320 Vehicle Care
Floor Mats
{Warning
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 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.
Removing and Replacing the
Floor Mat
The driver side floor mat is held in
place by two retainers.
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 snap into
position.
3. Make sure the floor mat is properly secured in place.
Verify the floor mat does not
interfere with the pedals.
