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 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.
.Do not use a floor mat if the vehicle is
not equipped with a floor mat retainer on
the driver side floor.
.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.
Button Retainer
Some vehicles have floor mats with a
button-type retainer.
Removing and Replacing the Floor Mat 1. Pull up on the rear of the floor mat to unlock each retainer and remove.
2. Reinstall by lining up the floor mat retainer openings over the carpet
retainers and snapping into position.
3. Make sure the floor mat is properly secured in place. Verify the floor mat
does not interfere with the pedals.
Cleaning Rubber Floor Mats (All-Weather
Mats and Floor Liners)
{Warning
Do not use cleaners that contain silicone,
wax-based products, or cleaners that
increase gloss on rubber floor mats/liners.
These cleaners can permanently change
the appearance and feel of the rubber
and can make the floor mats/liners
slippery. Your foot could slip while
operating the vehicle, and you could lose
control, resulting in a crash. You or
others could be injured.
Use a soft cloth and/or a brush dampened
with water to remove dust and loose dirt.
For more thorough cleaning, use a mild soap
solution.
