Vehicle Care Use the following guidelines for proper floor mat usage: . 10-99 Removing and Replacing the Floor Mats Pull up on the rear of the floor mat to unlock each retainer and remove. The original equipment floor mats were designed for your vehicle. If the floor mats need replacing, it is recommended that GM certified floor mats be purchased. Non-GM floor mats may not fit properly and may interfere with the accelerator or brake pedal. Always check that the floor mats do not interfere with the pedals. Use the floor mat with the correct side up. Do not turn it over. Do not place anything on top of the driver side floor mat. Use only a single floor mat on the driver side. Do not place one floor mat on top of another. . . . Reinstall by lining up the floor mat retainer openings over the carpet retainers and snap into position. Make sure the floor mat is properly secured in place. Verify the floor mat does not interfere with the pedals. .
