Vehicle Care / Appearance Care / Floor Mats

If a floor mat is the wrong size or is not properly installed, it can interfere with the pedals.

Interference with the pedals can cause unintended acceleration and/or increased stopping distance which can cause a crash and injury. Make sure the floor mat does not interfere with the pedals.

Use the following guidelines for proper floor mat usage.
The original equipment floor mats were designed for the 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 pedals. 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.
