The floor mats are designed to remain in position and out of reach of the accelerator pedal. The driver side floor mat is held in place by two locator pins and the passenger side is held in place by one.
Make sure that the driver side floor mat is properly placed on the floor so that it does not block the movement of the accelerator pedal.
To remove a floor mat, pull up on the rear of the mat to disconnect it from the locator pins.
To reinstall the floor mats, position the openings in the floor mat over the locator pins and push it down into place.
