure the liners are properly aligned with the footwell contours for the best protection.
