2. Setup & Installation
Installing your WeatherTech FloorLiners is a straightforward process designed for ease of use. Follow these steps for proper installation:
- Remove any existing floor mats from your vehicle.
- Clean the vehicle's carpeted floor area thoroughly before placing the new FloorLiners.
- Carefully position the WeatherTech FloorLiner into the corresponding footwell (driver's side, passenger's side, or rear). Ensure it is fully seated and aligned with the contours of the vehicle's floor.
- For front mats, slide the liner into place underneath the pedals.
- Secure the FloorLiner using your vehicle's factory retention devices, if applicable. WeatherTech FloorLiners are designed to work with these systems. If your vehicle does not have factory retention devices, or if supplemental devices are provided, use them as instructed.
- After installation, always check that the FloorLiner does not interfere with the full operation of the accelerator, brake, or clutch pedals. Ensure there is no obstruction to pedal movement.

WeatherTech FloorLiners are designed for durability and a precise fit, minimizing common issues. However, if you encounter any concerns, consider the following:
- Improper Fit: Double-check that the correct FloorLiner is placed in the correct footwell (driver's side, passenger's side, rear). Ensure no previous mats are underneath.
- Movement/Slipping: Verify that the FloorLiner is properly secured with all available retention devices. Ensure the carpet underneath is clean and dry.
- Odor: New products may have a slight odor initially. This typically dissipates quickly with ventilation.
- Deformation: In rare cases, extreme temperature changes during shipping might cause minor deformation. Placing the liner in direct sunlight for a short period can help it regain its original shape.
