We recommend the use of Genuine Mazda floor mats.
WARNING
Make sure the floor mats are hooked on the retention pins to prevent them from bunching up under the foot pedals:
Using a floor mat that is not secured is dangerous as it will interfere with the accelerator and brake pedal operation, which could result in an accident.
Do not install two floor mats, one on top of the other, on the driver's side:
Installing two floor mats, one on top of the other, on the driver's side is dangerous as the retention pins can only keep one floor mat from sliding forward.
If using an all weather mat for winter use always remove the original floor mat.
Loose floor mat(s) will interfere with the foot pedal and could result in an accident.

When setting a floor mat, position the floor mat so that its grommets are inserted over the pointed end of the retention posts.
