The interior trim panels are molded plastic and fasten with screws or plastic clips.

Pressure Relief Vent

When all the windows are closed and the ventilation system is on, the addition of outside air to the interior of the vehicle causes a positive pressure within the vehicle. To relieve the pressure, air is released through a pressure relief vent. The pressure relief vents are located at the rear quarter of the vehicle, behind the bumper fascia.

Floor Carpet

The one-piece floor carpet goes over both the front and the rear floor pans.
