9-6 Driving and Operating
Do not cover the opening in the
front bumper.
Do not modify the cover. The
winter cover does not cover
some sections of the front of the
vehicle to provide enough
airflow.
When the winter cover is used,
the outside air temperature
display may not function
properly.
Keep the underside of the winter
cover as clean as possible.
Remove monthly or as
necessary and clean away dust
and debris.
Use only a mild soap to clean.
Do not use harsh soap, strong
detergents, or vinyl protectant/
sealant type products as they
may damage the special finish.
Allow the winter cover to dry
completely before reinstalling.
Installation Instructions
When first trying to fit the cover, it
may appear to be undersized but
will stretch during installation to
ensure a tight fit. The initial
installation of the cover is best
performed when the winter cover
is warm.
Installation (Chevrolet Pickup)
1. The white label must be at the
top and back of the cover.
