Spray-In Bedliner Care; Cleaning Exterior Lamps/Lenses And Emblems; Air Intakes; Windshield And Wiper Blades - GMC 2014 Sierra Owner's Manual

The bright metal moldings on the
vehicle are aluminum. To prevent
damage always follow these
cleaning instructions:
Be sure the molding is cool to
the touch before applying any
cleaning solution.
Use a cleaning solution
approved for aluminum. Some
cleaners are highly acidic or
contain alkaline substances and
can damage the moldings.
Always dilute a concentrated
cleaner according to the
manufacturer s instructions.
Do not use chrome cleaners.
Do not use cleaners that are not
intended for automotive use.
Use a nonabrasive wax on the
vehicle after washing to protect
and extend the molding finish.
A spray-in bedliner is a permanent
coating that bonds to the truck bed
and cannot be removed. Promptly
rinse the bedliner surface following
a chemical spill to avoid permanent
damage.
Spray-in bedliners can fade from
oxidation, road dirt, heavy-duty
hauling, and hard water stains.
Clean it periodically by washing off
the loose dirt and using a mild
detergent. To restore the original
appearance, apply the bedliner
conditioner available through your
dealer.
Using silicone-based products
may damage the bedliner, reduce
the slip-resistant texture, and
attract dirt.
Use only lukewarm or cold water, a
soft cloth, and a car washing soap
to clean exterior lamps, lenses, and
emblems. Follow instructions under
"Washing the Vehicle" in this
section.
Clear debris from the air intakes,
between the hood and windshield,
when washing the vehicle.
Clean the outside of the windshield
with glass cleaner.
Clean rubber blades using a lint-free
cloth or paper towel soaked with
windshield washer fluid or a mild
detergent. Wash the windshield
thoroughly when cleaning the
blades. Bugs, road grime, sap, and
a buildup of vehicle wash/wax
treatments may cause wiper
streaking.
Replace the wiper blades if they are
worn or damaged. Damage can be
caused by extreme dusty
conditions, sand, salt, heat, sun,
snow, and ice.
