GMC 2012 Canyon Owner's Manual page 346

Do not use cleaners that increase
gloss, especially on the instrument
panel. Reflected glare can decrease
visibility through the windshield
under certain conditions.
Keep belts clean and dry.
Do not bleach or dye safety belts.
It may severely weaken them. In
a crash, they might not be able to
provide adequate protection.
Clean safety belts only with mild
soap and lukewarm water.
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.
